Background: Trismus is a restricted mouth opening due to muscle spasm, it’s one of the common problem encountered by dental practitioners and maxillofacial surgeons. It has several potential causes, and its treatment depends upon the cause. Patients suffering from trismus experience difficulties in performing activities of daily living and quality of life.

Objectives: To study the causes and treatment options of trismus at Khartoum Teaching Dental Hospital in patients among the Sudanese patients.

Methodology: This is a retrospective cross-sectional hospital-based study, with records of 501 patients with trismus who enrolled during the period from 2019-2021 to determine the most common causes of trismus in patients.

Results: A total of 501 records were included, the most common age group ranged from 16 to 30 years with male predilection 328(65.5%). Infection was the most common cause of trismus at KTDH 278(53.5%) and the most common infection was submassetric space infection (36.6%), the second most common cause of trismus was trauma 182(36.3%) and mainly mandibular fracture 107(58.8%) due to pain. Almost 339(67.7%) of records were dentate patients. About (60.3%) of trismus cases presented within days, there was a high significance between duration and prognosis (P .value=0.000), also there was a significance between patients with a history of tumors complaining of trismus and poor prognosis (P .value=0.000).

Conclusion: The most common cause of trismus was infection followed by trauma, the significance of the prognosis of trismus is associated with the causes and duration. Causes of trismus can be a life-threatening condition so the right diagnosis and correct treatment modality should be applied and put into consideration.
