RESUMO
Epidemiological data on the distribution of oral and maxillofacial diseases present in early childhood are scarce in the literature. This study analyzed the frequency of lesions biopsied in this region in children aged 0 to 3 years and sent for histopathological analysis in a reference oral pathology laboratory . Histopathological diagnostic data, lesion location, sex, and age were collected. Of the total of 93,950 records, 250 cases (0.27%) belonged to the age group from 0 to 3 years old. The most frequently diagnosed oral alterations were: mucocele (34/250; 13.6%); papilloma (11/250; 4.4%), giant cell fibroma (6/250; 2.4%), pyogenic granuloma (5/250; 2%) and hemangioma (3/250; 1.2%). The lip was the most affected site, followed by the gingiva and the tongue. These results generate information on the lesions most frequently diagnosed in early childhood, which facilitates the process of diagnosis and, consequently, treatment.
