To determine the effect of Ankaferd Blood Stopper (ABS) on the shear bond strength (SBS) of orthodontic attachments.
The study material consisted of 60 freshly extracted bovine permanent mandibular incisor teeth. All teeth were cleaned and randomly divided into three groups of 20 specimens and etched with 37% phosphoric acid for 15 seconds, washed, and air-dried. Teeth in groups 1 and 2 were contaminated with ABS and blood, respectively. Teeth in group 3 were only air-dried. Roth Generous maxillary central incisor brackets were bonded with Transbond XT to all teeth. SBS was applied using a universal test machine. The one-way analysis of variance (ANOVA) test was used to determine significant differences in SBS between the three groups, and Tukey honestly significant post hoc test was used to compare subgroups.
The mean bond strengths and standard deviations of groups 1, 2, and 3 were 9.58 +/- 0.95, 4.04 +/- 0.69, and 19.56 +/- 1.84 MPa, respectively.
Specimens contaminated with blood showed a statistically significant lower in vitro SBS than those contaminated with ABS. ABS may be used clinically for obtaining a blood-free tooth surface during application of the brackets on surgically exposed, impacted teeth.
确定安可福止血剂（ABS）对正畸附件剪切粘结强度（SBS）的影响。
研究材料由 60 颗新鲜提取的牛恒前磨牙组成。所有牙齿均经过清洁，并随机分为三组，每组 20 个样本，用 37%磷酸酸蚀 15 秒，冲洗并风干。第 1 组和第 2 组的牙齿分别用 ABS 和血液污染，第 3 组的牙齿仅风干。所有牙齿均用 Transbond XT 在上颌罗特通用切牙托槽上粘结。使用万能试验机施加 SBS。采用单因素方差分析（ANOVA）检验来确定三组间 SBS 的显著差异，并采用 Tukey 诚实显著事后检验来比较亚组。
第 1 组、第 2 组和第 3 组的平均粘结强度和标准差分别为 9.58±0.95、4.04±0.69 和 19.56±1.84 MPa。
与 ABS 污染相比，血液污染的标本的体外 SBS 显著降低。ABS 可在临床上用于在手术暴露、埋伏牙上应用托槽时获得无血的牙齿表面。
