Sixty premolar teeth and sixty brackets were randomly and equally divided into five groups: Transbond XT (TXT) as the control, Maxcem Elite (ME) without etching, ME with etching (ME/Etch), Vertise Flow (VF) without etching, and VF with etching (VF/Etch). Respective SBS results of the five groups were 9.86 +/- 3.20, 4.67 +/- 2.94, 7.82 +/- 2.56, 2.55 +/- 0.77, and 7.89 +/- 1.17 MPa. SBS values of the new self-etch adhesive systems were significantly lower than the traditional etch-and-rinse control (p<0.005). However, no significant differences were found between TXT and the self-adhesives applied with etching (p>0.005). After debonding, ARI scores 0 and 1 were predominant in non-etched ME and VF groups. It was concluded that new self-etch, self-adhesive bonding systems require additional phosphoric acid application to achieve comparable SBS values as the traditional orthodontic bonding agent.eninfo:eu-repo/semantics/openAccessShear bond strengthSelf-adhesive resin cementSelf-adhesive flowable compositeOrthodontic bracket bondingArticle31694795310.4012/dmj.2012-103232071992-s2.0-84871165939Q1WOS:000324898000008Q4
