This study aimed to evaluate the risk factors of radiation-induced caries by using a multiple linear regression equation and to provide the basis for the effective prevention of radioactive caries.
A total of 166 patients with head and neck cancer who underwent radiotherapy were selected as subjects. The number of decayed, missing or filled surfaces were recorded. Questionnaire contents included age, sex, radiation dose, and radiotherapy techniques. Multiple stepwise regression analyses were performed to identify the risk factors of radiation-induced caries.
Multiple stepwise regression analyses indicated that the main risk factors of radiation-induced caries were plaque index, radiotherapy techniques, time after radiotherapy, and radiotherapy dose.
The awareness of dental care and caries treatment should be improved to reduce the occurrence of radiation-induced caries in patients with head and neck cancer. In addition, intensity modulated radiation therapy should be employed to decrease the radiation exposure dose received by teeth.
本研究旨在运用多元线性回归方程评估放射性龋的危险因素，为有效预防放射性龋齿提供依据。
选取166例接受放射治疗的头颈癌患者作为研究对象。记录龋失补牙面数。问卷内容包括年龄、性别、放射剂量和放疗技术。采用多元逐步回归分析确定放射性龋的危险因素。
多元逐步回归分析表明，放射性龋的主要危险因素为菌斑指数、放疗技术、放疗后时间和放疗剂量。
应提高对头颈部癌症患者口腔护理和龋齿治疗的认识，以减少放射性龋的发生。此外，应采用调强放射治疗以降低牙齿所接受的辐射暴露剂量。
