A Clinical Evaluation of Filling Radiation Caries

Abstract

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.

目的 評估放射性齲充填治療的臨床療效。方法 對 1 5例放射性齲患者的 1 4 6個齲洞分別采用Ketac Molar和FujiIX充填 ,各充填 73個齲洞。臨床觀察 2年后 ,用美國公共健康部制定的評定系統 (USPHS)進行療效評估。結果 ①Ketac Molar和FujiIX 2年的完好率分別為 51 7%和52 3 % ,差異無顯著性 (P >0 0 5)。②治療失敗及缺陷主要發生在術后 1年和 2年 ,失敗的主要原因是充填體脫落 ,邊緣著色是兩組材料共有的缺陷。③兩組材料除在固位情況方面差異極顯著外 (P <0 0 1 ) ,其他項目差異均無顯著性 (P >0 0 5)。結論 放射性齲使用上述兩種材料充填治療 ,完好率較高 ,有較好的實用性 ,其中FujiIX更優于Ketac Molar。
