Objective: To estimate the effect of a vibratory splint (VibS) in reducing sleep clenching (SC) and TMD pain. Methods: Target sample was consecutive 19 TMD patients attending the Orofacial Pain Clinic at FFO-FOUSP. Patients used the VibS or acrylic occlusal splint (OS) as control for 14 days. Outcome variables were SC frequency and pain, assessed by a portable electromyography detector-analyzer (BiteStrip™) and 100 mm VAS, respectively. Statistical analyses were performed with two-way repeated measures ANOVA, and analysis of covariance (ANCOVA). Results: VibS promoted a marked decrease, whereas acrylic OS increased SC frequency after two weeks of use. Due to a significant difference in initial VAS levels between VibS and control group, the effect of the two splints on TMD pain could not be clearly estimated. Conclusion: The results suggested that VibS can potentially be used to reduce SC frequency, although further studies with larger sample size are necessary to confirm these findings.
