摘　　要：目的:研究Carisolv去龋对牙本质黏结强度的影响。方法:选择30颗新鲜拔除的面中度龋损的第三磨牙,每个牙的龋洞分成两半,一半用Carisolv去龋,另一半用慢速球钻去龋,而后随机分成3组,分别使用Prime&Bond NT+Dyract AP复合体黏结;Uni-Etch(320ml/L磷酸)+One-Step Plus+Renew树脂黏结;Prompt-L-Pop+Z100树脂黏结。测试微抗拉强度(MTBS)。结果:Carisolv组3种黏结系统MTBS分别为:(17.22±7.95)MPa、(25.40±8.44)MPa、(17.66±8.33)MPa,车针组分别为:(16.01±7.43)MPa、(23.45±7.55)MPa、(16.26±7.97)MPa。2种去龋方法间差异无显著性。结论:Carisolv去龋法对以上3种黏结系统与牙本质的黏结强度无不利影响。Objective： To study the effects of Carisolv caries removal method on dentin bonding strength. Methods：Thirty extracted human third molars with moderate occlusal caries were used. Each molar was split into two parts, one part was prepared by Carisolv method and another was prepared by the low-speed hurs, Then samples were randomly divided into three groups. Three adhesive systems were used： Prime＆Bond NT ＋ Dyract AP compomer,Uni-Etch ＋ One-step plus ＋ Renew resin composite and Prompt-L-Pop ＋ Z100 resin composite. Microten- sile bonding strength（MTBS） of the three adhesive systems were tested. Results：The MTBS of the three adhensive svstems were （ 17.22 ± 7. 95 ） MPa, （25.40 ± 8.44 ） MPa, （ 17.66 ± 8.33 ） MPa in Carisolv group, and were （16.01 ±7.43） MPa, （23.45 ±7.55） MPa, （16.26±7.97） MPa in burs group, There was no significant difference between the two caries removal methods. Conclusion ：Carisolv caries removal method has no side effects on dentin bonding strength of the three adhesive systems.
