106 Ketac-Silver fillings in deciduous molars were reevaluated after 1 to 3.3 years, i.e. 25 month on the average. About 90% of 50 occlusal fillings and about 84% of 56 multisurface restorations were unchanged. Without claiming statistical evidence for their conclusiveness, we consider these results as an indication that cermet cements are a useful alternative to amalgam fillings in deciduous teeth, particularly since the life of these fillings is limited to the time until the milk tooth is physiologically lost.
106颗乳磨牙中的Ketac-Silver充填物在1至3.3年后重新评估，平均为25个月。50颗咬合面充填物中约90%以及56颗多面修复体中约84%未发生变化。尽管没有统计证据证明这些结果具有决定性，但我们认为这些结果表明，金属陶瓷粘固剂是乳牙汞合金充填物的一种有用替代品，特别是因为这些充填物的使用寿命仅限于乳牙生理性脱落之前的时间。
