OBJECTIVE
The aim of the present study was to compare the shear bond strength (SBS) of three different fluoride-releasing bonding agents with a conventional adhesive system.
METHODS
Eighty-four extracted human premolar teeth were separated into four groups and embedded in acrylic molds consisting of 21 teeth in each group. Brackets were bonded with Transbond XT in group 1, Clearfil SE Protect Bond in group 2, LED Proseal in group 3, and Opalseal in group 4. After bracket bonding, the teeth were thermocycled 1000 times. SBS test was performed, and Adhesive Remnant Index (ARI) scores of the groups were assessed.
RESULTS
One-way analysis of variance test was used to compare the significant differences between the groups. Chi-square and Fisher's exact tests were used to evaluate ARI scores. The Opalseal group showed the highest bond strength, but there was no statistically significant difference between the groups in SBS values (p=0.067). The results of ARI scores were statistically significant.
CONCLUSIONS
All bonding materials used in the study showed clinically sufficient bond strengths.
目的
本研究旨在比较三种不同的释氟粘结剂与传统粘结系统的剪切粘结强度（SBS）。
方法
将84颗拔除的人类前磨牙分为四组，每组21颗，嵌入丙烯酸模具中。第1组用Transbond XT粘结托槽，第2组用Clearfil SE Protect Bond，第3组用LED Proseal，第4组用Opalseal。托槽粘结后，对牙齿进行1000次热循环。进行SBS测试，并评估各组的粘结剂残留指数（ARI）评分。
结果
采用单因素方差分析来比较各组之间的显著差异。使用卡方检验和Fisher精确检验来评估ARI评分。Opalseal组显示出最高的粘结强度，但各组的SBS值之间无统计学显著差异（p = 0.067）。ARI评分结果具有统计学意义。
结论
本研究中使用的所有粘结材料在临床上均显示出足够的粘结强度。
