ABSTRACT

Trismus is a multifactorial symptom which is most commonly presented after the removal of lower third molars. Upper third molar is a rare but true cause of trismus and must be included in the differential diagnosis. We present a rare case of trismus caused by the presence of malposed upper third molar, obstructing the forward movement of coronoid process of the mandible and restricting further mouth opening.
