Abstract
Objective: This study was performed to determine the incidence of odontogenic tumours in the Thai population.
Patients and Methods: The pathology records of 1020 patients with odontogenic tumours diagnosed at the Department of Oral Pathology, Chulalongkorn University, Thailand, during a 26-year period from 1977 to 2002 were reviewed and reclassified according to the World Health Organization 1992 criteria. Clinical data, including age, gender, and anatomical distribution of lesions, were also collected and analysed.
Results: Odontogenic tumours accounted for 7.6% of all the oral and maxillofacial lesions (n = 13,472). Of these, 1010 patients (99%) had benign tumours and 10 (1%) had malignant tumours. Ameloblastoma, odontoma, and myxoma were the commonest lesions encountered. The mean age for benign odontogenic tumours was 30.0 years and for malignant lesions was 33.5 years, with the majority (54.1%) of odontogenic tumours presenting in the second and the third decades of life. Women outnumbered men for benign tumours, while the reverse was true for malignant tumours. Benign and malignant odontogenic tumours showed a predilection for the mandible, especially the posterior region.
Conclusion: Odontogenic tumours are uncommon lesions in the Thai population. The data from this study show similar trends to those from Asian and African series with minor differences.
Key words: Odontogenic, Retrospective, Thailand, Tumour
