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

Abstract

Abstract Introduction Primers are considered widely essential for bonding orthodontic brackets. However, their role in minimizing bracket failure rates has been frequently questioned. Objective To investigate the difference in the bracket failure rate in direct bonding with and without the use of orthodontic primer. Setting and design A prospective, single blinded clinical study at a private clinical practice in Ras Al Khaimah, United Arab Emirates. Methods and material 38 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 analysis Statistical significance between the two groups was checked using Fischer’s exact test ( P less than .05 was considered significant). Result Debonding in non primer group was more than in primer group but not statistically or clinically significant. Conclusion The bonding of brackets without using orthodontic primer is possible; however, further research is advocated.
