“…The use of a slurry containing particles of set MTA cement on acid-etched dentin, prior to adhesive application, was shown to increase the percentage of continuous margin at the gingival wall of class II restorations after six months in PBS under simulated pulpal pressure, in relation to the control (respectively, 69% and 47%). Samples observed under the scanning electron microscope showed gaps predominantly between the hybrid layer and dentin and particles were identified inside the dentin tubules in groups treated with the MTA particle suspension 26) .…”

Protecting resin-dentin interfaces from hydrolytic and enzymatic degradation is critical for the longevity of adhesive restorations. In recent years, several strategies have been tested in vitro to induce apatite precipitation within interfibrillar and intrafibrillar collagen spaces, as well as in resin-sparse regions where the adhesive infiltration was incomplete. Also, the presence of calcium ions and other metallic ions has shown an inhibitory effect on enzymatic activity. Ion-releasing particles and biomimetic analogs have been studied for hybrid layer remineralization. Overall, remineralization strategy is dependent on the remaining mineral content. In partially demineralized dentin, residual apatite crystallites serve as nucleation sites for calcium and phosphate ions precipitation and crystal growth ("top-down" remineralization). In completely demineralized dentin where crystallites are absent (e.g., acid etched dentin) the use of mineral nano-precursors assisted by non-collagenous proteins analogs are necessary ("bottom-up" remineralization). This article reviews the approaches for hybrid layer remineralization and resin-dentin interface preservation.

“…It is important to define the interdiffusion layer, also called HL, which forms between the adhesive resin and the demineralized dentin, hence, playing a noteworthy role on the retention of the restoration [ 57 , 58 , 59 ]. This HL was not stable with time due to the degradation process [ 60 ].…”

Immediate dentin sealing (IDS) involves applying an adhesive system to dentin directly after tooth preparation, before impression. This was considered an alternate to delayed dentin sealing (DDS), a technique in which hybridization is performed following the provisional phase and just before the indirect restoration luting procedure. This study aimed to compare the bond strength of restorations to dentin of the IDS and the DDS techniques throughout a systematic review and meta-analysis. The following PICOS framework was used: population, indirect restorations; intervention, IDS; control, DDS; outcomes, bond strength; and study design, in vitro studies. PubMed (MedLine), The Cochrane Library, ISI Web of Science, Scielo, Scopus, and Embase were screened up to January 2022 by two reviewers (L.H. and R.B.). In vitro papers studying the bond strength to human dentin of the IDS technique compared to the DDS technique were considered. Meta-analyses were carried out by using a software program (Review Manager v5.4.1; The Cochrane Collaboration). Comparisons were made by considering the adhesive used for bonding (two-step etch-and-rinse, three step etch-and-rinse, one-step self-etch, two-step self-etch, and universal adhesives). A total of 3717 papers were retrieved in all databases. After full-text assessment, 22 potentially eligible studies were examined for qualitative analysis, leaving a total of 21 articles for the meta-analysis. For the immediate bond strength, regardless of the adhesive strategy used, the IDS technique improved the bond strength of restorations to the dentin (p < 0.001). Taking into account the subgroup analysis, it seems that the use of the IDS technique with a two-step etch-and-rinse or a one-step self-etch adhesive system does not represent any advantage over the DDS technique (p = 0.07, p = 0.15). On the other hand, for the aged bond strength, regardless of the adhesive strategy used, the IDS technique improved the bond strength of restorations to the dentin (p = 0.001). The subgroups analysis shows that this improvement is observed only when a three-step etch-and-rinse adhesive system (p < 0.001) or when a combination of an adhesive system plus a layer of flowable resin (p = 0.01) is used. The in vitro evidence suggests that the use of the IDS technique improves the bond strength of dentin to resin-based restorations regardless of the adhesive strategy used. The use of a three-step etch-and-rinse adhesive system or the combination of an adhesive system plus a layer of flowable resin seems to considerably enhance the bond strength in the long term.

“…The hybrid layer plays a significant role in dentin adhesion. It is defined by an interlock consisting of demineralized collagen, residual water, resin, and hydroxyapatite crystals when the resin diffuses through the dentinal tubules (Aggarwal & Bhasin, 2018). The hybrid layer is not stable in the liquid medium; the demineralized collagen matrix is dispersed and the resin matrix is hydrolyzed eventually due to water sorption.…”

The purpose of this in vitro study was to evaluate the effect of immediate dentin sealing (IDS) with and without chlorhexidine (CHX) pretreatment on the shear bond strength (SBS) of dual-cure adhesive resin cement. Mid-coronal dentin surfaces were obtained from 75 human molars. They were randomly allocated into five groups in accordance to type of IDS [etch&rinse/ER (Adper Single Bond2) and universal/U adhesive systems (Single Bond Universal)] and presence of CHX application (n = 15): Group ER; Group ER + CHX; Group U; Group U + CHX; and Group C (no IDS). Dualcure adhesive resin cements were bonded with a cylinder-shaped Teflon mold. The SBS was measured using a universal test machine. Fracture type was evaluated with stereomicroscope. The resin/dentin interfaces were examined with an environmental scanning electron microscope. Data were statistically analyzed with two-way analysis of variance and Bonferroni tests (p < .05). Regarding the IDS treatment groups with/ without CHX, there were no significant differences in SBS (p > .05). Group U + CHX showed significantly higher SBS than Group C (p < .05). Regarding the presence of CHX, no significant differences in SBS were found (p > .05). The prevalent failure mode was the mixed type for most of the groups. Group C exhibited an intact and regular hybrid layer with no resin tag, whereas longer and clear resin-tag formation was visible for Group U + CHX. CHX pretreatment improved the bond strength between adhesive resin cement and dentin when IDS treatment was performed with a universal adhesive system.
