Aim: To determine the prevalence of lesions in the oral mucosa in a Peruvian population.
Materials and Methods: The sample consisted of 139 patients treated at the Moche Stomatology Clinic - Faculty of Stomatology of the National University of Trujillo, during the year 2019. A total of 139 excisional biopsies were performed and the diagnosis of the diseases or injuries was determined by histopathological studies.
Results: The prevalence of benign lesions comprised 99.28% of all diagnoses, while only 0.72% were malignant lesions.
Conclusions: Fibrous hyperplasia is the most prevalent lesion in the buccal mucosa and its most frequent location was the labial mucosa, followed by the dorsum of the tongue and the buccal mucosa.
