With timely treatment, the 5 years survival rate for retinoblastoma is reported to be 99%. Dental anomalies commonly seen in these children are characterized by disturbances in shape, size, number, and mineralization in permanent teeth. The purpose of this case report is to present long-term effects of chemotherapy and radiotherapy on dental development in a patient treated for retinoblastoma in childhood and discuss its pathogenesis.
