ABSTRACT
Radiotherapy for head and neck tumors is a viable treatment modality. However, a wide range of potentially debilitating dental complications may be accompanied by this treatment. We report two cases of developmental disturbance of permanent tooth germs after radiotherapy. The one was that of a seven-year-old girl, who had congenitally missing teeth, and microdontia of permanent tooth germs. she had received radiotherapy for acute myelocytic leukemia at the age of 19 months. The other was that of a nine-year-old boy, in which congenitally missing teeth, microdontia, root hypoplasia, and enamel hypoplasia of permanent teeth were observed. He had undergone a course of radiotherapy for bilateral retinoblastoma at the age of 13 months.
