Abstract

Introduction: Benign fibro osseous lesions (FOLs) are a generic designation of poorly defined group of lesions which are recognized to affect the jaws and the craniofacial bones. The normal architecture of the bone is replaced by fibrous tissue with varying amount of mineralized foci. These group of lesions are known to encircle common clinical, radiological and histopathological features.

Aim and Objectives: To assess the frequency of fibro-osseous lesions and its type and site in the jaw bone.

• Age and sex distribution of different type of fibro-osseous lesions.
• To evaluate histopathological characteristics and radiographic features in different types of fibro-osseous lesions.

Materials and Methods: A retrospective study was conducted in the department of Oral Medicine and Radiology from the period of January 2004 to November 2019. Basic clinical parameters such as age, sex, site, progression, duration, family history, history of trauma, associated symptoms, teeth in the vicinity of the lesion, treatment and recurrence was noted. The radiographic appearance, histopathologic features, were also recorded and statistical analysis was done.

Result: A total of 25 cases of fibro osseous lesions were diagnosed during the study period. Age range was from 10 to 68 years with mean age of occurrence was 29.12 % and female to male ratio was 1.77. The lesions were mostly sited in the maxilla (60%). Ossifying fibroma was the most common histopathological type accounted, around 56% with peak incidence seen in the age group of 11-20 years. Fibrous dysplasia was the second most common benign fibro-osseous lesion (32%).
