Self-etching primers are widely used in restorative dentistry. However, only one primer has been developed for orthodontic applications. The objective of this study was to assess the suitabiliy of restorative self-etching primers on unabraded enamel.
Seven self-etching primers (Transbond™ SEP +, Xeno® III, Clearfil™ SE, Futurabond® NR, One Coat, M-Bond and OptiBond®) were compared with two conventionally-etched control groups (Transbond™ MIP). All groups with the exception of one of the two control groups underwent thermo-cycling (1000x, 5-55°C). Bovine teeth stored in physiological saline solution were used for the purpose of this study.
Both before and after thermo-cycling, the control groups presented very similar shear strengths which did not differ significantly from each other or from the Transbond™ SEP + and Clearfil™ SE specimens. During thermo-cycling, all groups except the control group and the Transbond™ SEP + specimens displayed losses from the shear bodies. These losses occurred on all of the OptiBond® samples. The adhesive remnant index (ARI) and enamel tear-outs correlated closely with the adhesive values.
Our adhesive value assessments support the conclusion that only Transbond™ SEP + and Clearfil™ SE can be recommended for clinical use.
自酸蚀底漆在修复牙科中被广泛使用。然而，仅有一种底漆被开发用于正畸应用。本研究的目的是评估修复用自酸蚀底漆在未磨损釉质上的适用性。
将七种自酸蚀底漆（Transbond™ SEP +、Xeno® III、Clearfil™ SE、Futurabond® NR、One Coat、M-Bond和OptiBond®）与两个传统酸蚀对照组（Transbond™ MIP）进行比较。除两个对照组中的一个外，所有组均进行热循环（1000次，5-55°C）。本研究使用储存在生理盐溶液中的牛牙。
在热循环前后，对照组的剪切强度非常相似，彼此之间以及与Transbond™ SEP +和Clearfil™ SE样本之间均无显著差异。在热循环过程中，除对照组和Transbond™ SEP +样本外，所有组的剪切体均出现损耗。这些损耗发生在所有OptiBond®样本上。粘结剂残留指数（ARI）和釉质撕裂与粘结值密切相关。
我们的粘结值评估支持以下结论：仅Transbond™ SEP +和Clearfil™ SE可推荐用于临床。
