Influence of EDC on Dentin-Resin Shear Bond Strength and Demineralized Dentin Thermal Properties

Abstract

This study aimed to evaluate the bonding strength and thermal properties of demineralized dentin with and without EDC treatment. Sound human molars were randomly divided into seven treatment groups (n = 20): control, 80% ethanol, and five EDC ethanol solutions (0.01–1.0 M). In each group, 16 samples were used for bond strength assessment and 4 samples were used for scanning electron microscopy (SEM) analysis. A further 70 intact molars were used to obtain a fine demineralized dentin powder, treated with the same solutions and were evaluated the crosslink degree by ninhydrin test and denaturation temperature (Td) by differential scanning calorimetry. EDC-treated specimens (<1.0 M) had a higher bond strength, especially 0.3 and 0.5 M group, than the control counterpart. There was a significant drop in bond strength of 1.0 M EDC group. SEM revealed a homogeneous and regular interface under all treatments. EDC treatment significantly increased the demineralized dentin cross-link degree and Td compared with the control and ethanol treatments. The 0.3 and 0.5 M treatments showed the highest cross-link degree and Td. In terms of mechnical and theramal properties consideration, 0.3 and 0.5 M EDC solutions may be favorable for when applied with etch-and-rinse adhesives, but it is still needed further long-term study.

Effect of Collagen Crosslinkers on Dentin Bond Strength of Adhesive Systems: A Systematic Review and Meta-Analysis

“…A total of 50 articles were included in the qualitative analysis. Of these, 5 articles were not considered for the meta-analysis because two of them did not express the BS data as means and SDs [ 76 , 77 ], and in 3 articles the number of specimens used could not be retrieved [ 78 , 79 , 80 ], totalling 45 articles considered for the quantitative analysis [ 17 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 , 124 , 125 ]. A flowchart designating the study selection process according to the PRISMA statement is presented in Figure 1 .…”

The influence of acid etching or chitosan dentin surface treatments on dentin wettability and shear bond strength of self- etch adhesives

“…Shear bond strength (SBS) is a mechanical test of the adhesive interphase that can provide an indication of the bond integrity between esthetic restorations and dentin surface. Reliable results were achieved in previous researches studying dentin-adhesives interphase (12)(13)(14)(15)(16)(17)(18)(19) .…”

Effect of pretreatment with matrix metalloproteinase inhibitors on the durability of bond strength of fiber posts to radicular dentin

“…Shafiei, Yousefipour et al (2016) reported that the EDC could diminish the effect of aging on the bond strength of fiber posts to radicular dentin using three types of resin cement. The demineralized dentin cross‐link degree was shown to increase by EDC compared with control and ethanol treatments in a study by Tang et al (2016). In agreement with the current study, Comba et al (2019) reported that the application of EDC did not cause a significant change in bond strength of adhesive‐cemented fiber posts after 24 h; however, it maintained the bond strength after 1 year of storage in artificial saliva, compared with the controls.…”

“…The effect of CHX on bond strength is still a matter of debate. Little attention has been paid to the beneficial effects of EDC on dentin bond durability, and a clear protocol of EDC dentin surface coating is still under investigation (Shafiei, Yousefipour et al, 2016;Tang et al, 2016). Shafiei, Yousefipour et al (2016) reported that the EDC could diminish the effect of aging on the bond strength of fiber posts to radicular dentin using three types of resin cement.…”

“…It has been proposed that activation of carboxylic groups and cross‐linking of collagen fibrils by EDC preserve the dentin–resin bond mechanical properties (Liu et al, 2011; Tezvergil‐Mutluay et al, 2012). Various EDC solutions have been investigated to find a protocol of EDC dentin surface coating that best improves the bond strength over time; however, little attention has been paid to radicular dentin (Mazzoni, Angeloni et al, 2013; Mazzoni et al, 2018; Saffarpour et al, 2020; Tang et al, 2016).…”
