13. Blood contamination effect on shear bond strength of an orthodontic hydrophilic resin
OBJECTIVE: The aim of this study was to assess the impact of blood contamination on shear bond strength (SBS) and bond failure pattern of metallic brackets bonded using a new hydrophilic resin. MATERIAL AND METHODS: Eighty human premolars were randomly allocated into 4 groups (n=20) according to the bonding material and contamination pattern. GI: brackets bo

14. Mechanical properties of one and two-step fluoridated orthodontic resins submitted to different pH cycling regimes
The aim of this study is to assess the in vitro shear bond strength and adhesive remnant index (ARI) of one and two-step fluoridated orthodontic resins under conditions that simulate high cariogenic challenge. Edgewise brackets for maxillary central incisors were randomly bonded to 80 bovine incisors, using either TransbondTM Plus Color Change orthodontic re

15. Shear bond strength of orthodontic brackets bonded using halogen light and light-emitting diode at different debond times
The aim of this in vitro study was to compare the photoactivation effects of QTH (Quartz-Tungsten-Halogen) and LED (Light-Emitting Diode) on the SBS (Shear Bond Strength) of orthodontic brackets at different debond times. Seventy-two bovine lower incisors were randomly divided into two groups according to the photoactivation system used (QTH or LED). The ena

17. Shear bond strength of metallic brackets: influence of saliva contamination
OBJECTIVE: To evaluate the influence of saliva contamination on shear bond strength and the bond failure pattern of 3 adhesive systems (Transbond XT, AdheSE and Xeno III) on orthodontic metallic brackets bonded to human enamel. MATERIAL AND METHODS: Seventy-two permanent human molars were cut longitudinally in a mesiodistal direction, producing seventy-two s

18. Clinical and laboratory evaluation of metallic brackets bonded with orthodontic composites / Avaliação clinica e laboratorial da colagem de braquetes metalicos com compositos ortodonticos
The aim of this study was to assess clinically and laboratory the bracket failure rate and shear bond strength of metallic brackets bonded with orthodontic composites. The in vivo study consisted of 20 patients aged between 10.5 to 15.1 years old who had sought corrective orthodontic treatment. Brackets were bonded of the second premolar - second premolar to

19. Shear bond strength of orthodontic brackets to enamel under different surface treatment conditions
The purpose of the present study was to evaluate the shear bond strength to enamel and the adhesive remnant index (ARI) of both metallic and polycarbonate brackets bonded under different conditions. Ninety bovine permanent mandibular incisors were embedded in acrylic resin using PVC rings as molds and assigned to 6 groups (n=15). In Groups 1 (control) and 3,

20. Avaliação da resistência ao Cisalhamento de braquetes novos recolocados com diferentes resinas ortodônticas / Evaluation of shear bond strength of new metallic brackets rebounded with different orthodontic resins
The present study evaluated in vitro the shear bond strength of new bonded and rebounded metallic brackets with three orthodontic composites. Ninety extracted first superior premolars were randomly divided in three groups, according to the different tested composite. All bonding procedures followed the manufacturers specifications with a 300g standard pressu

23. Analise in vitro da resistencia ao cisalhamento de braquetes metalicos colados em varias condições de esmalte
The purpose of this study was to compare the shear bond strength of metallic brackets with the composite Transbond XT (3M Unitek, Monrovia, USA) in several enamel preparations and to evaluate, after the debonded process, the adhesive remnant index (ARI). One hundred and fourteen bovine permanent inferior incisors were included in plastic tubes, in a center p
