摘　　要：目的比较银汞合金嵌体与银汞合金充填体修复后牙邻Ⅱ类洞的疗效。方法选取200例后牙邻Ⅱ类洞的中龋患者,分为银汞合金嵌体组和银汞合金充填体组,各100例,观察修复体折断、修复体松动脱落、食物嵌塞、龈炎、继发龋等5个指标。结果在继发龋、食物嵌塞、龈炎3方面银汞合金嵌体组优于银汞合金充填体组(P<0.05),其它两个指标组间无显著性差异。结论银汞合金嵌体是提高后牙邻Ⅱ类洞修复效果的有效可行方法。Objective To compare the clinical effects between amalgam inlay and amalgam restoration for molar proximal-occlusion Class Ⅱ cavity. Methods 200 teeth of class It caries with normal pulp vital were randomly divided into 2 groups of 100 teeth each and treated with amalgam inlay and amalgam restoration separately. The following 5 aspects were obrserved： broken, dislocation, interdental food impaction, gingivitis and secondary caries. Results The effect of amalgam inlay was superior to that of amalgam restoration in secondary caries, interdental food impaction and gingivitis （ P 〈 0.05 ）, whereas there was no significant different in other two aspects. Conclusion The amalgam inlay was an effective and feasible method for improving clinic effects on restoration of molar proximal-occlusion Class Ⅱ cavity.
