▼ Objective: Previous studies evaluating premolar
extraction influence on third molar angulation have combined first
and second premolar extractions into a common extraction group. By
combining the extraction groups, individual influences of each
premolar have been negated. Separating the 2 extraction groups
allows the influence of each premolar to be individually evaluated.
Methods: In this retrospective study, 90 patients were divided into
3 groups of 30 patients each. Groups were determined by extraction
pattern (nonextraction, first premolar extraction, second premolar
extraction). The long axes of the second and third molars were
traced on initial and final panoramic radiographs. The angulation
change between the molars was determined between initial and final
angulations. Results: There was not a significant difference in
uprighting between the 3 treatment groups. Conclusion: Although the
rationale that extraction of premolars could create a greater
amount of retromolar space for third molars to upright and erupt
into occlusion, our findings did not support this
rationale.

▼ Background: Post‐treatment tooth movement is an
inevitable component of orthodontic treatment and it depends on
many factors. Favorable post‐orthodontic movement is often referred
to as “settling.” A better knowledge of how teeth tend to settle
may help the orthodontic practitioner in choosing types of
retention for different cases. Many studies have shown an overall
improvement in occlusal relationships using both the ABO OGS and
PAR grading scales. However, past studies have mainly focused on
occlusal contacts and near occlusal contacts using wax bites. Fewer
recent studies have evaluated the measurements of the settling
dentitions in 3 dimensions. Purpose: The purpose of this study was
to accurately assess the occlusal settling which takes place from
the day of de‐bond until retainer delivery 7-10 days later.
Methods: Orthodontic plaster models were acquired for 24
consecutively debonded patients at two timepoints: debond and
retainer delivery. These were scanned using a 3D bench‐scanner.
These scanned surfaces were superimposed in 3D to evaluate changes
between time point for each of the 24 patients. Results: Although
each patient showed slightly different settling characteristics,
there were many similarities. Many patients posterior teeth
exhibited an extrusive movement as well as lingual or facial
tipping. Many patients also had extrusion and tipping of the lower
anterior teeth. The method used for obtaining occlusal contact
points in this study was found to be invalid between trials of the
same time point. Conclusions: Occlusal settling varies from patient
to patient depending on the post‐orthodontic tooth position. Some
general trends could be seen in the posterior teeth of both the
maxillary and mandibular arches as well as the anterior teeth of
the mandibular arch. 3D analysis of scanned models is a valid
method for qualitatively analyzing post treatment orthodontic
settling movements.

▼ Introduction: Root resorption following orthodontic
treatment is common and often does not have deleterious effects on
the longevity of the teeth. Previous methods of imaging root
resorption include panoramic radiographs and periapical
radiographs. Cone Beam Computed Tomography (CBCT) is now available
to assess root resorption in 3 dimensions. Research Objective: To
understand the 3 dimensional pattern of root resorption on
maxillary incisors that underwent orthodontic treatment.
Additionally, is there a correlation between direction of tooth
movement and pattern of root resorption? Methods: 25 patients (100
teeth) were involved in this study. Cone Beam Computed Tomography
(CBCT) scans which had been taken pre and post treatment were
analyzed to assess root resorption pattern and direction of
movement. Results: Root resorption can occur not only at the apex
in a vertical manner, but also at the mesial, distal, palatal and
facial surfaces of the root. When the teeth moved in the apical
direction (31 instances) root resorption on the isolated apical
surface of the root was found 94% of the time (29 instances). When
the teeth moved in the palatal direction (65 instances) root
resorption on the isolated palatal surface of the root was found
20% of the time (13 instances). Conclusion: Root resorption was
observed on the surface of root movement, however it was also
observed on surfaces not related to root movement. The clinician
may consider the direction of root movement in diagnosis and
treatment planning of orthodontic treatment, and in the assessment
of risk factors for root resorption.

▼ INTRODUCTION: Randomized controlled trials (RCT) by
proper design, conduct, analysis and reporting, provide reliable
information in clinical care. Reporting of RCT abstracts is of
equal importance as there is evidence that many clinicians will
change their clinical decisions based on RCT abstracts. The
reporting quality of RCT abstracts has been suboptimal. It is not
clear whether the reporting quality is related to the journal
metrics. The main objective of this study is to conduct a
cross-sectional survey to evaluate the reporting quality of
randomized controlled trials of periodontal diseases in journal
abstracts and to perform a bibliometric analysis. The null
hypothesis was there is no association between the journal metrics
(5-Year Impact Factor, Eigenfactor® Score and Article Influence®
Score), abstract metrics (Word Count, Number of authors), journal
endorsement of Consolidated Standards of Reporting Trials (CONSORT)
and the overall quality of reporting of CONSORT RCT modified
checklist questions. ❧ MATERIALS AND METHODS: CONSORT RCT Abstract
Extension checklist with explanation and elaboration was utilized
and modified to assess the quality of reporting of RCT abstracts of
periodontal diseases in the journal abstracts in the year 2012.
Bibliometric analysis of journal metrics (5-year impact factor,
Eigenfactor® Score and Article Influence® Score) and abstract
metrics (number of authors, abstract word count), the geographic
distribution and the CONSORT endorsing journal abstracts was
compared to the reporting quality of RCT abstracts in periodontal
diseases. Calibration and intra-rater agreement was done prior to
the data collection and analysis. A second reviewer was consulted
for independent evaluation and clarification as needed. For
descriptive analysis, the values of continuous variables were
expressed as median and interquartile ranges and as proportion
percent for binary categorical variables. For association analysis
between binary (yes/no) response variable and the continuous
variable, Mann-Whitney test (for independent samples) was used. For
examining the association between 2 categorical variables, Fishers
exact test was used. Chi-square test was performed to examine the
association between two sets of binary response variables (yes/no).

