Resumo

Objectives: This study estimated the maximum tongue pressure (MTP) against teeth in bruxers, and verified the effect of a stabilization splint. Method: Forty subjects (mean age: 26.57 years) were assigned to two groups (n=20): bruxers and non-bruxers. Sleep bruxism was diagnosed by self-report, presence of tooth wear and tongue indentation, and by using a BiteStrip (TM) device. Maximum tongue pressure was measured by intraoral appliances containing pressure sensors. After baseline evaluation, bruxers received a stabilization splint and non-bruxers received a palatal splint, both for nocturnal use. Maximum tongue pressure was reassessed after 30 and 60 days. Data were submitted to repeated-measures ANOVA and Tukey test (P<0.05). Results: Bruxers showed an increased MTP against teeth (P<0.05). Splint therapy decreased MTP for bruxers and non-bruxers. Discussion: Bruxers present tongue indentations or ulcerations; however, there is no evidence on their MTP. Further research should focus on therapies to avoid tongue ulcerations in bruxers. (AU)
