Contemporary oncotherapy has improved survival of children with malignant diseases, but chemotherapy and radiotherapy also have deleterious effects. This essay illustrates the effects of chemotherapy and radiotherapy on dentition in children and adolescents. The illustrated abnormalities were seen on panoramic radiographs obtained before, during, and after treatment. Included are examples of hypodontia (partial anodontia), microdontia, altered eruption patterns, and root stunting. Comparison is made with normal dental development (Fig. 1).
当代肿瘤治疗提高了患有恶性疾病儿童的生存率，但化疗和放疗也有有害影响。本文阐述了化疗和放疗对儿童及青少年牙列的影响。所展示的异常情况可见于治疗前、治疗期间及治疗后的全景X线片。其中包括牙列缺损（部分无牙症）、牙过小、萌出模式改变及牙根发育不全的例子。并与正常牙齿发育情况进行了对比（图1）。
