Central odontogenic fibroma: report of 29 cases in a Korean population with tooth management

Abstract

This study presents the behavioural findings of central odontogenic fibroma (COF) in a specific ethnic group, analysing treatment methods and demonstrating how involved teeth should be managed in detail. Clinical, radiographic, and histological findings were gathered for 29 patients who visited our clinic, with all patients’ data carefully examined by radiologists and reviewed microscopically. The cohort comprised 29 patients, with 16 females and 13 males, having a mean (SD) age of 33.1 (16.0) years. Among them, 19 patients were affected in the maxilla, with 15 showing anterior preference, and palatal depression was observed in six patients. Tooth resorption was evident in 15 patients, while 10 patients showed tooth displacement. Within the cohort, 13 patients underwent tooth extraction and resection, while the remaining 16 did not have teeth extracted. Notably, there was no significant difference in recurrence observed between these two groups. This study represents the largest study to date of COF within a single ethnic group and institution. A subset of cases exhibited noteworthy features of COF. However, intriguingly, despite these characteristics, the preservation of contiguous teeth did not demonstrate a significant impact on recurrence rates.
