Background: Oral cancer is sometimes preceded by clinically visible lesions which are noncancerous to begin with and which have therefore been termed precancerous. The most common oral potentially malignant lesions are leukoplakia, erythroplakia, and oral submucous fibrosis. A large number of these oral mucosal lesions have a tendency to transform into malignancy. Aim of the study: To study the prevalence of malignant and premalignant diseases in the patients. Materials and methods: The study was conducted in the Department of Oral pathology of the Dental institute. The study was conducted from January 2016- January 2017. The medical records of the patients were collected in the perspective of age, sex, site involved, and final histopathological diagnosis from the archives of department of oral pathology. After reviewing the medical records of the study period, we selected patients diagnosed with premalignant and malignant lesions. The records were reviewed and data was recorded for further evaluation. Results: A total of 116 medical records for the desired study period were reviewed. The number of male patients was 72 and number of female patients was 44. We observed that 39 patients’ biopsies were reported to be premalignant, 14 were malignant, and 69 were others. Of the premalignant cases, 25 cases were males and 14 cases were females. Of the malignant cases, 8 were males and 6 were females. In the premalignant cases, 9 cases were male patients and 5 patients were females. Conclusion: The prevalence of pre-malignant and malignant cases is 33% and 12% respectively. In terms of prevalence, frequency and presentation awareness of the precancerous and malignant lesions of oral cavity is beneficial for oral pathologists and general dental practitioners in making early and better diagnosis and treatment.
