Pak J Med Health Sci Jan ;12(2):802-3.

Objective of this study was to compare the mean shear bond strength of orthodontic brackets cured with or without the prior application of primer. Sixty extracted first premolars because of orthodontic reasons were included in this study. In group P, 50 teeth were cured using standardized bonding protocol including application of primer resin while 50 teeth in group P0 were cured without including step of primer application . It was concluded that application of primer resin is not necessary while bonding orthodontic metal brackets.
