“…It should be highlighted that no study has employed the anamnesis questionnaire used in this study, yet included clinical examination of the TMJ, visual analogue scale, anamnesis index and of dysfunction of Helkimo (21) , or applied the RDC/TMD protocol (22) . The MBF was reduced in individuals with DFD compared to CG, in agreement with reports in the literature (5,6,13,14,15) . It should be considered that dentofacial deformities cause Subtitle: GDFD = group with dentofacial deformity; CG = control group important changes in the physiology of the masticatory system, especially during presurgical orthodontic treatment, when there is worsening of occlusion, with loss of the physiological adjustments acquired along the lifetime (14) .…”

“…Different authors observed predominance of signs and symptoms of TMD in individuals with DFD during presurgical orthodontic treatment compared to a control group (10,11,12) . The literature demonstrates reduced bite force values in individuals with DFD during presurgical orthodontic treatment, compared to a control group with normal occlusion and absence of signs and symptoms of TMD (5,13,14,15) . The relationship between pain and dynamic bite force control in individuals with DFD is not yet clear, since there is no consensus on how this dysfunction influences this aspect.…”

Introduction: Individuals with dentofacial deformity (DFD) show impairment in dental occlusion, which may alter the masticatory performance and, consequently, the bite force. No research was found on the relationship between temporomandibular disorders (TMD) and bite force for this population. Purpose: To determine if the presence of TMD symptoms influence the maximum bite force (MBF) in individuals with DFD. Methods: Sixty individuals were evaluated, 30 with DFD (GDFD) and 30 with normal occlusion (CG). The TMD was assessed by an anamnesis questionnaire (AQ) containing 10 questions that allow classification of the presence and degree of signs and symptoms of TMD. MBF was assessed using a mandibular force sensor, of the EMG System 810c electromyograph. Three records of bite force were obtained, with 10-second duration each. The Spearman correlation coefficient was used, at a significance level of 5%. Results: The results of AQ showed higher prevalence of TMD symptoms in GDFD in relation to CG. Also, lower MBF was observed in subjects with DFD compared to CG. In addition, negative and significant correlations were found between scores obtained in the application of AQ and the MBF; therefore, the higher the severity of TMD symptoms, the lower the bite force. Conclusion: The presence and severity of TMD symptoms influenced the MBF in individuals with DFD, demonstrating the importance for interdisciplinary intervention during all stages of surgical-orthodontic treatment.

“…Since spontaneous correction is rare [2], it is believed that the PC is transferred to the permanent dentition, with long-term effects on the growth and development of the stomatognathic system. According to Nakata et al [3], individuals with this type of malocclusion may show qualitative differences in the functioning of the masticatory muscles, when compared with individuals without malocclusion, since it represents deformity in the bone bases or occlusal problems.…”

“…There are also studies that indicate that the temporal muscle is more active than the masseter not only during dental clenching, but also during mastication (13) . Due to the presence of bone deformities and occlusal problems, a qualitative difference in the functioning of the masticatory muscles is expected In individuals with skeletal malocclusion compared with individuals without malocclusion (14) . The presence of posterior crossbites indicates a higher likelihood of masticatory changes (14) .…”

The presence of posterior crossbites indicates a higher likelihood of masticatory changes (14) . Studies involving patients with different types of dentofacial deformities indicate a low performance of the masticatory muscles, reduced maximal force of contraction, reduced maximal potential recorded during the sEMG and reduced electrical potentials recorded during mastication, compared to control groups (14,15) .…”

OBJETIVO: Caracterizar o controle motor dos músculos masseter e temporal e a morfologia do músculo masseter em atividades da função mastigatória em indivíduos com oclusão normal; verificar a compatibilidade entre os exames de eletromiografia de superfície (EMGs) e ultrassonografia (USG). MÉTODOS: Participaram 22 indivíduos adultos, de ambos os gêneros, sem alterações no sistema miofuncional orofacial. Os procedimentos adotados para avaliação dos participantes foram: EMGs dos músculos masseteres (MM) e temporais (MT); e USG dos MM, na realização de três tarefas - repouso muscular, apertamento dentário com algodão, apertamento dentário sem algodão. RESULTADOS: Para análise estatística dos dados foram utilizados os testes de Kolmogorv-Smirnov, teste-T pareado e Correlação de Spearman, com nível de significância de 5%. Na EMGs observou-se diferença entre a ativação de MM e MT no apertamento dentário com e sem algodão, sendo MT mais ativo que MM em ambas as tarefas. Não foram observadas diferenças entre as hemifaces, tanto na EMGs quanto na USG. Observou-se também correlação positiva entre os exames na condição de apertamento dentário sem algodão esquerdo e na condição de apertamento dentário esquerdo com algodão, e tendência à significância no apertamento dentário direito sem algodão. CONCLUSÃO: A associação da EMGs e USG na investigação da funcionalidade muscular traz importantes informações sobre fisiologia da musculatura esquelética. Os resultados do presente estudo indicam haver correlação entre a EMGs e a USG, ou seja, o aumento da atividade elétrica e o aumento correspondente da espessura do músculo.