▼ Background: In a recent study by Tong et al. (2012),
76 subjects with near-normal occlusion, who were never
orthodontically treated, were studied using CBCT to measure the
mesiodistal angulation and faciolingual inclination of each whole
tooth (crown and root) in 3-dimensional space. The study provided a
standard for positioning each whole tooth properly in the arches. ❧
Purpose: In this study, a subset of the 76 subjects was studied
after they were orthodontically treated with non-extraction
treatment. The purpose of this study is to determine the changes in
mesiodistal angulation and faciolingual inclination after
orthodontic treatment was rendered. ❧ Methods: Of the 76 patients
from the previous study, 24 of them also had CBCT records taken at
the completion of the non-extraction orthodontic treatment. Their
final CBCT records were digitized using the custom
University of
Southern California root vector analysis software program. Paired
t-tests were used to compare pre- and post-treatment values for
mesiodistal angulation and faciolingual inclination. ❧ Results:
Results of the paired
t-tests showed that there was a statistically
significant difference for the mesiodistal angulation value of
lower first molars and faciolingual inclination values of upper
second premolars and lower first molars after orthodontic treatment
was rendered. The range of change was larger and pattern of change
was more variable from tooth to tooth in mesiodistal angulation
than in faciolingual inclination measurement. ❧ Conclusion: The
mesiodistal angulation and faciolingual inclination of each tooth
was maintained throughout orthodontic treatment, except upper
second premolars and lower first molars. This may be due to
difficulty of determining proper band position for lower first
molars and poor visibility for bracket position of upper second
premolars. Bracket position may affect mesiodistal angulation more
than faciolingual inclination in the final outcome of
non-extraction treatment. More studies with larger sample sizes are
needed.

▼ The purpose of this project was to create an
educational tool to prepare patients for orthodontic treatment.
Previous studies have demonstrated a need for written material that
can introduce the concept of mechanics in an easily understood
format; the more acceptable this material would be to the patient,
the more likely the patient would be to actually read it. The model
of a fantasy fiction novel was used to ensure the relatability of
the project. Orthodontic ideas were introduced in order to promote
dialogue between doctor and patient; a factor necessary to increase
compliance and resultant treatment success.

▼ Strain-specific genes on genomic islands are often
acquired by bacteria via horizontal gene transfer (HGT), which may
enhance the fitness of the bacteria. Our laboratory has completed a
project to compare the genome content of 14 A.
actinomycetemcomitans strains recovered from periodontal health and
disease. Numerous genomic islands of unknown functions were
identified. Some may be nonfunctional vestiges of HGT-acquired
genes that have undergone further mutations, while others may
function to enhance the virulence of the strains. This study
developed an approach to identify strain-specific genes that are
involved in growth and biofilm formation of A.
actinomycetemcomitans. Experimental variables that may affect the
assay outcomes were evaluated. Different approaches for data
analysis were also compared. Novel gene genetic protocols were used
to construct mutants for A. actinomycetemcomitans strain D7S-1.
These mutants were tested for their doubling time and biofilm
formation. Mutants with a deletion of a ~5 Kb genomic island
(designated as “285-island”) exhibited faster doubling time than
the wildtype D7S-1 or other mutants. Deletion mutants restored with
a copy of the 285-island exhibited doubling time similar to that of
wildtype strain D7S-1. Growth of strain-specific genes in pH 4.0
was also tested and two groups of the mutants were distinguished
based on their ability to grow at pH 4.0. This is the first study
that demonstrated a function of any strain-specific genomic island
(except serotype-specific gene cluster) of A.
actinomycetemcomitans, and validated our approach to screen for
functionally important genomic islands among A.
actinomycetemcomitans strains.

▼ Objective: Progress models are commonly made during
the detailing and finishing stages of orthodontic treatment with
alginate impressions and plaster. Three-dimensional intraoral
scanners, such as Align Technology Inc.’s iTero, can be used in
place of traditional models. The objective of this study was to
assess whether the three-dimensional models were useful in
visualizing treatment progress per the American Board of
Orthodontics (ABO) final model grading system. Methods: In this
prospective study, 20 patients in the detailing and finishing
stages of orthodontic treatment were scanned using the iTero
intraoral scanner. 10 ABO certified faculty orthodontists of the
University of
Southern California used the three-dimensional model
to assess treatment progress and completed a survey to determine
which sections of the final model grading system were easy or
difficult to visualize. Results: Assessing treatment progress and
visualizing tooth alignment (rotation), occlusal contacts, overjet,
and overbite were easily done. Visualization of marginal ridge
heights, visualization of posterior torque, and manipulation of the
models were the most difficult. Conclusion: Although all faculty
reported that the majority of the ABO final model grading system
were easy to visualize, sixteen out of twenty reports that both
types of models are equally useful for assessing orthodontic

