Recurrence of peripheral ossifying fibroma: a case report.

The peripheral ossifying fibroma (POF) is a reactive gingival overgrowth occurring frequently in the maxillary anterior region in teenagers and young adults. They are pink to red in colour, firm to quite hard in consistency depending on the amount of bone they contain. As they enlarge, they may become ulcerated. They are commonly associated with poor oral hygiene and early periodontal disease. In the majority of cases there is no marked underlying bone involvement visible on the radiograph. Here, we report a case of peripheral ossifying fibroma which had recurred after the surgical excision.
