摘要
目的:通过临床指标和牙龈指标分析3种不同材料嵌体修复后牙Ⅱ类洞牙体缺损的疗效,为选择后牙Ⅱ类洞牙体缺损适合的修复方法提供依据。方法:后牙Ⅱ类洞牙体缺损患者120例共120颗患牙,根据患者诉求和意愿并考虑患牙的具体情况分为3组,每组40例患者40颗患牙,分别采用金属嵌体、瓷嵌体和树脂嵌体进行后牙Ⅱ类洞牙体缺损修复,以患牙的对侧同名牙或对颌同名牙作为对照组,1年后观察各项临床指标并计算牙龈指数(GI)和菌斑指数(PI),并按照临床评价标准比较3种嵌体修复后牙Ⅱ类洞1年后的临床疗效。结果:与各自对照组比较,金属嵌体修复组患者GI和PI差异有统计学意义(P<0.05),并且明显高于瓷嵌体修复组和树脂嵌体修复组(P<0.05);与各自对照组比较,瓷嵌体修复组和树脂嵌体修复组患者GI和PI差异无统计学意义(P>0.05)。3种不同材料嵌体修复后牙Ⅱ类洞牙体缺损1年后,瓷嵌体修复组和树脂嵌体修复组患者临床效果明显优于金属嵌体修复组。结论:金属嵌体、瓷嵌体和树脂嵌体修复后牙Ⅱ类洞牙体缺损对牙龈均有一定刺激,但程度不同,金属嵌体刺激最大,树脂嵌体次之,瓷嵌体最小。瓷嵌体和树脂嵌体可以达到更好的修复效果。
Objective：To analyze the curative effects of three inlays with different materials in repairing the poserior teeth class Ⅱ cavity by clinical indexes,and gigival indexes,and to provide the basis for choosing the proper repairing method for poserior teeth class Ⅱ cavity.Methods：According to patients＇ appeal and willing,120 poserior teeth classⅡ cavity from 120 patients were divided into three groups（40 teeth in each group）,and were restored by metal,ceramic and resin inlays.The contralateral teeth of ill teeth or the corresponding jaw teeth with the same name were used as control group.The clinical indexes were observed one year later,and the gigival index（GI）and the plaque index（PI）were calculated.The curative effects of three inday restorations were compared according the clinical evaluation criteria one year later.Results：Compared with control group,the GI and PI of the patients in metal inday group had significant differeces（P〈0.05）,and were higher than those in ceramic inlay group and resin inlay group（P〈0.05）.Compared with control group,the GI and PI of the patients in ceramic inlay group and resin inlay group had no significant differences（P〉0.05）.The clinical curative effects of ceramic and resin inlays were better than that of metal inlay after one year restoration of posterior teeth class Ⅱcavity.Conclusion：Three materials of inlays have some stimulation on the gigiva with different extents in repairing the poserior teeth cavity classⅡ cavity.The metal inlay has most stimulation,resin inlay is the next,and ceramic inlay has least stimulation.Ceramic and resin inlays have better reparing effects than metal inlay.
