Aim: The present study was conducted to analyze the clinical and histopathological cases of odontogenic tumors (OTs).
Materials and methods: The present 10-year retrospective study comprised of 104 OTs. Parameters such as name, age, gender, clinical features, location, extension, etc were noted. H and E stained slides were carefully assessed by an oral pathologist and were classified according to the latest WHO classification of head and neck tumors.
Results: Out of 104 OTs, the most common was ameloblastoma constituting 45 cases, KCOT (28), odontoma (17), odontogenic myxoma (4), Calcifying epithelial odontogenic tumor (CEOT) (5), cementoblastoma (3) and calcifying cystic odontogenic tumor (2). The p value found to be 0.01 (significant). Common OTs was ameloblastoma (25 males and 20 males), KCOT (12 males and 16 females), odontoma (10 males and 7 females), odontogenic myxoma (3 males and 1 female), CEOT (3 males and 2 females), cementoblastoma (2 males and 1 female) and calcifying cystic odontogenic tumor (1 male and 1 female). Ameloblastoma, KCOT, and odontoma were predominantly seen in the age group 21-30 years, CEOT and cementoblastoma in age group 31-40 years. The difference was significant (P < 0.05). Common clinical features in OTs were facial disfigurement (65), swelling (78) and pain (55). The difference was non significant (P > 0.05). The average size of ameloblastoma was 6.8cm, KCOT was 4.2 cm, odontoma was 3.9 cm, odontogenic myxoma was 2.7 cm, CEOT was 5.5 cm, cementoblastoma was 3.8 cm and Calcifying cystic odontogenic tumour (COC) was 3.6 cm. The difference was non-significant (p > 0.05).
Conclusion: Mandible exhibited more OTs as compared to the maxilla. The most common lesion was ameloblastoma, KCOT, and odontomas. We observed male predominance.
Clinical significance: The study helps in assessing the occurrence of the odontogenic tumor. This is useful for identification and clinical management.
