To compare the efficacy of different surface treatments (fiber post) with laser activated irrigation (LAI) technique (various root canal solutions) on root canal dentine in terms of push-out bond strength (PBS) in a fiber post. In this study, 200 premolars were assigned into groups according to various irrigation techniques: 2.5% sodium hypochlorite (NaOCl), 17% ethylene diamine tetra acetic acid (EDTA), and 17% EDTA + LAI. In addition, the fiber posts were separated into five groups, (n = 30) according to the surface pretreatment performed: sandblasting, hydrofluoric acid (HF), Erbium, Chromium:Yttrium Scandium-Gallium-Garnet (Er,Cr:YSGG) laser, Neodymium-Doped Yttrium Aluminum Garnet (Nd,YAG) laser and as untreated surface. The posts were cemented using dual-cure resin cement and subjected to a PBS test. Data were analyzed by one way-ANOVA, Tukey, and Tamhane T2 tests. The PBS values were increased in all parts of the tooth in the EDTA and EDTA + LAI treated groups and in groups treated with Er,Cr:YSGG laser fiber posts. In groups in which EDTA and EDTA + LAI were applied, it was observed that dentinal tubules were open according to the distribution and number of dentinal tubule configurations. The improvement of the PBS between fiber post/resin cement/root dentine was observed via the use of fiber post surface treatments with different irrigation techniques.

使用不同冲洗技术在纤维桩与根管牙本质上进行各种表面处理的推出粘合强度

比较不同表面处理（纤维桩）与激光激活冲洗 (LAI) 技术（各种根管溶液）对根管牙本质在纤维桩中的推出粘合强度 (PBS) 方面的功效。在这项研究中，200 颗前磨牙根据不同的冲洗技术被分为几组：2.5% 次氯酸钠 (NaOCl)、17% 乙二胺四乙酸 (EDTA) 和 17% EDTA + LAI。此外，纤维桩被分成五组，（n = 30) 根据执行的表面预处理：喷砂、氢氟酸 (HF)、铒、铬:钇钪-镓-石榴石 (Er,Cr:YSGG) 激光、掺钕钇铝石榴石 (Nd,YAG) 激光和作为未经处理的表面。柱子用双固化树脂水泥粘合，并进行 PBS 测试。数据通过一种方式分析——ANOVA、Tukey 和 Tamhane T2 检验。在 EDTA 和 EDTA + LAI 处理组以及用 Er,Cr:YSGG 激光纤维桩处理的组中，牙齿的所有部分的 PBS 值均增加。在应用 EDTA 和 EDTA + LAI 的组中，观察到根据牙本质小管构型的分布和数量，牙本质小管是开放的。
