and analgesics for 3 days. As per the patient, the swelling had reduced in size after taking antibiotics. The patient did not reveal any other relevant past medical, dental, or habit history.The patient's vital signs were found to be within normal limits. On extraoral examination, a well-defined swelling of size approximately 5 cm × 3 cm was present on the left lower third of the face (Fig. 1a). The swelling was firm in consistency, non-tender on palpation with no increase in surface temperature. On intraoral examination, a bony protuberance was noted in the region of the attached gingiva of tooth number 35 (Fig. 1b) with mild tenderness on palpation in the buccal vestibule in relation to tooth number 34 and 35.Heat test for pulp vitality was performed using gutta-percha stick for tooth number 34 and 35 and the teeth elicited an immediate response suggestive of vital teeth. Fine needle aspiration cytology was performed which did not yield any fluid. Panoramic radiograph revealed an impacted supernumerary tooth with an incomplete root formation in between the apices of 35 and 36 (Fig. 2). A welldefined radiolucency with a corticated margin and an approximate diameter of 2 cm involving the apex of 35 and the mesial side of the supernumerary tooth was observed. Cone beam computed tomography (CBCT) was advised to visualize the extensions. Sagittal sections of CBCT volume revealed loss of alveolar crestal bone between 35 and 36 and the radiolucency was seen to completely encircle the impacted supernumerary tooth and extend to involve the apical third of 35 (Fig. 3a). The axial section of the left mandible revealed perforation of the buccal cortical plate at the apical level of 35 (Fig. 3b). Preliminary hematological investigations were done before surgery which revealed normal values.
