This study was aimed to evaluate the effects of Er:YAG and Er,Cr:YSGG laser irradiation and adhesive systems on the microtensile bond strength of Fusio Liquid Dentin (FLD) which is a self-adhering composite (SAC). Twenty-four freshly extracted human molar teeth were collected, and the enamel was removed from the occlusal surface to obtain a flat dentin surface. Twenty-four teeth were randomly divided into eight groups: Group 1: only Fusio Liquid Dentin (FLD) (Petron Clinical, Orange, California, USA) was applied to the dentin surface; Group 2: 37% Phosphoricacid (i-GEL, Medicinos Linija UAB, Lithuania) + FLD; Group 3: Single Bond Universal (SBU) (3 M ESPE, Germany) + FLD; Group 4: Adper Easy One (AEO) (3 M ESPE, Germany) + FLD; Group 5: Er:YAG laser + AEO + FLD; Group 6: Er:YAG laser + SBU + FLD; Group 7: Er,Cr:YSGG laser + AEO + FLD; and Group 8: Er,Cr:YSGG laser + SBU + FLD. After thermocycling, 1 × 1 mm sticks were used for the µTBS test (n = 10). Two sticks per group were used for SEM analysis. Fractured sample surfaces were evaluated using a stereomicroscope. Group 8 showed the highest µTBS value (13.70 MPa), whereas Group 1 showed the lowest μTBS value (5.60 MPa). There were no significant differences between Groups 2, 3, and 4 (P = 0.324), but Groups 5-8 showed statistically significant results that were higher than Groups 1-4 (P = 0.012). Adhesive failure mode was predominant followed by mixed failure. The evaluation of bonding of the FLD to dentin showed that the combined use of Er:YAG and Er,Cr:YSGG lasers with SBU and AEO on dentin surfaces improved the dentinal bond strength of the FLD.
本研究旨在评估铒钇铝石榴石（Er:YAG）激光、铒铬钇钪镓石榴石（Er,Cr:YSGG）激光照射以及粘结系统对自粘结复合材料（SAC）Fusio Liquid Dentin（FLD）微拉伸粘结强度的影响。收集24颗新鲜拔除的人磨牙，去除咬合面的釉质以获得平整的牙本质表面。将24颗牙齿随机分为八组：第1组：仅在牙本质表面应用Fusio Liquid Dentin（FLD）（美国加利福尼亚州奥兰治市Petron Clinical公司）；第2组：37%磷酸（i-GEL，立陶宛Medicinos Linija UAB公司）+ FLD；第3组：单组分通用粘结剂（SBU）（德国3M ESPE公司）+ FLD；第4组：Adper Easy One（AEO）（德国3M ESPE公司）+ FLD；第5组：Er:YAG激光+ AEO + FLD；第6组：Er:YAG激光+ SBU + FLD；第7组：Er,Cr:YSGG激光+ AEO + FLD；第8组：Er,Cr:YSGG激光+ SBU + FLD。热循环后，使用1×1毫米的小棒进行微拉伸粘结强度（µTBS）测试（n = 10）。每组取两根小棒进行扫描电子显微镜（SEM）分析。使用体视显微镜评估断裂样品表面。第8组显示出最高的µTBS值（13.70兆帕），而第1组显示出最低的µTBS值（5.60兆帕）。第2、3和4组之间无显著差异（P = 0.324），但第5 - 8组显示出统计学上显著高于第1 - 4组的结果（P = 0.012）。粘结失败模式以粘结失败为主，其次是混合失败。对FLD与牙本质粘结的评估表明，在牙本质表面将Er:YAG和Er,Cr:YSGG激光与SBU和AEO联合使用可提高FLD的牙本质粘结强度。
