Odontogenic lesions in pediatric patients.

ABSTRACT

The purpose was to evaluate our 20-year experience of pediatric odontogenic lesions. Pediatric patients with a diagnosis of odontogenic lesion were identified. Three hundred ten patients were odontogenic; dentigerous cyst was seen in 62.0% of the cases. Most (70.2%) of them occurred in mixed dentition period, and it had a male preponderance. Odontogenic keratocystic tumor occurred in the permanent dentition period. It had an equal site distribution. Odontoma was seen in 20.0% of the cases. Its site of predilection was the mandible. Ameloblastoma was the most common odontogenic tumor. Most of the cases occurred in the permanent dentition period. It affected the male and female equally. Calcifying epithelioma odontogenic tumor was seen in 11.8% of the cases. All the lesions occurred in the primary dentition period. It had no sex or site preponderance. Myxoma was seen in 3.6% of the cases. It was most common in the permanent dentition period, and it was more frequent in the male. Iliac crest bone graft was successfully performed in 28 patients, postoperative infection occurred in 2 patients, and no donor-site dysfunctions were reported. The observed differences in lesion type and distribution in this study compared with previous researches may be attributable to genetic and geographic variation in the populations studied. Iliac crest bone graft was suggested for pediatric mandible reconstruction.
