There was insufficient evidence to assess the effect of bonding modality on demineralization rates .
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 .
Failure rate of brackets bonded with antimicrobial and fluoride-releasing, self-etching primer and the effect on prevention of enamel demineralization.
INTRODUCTION Our aim in this r and omized clinical trial was to compare the failure rates of orthodontic brackets by using 2 self-etching primers ( SEPs ) ( Transbond Plus [ 3 M Unitek , Seefeld , Germany ] and Clearfil Protect Bond [ Kuraray Medical , Okayama , Japan ] ) with a split-mouth design . Additionally , the effect of Clearfil Protect Bond was investigated regarding inhibition of plaque accumulation and demineralization . METHODS A total of 480 brackets were bonded in 24 patients with the SEPs .  The observation period was 12 months . One week after bonding and at every third recall , the plaque index and a visual rating of the enamel adjacent to the bracket were assessed at the lateral incisors and the first premolars . Additionally ,  DIAGNOdent  ( KaVo , Biberach , Germany ) values were measured . RESULTS Over the investigation time , 26 failures were recorded . Five occurred with the brackets bonded with Transbond Plus , and the rest with Clearfil Protect Bond ( P = 0.002 ) . The additionally observed parameters had no significant differences . CONCLUSIONS The failure rate with Clearfil Protect Bond was significantly higher . For our patients , who had adequate oral hygiene , there was no benefit with regard to plaque accumulation and prevention of demineralization with Clearfil Protect Bond
