“…To evaluate the DC of C＝C bonds, spectroscopy methods have been used to determine the DC values because specific vibration bands can be used as internal standards 19) . A common and frequently used method to study the compatibility between an adhesive system and a resin composite is to evaluate the dentin bond strength 20) . Apart from bond strength, degree of conversion also provides additional information about polymerization.…”

The aim of this study was to evaluate the influence of different polymerization modes on degree of conversion and micropush-out bond strength of dual-polymerized resin core systems to dentin by using two different adhesive systems. Two resin core systems, Rebilda DC and Build-It FR, were used in combination with total-etch (Adper Scotchbond Multi-Purpose) and self-etch (Clearfil SE Bond) adhesive systems. After treatment of dentin surfaces, resin core systems were applied into the cavities and subjected to different polymerization modes as follows: (1) chemical polymerization; (2) dual polymerization with standard mode of LED (Elipar FreeLight 2 LED); or (3) dual polymerization with exponential mode of LED. The cavities (n=10 per group) were tested in a universal testing machine. Degree of monomer conversion (DC%) was determined by Fourier transform infrared spectroscopy (n=5 cavities per group). ANOVA revealed that resin core (p=0.002), adhesive system (p<0.001), and polymerization mode (p<0.001) had significant effects on bond strength values. The degree of conversion for resin cores decreased significantly (p<0.001) when only chemical polymerization was employed.

“…In the case of SE and BF, higher indirect light irradiation intensities improved their bonding performance to flat dentin surfaces even when the intensity of the direct light irradiation was relatively low, while for TS, direct and indirect light irradiation intensities had a complementary activity on bonding performance. However, these influences of direct and indirect light irradiation intensities on bonding performance might be different at the cavity walls, because contraction stress induced by light-curing the resin composite causes reduction of bond strength to restricted cavity floor dentin, while for flat surfaces, it is released by free surface area, resulting in less influence on bond strength 31) . Further research is required to pursue the effects of direct and indirect light irradiation on the bonding layer on dentin bonding performance within the cavity and co-polymerization with filled resin composite.…”

This study was designed to evaluate effects of light-irradiated intensities directly and indirectly through resin composites to one-and two-step self-etch adhesives on dentin bonding. One-step (Clearfil S 3 Bond; TS, Bond Force; BF) or two-step (Clearfil SE Bond; SE) self-etch adhesives was applied to dentin surface. The adhesive agent was light-cured with light-intensity of 350 or 600 mW/cm 2 , and then resin composite with different colors (translucent or opaque shade) was filled and light-cured with the same light-intensity as the bonding procedure. After 24 h water storage, bond strengths to dentin were determined using µTBS test. For the 600 and 350 mW/ cm 2 groups, translucent shade resin obtained higher µTBS than opaque shade resin. Using SE and BF, the 350 mW/cm 2 group in translucent shade resin was higher µTBS than the 600 mW/cm 2 group in opaque shade resin, while TS showed no different µTBS between them.

“…In a recent study, no difference in bond strength between a self-cured and a light-cured composite bonded with One-Step to dentin was reported. 18 On the other hand, in PDI curing, the energy density of the initial light-activation (the intensity x exposure time) was not sufficiently effective to initiate a polymerization reaction. 17,19 Thus, during the three-minute waiting period, uncured composite remained in contact with uncured acidic monomer from these adhesives.…”

©Operative Dentistry, 2009, 34-5, 558-564 Clinical RelevanceLow dentin bond strength has been previously documented when one-bottle adhesives are used with self-cured resin-based composites. Low dentin bond strength may also occur when one-bottle adhesives are used with light-cured resin-based composites that are activated by soft-start or pulse-delay curing strategies. F Shafiei • I Safarpoor M Moradmand • AA Alavi SUMMARYThis study examined the effect of different light activation modes for light-cured resin-based composites on the shear bond strength to dentin of two one-bottle adhesives with differing acidity. In this experimental study, a flat middle dentin surface was prepared on 110 extracted sound molars using a 600-grit polish paper. The teeth were then randomly divided into 10 equal groups (n=11). One-Step Plus (OS) and Prime & Bond NT (P&B NT) were used according to the manufacturer's instruction with their respective composite (Aelite, Spectrum TPH) applied and cured using five different light-activation modes: For each of the adhesives, the ranking of SBS was as follows: CO>SSII>PDII>SSI>PDI, with the two-paired comparisons of curing modes being significantly different (p<0.05).The results of the current study indicated that the bond strength of P&B NT might be compromised by the higher acidity of this adhesive compared to OS during each curing mode, especially PDI. The conventional mode was least affected by the acidity of the adhesive.
