Giant ossifying fibroma of the mandible

Abstract

Ossifying fibroma is classified as a benign bone tumour. It is often considered to be a type of fibro-osseous lesion. It can affect both the mandible and the maxilla, particularly the mandible. This bone tumour consists of highly cellular, fibrous tissue that contains varied amounts of bone or cementum resembling calcified tissue. This case report is of an unusual peripheral ossifying fibroma involving the left side of mandible in a 22-year-old female patient, who presented to the dental department with a painless hard swelling which impaired proper breathing and mastication. The lesion was treated by surgical resection.
