Introduction: Buccal exostosis is bony prominence located on buccal side of alveolar ridge of maxilla or mandible. It is commonly seen in maxilla than mandible, whereas the etiology remains unclear. This article presents a rare case of bilateral maxillary buccal exostosis, distomolars and polydactyly along with surgical management of exostosis.
Case Report: A 39-year-old Yemeni male patient came to the dental OPD with a chief complain of swelling in the right and left back region of upper jaw from 12 years, which was a cosmetic concern to the patient. Patient was medically healthy with no familial history of gingival overgrowth. On examination, patient had polydactyly and bilateral mandibular distomolars. These isolated findings couldn’t be related to any syndrome after thorough examination and medical consultation. Finally, the treatment plan consisted of, oral hygiene instructions, mechanical debridement and periodontal resective osseous surgery, so as to reduce gingival inflammation and improve esthetic by removing the exostosis. Nonsurgical periodontal therapy alone did not reduce the gingival enlargement because of the bony nature of enlargement, thus necessitating surgical intervention.
Conclusion: Post-operative evaluation at 1, 3 and 12 months reveled an uneventful healing and no sign of recurrence at surgical sites.
