The aim of this study was to review the clinicopathologic features of focal reactive gingival lesions at the Lagos University Teaching Hospital, Nigeria.


A retrospective review of cases of different focal reactive gingival lesions from the records of the Departments of the Oral Biology/Oral Pathology and Oral and Maxillofacial Surgery of the Lagos University Teaching Hospital between 1970 and 2008 was carried out. Available clinical data regarding age, gender, location, estimated duration of the lesion and treatment modality were obtained and analyzed.


Prevalence rate of focal reactive gingival lesions was 5.6%. Pyogenic granuloma (PG) was the most common lesions constituting 57% of the cases. Seventeen (9.5%) of the 179 cases of PG were pregnancy induced pyogenic granuloma. The female-to-male ratio was 1.7:1. All the 4 lesions occurred more in female patients than males. The mean age of patients at presentation was 30 ± 16.5 years. The lesions were commonly seen in the second and third decade of life and least commonly seen above the age of 60 years. The lesions were equally distributed on the maxillary and mandibular gingivae, and were mostly located on the buccal gingival of the jaws. Most (51.6%) of the lesions occurred in incisors/canine region. Recurrence of the lesions was seen in 9 cases (2.9%), all pyogenic granuloma.


Focal reactive gingival lesions are relatively uncommon lesions of the oral cavity with a prevalence rate of 5.6%. The lesions occurred commonly in females, and in third decades of life. Pyogenic granuloma was the most common lesions constituting 57% of all cases.