▼ Background: Maxillary buccal bone thickness is
critical in determining bone and soft tissue response after
extraction. Two millimeters of buccal bone may be optimal for
proper hard and soft tissue healing for immediate implant
placement. ❧ Objective: The purpose of this study was to utilize
cone beam computerized tomography (CBCT) to (1) measure the
horizontal width of buccal alveolar bone overlying healthy
maxillary first and second premolars, (2) measure the distance from
the CEJ to the bone crest, and (3) evaluate the impact of
demographic factors in relation to the independent variables. ❧
Methods: Tomographic data from 65 (F=39, M= 26) consecutively
selected patients (age range: 10 - 64 y/o) were evaluated twice by
one examiner. Buccal bone width was assessed at levels 1.0 -10.0 mm
apical to the alveolar bone crest. The distance from the CEJ to
alveolar bone crest was also measured. ❧ Results: A total of 260
premolars were evaluated. The percent of teeth with buccal bone ≥ 2
mm at levels 1,2,3,4 and 5 mm from the bone crest was 6.3, 8.5,
17.7, 20 and 20% respectively for first premolars, and 20.1, 32.3,
50.8, 51.5 and 46.2% respectively for second premolars. The overall
mean thickness of bone was 1.58 mm for the first premolars and 1.94
mm for the second premolars. Percentage widths (≥ 2 mm) observed at
levels 1 to 5 mm were 14.48% (first premolars) and 40.2% (second
premolars). The overall (levels 1 to 10 mm) percentages were 22.35%
and 43.81% for the first and second premolars respectively.
Fenestrations were found in 3% of the first premolars and in 1.5 %
of the second premolars. The mean distance between the CEJ and bone
crest was 1.96 mm (range: 0.7 - 3.45 mm) for the first premolars
and 1.71 mm (range: 0.4 - 2.9 mm) for the second premolars.
Statistical significance was evident when age and CEJ to bone crest
distance were correlated. ❧ Conclusion: The study’s statistics
suggested a generally greater (≥ 2 mm) alveolar buccal bone
thickness overlying the maxillary second premolars, when compared
to the first premolars at all levels (1- 10 mm from bone crest).
The first premolar sites exhibited an apical gradual increase in
alveolar bone thickness. However, the second premolar sites’
maximum buccal bone thickness (≥ 2 mm) was mostly at the 4 mm level
from the alveolar bone crest. The alveolar buccal bone thickness
generally increased the more posterior the tooth is in the arch.
The distance between the CEJ to the bone crest is a wide range, not
a constant uniform measurement. ❧ In order to achieve optimal soft
and hard tissue healing, a minimum of 2 mm of buccal bone may be
required when placing implants immediately after extractions
(Qahash et al. 2008, Spray et al 2000, & Grunder et al. 2005).
Immediately placed implants are usually positioned 2 to 3 mm
sub-crestally. The CBCT images in the present study revealed that
buccal alveolar bone width of maxillary premolars was mostly less
than 2 mm, but increased in the apical and posterior directions.
These results indicate an increased risk of buccal implant…

▼ Objective: The purpose of this study is to compare the
shear bond strengths of standard single mesh, sandblasted and
laser‐etched orthodontic bracket bases. Our H₀ hypothesis is there
is no difference in shear bond strength of standard single mesh,
sandblasted brackets and laser‐etched orthodontic bracket bases. ❧
Methods: To compare bond strength of commercially available
orthodontic brackets thirty‐six brackets were divided into three
equal groups. Single mesh control (n=12), sandblasted bracket bases
(n=12), laser‐etched bracket bases (n=12) were bonded to a
composite disk and subjected to shear bond strength tests using an
Instron Universal Testing Machine. ❧ Results: Shear bond strength
(SBS) for all three groups ranged from 12.25 MPa to 34.99 MPa.
Control group (single‐mesh) SBS ranged from 16.79 to 30.00 MPa
(mean = 24.1072 MPa), sandblasted group ranged from 21.05 to 34.99
MPa (mean =30.8143 MPa) and the laser‐etched group ranged from
12.25 to 29.43 MPa (mean =21.7709 MPa). A one‐way ANOVA with
post‐hoc Tukey B for group wise comparison was performed at α=0.05.
❧ Conclusion: In this study, the surface treatment of orthodontic
bracket bases using sandblasting resulted in significantly higher
shear bond strength compared to standard single mesh and
laser‐etched bracket bases. When comparing the shear bond strength
of laser‐etched and control mesh bracket bases, there was no
significantly different from each other.

▼ INTRODUCTION: The timing of treatment for Class II
malocclusion has been heavily studied yet still remains to be a
controversial clinical issue. This study specifically evaluates the
ability of Class II growth modification to prevent the need for
premolar extraction and the effect it has on cephalometric
measurements. ❧ MATERIALS AND METHODS: Patient records from the
private practice office of an American Board of Orthodontics
diplomate in
Southern California were evaluated for this study. A
total of 106 patient records were examined, 36 were treated in
two-phases and 70 were treated in a single-phase. The complete
records of each patient were analyzed to compare premolar
extraction rates between the two treatment groups and their
resulting cephalometric measurements. ❧ RESULTS: There was no
significant difference in extraction rate between two-phase and
single-phase treatment. The single-phase treatment group had an
extraction rate of 18.6% (13 out of 70 patients) while the
extraction rate for the two-phase group was 13.9% (5 of the 36
patients)(p-value 0.543). The change in ANB was the only
significant cephalometric difference between two-phase and
single-phase treatment with more change occurring in two-phase
treatment. ❧ CONCLUSION: The results of this study conclude that
two-phase Class II treatment does not reduce the rate of premolar
extraction by a significant amount. In addition, early orthodontic
treatment does not affect cephalometric outcomes, with the
exception of ANB.

▼ Objectives: Current methods of orthodontic oral
hygiene instruction include face-to-face presentations, printed
materials, videos, and other technologies. In an orthodontic
setting where the majority of patients are in their adolescence,
these methods tend to bore them and it is hard to keep their
attention for a sufficient amount of time to properly instill good
oral hygiene techniques and principles. This project seeks to use
methods and technologies familiar and liked by them in order to
have a more lasting effect on their oral hygiene practices and
behavior. ❧ Purpose/hypothesis: To create a novel method to teach
orthodontic oral hygiene instructions using methods familiar and
liked by adolescents, with the goal of aiding them in the
internalization of the principles through active participation such
that it results in better hygiene practices by these patients. ❧
Procedures/Data/Observations: An iPad application was created using
a team of dentists, designers and computer programmers. Surveys and
brainstorming sessions done with experts in the field revealed
which principles to be essential, as well as the types of modules
to place into the application. ❧ Conclusions/Applications: The
application created is the first of its kind in the world and
teaches adolescents in an interactive manner how to better care for
their teeth. A study on the efficacy of the iPad application will
be performed in the future.

