Histopathological Evaluation of Odontogenic Tumors at Tertiary Care Centre

Background: Odontogenic tumors arise from remnants of embryonic tissue destined to develop into teeth & associated structure. They originate from remnants of odontogenic epithelium, mesenchymal or combination of cellular elements that comprise the toothforming apparatus, clinical behaviour ranges from hematoma like proliferation to benign and invasive neoplasm Objective: Purpose of study to analyse frequency of benign and malignant lesion, male female ratio, most common site for lesion and age of patient at the time of presentation. Material and Method: This study was carried out between January 2013 to May 2015 at department of pathology of the Tertiary Care Teaching Hospital Patient data such as patient age and histopathologies of tumors were collected. Result: We found a total no of 115 odontogenic tumors; of this 87 were benign; of which keratosis with dysplasia (10.57 %) and keratosis without dysplasia (13.91 %) are common. Twenty one were malignant of which squamous cell carcinoma is most common and 7 were inflammatory lesions. The male female ratio was 1.3:1 Conclusion: Among odontogenic tumors, benign condition is most common with mandible is the most common. The tumours show male predominance with common in 5th decade.
