摘要
目的:通过测定冠修复前后龈沟液内毒素含量的变化,评价3种冠边缘设计对牙龈状况与龈沟液中内毒素含量的影响。方法:将要求烤瓷熔附金属全冠修复的就诊患者,随机分为A:肩台组、B:浅凹型肩台组、C:刃状边缘组,每组各10例。分别将修复前、修复后1个月、6个月的龈沟液样本内毒素量、龈沟液量及牙龈指数进行比较,统计学处理。结果:3组患牙冠修复后1个月各项指标明显上升。冠修复后6个月A、B两组各项指标下降至接近牙体预备前水平;C组内毒素水平无下降,牙龈指数、龈沟液量与修复后1月相比有所下降但无统计学意义。结论:只要按要求制作,A、B组龈边缘形式的修复均具有良好的效果,修复效果明显优于C组。
Objective： To investigate the influence of three kinds of crown margin designs on gingival condition and the content of endotoxin in Gingival Crevicular Fluid （GCF）. Methods： The patients who needed full crowns were divided randomly into group A： shoulder margin; group B： chamfer margin and group C： knife edge. The gingival condition and endotoxin in GCF were analysed betbre tooth preparation, one month and six months after crown placement. Then statistics analysis was preformed. Results： （1） one month after the restoration, the content level of endotoxin, amount of GCF increases and GI increased greatly in all of three groups. （2） six months after restoration, the indexes in group A and B decreased to the level similar to that of before restoration. All the parameters in Group C decreases too, but no statistical difference was found. Conclusion： Marginal configuration in both Group A and B have better clinical effect than group C.
