摘要
目的:评价化学机械去龋系统CarisolvTM对龋病内层牙本质黏结强度的影响。方法:40个人离体中龋磨牙,随机分成2组,分别用慢速手机球钻和CarisolvTM去龋,然后用黏结剂Prime&Bond NT或Contax黏结,复合树脂(Chrisma A2)充填。制备测试微拉伸黏结强度的龋病内层牙本质条状试件,在万能材料实验机上测定黏结强度。结果:CarisolvTM去龋,用两种黏结剂黏结后牙本质的黏结强度为,Prime&Bond NT:(22.86±3.42)MPa;Contax:(28.15±5.39)MPa。慢速手机球钻去龋,两种黏结剂黏结后的牙本质黏结强度为,Prime&Bond NT:(22.23±4.26)MPa;Contax:(26.68±6.41)MPa。结论:CarisolvTM去龋对牙本质黏结强度无显著影响。
AIM ： To evaluate the influence of CarisolvTM （ Medi Team） for resin adhesion. METHODS ： 40 extracted permanent teeth with coronal carious lesions extending into mid - dentin were used. Caries were removed with Carisolv or rotating round burs. After clinical caries excavation, the occlusal cavities in each experimental group were restored with either Prime＆Bond NT or Contax, then filled with Chrisma resin （Kulzer） . Matchstick - shaped samples through the bond interfaces between composite resin and caries - affected dentine were sectioned and microtensile bond strengths recorded. RESULTS： The microtensile bond strengths between resins and dentin with Carisolv caries removal and round burs caries removal were as follows： Carisolv^TM groups： Prime＆Bond NT： （22. 86 ± 3.42 ） Mpa; Contax： （28.15 ± 5.39） Mpa. Round burs groups ： Prime＆Bond NT： （ 22.23± 4. 26 ） Mpa; Contax ： （ 26.68± 6.41 ） Mpa. CONCLUSIONS ： From the data generated by this study it could be concluded that the use of Carisolv^TM gel excavation did not compromise bond strengths to caries - affected dentine in either group tested.
