To determine the shear bond strength (SBS) of orthodontic brackets bonded with a self-adhering resin composite.
45 freshly extracted mandibular incisors were randomly divided into 3 groups (n = 15 per group). Brackets were bonded with 3 bonding systems and cured with an LED light. Brackets were bonded with a new self-adhering resin cement in the study group. A conventional etch-and-rinse adhesive system and a self-etching adhesive system were used for comparison. After bonding, the SBS of the brackets were tested with a universal testing machine.
Analysis of variance indicated a significant difference between groups (p<0.001). The highest values for SBS were measured in group I (21.80 ± 2.57 MPa). The SBS was significantly lower in groups II and III than in group I (P<.001). The lowest values for SBS were measured in group III (5.90 ± 0.90 MPa). SBS was significantly higher in group II than in group III (p<0.001).
The self-adhering adhesive system showed a clinically insufficient SBS, whereas the SBS of conventional etch-and-rinse adhesive system and the self-etching adhesive system were significantly higher and clinically sufficient.
测定用自粘结树脂复合材料粘结正畸托槽的剪切粘结强度（SBS）。
45颗新鲜拔除的下颌切牙随机分为3组（每组n = 15）。用3种粘结系统粘结托槽，并用LED光固化。研究组用一种新型自粘结树脂水门汀粘结托槽。使用传统的酸蚀冲洗粘结系统和自酸蚀粘结系统进行比较。粘结后，用万能试验机测试托槽的SBS。
方差分析表明各组之间存在显著差异（p<0.001）。I组的SBS值最高（21.80±2.57MPa）。II组和III组的SBS显著低于I组（P<0.001）。III组的SBS值最低（5.90±0.90MPa）。II组的SBS显著高于III组（p<0.001）。
自粘结粘结系统的SBS在临床上不足，而传统的酸蚀冲洗粘结系统和自酸蚀粘结系统的SBS显著更高且在临床上足够。
