Abstract
- The peripheral ossifying fibroma(POF) is a relatively common, non-neoplastic gingival growth that is classified as a reactive hyperplastic inflammatory lesion. The clinical appearance of POF is generally a small, well-circumscribed, focal mass with a sessile or pedunculated base. The pathogenesis of this lesion is uncertain. POFs are believed to arise from cells of the periodontal ligament as hyperplastic growth of tissue that is unique to the gingival mucosa. Approximately 60% of POFs occur in the maxilla, and 55%-60% of all cases occur in the incisor-canine area. Most lesions are less than 2 cm in size. To our knowledge, huge POF of approximately 8 cm in size in the lower posterior edentulous ridge has not been previously described in the English literature. We report an unusually huge POF overlying the lower posterior edentulous ridge mucosa, along with long-term follow up result.
