摘　　要：目的　评估放射性龋充填治疗的临床疗效。方法　对 1 5例放射性龋患者的 1 4 6个龋洞分别采用Ketac Molar和FujiIX充填 ,各充填 73个龋洞。临床观察 2年后 ,用美国公共健康部制定的评定系统 (USPHS)进行疗效评估。结果　①Ketac Molar和FujiIX 2年的完好率分别为 51 7%和52 3 % ,差异无显著性 (P >0 0 5)。②治疗失败及缺陷主要发生在术后 1年和 2年 ,失败的主要原因是充填体脱落 ,边缘着色是两组材料共有的缺陷。③两组材料除在固位情况方面差异极显著外 (P <0 0 1 ) ,其他项目差异均无显著性 (P >0 0 5)。结论　放射性龋使用上述两种材料充填治疗 ,完好率较高 ,有较好的实用性 ,其中FujiIX更优于Ketac Molar。Objective To evaluate the clinical effects of filling for radiation carious cavities Methods 146 carious cavities of 15 patients after radiotherapy for head and neck malignancies were included and were filled with two new GIC(Ketac Molar and Fuji IX) The 2 years follow up results were evaluated with USPHS evaluation criterion Results ① The 2 years excellent rates were 51 7% in Ketac Molar and 52 3% in Fuji IX, no significant differences ② Failures and defects were mainly occurred after 1 and 2 years The main reason of failure was loss of filling Marginal staining was a common shortcoming of the two materials ③ There were no significant differences in main indexes except retention Conclusions It is successful for radiation caries to be filled with Ketac molar and Fuji IX, and is practically significant in stomatological clinic.