▼ Background: In vitro lab investigations are useful to
gain insights into how different bracket bases perform under
controlled conditions. It is possible to evaluate the
characteristics of these bases to design one that is both,
clinically effective and affordable to manufacture. ❧ Purpose: To
test the effects of base morphology and preparation on bond
strength, using sham lingual brackets and a customized resin
substrate for bonding. ❧ Methods: Eighty sham lingual brackets were
divided into four equal groups (n=20): flat base with sandblasting,
flat base with laser-etching, custom base with sandblasting, and
custom base with laser-etching. The brackets were bonded to a resin
substrate using a custom jig and tested for bond strength. ❧
Results: The brackets with a custom base and laser-etching showed a
significantly lower bond strength when compared to both sandblasted
groups. All groups, however, had acceptable bond strengths. ❧
Conclusion: When comparing different sham lingual brackets, one
that has a custom base or preparation with laser etching may not
have a greater bond strength than a base that is flat and
sandblasted. All bracket types demonstrated acceptable performance,
however, and may be considered for clinical use. Further clinical
study of custom brackets may be hindered by issues associated with
feasibility and increased costs.

▼ Introduction: The accuracy of orthognathic surgery
skeletal prediction has been studied in the past. This study
evaluates accuracy of orthognathic surgery skeletal prediction
using a novel superimposition method based on a regional,
voxel-based approach. ❧ Methods: The pre- and post-surgical cone
beam computed tomography (CBCT) records (n=44) of Class III
surgical patients were superimposed, and a standard
three-dimensional Cartesian coordinate system was defined. The
transverse, anteroposterior, and vertical movement of clinically
defined maxillary and mandibular landmarks were calculated based on
their pre- and post-surgical positions. These surgical changes were
compared with the predicted movements determined in the model
surgery. A statistical analysis was undertaken to validate landmark
identification and the accuracy of the surgical predictions. ❧
Results: We were able to successfully use the voxel based
superimposition technique to compare surgical skeletal movements
with movements predicted at the time of model surgery. The
difference between actual and planned surgical changes was
statistically significant (p < 0.05) for transverse and vertical
movement of the maxillary left First Molar and for vertical
movement of the maxillary left Canine. However, the mean
differences between actual and planned surgical changes for these
statistically significant findings were all less than 0.5 mm. ❧
Conclusions: The skeletal movements planned at time of model
surgery were reproduced surgically with a clinically insignificant
level of error. Utilizing voxel based superimposition and a
landmark based treatment outcomes approach allows us to isolate
error in a way not available in methods that use cephalometrics or
segmentation derived surface models. The author’s personal
experience with the imaging tools utilized in this study was that
they provide automated, accurate, and fast superimpositions, which
should be seriously considered by those who aim to quantitatively
evaluate three-dimensional treatment outcomes.

▼ Background: Facial esthetics is an important
motivating factor for many patients seeking orthodontic treatment.
Traditionally in orthodontics, facial profiles have been evaluated
using cephalometrics and repose soft-tissue analysis. In this study
we want to evaluate the significance of the profile soft-tissue
analysis when the patient is smiling.; Purpose: Our purpose is to
evaluate and compare the anteroposterior relationship of the
maxillary central incisors to the forehead in adult white females
with harmonious profiles versus adult white female orthodontic
patients.; Methods: 94 photographic images of adult white females
with good facial harmony (control sample) were compared with 150
photographs of adult white females seeking orthodontic treatment
from 3 separate offices (study sample). All images smiling profile
images had the maxillary central incisors and the forehead in full
view. The images were adjusted and rotated to the upright head
position. Reference lines were drawn to measure the anteroposterior
positions of the maxillary central incisors as well as forehead
inclinations.; Results: Our results indicate that there is a
significant difference in anteroposterior position of maxillary
central incisor between the control sample (harmonious profiles)
and each office [control and office 1 (p=.002), control and office
2 (p=.000), and control and office 3 (p=.004)]. ANOVA and
Nonparametric analysis indicate that our results are significant.
Also there was a significant correlation in the control sample (R2
= 0.641) between anteroposterior incisor position and forehead
inclination, however none in the study samples. The most esthetic
maxillary central incisor position, between FFA point and glabella,
was highest in the control sample (94%), but much less in the three
offices (Office 1 = 22%, Office 2 = 30%, Office 3 = 30%).;
Conclusion: The forehead can be confirmed as a reliable landmark
for assessing the facial profile for adult white females as it
relates to anteroposterior maxillary central incisor position
relative to FFA. Treatment goals should include a harmonious
relationship between the anteroposterior position of maxillary
central incisors and the forehead for adult white female
patients.

▼ Introduction: The purpose of this study was to develop
a new methodology to visualize in 3 dimensions the whole teeth,
including the roots, at any moment during orthodontic treatment
without the need for multiple cone‐beam computed tomography (CBCT)
scans. Methods: An extra‐oral typodont model was created using
extracted human teeth placed in a wax base. These teeth were
arranged to represent a typical malocclusion. Initial records of
the malocclusion, including CBCT and intra‐oral surface scan were
taken. Threshold segmentation of the CBCT was performed to generate
a 3‐dimensional virtual model. This model and the intra‐oral
surface scan model were superimposed to generate a complete set of
digital composite teeth composed of high resolution surface scan
crowns sutured to CBCT roots. These composite teeth were
individually isolated from their respective arches for single tooth
manipulation. Orthodontic treatment for the malocclusion typodont
model was performed, and post‐treatment intra‐oral surface scans
before and after bracket removal were taken. A CBCT scan after
bracket removal was also obtained. The isolated composite teeth
were individually superimposed onto the post‐treatment surface scan
creating the expected root position setup. In order to validate
this setup, it was compared with the post‐treatment CBCT scan which
contains the true position of the roots. Color displacement maps
were generated to confirm accurate crown superimposition and to
measure the discrepancy between the expected and true root
positions. Results: Color displacement maps through crown
superimposition showed differences between the expected root
positions and true root positions to be 0.1678mm ± 0.3178mm for the
maxillary and 0.1140mm ± 0.1587mm for the mandibular in the
presence of brackets. Once the brackets were removed, differences
of 0.1634mm ± 0.3204mm for the maxillary and 0.0902mm ± 0.2505mm
for the mandibular were found. Conclusions: A new reliable approach
was demonstrated in an ex‐vivo typodont model to have the potential
of tracking the 3‐dimensional positions of the entire teeth
including the roots, with only the initial CBCT scan and
consecutive iTero scans. Since the presence of brackets in the
intra‐oral scan had minimal influence in the analysis, this method
can be applied to any stage of orthodontic treatment.

