PURPOSE This study evaluated, in vitro, the capacity of a dentin bonding agent to improve the bond strength of orthodontic brackets using air abrasion enamel preparation. METHODS Each of the enamel surfaces received a different treatment prior to bonding procedures. Group 1 received acid-etched with 38% phosphoric acid for 30 seconds. Group 2 received acid-etched with 38% phosphoric acid for ...

This study aimed to assess in vitro cytotoxicity for Adper™ Scotchbond™ 1 XT (SB1), Clearfil™ SE Bond 2 (CSE) and Universal (SBU), using MDPC-23 cell cultures. The metabolic activity, protein content, death types cellular morphology were evaluated. All extracts determined a significant reduction metabolism viability. CSE significantly reduced cell’s activity at its higher concentrations (50% 10...

AIM The goal of this study was to evaluate nanoleakage within the hybrid layer yielded by etch-and-rinse and self-etch adhesive systems, with different solvents and compositions. MATERIALS AND METHODS Four adhesives were applied onto 20 human dentin disks: group A: Adper Scotchbond 1XT(™) (3M ESPE), group B: One Coat Bond(®) (Coltène Whaledent), group C: AdheSE(®) (Ivoclar Vivadent) and group...

Objective. The aim of this in vitro study was to determine the shear bond strength (SBS) and adhesive remnant index (ARI) score of two self-etching no-mix adhesives (iBond™ and Scotchbond™) on different prosthetic surfaces and enamel, in comparison with the commonly used total etch system Transbond XT™. Materials and Methods. A total of 270 surfaces (1 enamel and 8 restorative surfaces, n = 30)...

The purpose of this study was to observe the pulpal response of bacterially infected cavities restored with either Gluma or Scotchbond. Cl V cavities (120) were distributed throughout the dentitions of five adult Macaca mulatta monkeys at intervals of 8 and 90 days. Each cavity was left open to the oral microflora for 48 hours to allow bacterial invasion of the remaining dentin. Six treatment g...

The objective of this research was to investigate the resin-dentin interface of three adhesive systems, Scotchbond Multi-Purpose, Optibond and Denthesive Bond II by scanning electron microscopy. The adhesives and their respective composite resins were applied inside the cervical root canal of human incisors and canines according to manufacturer recommendations. The teeth were embedded in acryli...

The aim of this study was to evaluate in fibroblast cultures the direct cytotoxic effects of etch-and-rinse, self-etch, and universal adhesive systems. The sterile glass cover slips (n = 3) were then immersed in culture medium to obtain the eluates for the experimental groups: (1) Adper™ Single Bond 2; (2) Ambar; (3) Adper™ Scotchbond™ Multi-Purpose; (4) Scotchbond™ Universal; (5) Ambar Univers...

OBJECTIVES This study aimed to compare the shear bond strength (SBS) of composite to stainless steel crowns (SSC) using two mechanical surface treatments (MSTs) and two bonding systems. MATERIALS AND METHODS Eighty-four SSCs were divided into six groups of 14; Group1: No MST+Scotchbond Universal adhesive (N+U), Group 2: Surface roughening by a diamond bur+Scotchbond Universal adhesive (R+U), ...

Materials and Methods: For the microtensile test, 12 human extracted molars stored in a 0.5% chloramine T solution were used, providing 3 teeth per adhesive system, half of which were used for bond strength tests on enamel, and the other half for adhesion testing on dentin. Resin composite was bonded incrementally to the prepared surfaces, using the adhesives Adper Scotchbond 1 [Adper Single Bo...
