Aim: The aim of this study was to evaluate the shear bond strength and the Adhesive Remnant Index (ARI) between the composites Eagle Bond and Orthobond bonded to an enamel surface conditioned with Transbond Plus Self-Etching Primer. Methods: Seventy-five bovine permanent mandibular incisors, divided into five groups (n=15) were used. In Groups 1, 2 and 4, the bonds were performed with Transbond...

Objective: This study aimed to evaluate the effectiveness of two methods of visual magnification (operating microscope and light head magnifying glass) for removal of composite flash around orthodontic metal brackets. Material and Methods: Brackets were bonded in the center of the clinical crown of sixty well-preserved human premolars. Half of the sample was bonded with conventional Transbond...

AIM To determine the shear bond strengths (SBS) of stainless steel brackets bonded with seven light-cured orthodontic adhesives after the enamel was conditioned with the same self-etching primer. METHODS A total of 140 extracted human molars were randomly divided into seven groups (N = 20). In all the groups, the enamel was conditioned with Transbond Plus SEP (TPSEP). Stainless steel brackets...

OBJECTIVE This study compared the clinical performance of orthodontic brackets bonded with Transbond adhesive paste after two primer systems: a two-stage conventional system (acid etching + Transbond XT adhesive primer) and a single-stage self-etching primer (SEP) (Transbond Plus). METHODS The sample comprised 480 metal brackets bonded to the teeth of 24 consecutive patients treated for 36 to...

Objectives: To evaluate the influence of surface treatment and adhesive system on shear bond strength failure mode orthodontic brackets bonded to polymethylmethacrylate surfaces. Methods: Ninety metal (n=15) were aged discs SR Ivocron subjected three conditions (no treatment; sandblasting with 50-?m aluminum oxide; roughening a tungsten bur), using two combinations adhesives (methylmethacrylate...

Purpose: To assess the shear bond strength (SBS) and adhesive remnant index score (ARI) of different primers in dry condition wet conditions.
 Materials Methods: A total 80 human premolars which are free from caries, cracks, fine lines were collected mounted on acrylic. These teeth randomly distributed into two groups (Assure Plus Transbond XT/MIP). Each group was again reassigned subgroup...

(1) Objective: The aim of this study was to compare the demineralization around brackets bonded with different types adhesive agents in a cariogenic suspension environment. (2) Methods: In study, 60 extracted upper first premolar teeth were divided into three groups 20 each group. Group 1, Transbond XT Primer + Light Cure Adhesive (3M Unitek, Monrovia, CA, USA), 2, GC Ortho Connect (GC Crop, To...

background: the aim of the present study is to evaluate the effects of a fl uoride-releasing composite resin bonding material on reducing enamel demineralization underneath and around orthodontic brackets and compare that with a conventional adhesive system. materials and methods: buccal surfaces of 10 intact extracted premolar teeth were divided into two parts with nail varnish and stainless s...

The purpose of this study was to assess the influence of two light units, a quartz-tungsten-halogen (QTH) and a light-emitting diode (LED), on the hardness and degree of conversion of an orthodontic composite resin. Sixty specimen disks were prepared from Transbond XT composite resin (3M Unitek) and light cured for 10, 20, and 30 seconds with a QTH (Curing Light XL 3000, 3M Unitek) or a LED (Or...

OBJECTIVE To test the stability of two conventional adhesives when combined with a low-viscosity caries infiltrant used for sealing sound enamel against toothbrush abrasion and acid challenge in vitro. MATERIALS AND METHODS Bovine enamel discs (Ø = 3 mm) randomly assigned to three groups (n = 10/group) were etched with 37% phosphoric acid for 30 s and treated with resins of different monomer ...
