Characterization of patients with epithelial dysplasia and carcinoma in situ in the oral cavity, 2000 to 2014.

Objetive: To characterize patients diagnosed with oral epithelial dysplasia and carcinoma in situ, according to their severity, location, age, sex and smoking habits. Materials and Methods: A descriptive study, based on 126 histopathological reports of biopsies diagnosed with mild, moderate, severe epithelial dysplasia and carcinoma in situ, with information regarding anatomical location, age and gender of the patient, recorded in the biopsy reports of the histopathology services of the Faculty of Dentistry of Andrés Bello University and Major University, between the years 2000 and 2014. The dichotomous qualitative variables were described based on percentage and age using the Shapiro-Wilk test, presenting as average and standard deviation, in the STATA 12® program (StataCorpLP, Texas, USA). Result: A similar frequency was found for men and women diagnosed with OED, 53.17% and 46.83% respectively. A mild degree of OED was the most diagnosed in both sexes. The group most affected by OED was between 50 and 69 years old (57.94%) and the most frequent anatomic location was the lateral border of the tongue (34.13%). Conclusion: Most of the analyzed cases corresponded to mild degrees of dysplasia; however, it is important to always carry out a histopathological diagnosis of the lesion, patient follow-up and education regarding risk habits.
