Temporomandibular joint dysfunction and anxiety in graduate dentistry

As Desordens Temporomandibulares são doenças que afetam as articulações temporomandibulares e músculos da mastigação do aparelho estomatognático. Fatores psicossociais desempenham papel importante na etiopatogenia dessa doença. O objetivo deste estudo é avaliar a relação entre o grau de desordem temporomandibular e o nível de ansiedade em estudantes de graduação em Odontologia, em três períodos do curso (1o ao 4o semestres, 5o ao 7o, e 8o ao 10o semestres), por meio dos questionários auto-aplicáveis Índice Anamnésico de Fonseca e do Inventário de Ansiedade Traço-Estado (IDATE). Os dados foram tabulados e posteriormente analisados por meio dos testes estatísticos Kruskal-Wallis e correlação de Pearson, ao nível de significância de 1%. Os resultados mostraram correlação positiva e diferença estatisticamente significante entre DTM e ansiedade, em todos os períodos avaliados; e um nível mais alto de ansiedade foi observado no período intermediário do curso (5o ao 7o semestres). Concluímos que houve relação diretamente proporcional entre DTM e ansiedade nos alunos avaliados, estatisticamente significante, independente do estágio cursado; o maior nível de ansiedade foi observado no grupo formado por alunos do 5o ao 7o semestres, contudo sem nenhuma significância estatística. Torna-se importante desenvolver uma estratégia para o controle do estresse e da ansiedade dos alunos no curso de graduação em Odontologia. _________________________________________________________________________________ ABSTRACTThe Craniomandibular disorders are illnesses that affect the joints temporomandibulares and muscles of the chew. Psycho-logical and social factors are important role in the etiology of this illness. The objective of this study is to evaluate the relation between the degree of craniomandibular disorders and the level of anxiety in students of graduation in Dentistry, in three periods of the course, by means of the auto-applicable questionnaires Fonseca’s Index and of the State Trait Anxiety Inventory (STAI). The data had been tabulated and analyzed by means of the statistical tests Kruskal-Wallis and correlation of Pearson, to the level of signifcance of 1%. The results had shown to positive correlation and statistically signifcant difference between craniomandibular disorders and anxiety, in all the evaluated periods; e a higher level of anxiety was observed in the intermediate period of the course (5o to 7o semesters). We conclude that it had directly proportional relation between craniomandibular disorders and anxiety in the evaluated students, statistically signifcant, independent of the attended a course period of training; the biggest level of anxiety was observed in the group formed for students of 5o to 7o semesters, however without no signifcance statistics; and is important to develop a strategy for the control of stress it and the anxiety of the pupils in the course of graduation in Dentistry

Factors associated to the occurrence of joint sounds

Objetivou-se neste trabalho verificar a associação do sexo, classe econômica, qualidade do sono e estresse com a ocorrência de vibrações articulares. A população deste estudo constituiu-se inicialmente por 160 indivíduos de ambos os sexos do município de Piacatu, São Paulo, Brasil, nos quais aplicou-se o Questionário de Fonseca, para verificar o grau de DTM. Posteriormente, os indivíduos com disfunção moderada e severa foram classificados economicamente por meio do Critério de Classificação Econômica Brasil (CCEB), responderam à tradução do Questionário de Avaliação do Sono de Toronto (SAQ) e a Escala de Reajustamento Social (SRRS), para verificar o grau de estresse. Realizou-se também exame eletrovibratográfico. Do total, 37 (23,1%) indivíduos apresentavam disfunção moderada ou severa, sendo que destes, 20 (54,1%) eram do sexo feminino, 21 (56,8%) pertenciam a “Classe D”, 29 (78,4%) apresentavam distúrbios do sono, 24 (64,8%) graus mais elevados de estresse e 19 (51,4%) vibração articular. Há associação estatisticamente significativa da qualidade do sono e classe econômica na ocorrência de vibrações articulares.This study aimed to verify the association of gender, economic class, quality of sleep and stress with the occurrence of joint vibration. The population of this study was made up initially by 160 individuals of both sexes in the city of Piacatu, São Paulo, Brazil, which applied the Fonseca’s Questionnaire, to check the degree of temporomandibular joint dysfunction (TMD). Later, individuals with moderate and severe dysfunction were classified economically through the Criterion of Economic Classification Brazil (CCEB), aswered to the translation of the Sleep Assessment Questionnaire of Toronto (SAQ) and the Social Readjustment Rating Scale (SRRS), to verify the degree of stress. There was also an examining of electrovibratographic. From the total, 37 (23.1%) subjects had moderate or severe dysfunction, of which 20 (54.1%) were female, 21 (56.8%) belonged to “D Class”, 29 (78.4%) had sleep disorders, 24 (64.8%) higher degrees of stress and 19 (51.4%) joint vibration. There is a statistically significant association between quality of sleep and economic class in the occurrence of joint vibration

Electromyographic evaluation of masseter and anterior temporalis muscles in resting position and during maximum tooth clenching of edentulous patients before and after new complete dentures.

The aim of this study was to assess the electrical activity of the masseter and anterior temporal muscles in patients with severe bone resorption, with complete dentures worn for over ten years, and five months after having new dentures put in place. The RDC questionnaire was applied to twelve asymptomatic patients, before and five months after new dentures were put in place. The electrical activity recordings were made in the mandibular position at rest, and during maximum tooth clenching. The electrical activity of the masseter and anterior temporal muscles in the position at rest presented no statistically significant difference after five months of wearing the new complete dentures. Electrical activity during tooth clenching exhibited a statistically significant reduction only in the right temporal muscle. A period longer than five months of wearing the new complete dentures is required for adaptation and the acquisition of functional capacity

Joint Vibration Analysis in Patients with Articular Inflammation

The study of articular sounds using a computerized system (SonoPAK) in patients with temporomandibular disorders (TMD) of inflammatory origin revealed an increase of vibratory energy when compared to asymptomatic individuals. The following conclusions were reached: 1. The amount of vibratory energy registered in these patients ranged from 8.50 to 57.61 Hz. The major vibrations occurred in the middle of the mandibular opening cycle; 2. The mean vibratory energy measured at less than 300 Hz was between 5.70 and 48.64 Hz and at higher than 300 Hz was between 3.70 and 8.99 Hz; 3. The peak amplitude in the patients with inflammation ranged from 0.35 to 3.96 Pascal and the peak of frequency from 83.20 to 120.20 Hz
