Abstract
Introduction A large number of lesions of various etiopathogenesis may be found in the oral cavity. They range from benign inflammatory-hyperplastic changes to malignant tumors. The following study aims to statistically show the frequency and type of changes depending on the age and sex of patients treated in the Department of Dental Surgery of the Medical University of Warsaw. Material and methods 612 results of histopathological examinations of sections or entire lesions of the oral cavity collected from patients in the years 2012–2017 were analyzed. The results were analyzed in terms of gender, age and the site of tissue collection. Neoplasms and 8 other groups of lesions of the mucosa were distinguished. Results The most common lesion was fibroma (35%), followed by a chronic inflammatory process (15.4%), and salivary gland cysts (11.9%). Papillomas (HPV) accounted for 10.5%, epilemomas 9.64%, tumors 6.54%, cysts and ulcers 4.74% and 4.25%, respectively. Pre-neoplastic lesions were found in 70 cases. These included ulcerations, leukoplakia, changes with metaplasia, dysplasia and pseudo-neoplastic hyperplasia. The most common localization of pathological changes in the oral cavity was related to the gums. Conclusions Many lesions of various etiology may present with a similar clinical manifestation. Therefore, in order to correctly diagnose pathological changes in the oral cavity, it is necessary to conduct a thorough medical history and physical examination, and identify the factors that may have caused the lesion. A particular group of pathological changes of the oral mucosa are ulcers which, despite a conservative approach, do not respond to treatment. In such cases a neoplasm should be suspected and a section of the lesion be obtained for histopathological evaluation which is the only reliable method that allows a final diagnosis.
