“…The bond strengths of the two self-etch adhesive systems to both NCAD and ACAD were significantly lower than that to normal dentin, in line with previous reports 6,9,19,20) . It was suggested that the mechanical properties of caries-affected dentin which relate to the mineral content play the key role in bond strength to the substrate 9) .…”

“…Moreover, additional etching which could remove these mineral deposits did not improve bonding of CSE to NCAD 20) . Likewise, formation of resin tags following chemomechanical removal of caries did not significantly improve bond strength of self-etch adhesives 19) . In the clinical situation, keeping the tubules sealed may have an advantage in decreasing pain during operation or after that.…”

This study aimed to investigate an artificial caries-affected dentin (ACAD) model for in vitro bonding studies in comparison to natural caries-affected dentin (NCAD) of human teeth. ACAD was created over 7 days in a demineralizing solution. Mineral density (MD) at different depth levels (0-150 µm) was compared between NCAD and ACAD by transverse microradiography. Micro-tensile bond strengths (µTBS) of two two-step self-etch adhesives to sound dentin, NCAD and ACAD were evaluated. Caries-affected dentin type was not a significant factor when comparing MD at different lesion levels (p>0.05). Under SEM, the dentinal tubules appeared occluded with crystal logs 1-2 µm in thickness in the NCAD; whereas they remained open in the ACAD. The µTBS to caries-affected dentin was lower than sound dentin, but was not affected by the type of caries (p>0.05). In spite of their different morphologies, the ACAD model showed similar MD and µTBS compared to NCAD.

“…In the present study, there was no difference between the use of bur and Carisolv ® system on the bond strength of the different adhesive systems tested. This finding was in agreement with Sonoda et al, 18 Banerjee et al 23 and Heng li et al 24 Sonoda et al described the role of NaOCl in Carisolv ® in maintaining or even increasing the bond strength in caries affected dentine. 18 The authors, on the basis of a previous study, 25 suggested that application of NaOCl affect the dental collagen, influencing the infiltration of resin monomers.…”

The effect of caries excavation methods on the bond strength of etch-and-rinse and self-etch adhesives to caries affected dentine

et al. 2013

Background: The aim of this study was to evaluate the influence of chemomechanical caries removal and conventional caries excavation on the microtensile bond strength of three different dentine adhesive systems. Methods: Thirty extracted human mandibular molars with radiographic signs of dental caries extending up to the middle third of dentine were sectioned longitudinally through the centre of the carious lesion in a buccolingual direction to yield two sections. One half of each tooth was excavated by tungsten carbide bur and the other half was chemomechanically treated with Carisolv ® . Three dentine bonding systems: an etch-and-rinse single bottle adhesive (Single Bond, 3M ESPE); a two bottle, two-step self-etch bonding system (One Coat Self Etching Bond, Coltene Whaledent); and a single-step, single bottle self-etch adhesive (Adper Easy Bond Self-Etch Adhesive, 3M ESPE) were applied and composite build-up was done. The specimens were tested for microtensile bond strength. Data were analysed using two-way analysis of variance and pair-wise multiple comparisons were done using the Holm-Sidak method. Results: The etch-and-rinse adhesive and two bottle self-etch system showed significantly higher bond strength than the single bottle self-etch system. Caries excavation method had no influence on bond strength values. Conclusions: Carisolv ® did not affect the microtensile bond strength values of different adhesive systems tested to the caries affected dentine.

“…To assure long-term success to restorations placed on sound dentin or caries-altered dentin, the adhesive systems with improved marginal sealing capability and stable adhesion to tooth over time are critical (22). The etch-and-rinse adhesive systems have been shown to attain better bonding to caries-affected and caries-infected dentin as compared to self-etching systems (2,6,12). However, this trend is not absolute when bonding to sound dentin, since bonding to any dentin can be strongly affected by the chemical composition of adhesives (23).…”

“…The short and long-term bond strengths to cariesinfected and caries-affected dentins commonly present lower values for both substrates, though some of these bond strength values were found to be clinically acceptable, since there is some evidence that macrotensile and microtensile bond strength tests correlates with microtensile and tensilen bond strength tests (5,6,(11)(12)(13). There is a challenge on bonding to caries-affected dentin, since the deposition of acid-resistant minerals at the intratubular regions (3,5,6,14) makes this substrate almost impermeable to water (6).…”

Influence of Different Dentin Substrate (Caries-Affected, Caries-Infected, Sound) on Long-Term μTBS

et al. 2017

The aim of this study was to evaluate the μTBS in different dentin substrates and water-storage periods. Twenty-four dentin blocks obtained from sound third molars were randomly divided into 3 groups: Sound dentin (Sd), Caries-affected dentin (Ca) and Caries-infected dentin (Ci). Dentin blocks from Ca and Ci groups were subjected to artificial caries development (S. mutans biofilm). The softest carious tissue was removed using spherical drills under visual inspection with Caries Detector solution (Ca group). It was considered as Ci (softer and deeply red stained dentin) and Ca (harder and slightly red stained dentin). The Adper Single Bond 2 adhesive system was applied and Z350 composite blocks were built in all groups. Teeth were stored in deionized water for 24 h at 37 ºC and sectioned into beams (1.0 mm 2 section area). The beams from each tooth were randomly divided into three storages periods: 24 h, 6 months or 1 year. Specimens were submitted to µTBS using EZ test machine at a crosshead speed of 1.0 mm/min. Failure mode was examined by SEM. Data from µTBS were submitted to split plot two-way ANOVA and Tukey's HSD tests (α=0.05). The µTBS (MPa) of Sd (41.2) was significantly higher than Ca (32.4) and Ci (27.2), regardless of storage. Ca and Ci after 6 months and 1 year, presented similar µTBS. Mixed and adhesive failures predominated in all groups. The highest µTBS values (48.1±9.1) were found for Sd at 24 h storage. Storage of specimens decreased the µTBS values for all conditions.
