ABSTRACT
Evaluation of shear bond strength of bonding material bonded with primer and without primer
Dr Kuldeep Singh, Dr Rajesh Chaudhary
ABSTRACT
Background: To evaluate the shear bond strength of bonding material bonded with or without primer. Materials & methods: A total of 80 extracted premolar teeth were divided into two groups: Group I and Group II, each of which contained two subgroups (with one subgroup pre treated with a primer and the other, not pre treated with the primer). Results: In Group I, the mean bond strength of Transbond XT without primer (12.44MPa) was compared to that of Transbond XT with XT primer (13.06MPa). Conclusion: The shear bond strength of the brackets bonded with Transbond XT and Phase II without using the primer was sufficient.