▼ The primary purpose of this retrospective, exploratory
study was to compare three-dimensional (3D) diagnostics (cone beam
computed tomography, CBCT) to two-dimensional (2D) diagnostics
(digital panoramic X-ray) in the assessment of root shape and
direction of dilacerations in the six maxillary anterior teeth.
Panoramic and CBCT images of 50 orthodontic patients were obtained
before treatment. Each image was evaluated to assess the shape of
the roots and the direction of dilacerations in the six maxillary
anterior teeth. In calculating method error, replicate measurements
were taken 2 weeks apart on 10 subjects for all variables. An
intraclass correlation coefficient (ICC; a two-way mixed effect
model) was then calculated on the recorded measurements to
determine the level of observer reliability. ICC’s ranged from .646
to .820 for 2D and .756 to 1.000 for 3D. The frequency of root
shape was significantly different between 2D and 3D images by Kappa
correlation coefficients. The majority of root dilacerations
occurred directly distal or distal lingual. Additionally, nearly
25% of the canines' apices were not identifiable in 2D images, but
were identifiable in 3D images. There were no significant
differences recorded between the two ethnic groups by chi-square
analysis. For all statistical tests, significance was established
at α = .05. With CBCT images root shapes could be assessed and the
direction of dilacerations evaluated. With panoramic images this
assessment was not always possible. Sometimes the roots of teeth
would be impossible to evaluate from panoramic x-rays because of
overlying structures and artifacts. CBCT was effective for
detecting root shapes and dilacerations in vivo and allowed
three-dimensional evaluation of dental roots without overlapping
images.

▼ Background: Observational studies intend to examine
variables in a population with hopes of characterizing any
potential associations. Thus, the quality of reporting of
observational studies is important in evidence-based clinical
decision-making processes. Comparison of the reporting quality to
established standards can help identify short comings of a study
and aim to improve quality of reporting and relevance of the
published data in clinical decision making. ❧ Purpose: To assess
the quality of reporting of observational studies in a widely read
periodontology journal, the Journal of Periodontology (JoP). ❧
Methods: Electronic search, supplemented by hand search of JoP was
completed independently and in duplicate by two reviewers. The
combined strengthening the reporting of observational studies in
epidemiology (STROBE) statement and checklist (consisting of 22
criteria) were used to evaluate the reporting quality of the
selected observational studies from JoP published in the year of
2013. ❧ Results: STROBE items 9 (publication bias), 10 (study size
determination), 12e (sensitivity analysis), 13c (diagram usage),19
(limitations), and 22 (funding of the study) were consistently
scored low in the journal, whereas items 2 (background), 5 (setting
of the study), 6 (participants of the study), 8 (data measurement),
15 (outcome data), and 18 (key results) were consistently scored
high. ❧ Conclusion: The quality of reporting of observational
studies in JoP can be improved as compared to the STROBE
statement.

▼ BACKGROUND: Overbite is the vertical relation of the
upper to lower incisors. Normal overbite is considered normal
within 1-3 mm, and excessive over 4 mm. ❧ OBJECTIVE: Goal of this
study is to determine the mechanism of overbite correction with
customized appliances. ❧ MATERIALS AND METHODS: Cephalometric
radiographs for 39 consecutive cases with >4 mm. of overbite
were digitized and traced in Dolphin Imaging Software. In order to
assess changes, tracings were superimposed by the Bjork structural
method. All cases were from a single orthodontic office in Germany
and treated with Incognito lingual system. Sample was divided into
growing and non-growing subgroups according to chronological age.
Descriptive statistics and comparison between subgroups are
presented. ❧ RESULTS: Treatment and growth changes in growing
patients included: 1) molar extrusion 2) anterior incisor intrusion
3) anterior incisor flaring. Treatment and aging changes in growing
patients included: 1) minimal molar extrusion 2) anterior incisor
intrusion 3) greater anterior incisor flaring 4) mandibular
autorotation. The difference between groups was the increase in
facial heights. ❧ CONCLUSIONS: Growing and non-growing differed (as
expected) in the increase of facial heights. Incisor inclination
depended on the desired inclination designed into the custom
lingual appliance as opposed to increased inclination (flared)
incisors often reported in other studies. Overbite correction was a
combination of molar extrusion, incisor intrusion, incisor flaring,
and mandibular autorotation. Future research is needed to define
the target overbite for specific patients in order to allow for
optimum function.

