Full textObjective: According to the divergences of informations in the evaluation of the masticatory function as for the investigated aspects and the form of evaluation of them, as well as the need of standardization for comparison of the patients' masticatory function; it was necessary to elaborate a proposal of clinical evaluation of the masticatory function. Material and Method: A questionnaire was elaborated and sent by e-mail for some Speech Pathologists from several places from Brazil. This questionnaire had some questions about the formation and the professionals' performance and informations about the aspects that were investigated in the clinical history of the masticatory function and in the evaluation of this function as for the morphologic and functional aspects that were investigated and the form of evaluation of the masticatory function, besides the verification of other oral functions. Seventy questionnaires were answered and analyzed and they were used for the elaboration of the proposal of evaluation besides the analysis of the literature and experience of the Speech Pathologists of the Laboratory of Physiology at HRAC/USP. Results: From the analyses it was proposed the elaboration of a protocol of evaluation of the masticatory function, contemplating the following aspects: the test foods, the amount of the test foods, the teeth that bite the food, the mandibular movement, the initial side of the masticatory function, the masticatory laterality, the participation of the perioral muscles, the labial posture, if exists tremor, the contraction of muscles masseteres, the coordination of the mandibular movements, if there is a leak of food from the mouth, the trituration of the food with the tongue, the head's movement, the place of the trituration of the food, the breathing during the mastication, the noises in ATMs, the duration of masticatory function, the number of masticatory cycles, the formation of the bolus, if there is cough or choking and pain during the mastication, besides the test of masticatory efficiency. Final considerations: It was verified the lack of standardization of the evaluation of the masticatory function related to the aspects to be investigated, as well as the form of evaluation of them. For this reason, this work proposes a protocol for the clinical evaluation of the mastication and it will contribute with the Speech Pathology to bring criteria for the evaluation of the masticatory function.

Patients with cerebral palsy are faced with motor limitations in chewing, swallowing and speech. It is essential to understand their oral motor function to guide the diagnosis and treatment. Surface electromyography is a diagnostic tool for clinical evaluation of muscle activity. This study aimed to evaluate the clinical and electromyographic behavior of oral motor function in adult patients with cerebral palsy. 30 patients with cerebral palsy, both gender, aged between 19 and 59 years were enrolled in this study. After anamnesis and clinical examination, oral motor function was assessed through a scale that evaluated: jaw, tongue, lips, soft palate and larynx mobility, as well as facial expressions. The score achieved by each patient according to her/his performance in accomplishing oral movements classified her/his impairment of oral motor function in mild, moderate and severe. Surface electromyography was recorded bilaterally from masseter, anterior temporalis and suprahyoid muscles at rest, isometry and openness position. A force transducer and a goniometer were used to measure, respectively, maximum bite force and opening. Finally, the compatibility between the clinical and electromyographic evaluation was statistically assessed by means of Friedman, Mann- Whitney and Wilcoxon test. The degree of oral motor impairment was mild in 60% of the patients, severe in 36.66% and mild in 3.33%.

O presente trabalho teve por objetivo avaliar o reposicionamento mandibular em pacientes assintomáticos e pacientes com sintomatologia dolorosa dos músculos mastigatórios. Com esta finalidade, foi utilizada uma amostra de 24 pacientes, divididos em 2 grupos (I e II). Para o grupo de casos (I), foram selecionados de forma aleatória 12 pacientes do sexo feminino, todos sintomáticos, totalmente dentados. Para o grupo controle (II), indivíduos do sexo feminino totalmente dentados, sem sinais e sintomas de desordem do sistema mastigatório. Para verificar o reposicionamento, após os modelos montados em máxima intercuspidação habitual (MIH) no articulador semi-ajustável, confeccionamos para cada paciente uma plataforma de registro, uma pua, um JIG de Lucia e uma placa oclusal miorrelaxante (POMR).Na plataforma de registro, realizaram-se marcações após o uso do Jig por quinze minutos e a POMR por sete e quinze dias , tendo como ponto de referência a MIH do Paciente. O que pode ser observado foi que o JIG por 15 minutos conseguiu promover um deslocamento mandibular posterior, igual ao uso da placa oclusal miorrelaxante por sete e quinze dias nos dois grupos. A média de deslocamento para o grupo I foi de 1,28mm (s=1.5), para o grupo II a média foi de 0.4mm (s=0.7), nível de significância de 95%.. Os resultados permitem concluir que não houve diferença significativa no reposicionamento final observado após o uso do JIG e da PMOR.
The focus of this study was to mensure the jaw replacement in assymptomatic pacient and pacient with masticatory muscles pain symptomatology. A sample composede of twenty four patients were divided in two groups I and II. The case group(I), was composed by twelve symptomatic, fully teeth , females individuals.The control group (II), was composed by twelve non symptomatic, fully teeth, females individuals. To check the jaw replacement, the cast was mounted on semi-adjustable articulator. Over the cast mounted were manufactured a horizontal plataform , a device worked, a jig of Lucia and a splint. The displacement of the position mandible after the use of the Jig (during 15 minutes) and after the used of splint ( 24 h/ day controlled 15 days). The distances between the marks were measured in a microscopy and the results were statistically analized. The use of the Jig( during 15 minutes), was able to reposit the jaw as the splint( 24 h/ day contolled 15 days) in both group. The replacement average to the group I was 1.28mm and for group II was 0.40mm. The result suggests that jaw replacement after using the Jig and the splint on the two group present similar behavior.

