Bruxism is the non-functional clenching or grinding of the teeth that may occur during sleep or less commonly in daytime. The aim of this study was to investigate the association between clinical signs and symptoms, parafunctions and associated factors of sleep bruxism in children. A population-based case-control study was carried out involving 120 children, 8 years of age, with sleep bruxism and 240 children without sleep bruxism. The sample was randomly selected from public and private schools in the city of Belo Horizonte, MG, Brazil. Groups were matched by gender and social class. The Social Vulnerability Index (SVI) drawn up by the city of Belo Horizonte was employed for social classification. Data collection instruments included clinical forms and pre-tested questionnaires. The diagnosis of sleep bruxism was supported by the American Association of Sleep Medicine (AASM) criteria. The McNemar test, binary and multivariate logistic regression models were used for statistical analysis. The risk factors associated with sleep bruxism included: primary canine wear (OR=2.3 IC 95% 1.2-4.3), biting of objects like pencils or pens (OR=2.0 IC 95% 1.2-3.3) and wake-time bruxism (tooth clenching) (OR=2.3 IC 95% 1.2-4.3). Children that present the parafunctions of object biting and wake-time bruxism were more susceptible to sleep bruxism.


Bruxismo é o ato não funcional de ranger os dentes enquanto se dorme ou apertar os dentes em vigília. O objetivo deste estudo foi investigar a associação entre sinais e sintomas clínicos associados ao bruxismo noturno em crianças. Foi desenvolvido um estudo de base populacional com desenho caso-controle, envolvendo 120 crianças, de 8 anos de idade, com bruxismo e 240 crianças sem bruxismo. A amostra foi selecionada de forma randomizada em escolas públicas e particulares da cidade de Belo Horizonte, Brasil. Os grupos caso e controle foram pareados por gênero e classe social. O Índice de Vulnerabilidade Social (IVS) desenvolvido pela prefeitura da cidade de Belo Horizonte foi utilizado para a classificação social. Como instrumentos de coleta foram utilizados: uma ficha clínica e um questionário pré-testados. O diagnóstico de bruxismo noturno foi baseado nos critérios da American Association of Sleep Medicine (AASM). Os testes estatísticos de McNemar, regressão logística binária e multivariada com modelo de regressão foram utilizados para análise dos dados. Foram considerados fatores de risco para o bruxismo noturno: desgaste em caninos decíduos (OR=2,3 IC 95% 1,2-4,3), morder objetos como lápis e canetas (OR=2,0 IC 95% 1,2-3,3) e apertar os dentes em vigília (OR=2,3 IC 95% 1,2-4,3). Crianças que apresentam outras parafunções tais como: morder objetos e apertar os dentes em vigília são mais susceptíveis ao bruxismo noturno.

Se realizó un estudio observacional, prospectivo, transversal y descriptivo de 37 ancianos de 60 a 80 años para conocer los signos y síntomas de los trastornos temporomandibulares que se presentan con mayor frecuencia en este grupo etario. Los signos y síntomas que se valoraron fueron: dolor, ruidos articulares, bloqueos, limitación funcional de la apertura mandibular, desgaste dental, pérdida de dientes, dimensión vertical, colapso posterior de la mordida y rehabilitación prostésica, entre otros. El 46 por ciento (n=17) de la población presentó patología dolorosa de la ATM acompañada por los menos con un síntoma , por ej. chasquido, bruxismo o apertura limitada; el 43.2 por ciento (n=16) tiene signos positivos de pérdida de la dimensión vertical; el 81 por ciento (n=30) presenta colapso de la mordida; el 54 por ciento (n=20) de los ancianos que no presentó dolor, está expuesto por lo menos a un factor de riesgo

This epidemiological study was conducted upon 4,590 school children to find the prevalence of oral habits in Mangalore in relation to their age and sex and to find the correlation, if any, between the habits and the malocclusion status. We noted that 29.7% of the population had habits of which 3. 1% had digit sucking, 4.6% mouth breathing, 3.02% tongue thrusting, 6.2% bruxism, 6% lip/cheek biting, 12.7% nail biting, 9.8% pencil biting and 0. 09% masochistic habits respectively. Digit sucking, pencil biting and tongue thrust were highly prevalent among Group 1 (3-6 years) children. Mouth breathing and bruxism were significant in Group 2 (7-12 years) cases whereas lip/cheek biting and nail biting were more common in Group 3 (13-16 years) cases. Digit sucking, tongue thrust, mouth breathing and bruxism were more prevalent among the boys whereas lip/cheek biting, nail biting and pencil biting were more prevalent among the girls. 28.95% of the children in Group 2 and 3 with habits had malocclusion. There was a significant correlation between class I type 2, class II div 1 and tongue thrust and mouth breathing whereas children with digit sucking showed a high correlation with class I type 2 malocclusion.
