摘要
【目的】了解银汞合金和玻璃离子水门汀(GIC)充填乳磨牙Ⅱ类洞的疗效情况。【方法】作者通过采取银汞合金和GIC充填Ⅱ类洞,并定期复诊的方法,对185名患儿的511个乳磨牙Ⅱ类洞充填体随时间脱落的情况进行临床观察。【结果】随着时间的延长,充填体的完好率逐步下降,而脱落率逐年上升。在充填后的1年内,银汞合金充填体与GIC充填体在完好、完全脱落、部分脱落的发生率上差异无显著性(P>0.05);而在充填1年后,银汞合金充填体的完好率明显高于脱落率,而且其脱落率较GIC充填体明显偏低,且差异有显著性(P<0.05)。【结论】对于1年以后替换的乳磨牙的Ⅱ类洞的充填,推荐以银汞合金为好。
[Objective]To study the clinical effectivenessof filling in type Ⅱ cavities with amalgam and Glassionomer cement(GIC). [Methods]One hundred eighty five children's 511 deciduous molars filled by amalgam and GIC were selected for investigation and checked the retentive rate regularly. [Results] Retentive rate decreased with time, and there was no significant difference in retentive rate within one year between amalgam and GIC( P 〉0.05), One year after filling, the retentive rate of amalgam was higher than that of GIC significantly( P 〈0. 05)[Conclusion] It is best to use amalgam for filling type Ⅱ cavities of deciduous molars which will be replaced after more than one year in mixed dentine,
