CONCLUSIONS There is weak evidence indicating higher odds of failure with self-etch primer than acid etch over 12 months in orthodontic patients , and there is strong evidence that a self-etch primer is likely to result in a modest time savings ( 8 minutes for full bonding ) compared with acid etch
INTRODUCTION The use of self-etch primers has increased steadily because of their time savings and greater simplicity ; however , overall benefits and potential disadvantages and harms have not been assessed systematic ally .
In this study , we review ed r and omized controlled trials to assess the risk of attachment failure , bonding time , and demineralization adjacent to attachments between 1-stage ( self-etch ) and 2-stage ( acid etch ) bonding in orthodontic patients over a minimum follow-up period of 12 months .
A comparative assessment of the failure rate of molar tubes bonded with a self-etching primer and conventional acid-etching.
OBJECTIVES Comparative assessment of the failure rate of molar tubes bonded to first and second molars with a self-etching primer and conventional acid-etching . MATERIAL AND METHODS Four hundred forty-four molar tubes ( 246 first molar tubes and 198 second molar tubes ) were bonded , using a split-mouth design , on 62 patients ( 23 male , 39 female ; mean age 13.7 years ) with the 3 M Transbond Plus self-etching primer combined with Transbond XT paste ; or with conventional acid-etching , Orthosolo primer , and Enlight adhesive paste .  First-time failures were recorded over a period of 15 months . RESULTS Bond failure per adhesive system , arch ( maxilla-m and ible ) , quadrant ( left , right ) and tooth ( first or second molar ) were studied . Statistical analysis using logistic regression modeling ( alpha = .05 ) showed that the overall failure rate for the first and second molar tubes was 11 % ( 8 % with self-etching primer and 13 % with conventional acid-etching ) . No significant difference was found between the 2 bonding methods . Tooth location and type showed statistically significant associations . M and ibular tubes showed a 3:1 probability for failure compared to maxillary tubes . Right-sided tubes demonstrated 3 times more failures when compared to left-sided tubes , and second molar tubes showed a 3-fold increase in failure . CONCLUSION Molar tube bonding with self-etching primer shows similar success rates to conventional acid-etching , whereas the m and ibular right second molar presents the highest failure incidence
