Abstract(s)
Introdução: A apneia obstrutiva do sono (AOS) é definida como episódios repetitivos de obstrução parcial ou completa da via aérea superior resultante de colapso da mesma, geralmente ao nível da faringe, que ocorrem durante o sono. De entre os sintomas característicos da AOS temos o bruxismo do sono (BS) que é um distúrbio do movimento relacionado com sono caracterizado por ranger ou apertar os dentes com frequência. O diagnóstico de BS pode comprovar-se pelo estudo polissonográfico com registo da actividade dos masséteres. Alguns estudos têm sugerido que o dispositivo oral ultrafino (Bruxchecker®) pode desempenhar um papel importante no diagnóstico do BS.
Objetivo: Avaliar a utilidade da Bruxchecker® no diagnóstico de BS, em indivíduos submetidos a polissonografia por suspeita de AOS, pela análise da área de desgaste do dispositivo durante o sono.
O estudo foi aprovado pelas Comissões de Ética do Hospital Santa Maria e da Egas Moniz, tendo todos os participantes dado o seu consentimento por escrito.
Métodos: O estudo foi uma série de casos, de natureza observacional, analítico transversal, de carácter exploratório. Cinco indivíduos que preenchiam os critérios de inclusão foram analisados, tendo-se comparado os valores médios de desgaste e a percentagem de desgaste para os padrões de contacto observados no dispositivo Bruxchecker®. Os parâmetros de avaliação do desgaste utilizados foram os padrões de contacto incisivo-canino (IC); incisivo-canino-prémolar (ICP) e incisivo-canino-pré-molar (ICPM).
Resultados: Apenas um dos indivíduos apresentou diagnóstico de BS, tendo apresentado percentagens de desgaste mais elevadas em todos os padrões de contacto, à excepção do padrão IC11-13, comparativamente com os restantes.
Conclusão: Apesar de não se poder tirar conclusões significativas deste estudo, podemos afirmar que o dispositivo Bruxchecker®, por si só, poderá não ser suficiente para diagnosticar BS, uma vez que apresenta desgaste em indivíduos sem diagnóstico comprovado por polissonografia.
Introduction: Obstructive sleep apnea (OSA) is defined as partial or complete repetitive obstruction episodes resulting from upper airways collapse, usually at pharynx level, which occur during sleep. Among the characteristic symptoms of OSA there is sleep bruxism (SB), which is a sleep-related movement disorder characterized by grinding or clenching teeth frequently. The diagnosis of SB can be confirmed by polysomnographic study and by recording the activity of the masseters. Some studies have suggested that the ultrathin oral device (Bruxchecker®) may play an important role in the diagnosis of SB. Objective: To evaluate the usefulness of Bruxchecker® in the diagnosis of SB, in subjects submitted to polysomnography due to suspected OSA, by analyzing the area of abrasion on the splint during sleep. The study was approved by the Ethics Committees of Hospital Santa Maria and Egas Moniz, all participants gave their written consent. Methods: The study was an exploratory was series of cases, observational, analytical, and transversal. Five individuals who met the inclusion criteria were analyzed, by comparing the average values of abrasion and the percentage of abrasion for the tooth contact patterns observed in the Bruxcheker® splint. The abrasion evaluation parameters used were the incisor-canine (IC), incisor-canine-premolar (ICP) and incisor-canine-pemolar-molar (ICPM). Results: Only one of the subjects was diagnosed with SB, he showed higher abrasion percentages in all contact patterns, with the exception of the IC11-13 pattern, compared to the others. Conclusion: Although it is not possible to take significant conclusions from this study, we can say that the Bruxchecker® splint alone may not be sufficient to diagnose SB, since it presents abrasion in subjects without a diagnosis confirmed by polysomnography.
