Summary

To evaluate the clinical effectiveness of chlorzoxazone in comparison to orphenadrine Citrate in relieving the orofacial pain in bruxers. Subjects and Methods: 60 patients above 15-years old complaining of orofacial and temporomandibular disorder/pain, with no history of chronic systemic illness, will be recruited. Patients will randomly be allocated into two groups (n=30): the first group will receive Relaxon (chlorzoxazone) twice daily for two weeks, while the second group will receive Norgesic (orphenadrine Citrate) twice daily for two weeks as well. Pain severity will be assessed by Visual Analogue Scale (VAS) at day 0, 7, and day 14. In addition, a temporomandibular joint (TMJ) evaluation form will be utilized to assess the TMJ parameters before and after initiation of the treatment protocol, i.e at 0 and 14 days. Non parametric statistical analysis will be conducted to explain the results using SPSS V29.
