问题的陈述。由于氧化锆桩表面光滑，二氧化硅含量不足，难以实现氧化锆桩与复合树脂核材料的可靠粘结。本研究的目的是评价不同的表面处理对氧化锆桩和复合树脂核材料之间的短期粘结强度和耐久性的影响。将80个氧化锆桩分为4组（n=20）。样本接受4种不同表面处理之一：AIRB组，空气颗粒磨损; TSC-SIL组，摩擦化学二氧化硅涂层（CoJet系统）和硅烷化（ESPE Sil）; AIRB-BSIL组，空气颗粒磨损和含MDP底漆（Clearfil SE粘合底漆）/硅烷偶联剂（Clearfil瓷粘合活化剂）混合物的应用;和TSC-BSIL组，摩擦化学二氧化硅涂料和含MDP的底漆/硅烷偶联剂混合物的应用。用光学轮廓仪测量了由空气颗粒磨损或二氧化硅涂层产生的氧化锆桩的平均表面粗糙度（Ra）。使用透明丙烯酸树脂管（长度12 mm，直径7 mm）形成复合树脂芯基（Build-it FR）。每组进一步分为2个亚组，每组10个样本，并在37摄氏度的蒸馏水中储存24小时或150天，在5摄氏度和55摄氏度之间进行37，500次热循环，停留时间为30秒。在水储存后，在水冷却下，将试样垂直于粘结界面切成2 mm厚的桩核试样。使用万能试验机以0.5 mm/min的十字头速度进行推出试验。使用SEM检查脱粘后的桩表面。数据采用单因素和双因素方差分析和Tukey多重比较检验（α = 0.05）进行分析。空气颗粒磨损和二氧化硅涂层样本的R-a值之间未检测到显著差异（P= 0.781）。TSC-BSIL组（27.1 ± 3.2 MPa）和TSC-SIL组（25.2 ± 2.4 MPa）的短期平均粘结强度在统计学上更高（P
Statement of problem. Reliable bonding between zirconia posts and composite resin core materials is difficult to achieve because of the smooth surface texture and lack of silica content of zirconia Posts.Purpose. The purpose of this study was to evaluate the effect of different surface treatments on the short-term bond strength and durability between a zirconia post and a composite resin core material.Material and methods. Eighty zirconia posts were divided into 4 groups (n=20). Specimens received 1 of 4 different surface treatments: group AIRB, airborne-particle abrasion; group TSC-SIL, tribochemical silica coating (CoJet system) and silanization (ESPE Sil); group AIRB-BSIL, airborne-particle abrasion and MDP-containing primer (Clearfil SE Bond Primer)/silane coupling agent (Clearfil Porcelain Bond Activator) mixture application; and group TSC-BSIL, tribochemical silica coating and MDP-containing primer/silane coupling agent mixture application. Average surface roughness (R a) of zirconia posts produced by airborne-particle abrasion or silica coating was measured using an optical profilometer. Composite resin core foundations (Build-it FR) were formed using transparent acrylic resin tubes (12 mm in length and 7 mm in diameter). Each group was further divided into 2 subgroups of 10 specimens and stored in distilled water at 37 degrees C, either for 24 hours or for 150 days with 37,500 thermal cycles between 5 degrees C and 55 degrees C, with a dwell time of 30 seconds. Following water storage, the specimens were sectioned perpendicular to the bonded interface into 2-mm-thick post-and-core specimens under water cooling. Push-out tests were performed with a universal testing machine at a crosshead speed of 0.5 mm/min. Debonded post surfaces were examined with SEM. Data were analyzed with 1- and 2-way ANOVA and Tukey multiple comparison tests (alpha=.05).Results. No significant differences were detected between the R-a values of airborne-particle-abraded and silica-coated specimens (P=.781). The short-term mean bond strengths for group TSC-BSIL (27.1 +/- 3.2 MPa) and TSC-SIL (25.2 +/- 2.4 MPa) were statistically higher (P
