Oral fibrous hyperplasia (OFH) is the most common benign tumor in the oral cavity. It is a reactive, inflammatory hyperplastic lesion of the connective tissue. A 44-years-old male patient with controlled type 2 diabetes mellitus and hypertension consulted to our department with the chief complaint of local mass formed within last 3 years on the right lower anterior vestibular area. Dental history of the patient revealed that gingival enlargement formed at the same region was excised 3 years ago but reoccured couple of months later. The intraoral examination revealed presence of asymptomatic, firm, sessile, 19x15 mm fibrous gingival overgrowth on #43-44 vestibular area. Patient was diagnosed as periodontitis via radiographic examination. After 3 sessions of initial periodontal treatment, size of the overgrowth was reduced to 17x13 mm, and edematous state of the lesion was controlled. Internal bevel incision was made and mucoperiosteal flap was reflected. Ostectomy and osteoplasty were performed after degranulation. Primary closure was obtained with 5/0 resorbable suture. Sutures were removed after 7 days. The histopathologic examination confirmed OFH. No recurrence was observed during 1-year follow-up period. During the periodontal surgery instead of total excision of the lesion, thinning from the underside of the flap was preferred to preserve the keratinized tissue and improve tissue contours. Bone at the base of the lesion was removed to prevent any bone invasion. This case report presented the succesful treatment of an OFH lesion by preserving keratinized tissue together with hard tissue resection to avoid recurrence.
