“…In SEM observation, the thickness of hybrid layer or the length of resin tag were not affect the bond strength, supporting previous study that there is no correlation between bond strength and hybrid layer thickness 35) . But smoother bonding interfaces due to use of NaOCl as well as lower dentinal tubule density were thought another reason of lower bond strength in pulp chamber dentin.…”

“…46 The sealing ability of the dentin bonding seems to be correlated with the dentin location and the quality of dentin. 47 Because leakage may be observed at the cervical margins of Class V resin composite restorations, despite the use of bonding systems that create hybrid interfaces, the ability of these systems to hybridize cementum must be questioned; the literature includes only one report of hybridlayer formation in cementum. 48 Cagidiaco et al 49 considered that the leakage observed at the cervical margin may be related to the absence of dentin tubules in the limiting 100 m of the cervical margin, the relatively low number of tubules in the first 200 -300 m of the gingival floor, and the mainly organic nature of the dentin substrate.…”

The purpose of the study was to evaluate the marginal leakage of three adhesive systems in Class V resin composite restorations. Two adhesive systems containing acidic primers: Clearfil SE Bond (CSEB) and Etch & Prime 3.0 (E&P), were compared with a conventional water-based primer: Scotchbond Multipurpose Plus (SBMP). Class V cavities were made at the cementum-enamel junction of extracted human molars, which were then divided between three groups. One of the adhesive systems was applied to each group following manufacturers' instructions. Composite restorations were placed, light cured for 40 s, and polished. Specimens were then immersed in a solution of 2% basic fuchsin dye for 24 h. Longitudinal sections were obtained and studied with a stereomicroscope for assessment of the microleakage according to the degree of dye penetration (scale of 0 -3). Data were analyzed by Kruskal-Wallis one-way ANOVA, Mann-Whitney tests, and the Wilcoxon matched-pairs signed rank test. Two specimens for each group were analyzed by scanningelectron microscopy (SEM). Bonded interfaces of dentin were also examined by transmissionelectron microscopy (TEM). On enamel, there were no significant differences between the three groups. On dentin, CSEB showed the lowest dye penetration values among the three adhesive systems. SEM and TEM studies showed hybrid layer and resin tag formations in all groups.

“…The balance between demineralization depth and extension of monomer penetration of the self-etching primers is the key to a good quality adhesion between enamel and resin 23 . Self-etching primers had limited demineralization and impregnation depths because of wet dentin and ionic effects of high calcium and phosphate concentrations, which limited the apatite crystals dissolution 28 . Due to the high enamel mineral content, this effect should be considered when selfetching primers are applied in enamel.…”

ABSTRACT:With the development of composite resin polymerization techniques, LEDs were introduced to the market place. Based on the studied literature, the aim of this study was to evaluate, through microtensile testing, the bond strength to enamel of a composite resin associated to a conventional (multi-bottle) adhesive system or to a self etching primer adhesive system, polymerized by halogen light or LED (light emitting diode). Bovine teeth were divided into 4 groups with 10 teeth each (n = 10). Then the adhesives Scotchbond Multipurpose Plus (3M-ESPE) and Clearfil SE Bond (Kuraray) were applied following the manufacturers' instructions. Both systems were polymerized for 10 s by halogen light (Degulux Soft Start -Degussa Hulls) set at 550 mW/cm 2 or by LED (Kerr Demetron) set at 600 mW/cm 2 . The composite resin Filtek Z-250 was applied in four 1 mm increments with the aid of a square, condensation silicon, 5 mm x 5 mm matrix, and polymerized by either of light sources for 40 s. Scotchbond Multipurpose Plus polymerized by halogen light presented the highest bond strength values (39.69 ± 7.07 MPa), and the other groups did not present statistically significant differences: Scotchbond Multipurpose Plus polymerized by LED (22.28 ± 2.63 MPa), Clearfil SE Bond polymerized by halogen light (27.82 ± 2.65 MPa) and by LED (22.89 ± 5.09 MPa). DESCRIPTORS: Adhesives; Dental bonding; Polymerization; Light-emitting diode (LED). RESUMO:Com a grande busca pelo desenvolvimento das técnicas de polimerização das resinas compostas e dos sistemas adesivos, foram introduzidos no mercado os LEDs. Com base na literatura estudada, neste trabalho é avaliada a força de união da resina composta ao esmalte associado a um sistema adesivo convencional e a um sistema autocondicionante polimerizados por luz halógena e LED, por meio do teste de microtração. Os dentes bovinos foram divididos em 4 grupos com 10 dentes em cada um (n = 10), para aplicação do adesivo Scotchbond Multipurpose Plus (3M-ESPE) e do Clearfil SE Bond (Kuraray) conforme orientação do fabricante, ambos polimerizados por 10 s tanto pela luz halógena (Degulux Soft Start -Degussa Hulls) com potência de 550 mW/cm 2 como pelo LED (Kerr Demetron) com potência de 600 mW/cm 2 . A resina composta Filtek Z-250 foi aplicada em 4 incrementos de 1 mm com auxílio de uma matriz de silicona de condensação de formato quadrado com dimensões de 5 mm x 5 mm; sendo polimerizada tanto pela luz halógena como pelo LED por 40 s. O adesivo Scotchbond Multipurpose Plus polimerizado com luz halógena apresentou os maiores valores de adesão (39,69 ± 7,07 MPa) e os outros grupos não apresentaram diferença estatisticamente significante entre si: Scotchbond Multipurpose Plus polimerizado por LED (22,28 ± 2,63 MPa), Clearfil SE Bond polimerizado por luz halógena (27,82 ± 2,65 MPa) e por LED (22,89 ± 5,09 MPa).
