Prevalence of Temporomandibular Joint Disorders among Sudanese University Students

Background: Temporomandibular disorders (TMDs) are a group of conditions affecting the temporomandibular joint (TMJ), the muscles of mastication and/or associated structures. TMD is a multi-factorial disorder, commonly associated with dental, medical and mental conditions. The aim of the study was to determine the prevalence of TMD symptoms among university students. Materials and Methods: Cross sectional study for 500 university students (251 male and 249 female) aged 17- 25 years old. The data were collected using a pretested designed questionnaire and clinical examination. Results: Clicking was found to be the most prevalent symptom followed by tenderness, whereas limitation and deviation of the temporomandibular joint (TMJ) was the least prevalent. Students that live with their families and those who live under stressful conditions were more affected by temporomandibular disorder (TMD). Conclusion: The prevalence of TMD among Sudanese university students was high, clicking was found to be the most common symptom. The results are frightening and require further more comprehensive studies to recognize the risk factors associated with TMD in order to ascertain procedures for anticipation and treatment.
