[en] Introduction: Nocturnal bruxism is a repetitive jaw-muscular parafunction at night with higher prevalence among the infant population, and lower in the old age. The invention relates to teeth grinding and activation of facial muscles overnight, which can cause dental wear, muscle aches, headaches or dysfunctions of the temporomandibular joint, among other pathologies. Some of its treatments described are physiotherapy, botulinum toxin injections, psychological therapy? Objective: To establish the effectiveness of physiotherapeutic treatments that address nocturnal bruxism with greater evidence. Search strategy and selection of articles: The main databases in Health Sciences and Physiotherapy were consulted. Clinical trials (randomized and no-randomized) were included, as well as systematic literature reviews and/or meta-analysis where night bruxism was approached through physiotherapy techniques. In implementing the search strategy, 67 articles were compiled. We excluded 21 duplicates and 29 for their title and summary, selecting 17 for reading. After applying the inclusion and exclusion criteria, 10 were discarded, including a total of seven in the review. Synthesis and an?lisis of the results: The methodological qualities and results obtained in the seven titles were analyzed. The physiotherapeutic treatment methods used in the treatment of night bruxism were static stretching, biofeedback, neuromuscular bandaging, massage therapy and relaxation techniques. Conclusions: These results reflect scant scientific evidence of physiotherapeutic treatment in this pathology, showing improvements in symptomatology when using biofeedback, massage and neuromuscular bandaging.

[es] Introducci?n: El bruxismo nocturno es una parafunci?n mand?bulo-muscular repetitiva nocturna con mayor prevalencia entre la poblaci?n infantil, y menor en la edad anciana. Cursa con rechinamiento de dientes y activaci?n de musculatura facial durante el sue?o pudiendo originar desgastes dentarios, dolores musculares, cefaleas o disfunciones de la articulaci?n temporomandibular, entre otras patolog?as. Algunos de sus tratamientos descritos son la fisioterapia, inyecciones de toxina botul?nica, terapia psicol?gica? Objetivo: Establecer la efectividad de los tratamientos fisioter?picos que abordan el bruxismo nocturno con mayor evidencia. Estrategia de b?squeda y selecci?n de art?culos: Se consultaron las principales bases de datos en Ciencias de la Salud y Fisioterapia. Se incluyeron ensayos cl?nicos (aleatorizados y no aleatorizados), as? como revisiones bibliogr?ficas sistem?ticas y/o metaan?lisis donde se abordaba el bruxismo nocturno mediante t?cnicas de fisioterapia. Al aplicar la estrategia de b?squeda se recopilaron 67 art?culos. Se excluyeron 21 duplicados y 29 por su t?tulo y resumen, seleccionando 17 para su lectura. Tras aplicar los criterios de inclusi?n y exclusi?n, diez fueron descartados, incluyendo un total de siete en la revisi?n. S?ntesis y an?lisis de los resultados: Se analizaron las calidades metodol?gicas y resultados obtenidos en los siete t?tulos. Los m?todos de tratamiento fisioter?pico empleados en el bruxismo nocturno fueron estiramientos est?ticos, biofeedback, vendaje neuromuscular, masoterapia y t?cnicas de relajaci?n. Conclusiones: Estos resultados reflejan una escasa evidencia cient?fica del tratamiento fisioter?pico en esta patolog?a, mostrando mejoras en la sintomatolog?a al emplear la biorretroalimentaci?n, el masaje y el vendaje neuromuscular.
