Abstract
Trismus is one of the common complications which occur following the extraction of mandibular impacted third molars. This generally occurs due to low‑grade infection, repeated muscle stimulation, as well as other causes. This symptom is usually relieved after 1 to 2 weeks; however, it may persist for >1 month post‑operatively in very rare cases. The present study reports the case of a patient with trismus at 45 days following mandibular third molar extraction. The patient received local and systemic anti‑inflammatory treatment, combined with incision and drainage therapy under local anesthesia. In the present study, an analysis of the factors associated with the occurrence and development of trismus is also included, as well as appropriate management strategies in order to provide an effective treatment method for affected patients and for the prevention of trismus in the future.
