由于托槽附近的牙釉质可能受到微生物的影响，抗菌粘合剂可能是预防和减少脱矿的有用选择。本体外研究的目的是确定（1）用于正畸金属托槽的自酸蚀和抗菌自酸蚀粘合剂的剪切粘结强度和（2）使用改良粘合剂残留指数（ARI）的自酸蚀和抗菌自酸蚀粘合剂的粘结失效界面。24颗无缺损的前磨牙随机分为两组。第1组：Transbond Plus自酸蚀底漆+ Transbond XT;第2组：抗菌牙本质粘接系统（ABF）+ Transbond XT。将所有样品在37 ° C的去离子水中储存48小时。以5 mm/min的十字头速度进行剪切脱粘试验。结果（中位数、最小值、最大值）分别为：第1组：8.53、4.59、12.63;第2组：9.79、4.01、22.10。Mann-Whitney检验显示组间差异无统计学意义（P = .2，P > .05）。通过光学显微镜在16倍放大率下检查失败的托槽，以使用改良的ARI确定粘结失效界面。两组的主要失效模式均发生在托槽-粘合剂界面。ABF具有足够的机械性能和抗菌效果，使其成为正畸粘接的良好选择。
Because the enamel adjacent to brackets may be affected by microorganisms, an antibacterial adhesive may be a useful choice to prevent and reduce demineralization. The purpose of this in vitro study was to determine the (1) shear bond strength of a self-etch and an antibacterial self-etch adhesive for orthodontic metal brackets and (2) bond failure interface of a self-etch and an antibacterial self-etch adhesive using a modified adhesive remnant index (ARI). Twenty-four defect-free premolars were randomly assigned into two groups. The teeth received the following treatments-group 1: Transbond Plus Self-Etching Primer + Transbond XT; group 2: antibacterial dentin bonding system (ABF) + Transbond XT. All samples were stored in deionized water at 37 degrees C for 48 hours. Shear debonding tests were performed at a crosshead speed of five mm/min. The results in megapascals were (median, minimum, maximum) group 1: 8.53, 4.59, 12.63; group 2: 9.79, 4.01, 22.10, respectively. Mann-Whitney test revealed that the difference between the groups was not statistically significant (P = .2, P > .05). Failed brackets were examined by an optical microscope at 16x magnification to determine the bond failure interface using a modified ARI. The predominant mode of failure for both groups was at the bracket-adhesive interface. ABF may have sufficient mechanical properties and also an antibacterial effect that makes it a good choice for orthodontic bonding.
