Evaluation of bracket failure rate in orthodontic patients bonded with and without primer

IntroductionPrimers are considered widely essential for bonding orthodontic brackets. However, their role in minimizing bracket failure rates has been frequently questioned.ObjectiveTo investigate the difference in the bracket failure rate in direct bonding with and without the use of orthodontic primer.Setting and designA prospective, single blinded clinical study at a private clinical practice in Ras Al Khaimah, United Arab Emirates.Methods and material38 class I bimaxillary protrusion patients requiring all first premolar extraction treatment were assigned to primer and non primer group (19/group) and bonded in a standardized manner. They were followed up from strap up till the end of treatment and bracket failure rate during the entire treatment was recorded, assessed and compared.Statistical analysisStatistical significance between the two groups was checked using Fischer’s exact test (P less than .05 was considered significant).ResultDebonding in non primer group was more than in primer group but not statistically or clinically significant.ConclusionThe bonding of brackets without using orthodontic primer is possible; however, further research is advocated.
