Falhas na adaptaÃÃo entre o implante e o pilar protÃtico provocam uma fenda que tanto propicia a proliferaÃÃo microbiana e doenÃas peri-implantares como facilita a ocorrÃncia de fraturas das prÃteses e seus componentes. Neste estudo avaliaram-se a qualidade e a precisÃo da interface implante/conector protÃtico de implantes endoÃsseos de 2 estÃgios cirÃrgicos, por meio de uma avaliaÃÃo microbiolÃgica in vitro e de mensuraÃÃo da desadaptaÃÃo atravÃs de microscopia eletrÃnica de varredura. Foram utilizados 30 implantes, divididos em 3 grupos de 10 unidades (n=10), sendo denominados G1, G2 e G3 os implantes de hexÃgono externo, interno e externo com torque interno respectivamente. ApÃs manipulaÃÃo dos implantes em cÃmara de fluxo laminar, inoculou-se 0,3 Âl de uma soluÃÃo contendo colÃnia da bactÃria Streptococcus sanguis ATCC 10556 na cavidade da rosca interna de cada implante, sendo o conector protÃtico adaptado e parafusado com o auxÃlio de um torquÃmetro atÃ que se atingisse 30 N/cm. Cada conjunto foi colocado em meio de cultura BHI (Brain Heart Infusion), mantidos sob condiÃÃes ideais durante 14 dias em estufa bacteriolÃgica, verificando a cada 24 horas a presenÃa de contaminaÃÃo visÃvel. Depois de cumprida essa etapa cada conjunto foi analisado ao microscÃpio, mensurando-se os espaÃos existentes na desadaptaÃÃo vertical (eixo Y) e da falta de adaptaÃÃo marginal (eixo X) com aumento de 20 a 2000 X. Observou-se que todos os grupos apresentaram microinfiltraÃÃo bacteriana, sendo o G2 o que apresentou menor Ãndice de contaminaÃÃo com 70%, ocorrido em mÃdia em 4,1 dias, seguido pelo G1 com 90% em 2,4 dias e do G3 com 100% em 1,2 dias. Verificou-se que os implantes/conectores protÃticos de hexÃgono interno possuem uma melhor adaptaÃÃo dentre os sistemas avaliados, provocando menor microinfiltraÃÃo bacteriana. Quanto Ã microscopia, o G2 apresentou menor desadaptaÃÃo vertical com mÃdia de 1,90Âm, o G3 obteve mÃdia de 2,60Âm e mÃdia de 2,72Âm para o G1. Na adaptaÃÃo marginal o G1 obteve melhor resultado, apresentando uma falha mÃdia de 9,12Âm, seguido pelo G3 com mÃdia de 10,80Âm e do G2 com mÃdia de 12,45. Os resultados foram submetidos a testes estatÃsticos de Kruskal- Wallis com nÃvel de significÃncia de 5% para comparaÃÃo entre os implantes de cada grupo, nÃo havendo diferenÃas entre os grupos. TambÃm foi testada a correlaÃÃo entre a desadaptaÃÃo vertical e o perÃodo de contaminaÃÃo por meio do teste de correlaÃÃo de Spearman, verificando uma acentuada correlaÃÃo. Concluiu-se que as desadaptaÃÃes verticais e marginais encontram-se dentro de um padrÃo de qualidade aceitÃvel, independente do tipo de implante, ainda que os nÃveis de contaminaÃÃo bacteriana tenham sido bastante elevados, fato que estÃ diretamente correlacionado com a desadaptaÃÃo na interface implante/conector protÃtico.

O objetivo deste estudo foi avaliar in vitro a capacidade seladora de alguns materiais odontológicos em retrobturações e para tanto, utilizou-se o MTA Ângelus® Branco, MBPc, CPM® e Pasta Lysanda®, através da análise da infiltração do Enterococcus faecalis. Noventa dentes humanos unirradiculares extraídos e instrumentados, tiveram seu ápice radicular cortado num plano perpendicular ao longo eixo onde foram preparadas cavidades retrógradas com 3mm de profundidade, para selamento com os materiais em teste já relacionados. Culturas específicas de Enterococcus faecalis foram preparadas e inoculadas nos condutos radiculares dos dentes previamente fixados em aparatos especiais que tinham do lado oposto um meio de cultura estéril e específico para a bactéria em questão, separados apenas pelas retrobturações dos grupos de materiais em teste. Diariamente, o meio estéril era checado para constatar sua possível turvação; caso ocorresse demonstrava a passagem bacteriana pela retrobturação. Os quatro grupos experimentais apresentaram ao menos um espécime com infiltração bacteriana logo nas primeiras 24 horas do teste, entretanto, o número de espécimes que apresentavam turvação foi diminuindo numericamente no decorrer do período experimental, que foi de 120 dias. Os cimentos MTA Ângelus® Branco, MBPc e CPM® mostraram capacidade seladora eficaz e também comportamento semelhante entre si, pois a turvação das poucas amostras ocorreu logo nos três primeiros dias. A pasta Lysanda® apresentou o maior número de amostras infiltradas (18), em maior período de tempo.

