Background: Reactive localized hyperplastic lesions of the oral cavity (RHLs) are relatively common peripheral lesions which
present as a range of clinically similar lesions at dental centers. Diagnosis can be challenging if dentists are unfamiliar with their
clinicopathological across various populations.
Objective: This study reviews the pattern of distribution of RHLs of the oral mucosa in a hospital- the Obafemi Awolowo
University Teaching Hospital Complex (OAUTHC), Ile-Ife.
Materials and methods: We reviewed 10 years data from the archives of the Department of Oral Maxillofacial Surgery and
Oral Pathology, Obafemi Awolowo University, Nigeria. Information on RHLs were extracted and recorded on standardized data
forms and analyzed using STATA.
Results: The most common lesions were pyogenic granuloma (43.7%) and focal fibrous hyperplasia (39.7%), respectively. RHLs
were found to be more frequent in women (66.7%) than men (33.3%). The most common locations of involvement was the
gingivae (84.6%), and lesions were more common in the 9–29 year age group and the mean age was 37.7 (±21.1) years. The
relationship between age group and reactive lesions was however not statistically significant.
Conclusion: The major benefit of this study is an improved knowledge of the frequency and distribution of oral reactive lesions in sub-Saharan Africa which may be highly beneficial when establishing a diagnosis and treatment plan in clinical practice.
