| Summary: | Background and Aim: Self-etching primers (SEPs) are used to reduce the chair side time. However, there are different SEPs that are used in orthodontics. This study is aimed to test the shear bond strength of brackets bonded using SEPs used in restorative dentistry in comparison to orthodontic SEPs.
Settings and Design: Department of Orthodontics, Post-graduate dental college, Council of Scientific and Industrial Research (CSIR) laboratory, in vitro study.
Methods and Material: Seventy-five freshly extracted human maxillary first premolar teeth were used in this study. Orthodontic maxillary first premolar McLaughlin Bennett Trevisi (MBT) metal brackets (3M Unitek) were used to bond the teeth. The study consisted of two groups. Group A: 25 teeth were etched with Orthodontic SEP Transbond Plus (3M Unitek). Group B: Experimental group which is divided into two subgroups, Experimental subgroup a and Experimental subgroup b. Subgroup a: 25 teeth were etched with Restorative purpose SEP Adper SE Plus (3M ESPE). Sub group-b: 25 teeth were etched with Restorative purpose SEP Adper Easy One (3M ESPE). In all the groups, the same adhesive material, Transbond XT (3M Unitek) was used for fixing the brackets. All the 75 teeth were subjected to shear force to test shear bond strength by using Instron machine.
Statistical Analysis: ANOVA & Scheffe multiple comparison test were used.
Results and Conclusion: Shear bond strength of brackets using orthodontic purpose SEP, Transbond Plus, is more than the SEPs used for restorative purpose, i.e., Adper SE Plus and Adper Easy One. Restorative purpose SEPs are not suitable for orthodontic bonding of brackets.
