1. Evaluation of bond strength of silorane and methacrylate based restorative systems to dentin using different cavity models
OBJECTIVE: The aim of this in vitro study was to evaluate the microtensile bond strength (µTBS) to dentin of two different restorative systems: silorane-based (P90), and methacrylate-based (P60), using two cavity models. MATERIAL AND METHODS: Occlusal enamel of 40 human third molars was removed to expose flat dentin surface. Class I cavities with 4 mm me

2. AVALIAÇÃO DA RESISTÊNCIA DE UNIÃO DE DIFERENTES SISTEMAS DE CIMENTAÇÃO ADESIVA AO ESMALTE E A DENTINA / BOND STRENGTH EVALUATION OF DIFFERENT SYSTEMS FOR ADHESIVE CEMENTATION TO ENAMEL AND DENTIN
Objective: The aim of this study was to evaluate the bond strength to enamel and dentin of a self-adhesive resin cement applied with different cementation strategies, using a conventional resin cement as control. Material and Methods: Sixty healthy human molars were selected and allocated into 6 groups (n=10) according to cementation system and dental substr

3. 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

4. Comparison of finishing and polishing systems for residual resin removal after debonding
OBJECTIVE : The aim of this study was to evaluate (1) the effectiveness of one-step polishers on the surface morphology of enamel using scanning electron microscope (SEM) and compare their effects with conventional systems for residual adhesive removal; and (2) the time spent to remove resin remnants. MATERIAL AND METHODS: Metal brackets were bonded to the b

5. Influence of human and bovine substrate on the microleakage of two adhesive systems
The aim of this study was to evaluate in vitro the marginal sealing of two adhesive systems and to analyze the influence of human and bovine substrates on marginal microleakage in enamel. Rectangular-shaped class V cavities (4 mm wide x 2 mm high x 2 mm deep) were made as follows: 8 cavities were prepared on the buccal and lingual surfaces of the human teeth

6. 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

7. Avaliação por microtração da resistência de união de diferentes sistemas adesivos ao esmalte humano
The objective of this work was to evaluate the microtensile bond strength to the human enamel of three different adhesive systems. Twenty one not prepared third molar human teeth (n=21) had been divided in three groups, with seven teeth in each group (n=7), as the used adhesive system: SB - Adper Single Bond 2 (3M/ESPE, St Paul, MN, the USA); CL - Clearfil I

8. AvaliaÃÃo da resistÃncia de uniÃo da interface adesiva de pinos de fibra de vidro e a dentina radicular / Bond strength at the adhesive interface of fiber glass posts and root dentin
The aim of this study was to assess the bond strength at the adhesive interface of fiber glass posts and root dentin, in three regions of the canal, fixed with three cementation systems. Twenty-four healthy human teeth, recently extracted for orthodontic or periodontal reasons, had their crowns removed at the cement-enamel junction with a diamond disk, under

9. Evaluation of the band strength and of the antimicrobial activity of different bracket bonding systems associated with chlorhexidina and fluor / Avaliação da resistência adesiva e da atividade antimicrobiana de diferentes sistemas de colagem de bráquetes associados à clorexidina e ao flúor.
The objective of this in vitro study was to evaluate the influence of the incorporation of fluor and chlorhexidine in the bond strength and in the antimicrobial activity of different bracket bonding systems (Transbond XT System / 3M-Unitek and Enlight System / Ormco) whose respective adhesives were pre-mixed with fluoride varnish (Fluor Protector / Ivoclar-V

10. Effect of resin and ionomer sealer materials on demineralization inhibition of occlusal pit and fissures, evaluation of enamel mineral loss and marginal adaptation / Efeito de materiais resinosos e ionomericos na inibição da desmineralização do esmalte de fissuras oclusais : estudo da perda mineral do esmalte e adaptação marginal
The occlusal surfaces are considered susceptible sites for the biofilm accumulation, which increases caries development. Pit and fissure dental sealants are recognized as an important adjunct approach for caries prevention in high caries risk patients. However, in the search for a material that has a good clinical performance, it should be considered the int

11. Cleaning treatment effects on self-etching adhesive bonding strength to unground dental enamel after salivary contact / "Efeito de tratamentos de limpeza na resistência adesiva de sistemas autocondicionantes ao esmalte dental íntegro e em contato com saliva humana"
This study evaluated the effect of different cleaning techniques in the adhesive bond strength of self-etching bonding systems to unground enamel after being in contact with human saliva. Ninety enamel fragments were obtained from dental crowns (n = 10) and the enamel surface of each fragment were kept in contact with fresh human saliva for 1 hour. Next, the

12. Effect of self-etching adhesives on intact and ground enamel / Efeito de sistemas adesivos sobre a superficie do esmalte dental integro e desgastado
The aim of this study was to evaluate the effect of the self-etching systems Prompt L-Pop (PLP-ESPE), Adper Prompt (AD-3M/ESPE) e Clearfil SE Bond (SE-Kuraray) on ground (G) and unground (U) enamel in comparison to the total-etch system Single Bond (SB-3M/ESPE). Fifty-two non-carious human third molars were used in this study. Thirty-two teeth were separated
