Abstract
Aim: To evaluate the prevalence of odontogenic tumours and cysts of maxillofacial area. Materials & methods: Eighty cases of odontogenic tumours and cysts of maxillofacial region is reported to the department of Oral and Maxillofacial Surgery were included for the study. The extent of the lesion, size, location and related with adjacent structures was noted. All cases were managed in department of oral surgery. Results: Among tumors ameloblastoma found in 18 (22.5%), Keratocystic odontogenic tumor(KCOT) in 8 (10%), Calcified epithelial odontogenic tumour (CEOT) in 3 (3.75%), complex odontoma in 2 (2.5%), compound odontoma in 7(8.75%), odontogenic fibroma in 3 (3.75%), cementoblastoma in 1 (1.25%), primary intraosseous squamous cell carcinoma in 2 (2.5%) and ameloblastic carcinoma in 1 (1.25%), fibroscarcoma 2 (2.5%). Cysts were radicular cyst in 13 (16.25%), residual cyst in 6 (7.5%) and dentigerous cyst in 14 (17.5%). A significant difference was observed (P< 0.05). Conservative management was performed in 19 (23.75%), excision in 31 (38.75%), enucleation in 22 (27.5%), en bloc resection in 4(5%) and marsupialisation in 4 (5%). A significant difference was observed (P< 0.05). Conclusion: Maximum cases were seen in age group 18-27 years, males had higher prevalence than females. Most common benign tumour was ameloblastoma and cyst was radicular cyst.

Introduction
Odontogenic tumors (OT) are a group of heterogeneous lesions derived from epithelial or ectomesenchymal tissues or both. The formation of odontogenic tumor and cysts may or may not proceed tooth formation.1 As defined by World health organisation (WHO) odontogenic tumors (OT) are a group of heterogeneous lesions derived from epithelial or ectomesenchymal tissues or both, which are part of the tooth-forming apparatus.2,3
Most common cystic lesions of maxillofacial region are radicular cyst, residual cyst, odontogenic cyst, dentigerous cyst, or keratocystic odontogenic tumour (KCOT) etc.4 Most common benign tumour of jaw is odontoma followed by ameloblastoma.5 The origin of odontogenic tumours (OTs) is epithelial, ectomesenchymaland/or mesenchymal elements of the toothformingtissues.1,6 Timely modification in classification of odontogenic tumours have found to be effective. Addition of Adenoid odontogenic tumour (AOT) has been performed in odontogenic tumors by WHO in year 2005. These odontogenic tumours constitute 1% of all biopsied lesions of jaws.7
