This study evaluated the influence of Carisolv (Medi Team) for resin adhesion to sound human primary and young permanent dentin.
The buccal surfaces of 64 primary molars and 74 premolars were used. Two adhesive systems and resin composites were used; SD: Super-Bond D Liner DUAL (Sun Medical) and Clearfil Photo Anterior(Kuraray), and FB: Imperva Fluorobond and Lite-Fil IIA (Shofu). Ten groups were prepared. Groups 1-5 were primary dentin and Groups 6-10 were permanent dentin. Groups 1 and 6: Carisolv applied and agitated for 3min, SD was used. Groups 2 and 7: etched with 10-3 solution (Sun Medical) for 10s, SD was used. Groups 3 and 8: treated with Carisolv and then etched, SD was used. Groups 4 and 9: treated with Carisolv, FB was used. Groups 5 and 10: FB was used. The microstructural effects of Carisolv, 10-3 solution and Carisolv plus 10-3 solution applied to dentin were evaluated by SEM. In addition, the microstructure of the resin-dentin interfaces of each group were studied using SEM. Shear bond strengths (SBS) were tested, and the failed surfaces were observed using SEM. Data was statistically analyzed using ANOVA with subsequent application of post hoc Duncan's new multiple range test at p<0.05.
The effect of Carisolv on primary dentin was stronger than that to permanent dentin. The mean SBS (unit:MPa) of Groups 1-10 were: 5.6, 15.8, 7.6, 17.5, 13.5, 8.1, 16.2, 18.2, 31.4 and 15.5. The SBS of Group 9 (Carisolv treated permanent dentin) was significantly higher than those of other groups. There was no significant difference of SBS among Groups 2, 4, 5, 7, 8 and 10, Groups 3, 5 and 6, and Groups 1, 3 and 6.
Carisolv treatment before etching significantly decreased the SBS to primary dentin in SD groups, but significantly increased the SBS to permanent dentin in FB groups.
本研究评估了伢典（Medi Team）对树脂与健康人乳牙及年轻恒牙牙本质黏附的影响。
使用64颗乳牙和74颗前磨牙的颊面。采用两种黏结系统和树脂复合材料；SD：Super-Bond D Liner DUAL（太阳医疗）和Clearfil Photo Anterior（可乐丽），以及FB：Imperva Fluorobond和Lite-Fil IIA（松风）。制备了十组。第1 - 5组为乳牙本质，第6 - 10组为恒牙本质。第1组和第6组：应用伢典并搅拌3分钟，使用SD。第2组和第7组：用10 - 3溶液（太阳医疗）酸蚀10秒，使用SD。第3组和第8组：先用伢典处理然后酸蚀，使用SD。第4组和第9组：用伢典处理，使用FB。第5组和第10组：使用FB。通过扫描电子显微镜（SEM）评估伢典、10 - 3溶液以及伢典加10 - 3溶液应用于牙本质后的微观结构效应。此外，使用SEM研究每组树脂 - 牙本质界面的微观结构。测试剪切黏结强度（SBS），并使用SEM观察断裂表面。数据采用方差分析进行统计学分析，随后在p<0.05水平应用事后邓肯新复极差检验。
伢典对乳牙本质的作用比对恒牙本质更强。第1 - 10组的平均SBS（单位：MPa）分别为：5.6、15.8、7.6、17.5、13.5、8.1、16.2、18.2、31.4和15.5。第9组（用伢典处理的恒牙本质）的SBS显著高于其他组。第2、4、5、7、8和10组之间、第3、5和6组之间以及第1、3和6组之间的SBS无显著差异。
在酸蚀前用伢典处理显著降低了SD组中乳牙本质的SBS，但显著提高了FB组中恒牙本质的SBS。
