This study evaluated the shear bond strengths of orthodontic brackets bonded to human premolars using five different combinations of flowable composites and one-step self-etching adhesives (n=12): (1) Adper Easy Bond+Filtek Supreme XT Flow; (2) Futurabond NR+Grandio Flow; (3) Clearfil S3 Bond+Clearfil Majesty Flow; (4) AdheSE One+Tetric EvoFlow; and (5) Transbond Plus Self Etching Primer+Transb...

BACKGROUND The aim of the present study is to evaluate the effects of a fluoride-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 st...

The aim of this investigation was to test the hypothesis that there is no difference in microleakage between composite-enamel and composite-wire interfaces, when different composites are used. Forty-five freshly extracted human mandibular incisors separated into three groups were used in the study. Multi-stranded 0.0215 inch diameter wire was bonded to enamel using two conventional (Transbond X...

OBJECTIVE To assess the adhesive resistance of metallic brackets bonded to temporary crowns made of acrylic resin after different surface treatments. METHODS 180 specimens were made of Duralay and randomly divided into 6 groups (n = 30) according to surface treatment and bonding material: G1 - surface roughening with Soflex and bonding with Duralay; G2 - roughening with aluminum oxide blastin...

OBJECTIVE The aim of this study was to compare the shear bond strength (SBS) and adhesive remnant index (ARI) scores of no-primer adhesives tested with two different bracket bases. MATERIALS AND METHODS 120 bovine permanent mandibular incisors were divided into 6 groups of 20 specimens. Two brackets (ODP) with different bracket bases (anchor pylons and 80-gauge mesh) were bonded to the teeth ...

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...

OBJECTIVE To test the null hypothesis that combining low-viscosity caries infiltrant with conventional adhesive resins would not improve sealing of sound enamel against demineralization in vitro. MATERIALS AND METHODS Bovine enamel discs (N = 60) with diameter of 3 mm were randomly assigned to six groups (n = 10). The discs were etched with 37% phosphoric acid for 30 seconds and treated with ...

Objetivo: Avaliar, in vitro, a resistência ao cisalhamento e o índice de adesivo remanescente (IAR) bráquetes colados com TransbondTM Plus Color Change. Desenho: Estudo laboratorial da cisalhamento. Metodologia: Bráquetes ortodônticos foram em dentes bovinos submetidos teste mecânico. Métodos: Quarenta cinco divididos aleatoriamente três grupos para colagem Transbond™ XT fotopolimerizado por 10...

OBJECTIVE To determine the clinical applicability of Ormocer based fowable adhesive (Admira fow) in comparison with BisGMA based adhesive (Transbond XT) and Ormocer based packable adhesive (Admira). MATERIALS AND METHODS Sixty human premolars, divided into group I (n = 20) Transbond XT, group II (n = 20) Admira and group III (n = 20) Admira fow were bonded with metal brackets using adhesives....
