摘　　要：背景:近年来,传统的银汞合金充填修复的缺点已日益显现。寻找其替代产品是目前研究的热点,而新型材料3M Ketac Molar超硬玻璃离子充填修复的报道尚不多见。目的:比较3M Ketac Molar超硬玻璃离子与银汞合金充填后牙窝洞的临床效果。设计、时间及地点:回顾性分析,对照观察,于2002-02/2006-04在南昌市第九医院口腔科完成。对象:选择南昌市第九医院口腔科门诊就诊的后牙龋病患者187例307颗牙,平均年龄45岁。方法:用3M Ketac Molar后牙超硬玻璃离子充填162颗后牙窝洞,银汞合金充填145颗后牙窝洞,连续观察1,2年,评价其临床效果,以充填材料完好,边缘密合,无继发龋、无磨损者为治疗成功。主要观察指标:两种材料修复后牙窝洞1,2年临床疗效。结果:3M Ketac Molar后牙超硬玻璃离子和银汞合金充填1年复查,成功率分别为96.30%,91.03%;2年复查,成功率分别为91.36%,90.34%。两组疗效差异无显著性意义(P>0.05)。结论:3M Ketac Molar后牙超硬玻璃离子既能修复缺损牙面,而且改善美观,防龋,是替代银汞合金的较好材料。BACKGROUND： The disadvantages of traditional silver amalgam filling show up increasingly in recent years. As a result, seeking its substitution has become the research focus. However, there were few reports on the new material, 3M Ketac Molar ultrahard glass ionomer cement. OBJECTIVE： To compare the clinical effects of 3M Ketac Molar ultrahard glass ionomer cements and silver amalgams on filling the dental cavities. DESIGN, TIME AND SETTING： A retrospective analysis and comparative observation was performed in the Department of Stomatology, No. 9 Hospital of Nanchang from February 2002 to April 2006. PATIClPANTS： 307 teeth from 187 patients, aged 45 on average, were selected from the Department of Stomatology of No. 9 Hospital of Nanchang. METHODS： Of all the selected dental cavities, 162 were filled with 3M Ketac Molar uitrahard glass ionomer cements and the other 145 with silver amalgams. The clinical effects were evaluated after 1 and 2 years observation, respectively. Cases, in which the filling material was intact, with marginal adoption and without recurrent caries or abrasion, were considered as the successful ones. MAIN OUTCOME MEASURES： The clinical curative effects of the two materials on filling the dental cavities were evaluated at years 1 and 2 following the filling respectively. RESULTS： According to the recheck at year 1 following filling the dental cavities, the success rates of 3M Ketac Molar ultrahard glass ionomer cements and silver amalgams were 96.30% and 91.03% respectively, and at year 2 those were 91.36% and 90.34%. There was no difference of significance between the two groups ）P 〉 0.05）. CONCLUSION： 3M Ketac Molar ultrahard glass ionomer cement is a good substitute for silver amalgam as the filling material for dental cavities, for not only can it repair dental facial defects, but also make teeth good-looking and prevent dental caries.