Full textThe stomatognathic system is a set of oral structures, organs and tissues that develop common functions, interdependent, and as a fundamental characteristic for the morphologic and functional development, especially the chewing, two important factors: the development and craniofacial muscle. Like any system, has features of its own, but is closely linked to the function of other systems like the nervous, circulatory, endocrine, and everyone in general because it is a separate unit from the rest of the body, but integrates the him. Several studies about the growth of the facial skeleton, however, little is known about the development of the muscular system of the head, in view of the difficulty associated mainly with methods of study. The muscles are developed, morphologically and functionally, in a planned and organized, but there are still many doubts and questions how that occur, particularly during the aging of the human being. This paper seeks evidence of muscle interaction in craniofacial development over the years and aims to analyze the electromyographic activity of masseter and temporal muscles of children, youth, adults and seniors, aiming to draw up criteria and parameters that can be considered normal in masticatory muscle development in relation to age and gender. The study focused aim to facilitate diagnostic and prognostic, bringing contributions to the quality and stability of treatments, as well as establishing patterns of normality.

Full textFibromyalgia syndrome is characterized by chronic and diffuse muscle pain in at least eleven points of the human body (tender points), morning stiffness, fatigue, sleep disturbances, extensive pain symptoms in the face, which is mainly manifested in the masticatory muscles, temporomandibular joint and ear region. The aim of this study was to analyze the masticatory (masseter and temporal) and cervical (sternocleidomastoid and trapezius) muscles in women with diagnosis of fibromyalgia syndrome. Sixty-eight women aged between 40 and 60 years participated in this research. They were divided into two distinct groups: FG: fibromyalgia syndrome (n = 34) and CG: healthy control (n = 34). The Myosystem-Br1 electromyography was used to analyze the EMG activity. The thicknesses of the masticatory and neck muscles were acquired by ultrasound Sonosite Titan. The maximum molar bite force was obtained using a digital force gauge Kratos. The data of EMG activity, muscles thickness and maximal molar bite force were tabulated, standardized and subjected to statistical analysis (SPSS 21.0). There were statistically significant differences (p<= 0.05) between FG and CG at all mandibular postural conditions, chewing, muscle thickness and molar bite force, with lower average data for FG. Based on the results of this research, the authors concluded that women with fibromyalgia syndrome have alterations in the stomatognathic system

