“…Even though enamel is the first anatomic barrier exposed to acid challenge, and therefore subject to an erosion phenomenon, the majority of primary studies focused on dentin. In fact, the latter is commonly affected by erosion and evidence tells us that adhesion remains a challenge when held in dentin [ 21 , 32 , 44 , 56 ]. Moreover, most cavity preparations involve dentin, hence the need for evidence that can guide clinical in this substrate.…”

“…While CHX or benzalkonium chloride (BAC) showed that proteolytic inhibitors may not improve the durability of bond strength, other agents showed encouraging immediate bond strength results. In fact, cross-linking agents like proanthrocyanidins (PAA) and riboflavin (RFV) contributed to stabilize the collagen mesh, resulting in promotion of monomer infiltration, ultimately altering the bonding and nanomechanical properties of eroded dentin [ 32 ].…”

“…This reinforces the idea that the disparity of experimental conditions leads to conflicting results. Also, other authors operated with soft drinks such as Coca-Cola [ 13 , 32 , 35 , 42 , 44 , 51 , 53 , 54 , 56 , 59 ] or Sprite [ 49 , 52 ]. Some also used orange juice to simulate the effects of citric acid [ 47 , 50 ], while others chose hydrochloric acid.…”

“…Regarding bond strength tests, the preferred setup was the microtensile bond strength test [ 13 , 32 , 36 , 38–43 , 46–48 , 50 , 51 , 54 , 55 , 57 , 58 ]. Most authors chose this type of test mainly because it is highly reproducible, useful for material screening and has good clinical translation.…”

Aim To summarize and report laboratory studies of adhesion in eroded substrates, which used bond strength as an outcome measure. To determine the strategies available to overcome bonding difficulties, the quality and consistency of the methodology and to find evidence gaps. Materials and Methods The present review followed PRISMA-ScR guidelines. A search was conducted on PubMed/Medline, Scopus and EMBASE (Ovid) databases to identify published peer-reviewed papers (2010–2020). For final qualitative synthesis, 29 articles were selected which respected the inclusion criteria. Data charting was carried out, independently, by two reviewers and quality assessment of the articles was performed. Results The primary studies included fall into four major categories: comparison of restorative materials and application modes, enzymatic inhibitors, surface pretreatments or remineralization strategies. Most studies found evaluated dentin (76%), while 17% evaluated enamel, and 7% evaluated both substrates. The majority of the studies reported an effective intervention (83%). Bond strength to eroded dentin is significantly reduced, while in enamel erosion is beneficial. The bond strength to eroded dentin is material-dependent and favored in systems containing 10-MDP. Great disparities among the erosion models used were found, with citric acid in different concentrations being the preferred method, although standardization is lacking. Conclusions Adhesives containing 10-MDP show beneficial results in eroded dentin, and surface preparation methods should be considered. Studies which evaluated adhesion to eroded enamel/dentin show high heterogeneity in what concerns aims and methodology. Strategies that focus on remineralizing dentin and strategies to protect bond longevity in this substrate require further research.

Investigating a Commercial Functional Adhesive with 12-MDPB and Reactive Filler to Strengthen the Adhesive Interface in Eroded Dentin

To compare the adhesive interface of eroded dentin formed by a functional dental adhesive and a gold standard strategy, by testing microtensile bond strength (μTBS), hardness/elastic modulus. Permanent sound human molars were randomly allocated to four experimental groups, all subject to artificial erosion (0.05 M citric acid; 3× daily, 5 days). Groups included control Clearfil SE Bond 2 (CFSE), and experimental group Clearfil SE Protect (CFP), at two different time points-immediate (24 h) and long term (3 months–3 M). Samples were sectioned into microspecimens for μTBS (n = 8) and into 2-mm thick slabs for nanoindentation assays (n = 3). Groups CFSE_3M and CFP_3M were stored in artificial saliva. Statistical analysis included two-way ANOVA for μTBS data, while hardness/modulus results were analyzed using Kruskal–Wallis H Test (significance level of 5%; SPSS v.27.0). Although no significant differences were found between mean μTBS values, for different adhesives and time points (p > 0.05), a positive trend, with μTBS rising in the CFP_3M group, was observed. Regarding hardness, no significant differences were seen in the hybrid layer, considering the two variables (p > 0.05), while the reduced elastic modulus rose in CFP_3M when compared to 24 h. Thus, CFP shows similar mechanical and adhesive performance to CFSE in eroded dentin, although it may comprise promising long-term results. This is advantageous in eroded substrates due to their increased enzymatic activity and need for remineralization.
