Abstract

Background: The purpose of this study was to determine shear bond strength and the effect on the bracket/ adhesive failure mode when an acidic primer and other etchants were used to condition the enamel surface before bonding.

Materials & methods: Group I: Brackets bonded with Ultimate cure-on-light Light-cure composite adhesive system. Group II: Brackets bonded with Ortho-one no-mix. Self-cure composite adhesive system. Group III: Brackets bonded with Light-cure glass ionomer adhesive system. Group IV: Brackets bonded with Transbond plus self etching primer.

Results: The results of this study indicated that the shear bond strength when using Transbond plus self etching primer showed the highest bond strength Group- IV(8.69 2.54 MPa) followed by Ultimate cure-on-light Group-I (8.62 1.84 MPa), Ortho-one no-mix (Bisco Inc. USA)Group-II (8.07 1.72 MPa), and least bond strength was seen in G.C. Fuji Ortho L.C. Group-III (6.01 1.6) MPa Conclusion: Use of self etching primer saves chairside time and satisfactory high bond strength was obtained. Care should be taken during debonding of ceramic brackets How to cite this article: Reddy K D, Kishore M S V, Safeena S.

酸性底漆、光固化玻璃离聚体、光固化和自固化复合胶粘剂体系的剪切粘接强度体外研究。

背景:本研究的目的是确定在粘接前使用酸性底漆和其他腐蚀剂对牙釉质表面进行调节时，剪切粘接强度和对支架/粘接破坏模式的影响。材料与方法:第一组:支架用Ultimate cure-on-light光固化复合胶粘剂系统粘合。第二组:托架与邻苯一酮无混合键合。自固化复合胶粘剂体系。第三组:用光固化玻璃离子胶粘剂体系粘接的支架。第四组:支架与Transbond结合，加上自蚀刻底漆。结果:trans - bond +自蚀刻底漆的剪切强度最高，为Group- IV(8.69 2.54 MPa)，其次为Ultimate -on-light Group- i (8.62 1.84 MPa)、Ortho-one no-mix (Bisco Inc.)。G.C. Fuji Ortho L.C. . iii组(6.01 . 1.6)MPa)粘结强度最低。结论:使用自蚀刻处理剂可节省椅边时间，获得满意的高粘结强度。本文作者:Reddy K D, Kishore M S V, Safeena S.酸性底漆、光固化玻璃离子、光固化和自固化复合胶粘剂体系的剪切粘接强度的体外研究国际口腔卫生杂志;2013;5(3): 73 - 78。