▼ BACKGROUND: CBCT opens new opportunities for alveolar
bone studies by allowing precise measurements of teeth and their
alveolar housing. This could provide new insights into the role of
tooth and bone geometry in normal occlusions. ❧ PURPOSE: To
determine whether correlations are present between torque of teeth
and torque of bone in patients with normal occlusion. ❧ METHODS:
CBCT images of a sample of 76 near-normal cases were acquired.
Maxillary and mandibular teeth were digitized. Alveolar process
centers were also digitized at each interproximal area. Torque was
calculated and compared for all teeth and all interproximal areas.
Paired
T-tests and Wilcoxon signed rank tests were used to compare
(1)right and left measurements (2) bone and tooth measurements. The
significance level was adjusted for multiple comparisons with the
Bonferonni correction to keep the overall type 1 error at alpha
=(0.05/7=0.0071). ❧ RESULTS: We found that bone and teeth torque
values follow similar trends. ❧ CONCLUSIONS: There are correlations
between the inclinations of teeth and the inclinations of bone.
This information can be used in addition to crown standards for
positioning the entire tooth, crown and root, within
bone.

▼ Background: Micrognathia presents in many craniofacial
disorders and may have immediate and long-term effects on the
neonatal airway. Airway obstruction is a critical condition that
often requires immediate intervention—ranging from intubation to
tracheostomy, and mandibular distraction osteogenesis. ❧
Objectives: 1) Evaluate long-term development—assessed by
cephalometrics analysis—of Pierre Robin Sequence (PRS) patients
that underwent mandibular distraction osteogenesis (MDO) to
alleviate airway obstruction. 2) Identify changes in growth
patterns in this patient population as compared to published
age-matched norms and age-matched untreated PRS patients. 3)
Identify respiratory changes through polysomnography. ❧ Patients
and Methods: A retrospective chart review and analysis was
performed following approval of the Institutional Review Board
(IRB). The sample consisted of 12 non-syndromic PRS patients
diagnosed with respiratory distress or respiratory failure (based
on polysomnography data) that had undergone mandibular distraction
osteogenesis at Children’s Hospital Los Angeles (Los Angeles,
Calif.) PSG was performed to document any changes in status of the
breathing disorder. Lateral cephalograms were taken and digitally
traced using a Bjork analyses and USCF Cranio analysis, and growth
comparisons were produced. ❧ Results: There was a statistically
significant increase in gonial angle (ML/RL) of the Pierre Robin
sequence patients treated with MDO (PRSMDO) compared to untreated
PRS patients. The mandibular ramus length (Ar-GO) was significantly
shorter, and mandibular body (Go-Gn) was significantly longer in
PRSMDO patients. Chin prominence (SN-Pg) was greater in PRSMDO
patients. Maxillomandibular sagittal relationship (ANB) in the
tested sample had a statistically significant closer approximation.
Upper face height (N-ANS), lower face height (ANS-Gn), maxillary
length (Co-A), and mandibular length (Co-Gn) were all shorter with
statistical significance. All other measurements showed no
statistical significance. ❧ Conclusion: The candidates for early
intervention with MDO represent the most severe micrognathia cases.
Further study of these patients is needed to determine if the more
vertical growth vector observed in these patients will lead to a
dolichofacial profile as the patient matures. Should an extremely
high gonial angle lead to an anterior skeletal and dental open bite
paired with a non-pleasing soft tissue profile, these patients—once
skeletally mature—may require two-jaw orthognathic surgery to
address their facial disharmony.

▼ Introduction: The pros and cons of early two-phase
treatment of Class II malocclusion have been examined recently.
This study examines how growth modification will affect premolar
extraction rates as well as final cephalometric outcomes.; Methods:
Patients (n=46; ages 7-17) from a private practice of an American
Board of Orthodontics diplomat in
Southern California were
evaluated. 27 patients were treated in a single-phase, and 19 were
treated in two-phases. Full records of each patient were examined
to compare premolar extraction rates in the permanent dentitions
and resulting cephalometric measurements in single- and two-phase
treatment groups.; Results: Out of the 27 patients undergoing
single-phase treatment, 13 out of 27 (48.1%) required premolar
extractions. 6 out of the 19 (31.6%) two-phase treatment patients
needed extractions. Extraction rate between the two groups proved
not to be significant. (p=0.261) Final cephalometric changes show
no significant changes between the two groups.; Conclusions: Early
orthodontic intervention in Class II malocclusion does not provide
reduced rates in premolar extraction and does not affect
cephalometric outcomes.

▼ BACKGROUND: As of today, the majority of the evidence
to support clinical periodontal practice and implant dentistry is
derived from observational studies. However, interpretation of data
from observational studies in the periodontal literature is often
limited by suboptimal quality of reporting. The need for
transparent reporting of scientific research in general led to
influential statements and the development of guidelines to direct
researchers and improve the quality of reporting studies. Since the
development of STROBE statement in 2007, there have been attempts
to improve the quality of reporting of observational studies
published in periodontal journals. However, it is still not clear
which items from the statement are well reported and which items
requires further improvement. ❧ AIM: The aim of this study was to
conduct a cross sectional survey on the quality of reporting on
published analytical observational studies in one of the major
journals in periodontology using a modified checklist of the STROBE
statement. The most recent issues published in a journal with the
highest impact factor (IF) in periodontology and implant dentistry,
the Journal of Clinical Periodontology, were reviewed. The focused
question was: what is the quality of reporting of observational
studies in periodontology and implant dentistry in Journal of
Clinical Periodontology? ❧ METHODS: An online search using MEDLINE
followed by hand search of JCP was performed to identify
observational studies published between January 01, 2014 and
December 31, 2014. Inclusion criteria: analytical human
observational studies (cohort, case-control and cross-sectional).
All experimental studies or articles reporting on case
series/reports, animal /cadaver studies, and in vitro studies were
excluded. In addition, systematic reviews or meta-analysis were
excluded. ❧ The STROBE checklist was devised to determine the
quality of reporting of observational studies in all issues of 2014
in JCP. Each article was systematically analyzed to evaluate
whether the items named in the checklist are present or absent.
Outcome measurements were extracted and descriptive statistics used
to present data of STROBE compliance. ❧ RESULTS: A total of 137
articles were published in the year of 2014 and following the title
and abstract screening 73 titles were excluded. The remaining 64
articles were then fully analyzed by the primary reviewer.
Following the full text screening, 13 additional articles were
excluded that did not meet the inclusion criteria. Total of 51
articles were included for the final analysis. The majority of the
included observational studies were cross-sectional, 25 articles
(49%). The remaining articles included 14 cohort studies (27%) and
12 case-control studies (24%). The reporting quality of the three
observational study designs were mixed. Generally, none of the
articles has fully adhered to the STROBE guidelines. The average
compliance for all the articles was 68.9%. The highest percentage
of compliance was found to be 84.3%, while the lowest value…

