Non-Randomized Trial of Bruxism-Related TMD Treatments

Brief Summary

This study compares three treatment approaches for adults with bruxism-related temporomandibular disorder symptoms: occlusal splint therapy, botulinum toxin type A injection, and combined medical-splint therapy. Participants were assigned to one of three non-randomized treatment arms according to clinical indication, symptom profile, shared decision-making, and patient preference. Symptom severity was assessed before treatment and after 3 months using the Fonseca Anamnestic Index. The primary purpose of the study was to compare the 3-month change in total Fonseca Anamnestic Index scores among the treatment arms. Selected symptom items and treatment-related adverse events were also evaluated during follow-up.
