To evaluate intra group and intergroup comparison between three different adhesives with and without primer. A total of 120 first premolars were selected randomly for in vivo study and are divided into six groupsGroup 1-(Transbond XT with Primer), Group 2 (Transbond XT without Primer), Group 3 (Orthofix with Primer), Group 4 (Orthofix without Primer), Group 5 (Flowable Composite with Primer), Group 6 (Flowable Composite without Primer). Metal brackets were bonded on teeth by using three different adhesives :Transbond XT, Orthofix and Flowable composite with and without primer. shear bond strength was assessed by modified testing machine with adhesive remnant index(ARI) score for different adhesives Statistical analysis showed The mean shear bond strength of Transbond XT was maximum (9.77±3.09MPa) followed by that of Orthofix (8.75±2.04MPa) and minimum of Flowable composite (7.82±1.71MPa)and ARI suggested that the fracture occurred between composite and bracket interface. Transbond XT has the highest shear bond strength while the flowable composite has the least strength but it is more than the optimal strength required hence can be used in bonding. Orthofix showed shear bond strength equivalent to Transbond XT when used without primer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
