Abstract
Purpose: To evaluate bonding to dentin contaminated with primers/etchants used for adjacent ceramic repair.
Materials and methods: Mid-coronal dentin of sound human third molars was exposed and allocated to 10 experimental groups. The universal adhesive (UA) Single Bond Universal ('SBU,' 3M Oral Care), applied either in etch-and-rinse (E&R) or self-etch (SE) bonding mode, and the considered gold-standard SE adhesive Clearfil SE Bond X ('CSE,' Kuraray Noritake) were bonded to dentin contaminated with either Monobond Etch & Prime ('MEP,' Ivoclar) or IPS Ceramic Etching Gel ('HF,' Ivoclar) following 10 scenarios: phosphoric acid (PA)+SBUE&R (uncontaminated E&R UA control), HF+PA+SBUE&R, MEP+PA+SBUE&R, PA+MEP+SBUE&R, SBUSE (uncontaminated SE UA control), HF+SBUSE, MEP+SBUSE, CSESE (uncontaminated SE control), HF+CSESE, MEP+CSESE. Upon adhesive and composite application, the specimens were stored in artificial saliva at 37°C. After 1 week, all specimens were sectioned into resin-bonded dentin sticks, which were randomly distributed over two groups to be subjected to a microtensile bond-strength test immediately at 1 week or upon aging by storage in artificial saliva for 6 months. Statistics involved linear mixed-effects modeling with Bonferroni correction (P 0.05).
Results: E&R bonding to dentin contaminated with MEP or HF did not significantly differ from bonding to non-contaminated dentin (controls). However, SE bonding to MEP- and HF-contaminated dentin was significantly less effective than to non-contaminated dentin (controls). Aging for 6 months did not reduce E&R bonding as compared to the 1-week data, while SE bonding was significantly less effective upon 6-month aging. E&R bonding was affected more when dentin was contaminated with MEP before phosphoric acid (PA) etching than when dentin was contaminated with MEP after PA etching.
Conclusions: Dentin contamination with MEP and HF impacted self-etch (SE) bonding but not etch&rinse (E&R) bonding.
目的：评价邻近陶瓷修复中使用的引物/腐蚀剂对牙本质的粘结性。材料与方法：将健全的人第三磨牙中冠牙本质外露，分为10个实验组。通用粘合剂（UA） Single Bond universal ('SBU,' 3M Oral Care)，应用于蚀刻和冲洗（E&R）或自蚀刻（SE）粘合模式，以及被认为是金标准的SE粘合剂Clearfil SE Bond X ('CSE,' Kuraray Noritake)，在以下10种情况下粘合到被Monobond蚀刻和Prime （'MEP,' Ivoclar）或IPS陶瓷蚀刻凝胶（'HF,' Ivoclar）污染的牙质上：磷酸(PA)+SBUE&R（无污染E&R UA对照），HF+PA+SBUE&R, MEP+PA+SBUE&R, PA+MEP+SBUE&R， SBUSE（无污染SE UA对照），HF+SBUSE, MEP+SBUE&R， CSESE（无污染SE对照），HF+CSESE, MEP+SBUE&R。黏合剂和复合材料应用后，标本保存在人工唾液中，温度37℃。1周后，将所有标本切片成树脂粘结的牙本质棒，随机分为两组，在1周后立即或老化后在人工唾液中保存6个月进行微拉伸粘结强度测试。统计学采用Bonferroni校正的线性混合效应模型（p0.05）。结果：E&R与MEP或HF污染牙本质的结合与与未污染牙本质的结合（对照）没有显著差异。然而，SE与MEP和hf污染的牙本质的结合效果明显低于未污染的牙本质（对照组）。与1周的数据相比，6个月的老化没有减少E&R结合，而6个月的老化显著降低了SE结合的效果。牙本质在磷酸（PA）腐蚀前被MEP污染对E&R键合的影响大于磷酸（PA）腐蚀后被MEP污染的牙本质。结论：MEP和HF污染牙本质对自噬（SE）键合有影响，但对腐蚀-冲洗（E&R）键合无影响。
