The purpose of this study was to compare shear bond strength and mode of failure of brackets bonded with 3 self-etching products.
The products tested were (1) a recently developed, modified self-etching, 1-step adhesive system (Adper Prompt L-Pop Self Etch Adhesive, 3M, St Paul, Minn); (2) a new fluoride-releasing, antibacterial, self-etching adhesive system (Clearfil Protect Bond, Kuraray, Osaka, Japan); and (3) a fluoride-releasing, self-etching adhesive system (Transbond Plus Self Etching Primer, 3M). Thirty-six defect-free premolars were randomly divided into 3 groups (n = 12 each), and metal brackets were bonded according to the manufacturer's instructions. Brackets were debonded in shear on a universal testing machine with a crosshead speed of 1 mm per minute.
One-way ANOVA showed a statistically significant (P < .001) difference between groups. Group 2 had the highest shear bond strength. The difference between groups 1 and 3 was not statistically significant. The Kruskal-Wallis test showed no significant differences in the ARI scores (P = .595; P < .05).
The fluoride-releasing, antibacterial, self-etching adhesive system, Clearfil Protect Bond, produced greater shear bond strength than the other 2 products tested and could be considered for clinical use.
本研究的目的是比较用3种自酸蚀产品粘结托槽的剪切粘结强度和失效模式。
所测试的产品为：（1）一种最近开发的改良型单步自酸蚀粘结系统（Adper Prompt L-Pop自酸蚀粘结剂，3M公司，明尼苏达州圣保罗）；（2）一种新型含氟、抗菌的自酸蚀粘结系统（Clearfil Protect Bond，可乐丽公司，日本大阪）；（3）一种含氟的自酸蚀粘结系统（Transbond Plus自酸蚀底漆，3M公司）。36颗无缺陷的前磨牙随机分为3组（每组n = 12），按照制造商的说明粘结金属托槽。在万能试验机上以每分钟1毫米的十字头速度进行托槽剪切脱粘试验。
单因素方差分析显示组间差异有统计学意义（P < .001）。第2组的剪切粘结强度最高。第1组和第3组之间的差异无统计学意义。Kruskal-Wallis检验显示ARI评分无显著差异（P = .595；P < .05）。
含氟、抗菌的自酸蚀粘结系统Clearfil Protect Bond比其他2种测试产品产生更高的剪切粘结强度，可考虑临床使用。