▼ Purpose: The objective of this study was to assess whether the iTero intraoral scanner can be used to assess orthodontic progress and identify common deficiencies. Methods: In this retrospective study, 22 patients in the detailing and finishing stages of orthodontic treatment were scanned using the iTero intraoral scanner. Scanned arches were then analyzed using ABO Cast-Radiograph criteria to objectively score each virtual model. The arches were analyzed twice within one week by the same individual using the same tools in the same location under the same conditions. Total and category scores were determined. Correlation statistics were used to detect statistically significant contributors to the overall score. Results: Occlusal contacts, occlusal relationships, and overjet were the most highly correlated predictors (statistically significant P<.01) of the final ABO Cast Evaluation score for the progress models. Assessing ABO grading criteria was reliably accomplished with the exception of buccolingual inclination. Conclusion: Virtual models created using the iTero digital intraoral scanner can reliably be used to assess orthodontic progress and visualize deficiencies.

▼ Introduction: The purpose of this study was to clarify
morphologic differences between Caucasian and African American
mandibular clinical arch forms in Class I, II, and III
malocclusions. Methods: The study included 60 Class I, 50 Class II,
and 50 Class III patients from the Caucasian group and 57 Class I,
26 Class II, and 17 Class III patients from the African American
group. Orthodontic study models were photocopied, scanned,
digitized, and measured (4 linear and 2 proportional). The dental
arches were classified into square, ovoid, and tapered forms to
compare the frequency distributions between the 2 ethnic groups.
Results: The Caucasians had a significantly smaller arch dimensions
than the African American, except for canine depth. African
Americans had a higher frequency of tapered arch forms. Conclusion:
There is a significant difference between frequency of arch forms
and arch dimensions of African American and Caucasian patients.
Specifically, there is no arch form unique to any of Angle
classification or ethnic group. The most frequent arch form seen in
Angle malocclusion groups was the tapered one, followed by the less
frequent ovoid and square ones.

▼ Background: Orthognathic surgery is difficult to plan
and execute for both the orthodontist and oral surgeon. Though
recent strides in technology and diagnostic tools have been made,
connecting these tools has not been accomplished in an efficient
manner. The advent of virtual surgical planning has brought a new
level of detail to surgery, but the execution is still difficult
when applied in a clinical setting. By combining 3D printing and
virtual surgical planning, a better resultant surgical result may
be achieved. ❧ Purpose: In this project, the purpose was to combine
existing methods of surgical planning to create a novel
full-coverage surgical splint that allowed for better communication
between the orthodontist and oral surgeon and to enable a better
patient outcome from an increased accuracy of surgical splint and
decreased patient finishing times using clear aligner therapy. ❧
Methods: Immediately prior to surgical workup, braces or clear
aligner therapy attachments are removed if present so that all
surfaces are smooth. The novel full-coverage splint is designed and
manufactured using intraoral scanning of the pre-surgical dentition
and CAD/CAM creation on a 3D printer. Orthognathic surgery is
completed using the full-coverage splint(s) and Maxillomandibular
fixation is applied by means of skeletal anchor screws placed at
the start of surgery. Post-surgery protocol is completed using
clear aligner therapy and the initial clear aligner tray is
delivered 2-3 weeks post surgery. ❧ Discussion: The current golden
standard for orthognathic surgical planning is still utilizing a
plaster model for model surgery and then hand fabricating an
acrylic splint. Only the most forward thinking surgeons are
utilizing the cutting edge technology of virtual surgical planning
and taking CBCT scans of their stone models to have an orthognathic
surgical splint wafer printed. There exist inherent flaws with both
the golden standard and cutting edge methods of splint fabrication.
The advantages of using a full-coverage 3D printed splint are: 1)
Increased accuracy of post-surgical occlusion. 2) Increase in
patient comfort and acceptance of treatment. 3) Accelerated speed
in post surgical orthodontic finishing. ❧ Conclusion: By creating a
more accurate and full-coverage splint, the following was achieved:
1) Operating room time is decreased. 2) Patient outcomes, including
fewer complications and faster rehabilitation, have been improved.
3) Increased surgical precision. 4) Increased communication between
the doctor and patient, including better surgical predictions. 5)
Better communication between the surgeon and referring
orthodontist. 6) Highly predictable surgical results.

