Effect of Different Treatment Techniques on Masseter Muscle Thickness

Summary

This study aims to evaluate the effects of different treatment techniques on masseter muscle thickness, pain levels and maximum mouth opening in patients with bruxism. The null hypothesis of the study is that there is no difference between the use of an occlusal splint and botulinum toxin on masseter muscle thickness in patients with bruxism.
