1. 鈴木, 峻一. Blood oxygenation of masseter muscle during sustained elevated muscle activity in healthy participants : 持続的なヒト閉口筋随意収縮時の筋内血液酸素動態.

Degree: 博士(歯学), 2017, Hokkaido University / 北海道大学

Myofascial pain associated with temporomandibular disorders has often been linked to pathological muscle hyperactivity. As a result, localised disturbances of intramuscular blood flow could lead to a lower level of oxygen distribution, hypoxia and microcirculatory changes. To assess haemodynamic changes in the masseter muscle during sustained elevated muscle activity (SEMA). Sixteen healthy participants performed thirty 1-min bouts of SEMA with intervals of 1-min ‘rest’ periods between the bouts on a bite force transducer device. The participants completed three sessions with different percentage of their maximal voluntary occlusal bite force (MVOBF): 0% (no task), 10% or 40% MVOBF tasks. The order of the sessions was randomised with 1- to 2-week intervals. Haemodynamic characteristics of the masseter muscle were estimated with use of a laser blood oxygenation monitor. Tissue blood oxygen saturation (StO2) during SEMA was lower than during rest (P < 0·001). The relative changes in total haemoglobin (Total-Hb) and StO2 were influenced by condition (SEMA and rest) and with interactions between condition and session (0%, 10% and 40% MVOBF tasks). These results suggest that SEMA may lead to hypoxia in the masseter muscle and that the haemodynamic characteristics and muscle symptoms depend on the magnitude of muscle contractions. Overall, the present findings may help to provide better insights into relationships between jaw muscle activity, haemodynamic changes and symptom developments with implications for clinical conditions such as bruxism characterised by different levels of tooth-grinding and tooth-clenching muscle activity.

2. Rosa, Lâner Botrel. Efeito da perda dental na atividade eletromiográfica da musculatura da mastigação e na força de mordida máxima.

Degree: Mestrado, Reabilitação Oral, 2007, University of São Paulo

A perda dental promove alterações no sistema mastigatório, que podem afetar a parte óssea, a mucosa bucal e o controle muscular. O objetivo deste trabalho foi verificar a força de mordida máxima, a atividade eletromiográfica em diversas situações clínicas e a força de mordida máxima correlacionada com atividade eletromiográfica em 28 indivíduos, sendo 14 parcialmente desdentados e 14 indivíduos dentados. A eletromiografia foi realizada com o Myosystem-Br1, com os eletrodos posicionados nos músculos masseter e temporal, direito e esquerdo e um eletrodo de referência no osso frontal. Os registros da força de mordida foram realizados após os testes eletromiográficos utilizando um dinamômetro com capacidade até 100Kgf, adaptado às condições bucais. O maior valor entre três registros executados foi considerado a força máxima da mordida do indivíduo. Realizou-se a análise estatística dos dados eletromiográficos por meio do teste t com o programa SPSS 12.0. Para a análise entre força de mordida e atividade eletromiográfica foi utilizado o teste de correlação bivariada de Pearson. Verificou-se que a atividade eletromiográfica dos músculos masseter e temporal nos indivíduos parcialmente desdentados foi maior nas condições clínicas de repouso, apertamento dental com algodão, protrusão e lateralidade esquerda. A força de mordida máxima foi maior nos indivíduos dentados nas três regiões. As correlações entre a atividade eletromiográfica e a força de mordida do grupo dentado obtiveram coeficientes positivos para todos os músculos na região molar direita, para o músculo temporal esquerdo na região molar esquerda e para todos os músculos na região incisiva. Para o grupo desdentado parcial somente o músculo temporal esquerdo apresentou correlação positiva na região molar direita. A correlação foi positiva para os músculos masseter direito e temporais, direito e esquerdo na região molar esquerda e, na região incisiva todos os músculos apresentaram correlação negativa. Estes dados evidenciam a grande influência da ausência dental na função do sistema mastigatório.

Dental loss poses changes in the masticatory system, which can affect the boney aspect, oral mucosa, and muscular control. The purpose of this study is to verify the following items in 28 individuals: maximal bite force; electromyographic activity at rest and at maximal voluntary contraction (MVC); dental clenching with cotton; right and left laterality; protrusion; and maximal bite force correlated with electromyographic activity. Participants were 14 partially edentulous and 14 dentate individuals. Electromyography was performed using Myosystem-Br1 with electrodes positioned on right and left masseter and temporalis muscles, and one reference electrode on the frontal bone. Bite force was registered after the electromyographic tests using dynamometer with capacity of up to 100Kgf, adapted for oral conditions. The highest value out of three recordings was considered the individual\'s maximal bite force. Statistical analysis of the electromyographic data was performed…