The aim of the study was to investigate whether children with cleft lip and palate (CLP) have altered control of masticatory muscles. The muscular activity of 66 children with CLP (n=33) and without CLP (n=33), aged between six and 12 years was assessed during different tasks (rest, isometric, mastication) using electromyography. Amplitude of Muscle Activation (AMA) of the analyzed muscles was higher in children with CLP at rest (R) and inactive period (IP) (p <0.05), since the active period (AP) and isometric (I) was higher in children without CLP (p <0.05), except for the right masseter muscle in AP, which although less activation did not obtain significant results. Also found that the muscles of children with CLP remained active for longer than those without CLP (p <0.05) and length of the masticatory cycle was higher in children with CLP (p <0.05). The muscles of children with CLP in the R and IP of mastication are superior when compared to the control group. Already during the AP and I are reduced activation. Children with CLP have longer muscle activation during the chewing cycle and increased cycle time, which probably influences the occlusion, resulting in greater difficulty in chewing.
O objetivo do estudo foi investigar se crianças com fissura labiopalatal transforame incisivo unilateral (FLPU) possuem alterações no controle da musculatura mastigatória. A atividade muscular de 66 crianças sem fissura (n= 33) e com FLPU (n= 33), entre seis e 12 anos foi avaliada durante diferentes tarefas (repouso, isometria e mastigação) utilizando eletromiografia. A Amplitude de Ativação Muscular (AAM) dos músculos analisados foi maior nas crianças com FLPU no período de repouso (R) e período inativo (PI) (p <0,05). Já no período ativo (PA) e isometria (I) foi maior nas crianças sem FLP (p <0,05), com exceção do músculo masseter direito no PA, que apesar de menor ativação não obteve resultados significativos. Observou-se que os músculos das crianças com FLPU permaneceram ativos por mais tempo (p <0,05) e a duração do ciclo mastigatório foi superior nas crianças com FLPU (p <0,05). A atividade muscular da criança com FLPU no R e PI da mastigação é superior quando comparado ao grupo controle. Já durante o PA e I a ativação muscular é reduzida. Crianças com FLPU apresentam maior tempo de ativação muscular durante o ciclo mastigatório e maior duração do ciclo, o que provavelmente influência na oclusão, resultando em maior dificuldade na mastigação.

Full textThe definition of reference values of healthy subjects is a fundamental parameter for the diagnosis in health. The aims of this study were to establish reference values based on standardized score for the orofacial myofunctional condition, for the orofacial strength and for the masticatory efficiency, and to analyze the relationships between them, after establishing a performance index for orofacial strength and masticatory efficiency. From a total of 316 subjects, 50 participants were selected, 21 men and 29 women, ranging from 18 to 40 years old, without temporomandibular disorder, no orofacial myofunctional disorder and presenting normal occlusion. Subjects were assessed using the Orofacial Myofunctional Evaluation Protocol with Scores (OMES) to investigate the orofacial myofunctional condition. The orofacial strength evaluated were maximal isometric bite forces on the right and left sides, maximal isometric cheeks strength on the right and left sides, maximal isometric tongue strength on the anterior and dorsum region and maximal isometric lips strength using an electronic dynamometer Kratos®. The values were recorded in Newton (N). The mean value of three trials of each orofacial strength was obtained. The masticatory efficiency was analyzed by colorimetric method with beads. The fuchsine concentration in micrograms per milliliter (µg/ml) was obtained. The masticatory efficiency was evaluated in three conditions: habitual, right and left unilateral chewing, for 20 seconds each one. For all variables, the Z scores were calculated to determine the reference values and cutoff values that differentiate the normal and abnormal subjects. The orofacial strength and masticatory efficiency values were transformed into the performance index, for 34 participants that were defined as normal subjects. The random error was calculated for all variables. Statistical analysis was performed using Spearman correlation test, using the MedCalc® program and the level of significance was p<0.05. The reference values (mean and standard deviation), established from the Z score, were 95.79 ± 3.74 for the orofacial myofunctional condition; 431.08 ± 138.01N for the maximal isometric bite force; 17.92 ± 7.44N for the maximal isometric cheeks strength; 9.45 ± 4.01N for the maximal isometric tongue strength in the anterior region; 13.44 ± 5.46N for the maximal isometric tongue strength in the dorsum region; 4.31 ± 1.48N for the maximal isometric lips strength; 0.72 ± 0.31µg/ml for the habitual masticatory efficiency; 0.71 ± 0.30µg/ml for the right masticatory efficiency, 0.78 ± 0.37µg/ml for the left masticatory efficiency. No correlations were found neither between the orofacial strength performance index and masticatory efficiency performance index (r=0.102, p>0.05), the orofacial strength performance index and orofacial myofunctional condition (r=-0.005, p>0.05), nor between the masticatory efficiency performance index and orofacial myofunctional condition (r=0.059, p>0.05). There was no relationship between the biomechanics orofacial and masticatory efficiency in this study.
