AIM
To study in vitro the bond strength of three adhesive systems on lingual brackets.
METHODS
Forty-five extracted human mandibular premolars were randomly divided into three groups of 15 specimens each. All brackets (Stealth lingual brackets) were bonded with Transbond XT Light Cure Adhesive. In group 1, the conventional primer was used; in group 2, Transbond Moisture Insensitive Primer was employed; and in group 3, an antimicrobial self-etching primer (Clearfil Protect Bond) was used.
RESULTS
The highest mean bond strength values were observed when Clearfil Protect Bond (13.54 ± 0.58 MPa) was used and the lowest after applying the conventional Transbond XT primer (6.41 ± 0.43 MPa). The mean bond strength in group 2 was 8.20 ± 0.50 MPa, which was significantly higher than that of group 1.
CONCLUSION
Besides its antimicrobial effect, Clearfil Protect Bond results in high bond strength values. Therefore, this product might be preferable when bonding lingual brackets.
目的
在体外研究三种粘接系统对舌侧托槽的粘接强度。
方法
45颗拔除的人类下颌前磨牙随机分为三组，每组15个标本。所有托槽（隐形舌侧托槽）均使用Transbond XT光固化粘接剂进行粘接。第1组使用传统底漆；第2组使用Transbond防潮底漆；第3组使用抗菌自酸蚀底漆（Clearfil Protect Bond）。
结果
使用Clearfil Protect Bond时观察到最高平均粘接强度值（13.54±0.58MPa），使用传统Transbond XT底漆后最低（6.41±0.43MPa）。第2组的平均粘接强度为8.20±0.50MPa，显著高于第1组。
结论
Clearfil Protect Bond除具有抗菌作用外，还能产生较高的粘接强度值。因此，在粘接舌侧托槽时该产品可能更可取。
