Reactive lesions of the gingiva. A clinicopathological study of 741 cases.

Abstract

A series of 741 consecutive cases of localized hyperplastic lesions of the gingiva were studied. The lesions were reclassified into four groups: pyogenic granuloma, peripheral giant cell granuloma, fibrous hyperplasia and peripheral fibroma with calcification. This study indicates that there are some differences between these groups in age and sex distribution as well as in location and size of the lesion. Fibrous hyperplasia was the most common type, followed in descending order by pyogenic granuloma, peripheral fibroma with calcification and peripheral giant cell granuloma. The peripheral giant cell granuloma showed no sex predilection while fibrous hyperplasia, pyogenic granuloma and peripheral fibroma with calcification were more common in females. Pyogenic granuloma and peripheral fibroma with calcification occur in younger patients more often than fibrous hyperplasia, and thus may represent a stage in the development of fibrous hyperplasia.