The objective of this study was to in vitro evaluate the sealing ability of some dental retrofilling material and for that, we used the White MTA Angelus®, MBPc, CPM® cements and Lysande® paste, by examining Enterococcus faecalis infiltration. Ninety human extracted single-rooted teeth were instrumented, had their apex cut perpendicular to the long axis where the retrograde cavities were prepared with 3 mm deep, sealed with the retrofilling materials used on the study. Specific cultures of Enterococcus faecalis were prepared and inoculated into the teeths root canals previously fixed in special apparatuses that had in their opposite side a sterile type of culture specific for the bacteria in question, separated only by the retrofilling materials under test. Daily, the sterile culture was checked to verify their possible turbidity; and when there was, it demonstrated the bacterials passage by the retrofilling material. All experimental groups showed at least one specimen with bacterial infiltration in the very first 24 hour testing, however, the number of specimens that showed turbidity had decreased numerically during the trial period of 120 days. White Angelus MTA®, CPM® and MBPC cements showed effective sealing capacity and also similar behavior among themselves, because the turbidity of the few samples occurred just in the first three days. Lysanda® paste presented the greatest number of samples infiltrated (18), in a greater period of time.

Pathogenic microorganisms and heavy metals have frequently been detected in urban stormwater runoff. Pathogens transport to the groundwater table with the infiltrating water and cause groundwater contamination. A variety of physical, chemical and biological factors have been studied for their effects on bacterial transport. However, the effect of heavy metals has largely been ignored, despite the elevated concentrations common in stormwater runoff. This work examines changes in bacterial and soil surfaces using scanning electron microscopy and energy dispersive X-ray spectroscopy after exposure to synthetic stormwater amended with heavy metals. Sets of batch bacterial sorption experiments were conducted under different conditions by varying heavy metal concentrations in synthetic stormwater and soil exposure history. The results indicate that the presence of heavy metals increases bacterial attachment to soil surfaces.Modeling bacterial transport during stormwater infiltration is challenging due to the variability and complexity of the physical, chemical and biological interactions in the soil-water-bacteria system. This work quantified changes in bacterial attachment under variable solution chemistry using a newly combined rate equation, which varies temporally and spatially with changes in solution chemistry. The relative importance of physiochemical variation on the estimation of bacterial attachment was quantitatively described using two-phase Monte Carlo analysis. A semi-reactive microbial transport model was further developed in HP1 (HYDRUS1D-PHREEQC) with the incorporation of the newly combined rate equation. The model matched observed bacterial breakthrough curves in laboratory column experiments well. This method represents one step towards a more realistic model of bacterial transport in complex microbial-water-soil systems.The developed model was further applied to the investigation of bacterial removal in field bioretention systems. The influent and effluent water samples from bioretention systems in New York City were sampled and analyzed over the summer of 2012 for fecal indicator Escherichia coli. Reduction of the effluent bacterial concentrations was observed and the removal efficiency was up to 66%. The antecedent dry period was found to affect bacterial removal. Shorter antecedent dry period results in higher soil moisture which is favorable for bacteria in soil to persist. The semi-reactive microbial transport model was applied and the modeled bacterial removal efficiency agrees well with observed values with a slight overestimation. This is primarily due to the presence of preferential flow paths in the field bioretention systems, which are not considered in the model.

▼ The shallow bar built, well flushed Avon-Heathcote Estuary is a popular recreational area. Water quality within the Estuary is reduced by inputs of enteric organisms, which may include pathogens, originating from the Avon and Heathcote Rivers, oxidation pond effluent (Christchurch Treatment Works), wildlife, recreational water users and runoff from the surrounding catchment. The sediments of estuaries have been shown to be a reservoir of bacteria of sanitary significance and so a study was undertaken to determine the importance of sediment in the Estuary. Counts of faecal coliforms in sediment deposited at two intertidal sites during one tidal cycle ranged from 30 to 556 g⁻¹ (dry weight) and numbers appeared to be influenced by factors including turbulence and sediment type. Experiments undertaken to determine the role of adsorption in the removal of faecal coli forms from the water column suggested that much higher densities than would normally be expected would be needed in the water overlying one intertidal site to explain the observed counts unless other mechanisms were involved in the removal of faecal coliforms from the water column. Movement of faecal coli forms through sediment packed into columns was studied after an in situ experiment suggested that faecal coli forms deposited onto surface sediment could move to deeper sediment. Experiments showed that sediment profiles appeared to retain relatively high proportions of the faecal coli forms applied to them. Enumeration of faecal coli forms in sections taken from sediment profiles showed that numbers of faecal coli forms retained in the sediment declined approximately logarithmically with depth. When sediment profiles containing high numbers of faecal coliforms were flushed with water of low conductivity relatively few faecal coliforms were removed from the sediment. Enumeration of faecal coliforms in sections taken from sediment profiles suggested that faecal coliforms removed from the surface could be retained further down sediment profiles. A second in situ experiment suggested that bacteria could potentially travel far below the surface layers of sediment if they remained suspended in percolating estuarine water. A combination of gentle physical disturbance and reduction in the salinity (conductivity) of estuarine sediment-water mixtures resulted in substantial release of sediment bound faecal coliforms. Sediment was demonstrated to extend the survival of faecal coliforms when estuarine water and sediment were incubated together at 15°C in the dark. This appeared to be substantiated by faecal coliform counts in sediment at an intertidal site which were higher than those in the overlying water according to a previous bacteriological survey. Counts also varied seasonally while higher numbers of faecal coli forms were found in the 0-10 mm depth than at the 10-40 mm depth of sample cores. The findings of this study appear to substantiate the belief that estuarine sediments can be reservoirs of bacteria of sanitary significance, therefore,…
