Abstract
Purpose: to study the relationship of thickness and electrical activity of the masseter muscle with the bite force.
Methods: the study included 17 young adults (21.3 ± 1.4 years), 7 female and 10 male, healthy and clinically asymptomatic, as temporomandibular disorders. It was performed to measure the thickness of the masseter muscle unilaterally during rest and maximal voluntary contraction. It was also quantified the bite force for each side with a force transducer positioned in the first molar region and simultaneously, it was assessed the electrical activity of the masseter muscle during the unilateral bite. The analysis was based on the comparison of samples, and used the t test, Wilcoxon, Mann-Whitney and multivariate linear regression.
Results: the thickness of the masseter muscle was greater in men than in women, both at rest and in contraction. We found symmetry between the sides with the muscles at rest and during contraction. The median frequency of the electromyographic signal to the masseter muscle in maximal voluntary contraction, showed no statistically significant difference intra-individuals and the comparison between the genres. We found a higher bite force in males. It was not found a multivariate linear regression model between variables.
Conclusion: in this study, it was not possible find a linear model with the variables studied.

Resumo
Objetivo: estudar a relação da espessura e da atividade elétrica do músculo masseter com a força de mordida.
Métodos: participaram do estudo 17 adultos jovens (21,3 ± 1,4 anos), sendo 7 do gênero feminino e 10 do gênero masculino, saudáveis e clinicamente assintomáticos, quanto a disfunções temporomandibulares. Foi efetuada a medida da espessura do músculo masseter unilateralmente, durante o repouso e contração voluntária máxima. Também foi quantificada a força de mordida para cada lado com um transdutor de força posicionado na região do primeiro molar e simultaneamente avaliou-se atividade elétrica do masseter durante a mordida unilateral. A análise foi baseada na comparação das amostras, sendo utilizados o test t, Wilcoxon, Mann-Whitney e regressão linear multivariada.
Resultados: a espessura do músculo masseter foi maior nos homens, tanto no repouso quanto em contração. Observou-se uma simetria entre os lados com os músculos em repouso e em contração. A frequência mediana do sinal eletromiográfico, para o músculo masseter em contração voluntária máxima, não apresentou diferença estatisticamente significante intra-indivíduos e na comparação entre os gêneros. Foi encontrada maior força de mordida nos indivíduos do gênero masculino. Não foi encontrado um modelo de regressão linear multivariada entre as variáveis estudadas.
Conclusão: neste estudo, não foi possível encontrar um modelo linear com as variáveis estudadas.
