[Purpose] This study compared the effects of a short-term conservative physiotherapy program versus those of occlusive splinting on pain and range of motion in cases of Temporomandibular Joint Dysfunction. [Participants and Methods] This study included 112 male and female participants with ages ranging from 15–27 years. Outcome measures were pain assessed by the visual analogue scale and Temporomandibular Joint Range of Motion measured with the Temporomandibular joint opening index. Patients were randomly assigned to one of two groups. Conservative physiotherapy was provided to one group 3 days weekly while the other group received standard occlusive splinting. Splinting was used daily for the total period of treatment. Any adjustments for splints were done by the treating dentist. Both groups were treated for a total period of 6 weeks. [Results] Between group statistical analysis revealed a significant reduction in pain intensity and Temporomandibular joint opening index in favor of the conservative physiotherapy group. [Conclusion] Over a treatment period of 6 consecutive weeks, conservative physiotherapy could be a better initial treatment than occlusive splint in relieving pain and improving range of motion in cases of myogenic temporomandibular dysfunction.
