Aim:
To survey the paediatric oral lesions in Thailand.
Design:
Biopsy records over a 15-year period (1990-2004) were retrieved from the files of the Department of Oral Pathology, Faculty of Dentistry, Chulalongkorn University. Paediatric cases with an age of 16 years or younger were selected. The age of the patients was divided into three groups according to the dentition period. The lesions were classified into three categories: inflammatory/reactive lesions, cystic lesions, and tumour/tumour-like lesions.
Results:
From a total of 8314 oral biopsies, 1251 cases (15.05%) were in the paediatric population. The greatest number of lesions fell into the cystic category, followed closely by the inflammatory/reactive category and tumour/tumour-like category, respectively. The top ten most frequently encountered lesions in the present study were dentigerous cyst, mucocele, pyogenic granuloma, ameloblastoma, radicular cyst, odontoma, odontogenic keratocyst, irritation fibroma (focal fibrous hyperplasia), fibrous dysplasia, and osteomyelitis. The majority of lesions were found in the mixed dentition period (49.24%). There was no statistical difference in the occurrence between genders in this study.
Conclusions:
The present study shows an almost similar trend to previous studies except in the ranking among and within categories. These differences may be attributable to the nature of the population studied and because Chulalongkorn University is a major referral centre.
