“…Even though several researches have assessed the deterioration of resindentin bonds in permanent teeth, information re- garding their bonding stability to primary dentin is still limited. 15,[18][19][20] In fact, degradation of resin-dentin bonds was observed in the current study, represented by a decrease in µTBS values after 6 months of water storage, as observed in previous studies. 20,21 However, the reduction in bond strength was more pronounced for permanent dentin.…”

“…22,23 Likewise, the use of metalloproteinase inhibitors, as chlorhexidine digluconate, does not negatively influence the immediate bond strength and prevents, or least decelerates the deterioration of resin-dentin bonds in primary 19,20 and permanent teeth. 24,25 Since only one property of the adhesive systems was evaluated in the current study, further researches evaluating other bonding properties and different adhesive bonding approaches should be conducted to elucidate the durability of resin-dentin interfaces in primary teeth.…”

Degradation of resin-dentin bonds of etch-and-rinse adhesive system to primary and permanent teeth

2012

The aim of this in vitro study was to compare the degradation of resin-dentin bonds of an etch-and-rinse adhesive system to primary and permanent teeth. Flat superficial coronal dentin surfaces from 5 primary second molars and 5 permanent third molars were etched with phosphoric acid and bonded with an adhesive system (Adper Single Bond 2, 3M ESPE). Blocks of resin composite (Z250, 3M ESPE) were built up and the teeth sectioned to produce bonded sticks with a 0.8 mm 2 crosssectional area. The sticks of each tooth were randomly divided and assigned to be subjected to microtensile testing immediately (24 h) or after aging by water storage (6 months). Data were analyzed by two-way repeated measures ANOVA and Tukey post hoc test (α = 0.05). Failure mode was evaluated using a stereomicroscope (400×). Microtensile values significantly decreased after the 6 months aging, independent of the dentin substrate. In 24 h, the values obtained to primary dentin were lower compared with permanent dentin. This difference was not maintained after aging. Adhesive/mixed failure was predominant in all experimental groups. In conclusion, degradation of resin-dentin bonds of the etch-and-rinse adhesive system occurred after 6 months of water storage; however, the reduction in bond strength values was higher for permanent teeth.

MMP Inhibitors on Dentin Stability

The aim of this study was to systematically review the literature for in vitro and ex vivo studies that evaluated the effect of matrix metalloproteinase (MMP) inhibitors during the adhesive procedure on the immediate and long-term resin-dentin bond strength. The search was conducted in 6 databases with no publication year or language limits, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. From 1,336 potentially eligible studies, 48 were selected for full-text analysis, and 30 were included for review, with 17 considered in the meta-analysis. Two reviewers independently selected the studies, extracted the data, and assessed the risk of bias. Pooled effect estimates were expressed as the weighted mean difference between groups. The most used MMP inhibitor was chlorhexidine (CHX). Immediate bond strength results showed no difference between 2% CHX and control; however, a difference was found between 0.2% CHX and control at baseline. After aging, CHX presented higher bond strength values compared to control groups (p < .05). However, this was not observed for longer periods of aging. High heterogeneity was found in some comparisons, especially for the water storage aging subgroup. Subgroup analyses showed that self-etching and etch-and-rinse adhesives are benefited by the CHX use. From the studies included, only 1 presented low risk of bias, while the others showed medium or high risk of bias. The use of MMP inhibitors did not affect the immediate bond strength overall, while it influenced the aged bond strength. Aging procedures influenced bond strength values of the dentin adhesion stability.

“…Although bonding to enamel is already well established in literature, the durability between dentin and adhesive systems within hybrid layers may not be that long and stable (Breschi et al, 2008;Leitune et al, 2011;Osorio et al, 2013), and has been shown to be multifactorial in nature. Long-term studies had proved that bond strength of resin-bonded dentin decreased over time due to collagen degradation (De Munck et al, 2003;Koshiro et al, 2004;Breschi et al, 2010).…”

; Lluis Giner 4 BRAVO, C.; SAMPAIO, C. S.; HIRATA, R.; PUPPIN-RONTANI, R. M. ; MAYORAL, J. R. & GINER, LL. Effect of 2 % chlorhexidine on dentin shear bond strength of different adhesive systems: A 6 months evaluation. Int. J. Morphol., 35(3):1140Morphol., 35(3): -1146Morphol., 35(3): , 2017. SUMMARY:This study evaluated the effect of chlorhexidine dentin treatment on shear bond strength (SBS) of adhesive systems after different storages. The work included 144 third molars that had their dentin exposed and were divided in 6 groups: G1 (ASB+CHX: Adper Scotchbond 1XT + chlorhexidine 2 % prior Primer); G2(ASB); G3 (APP+CHX: Adper Prompt L-Pop + CHX); G4(APP); G5 (SBU+CHX: Single Bond Universal + CHX); and G6(SBU). Resin build-up was performed and teeth were subdivided regarding storage times (n=8): 72 h, 3 and 6 months. Next, SBS test was performed. At 72 hours, all equivalent groups (same adhesive system, different dentin treatment) showed no significant difference in SBS (P≥.05). Self-etch adhesive groups (with or without CHX) presented lower SBS compared to other systems (P≤.05). After 3 and 6 months, all CHX-treated groups presented significantly higher SBS compared to equivalent non-treated groups (P≤.05). For both storage times, Single Bond Universal presented the highest SBS values within the same dentin treatment (P≤.05), while Adper Scotchbond and Adper Prompt-L-Pop were not significantly different among them, also within the same dentin treatments [3 months (with CHX: P=.966; without: P=.958) and 6 months (with CHX: P =.887; without: P=.990)]. CHX Dentin disinfection is indicated for all classes of adhesives studied.
