This study evaluates how pre-treatment with an MDP-containing cleaning agent (Katana Cleaner, Kuraray) influences the micro-shear bond strength (µSBS) of saliva-contaminated zirconia when used with universal adhesive (UA) systems. Rectangular specimens (2 mm × 12 mm × 15 mm) were obtained (IPS, e.max ZirCAD, MO, B65L17, Ivoclar Vivadent) and divided into three groups; a non-contaminated group (control group)(CON), a contaminated and cleaned with isopropyl alcohol group(ISP), and lastly, a group contaminated and cleaned with an MDP-containing cleaning agent(KAC). Each group was then subdivided into three subgroups according to the UAs used ( = 12). Composite cylinders were prepared and bonded to each surface with Panavia V5 (Kuraray, Noritake Dental). A µSBS test was performed and the data were evaluated with the two-way analysis of variance (two-way ANOVA) and multiple comparisons test (α = 0.05). The highest µSBS values were obtained in the non-contaminated group ( < 0.001), regardless of UAs. All subgroups showed lower µSBS values after saliva contamination, but KAC resulted in significantly higher µSBS values than 99% isopropanol ( < 0.001). Overall, the lowest µSBS value was obtained with 99% isopropanol. The KAC-Clearfil UA subgroup resulted in statistically significantly higher µSBS values than the other UAs ( = 0.035 and 0.007), although all three UAs resulted in sufficient µSBS values. This study revealed that applying KAC followed by a UA containing phosphate monomers produces promising results for improving µSBS values of zirconia, greater than results using 99% isopropanol. An MDP-containing cleaning agent followed by a phosphate monomer containing a universal adhesive is a promising method to obtain acceptable bonds with saliva-contaminated zirconia ceramics.
本研究评估了使用含1,25-二羟基维生素D3（MDP）的清洁剂（Katana Cleaner，可乐丽公司）进行预处理，在与通用粘合剂（UA）系统一起使用时，对受唾液污染的氧化锆的微剪切粘结强度（µSBS）有何影响。制备了矩形试样（2毫米×12毫米×15毫米）（义获嘉伟瓦登特公司的IPS、e.max ZirCAD、MO、B65L17），并将其分为三组：未受污染组（对照组）（CON）、用异丙醇污染并清洁组（ISP），最后是用含MDP的清洁剂污染并清洁组（KAC）。然后根据所使用的UA将每组再细分为三个亚组（每组n = 12）。制备复合圆柱体，并用Panavia V5（可乐丽公司，能登齿科）粘结到每个表面。进行了µSBS测试，并使用双向方差分析（双向ANOVA）和多重比较检验（α = 0.05）对数据进行评估。无论使用何种UA，未受污染组均获得了最高的µSBS值（P < 0.001）。所有亚组在唾液污染后µSBS值均降低，但KAC组的µSBS值显著高于99%异丙醇组（P < 0.001）。总体而言，99%异丙醇组的µSBS值最低。KAC-Clearfil UA亚组的µSBS值在统计学上显著高于其他UA组（P = 0.035和0.007），尽管所有三种UA均产生了足够的µSBS值。本研究表明，先应用KAC，然后使用含磷酸盐单体的UA，对于提高氧化锆的µSBS值产生了有前景的结果，优于使用99%异丙醇的结果。含MDP的清洁剂之后再使用含磷酸盐单体的通用粘合剂是一种有前景的方法，可与受唾液污染的氧化锆陶瓷获得可接受的粘结。