▼ Introduction: In today’s orthodontic era, treatment
consists of the use of the same, non-customized prescription
brackets for every individual in a given office. In most instances,
neither prescriptions nor treatment goals are modified to reflect
an individual’s arch form. However, numerous studies on orthodontic
stability have demonstrated the importance in preservation of an
individual’s arch form. Purpose: The objective of the current study
was to determine whether correlations are present between the
mesiodistal angulation and faciolingual inclination of each whole
tooth (crown and root) for various arch forms in three-dimensional
space in a sample of near normal patients. Methods: After
determining a set of inclusion and exclusion criteria, 76
near-normal cases were chosen and digitized utilizing CBCT imaging.
Maxillary and mandibular dental and alveolar bony arches were
digitized; anterior and posterior dental arch width and length and
alveolar bony arch height and length were obtained. Dental arch
width/length (w/l) ratios and alveolar bony arch height/length
(h/l) ratios for the two arches, both anterior and posterior, were
calculated. Correlations between these ratios and the mesiodistal
angulation and faciolingual inclination of each whole tooth were
studied. Results: Pearson and Spearman correlation coefficient
analysis revealed the following results: (1).The mesiodistal
angulation and faciolingual inclination of none of the maxillary
teeth were affected by our arch ratios except for the upper lateral
incisor inclination which demonstrated a negative correlation with
the maxillary anterior alveolar bony arch (h/l) ratio. (2).The
mandibular anterior and posterior dental arch (w/l) ratio did not
affect the angulation or inclination of the mandibular teeth except
that the mandibular posterior dental arch (w/l) ratio demonstrated
a significantly positive correlation with the mesiodistal
angulation of the mandibular first premolar (p

▼ Objective: The Handicapping Labio‐lingual Deviation
Index (HLD) is an orthodontic treatment need index, which is used
to assess the severity of a malocclusion. States such as
California
use the HLD as a screening tool to determine whether patients
qualify for subsidized treatment. The objective of this study was
to compare HLD scores using plaster versus digital models. ❧
Methods: Seventy‐eight duplicate study models that were sent from
Children’s Hospital Los Angeles (CHLA) to Denti‐Cal for evaluation
were scored by an orthodontic fellow (rater 1), a senior
orthodontic resident (rater 2) and by the Denti‐Cal orthodontic
consultant. The scores of a Denti‐Cal consultant were considered
the gold standard in this study. Fifty out of these models were
then scanned using the 3D Ortho Insight laser scanner. Rater 1 and
rater 2 scored the 50 digital models. Kappa statistics were used to
compare inter‐ and intra‐rater reliability. Comparisons included
(a) inter‐rater reliability between plaster model scores of both
raters versus the gold standard, (b) inter‐rater reliability
between rater 1 versus rater 2 for both plaster and digital model
scores and (c) intra‐rater reliability between digital and plaster
model scores for each rater. ❧ Results: Inter‐rater reliability of
Raters 1 and 2 (post‐calibration) versus gold standard was almost
perfect (combined K= 0.89). Inter‐rater reliability of rater 1
versus rater 2 was almost perfect for both plaster and digital
model scores (combined K= 0.85). Intra‐rater reliability was
substantial for both Rater 1 (K= 0.79) and Rater 2 (K = 0.67). ❧
Conclusion: There was substantial intra‐rater agreement between HLD
Cal‐Mod digital and plaster model scores. Differences in HLD
Cal‐Mod scores between digital and plaster models were as high as
13%, and the combined kappa for intra‐rater agreement was 0.73. HLD
specific software is needed to correct the sources of difference in
HLD score. Digital models present a promising alternative to
plaster models for use with the HLD Index. Training and calibrating
raters on proper usage of digital model software and its tools are
recommended, prior to HLD digital scoring.

inclination and angulation by using data purely from CBCT X-rays to
minimize inaccuracies inherent in previous studies based on
traditional X-rays. After determining a set of inclusion and

selected. CBCT X-rays were used to generate 2D lateral
cephalometric head films with minimal amounts of noise and
distortion to maximize accuracy in landmark identification. ANB and
SN-GoGn were chosen to represent antero-posterior and vertical
skeletal parameters, respectively. Data from Kwon’s previous study
on ideal tip/torque values was used to perform correlation studies
with the aforementioned cephalometric parameters. Labial crown
torque for upper incisor, canine, and premolar teeth were found to
be positively correlated with an increase in mandibular plane angle
(p < 0.05). There was no indication of a significant correlation
existing between upper molars and mandibular plane angle.
Mandibular plane angle was not shown to have a significant
correlation with faciolingual inclinations of upper molars or any
lower teeth. ANB shared a negative correlation with the torque of
the maxillary first molar, and a positive correlation with each
lower tooth (p < 0.05). There was a positive correlation between
mesial tip of the lower canine and an increased ANB value (p <
0.05). The clinical implication of this study is the importance in
recognizing that dental and skeletal characteristics are unique to
each individual. Patents should not all be treated in the same
manner with the same objectives. Bracket prescriptions have been
created according to certain patient populations and are not
intended for universal application without modifications. The
orthodontist must focus on the individual needs for each patient
and customize each case through modified bracket positioning or
wire bending as necessary.

Assessment of the knowledge of biostatistics and the
attitude toward evidence based practice among endodontic residents
in the United States: a cross-sectional survey.

▼ Objectives: The objectives of the study were to assess
(1) the knowledge of basic biostatistics among endodontic
residents; (2) the effect of demographic and educational factors on
the level of biostatistical knowledge; (3) the attitude of
endodontic residents towards biostatistics and evidence based
practice. ❧ Materials and methods: An anonymous electronic survey
was distributed among currently enrolled endodontic residents
nationwide. The survey instrument included three main sections:
demographic and educational background, confidence and attitude,
and a multiple choice question test on selected basic statistical
concepts. ❧ Results: A total of 134 responses were analyzed with
response rate (RR1) of 27.7%. The percentage of overall mean
correct answers was 51.3% (SD: 17.3%). The majority of the
participants (66%) thought that biostatistical knowledge is
important for evidence-based practice. However, only 20% had high
confidence in understanding statistical methods used in endodontic
literature. The overall mean score for the biostatistics knowledge
test was 51.3% (SD, 17.2; range, 22.2-88.9). Participants who were
younger than 30 years of age and those who had statistical
education during residency were more likely to have higher mean
score. ❧ Conclusion: We found an overall limited knowledge in
biostatistics among endodontic residents. Participants with recent
statistical education demonstrated slightly favorable knowledge
regardless of their gender, level of previous statistical
education, academic degree, or having previous scientific
publications.
