A retrospective analysis of the characteristics, treatment and follow-up of 26 odontomas in Greek children.
Odontomas represent the most common type of odontogenic jaw tumors among patients younger than 20 years of age. Clinically, they are often associated with eruption failure of adjacent permanent teeth, and are classified as compound and complex. The aim of the present retrospective study was to present the characteristics, treatment approach and outcome of odontomas in Greek children, over a ten-year period. Twenty six patients, 2 to 14 years of age (mean 9.3 years), with odontomas treated during the years 1999-2008 at the Department of Oral & Maxillofacial Surgery of a Children's Hospital, were included in the study. Data from patients' files were retrieved and they were recalled for review. Odontomas were equally distributed in the maxilla and mandible and 42.3% of them were located in the anterior maxilla. Of the odontomas, 80.7% were related to disturbances in tooth eruption. Bone expansion was observed in 65.3% of the cases. All odontomas were surgically removed, and related impacted permanent teeth were either left to erupt spontaneously, orthodontically guided into occlusion or were removed. Orthodontic intervention appeared to be necessary in older children, while in younger children spontaneous eruption was frequent. In the present study, odontomas were associated with unerupted or impacted teeth. Radiographic examination was essential to verify the presence of the tumor and early removal prevented tooth eruption failure and disturbances in a majority of the cases.
