Abstract
Focal reactive gingival lesions are elicited by chronic irritation primarily due to dental plaque, calculus, overhanging dental restorations and ill-fitting dental prosthesis. Persistent irritation of the gingiva can lead to tissue injury and trigger inflammation leading to proliferation of endothelial cells, multi-nucleated giant cells, fibroblasts and tissue mineralisation. The aim and objectives of the study were to determine the relative frequency and distribution of focal reactive gingival lesions according to sex, age, and anatomical site in patients who presented at the Witwatersrand Oral Health Centre. Retrospective cross-sectional study Methods Convenience sampling of patient records from the years 2011 to 2017 were analysed from the Department of Oral Pathology and the Department of Oral Medicine and Periodontology at the Witwatersrand Oral Health Centre. Sociodemographic variables and clinical features were evaluated. Female patients accounted for 70.8% (n = 172) of all focal reactive gingival lesions, with the majority of the lesions having occurred in the maxilla (56.4%; n = 137). The age of patients ranged from 3 months to 88 years. Contrary to findings in other studies, the peripheral ossifying fibroma was the most common focal reactive gingival lesion, after analysing 243 cases

Focal reactive gingival lesions (FRGL) are gingival enlargements elicited by chronic irritation primarily due to over-hanging dental restorations, ill-fitting dental prostheses, plaque and calculus[1]
Summary
Focal reactive gingival lesions are elicited by chronic irritation primarily due to dental plaque, calculus, overhanging dental restorations and ill-fitting dental prosthesis. Focal reactive gingival lesions (FRGL) are gingival enlargements elicited by chronic irritation primarily due to over-hanging dental restorations, ill-fitting dental prostheses, plaque and calculus[1]. Some authors have postulated that these pathological entities represent one lesion at various histological developmental stages[7] They argue that a LCH may develop into a POF or FFH with time through further collagen build up and maturation[8]. If this hypothesis is true, a definite age grouping for the different histological entities should be apparent
