“…Studies have evaluated the bond strength of posts cemented with resin cements, along with a variety of bonding agents, as well as the bond strength of direct core foundation systems to teeth. 7,8 Some focused on chemical incompatibility between bonding agents and resin cements, [8][9][10][11][12] while others emphasized the importance of an adequate polymerization of dual-cured resin cements. 13,14 The results from most studies have demonstrated that the self-curing mechanism is not as effective as the light-curing one.…”

This study evaluated the Knoop Hardness (KHN) values of two dual-cured composite resin core build-up materials and one resin cement exposed to different curing conditions. Two dual-cured core buildup composite resins (LuxaCore  -Dual, DMG; and FluoroCore  2, Dentsply Caulk), and one dual-cured resin cement (Rely X ARC, 3M ESPE) were used in the present study. The composite materials were placed into a cylindrical matrix (2 mm in height and 3 mm in diameter), and the specimens thus produced were either light-activated for 40 s (Optilux 501, Demetron Kerr) or were allowed to self-cure for 10 min in the dark (n = 5). All specimens were then stored in humidity at 37°C for 24 h in the dark and were subjected to KHN analysis. The results were submitted to 2-way ANOVA and Tukey's post-hoc test at a pre-set alpha of 5%. All the light-activated groups exhibited higher KHN values than the self-cured ones (p = 0.00001), regardless of product. Among the self-cured groups, both composite resin core build-up materials showed higher KHN values than the dual-cured resin cement (p = 0.00001). LuxaCore  -Dual exhibited higher KHN values than FluoroCore  2 (p = 0.00001) when they were allowed to self-cure, while no significant differences in KHN values were observed among the light-activated products. The results suggest that dual-cured composite resin core build-up materials may be more reliable than dual-cured resin cements when curing light is not available.

“…4,7,9 The literature has reported that there is an inverse relationship between the acidity of these 1-bottle adhesives and the bond strength obtained from the use of self-cured composites. 2,8 According to this study, the positive correlation between acidity and microleakage could be attributed to the acid-base reaction between the acidic monomers in the oxygen inhibited layer and the tertiary amines from the self-cured composites, since these amines, in association with benzoyl peroxide, are responsible for the polymerization process.…”

“…8 However, clinicians have reported bonding failures when self-cured composite core materials were bonded with 1-bottle light-cured adhesive systems. 2,9 The decrease in bond strength of self-cured composites to dentin was inversely proportional to the acidity of these 1-bottle systems. 10 Adverse chemical interactions between unpolymerized acidic adhesive resin monomers and a basic tertiary amine catalyst in the composite was thought to be responsible for the observed incompatibility.…”

“…Even if mechanical retentions were incorporated, the resultant microleakage would predispose such core buildups to early failure. 9 In addition, the relationship between bond strength and microleakage is not clearly understood, and a significant number of studies have failed to demonstrate a relationship between bond strength and microleakage. [12][13][14] Little is known about the effect of the acidity of 1-bottle light-cured adhesives on the microleakage of selfcured composites.…”

SUMMARYThis in vitro study examined the effect of 1-bottle light-cured adhesives with different acidities on the microleakage of a self-cured composite in Class II restorations. Forty-five Class II cavities were prepared on the proximal surfaces of extracted human intact third molars that were randomly assigned to 3 groups (15 cavities in each group). The following adhesives were applied according to the manufacturer's instructions: Single Bond (Group 1), Excite (Group 2) and One-Step (Group 3). The teeth were restored with a combination of a self-cured resin composite (Concise) and a light-cured resin composite (Filtek P60). After thermocycling (500 cycles at 5°C/55°C) and immersion in 2% basic Fushin, the teeth were sectioned and evaluated for microleakage using a stereomicroscope (16x). Microleakage was scored on a scale of 0 to 3. Kruskal-Wallis analysis showed that there was a significant difference in microleakage values of 3 adhesives with a self-cured composite, and low pH may have contributed to high microleakage values. Also, 2 by 2 comparisons with the MannWhitney U-test revealed a significant difference at the p<0.05 level between Groups 1 and 2 and between Groups 2 and 3. However, there was no statistically significant difference between Groups 1 and 3.

“…Hagge and Lindemuth 15 reported that Clearfil SE Bond showed higher shear bond strength than Single Bond in coronal dentin substrate. The higher bond strength of Clearfil SE Bond compared to "one-bottle" dentin bonding agents (Prime & Bond 2.1 and One Coat Bond) in normal and caries-affected coronal dentin was reported by Sengun and others.…”

This study compared the bond strength of two resin cements to human root dentin when used with three bonding agents. The materials used were Rely X ARC and Perma Cem, two one-bottle bonding agents (Single Bond, Bond-1) and one self-etching bonding agent (Clearfil SE Bond).The dentin was obtained from single rooted human teeth, and the specimens were treated with either 15% EDTA or 37% phosphoric acid to remove the smear layer, except in groups where the self-etching bonding agent was used. The resin cements were placed on dentin surfaces with the use of bonding agents. Shear bond strength (SBS) was tested using a single plane shear test assembly.The dentin specimens were divided into 10 groups. Eight groups were pre-treated with EDTA or phosphoric acid to remove the smear layer, followed by a bonding agent (Bond-1 or Single Bond) and resin cement (Rely X or Perma Cem). In the two remaining groups, the smear layer was left intact, and the two resins cements were used in combination with the self-etching bonding agent (Clearfil SE Bond).No statistically significant differences were observed among the eight groups treated with onebottle bonding agents. The mean bond strengths of the two groups treated with the self-etching bonding agent did not differ significantly from each other but were both significantly greater than the bond strengths of all the other groups.The results of this study also showed that EDTA can be used as an alternative to phosphoric acid in bonding procedures for resin cements.
