“…In addition, stronger silicon signals were detected in dentin after immediate treatment (5.5 weight%), which remained at a similar percentage at the 5-day evaluation (5.8 weight%). Given the organic phase in dentin (30 vol%, mainly type I collagen) [ 31 ], the combination of fluoride–silicon-rich toothpaste and calcium booster appears to allow interactions between the negatively charged surface of SiO 2 (–SiOH 2+ , –SiOH, –SiO) and positively charge-carried collagen, which is pH-dependent [ 32 ]. Electrostatic interactions, hydrogen bonding, and complexation all play a role in these interactions [ 33 ].…”

Calcium boosters have been used as a supplement for fluoride toothpastes to repair the dental tissues and reduce dentin permeability. This in vitro study aimed to characterize the regenerative and protective effects of the treatment of dental tissues with a fluoride–silicon-rich toothpaste associated with a calcium booster. Bovine enamel and dentin blocks (n = 5) were obtained (4 × 4 × 6 mm). A fluoride–silicon-rich toothpaste and a calcium booster were used to brush the enamel and dentin both immediately and five days afterwards. The outcomes were then compared to those of the untreated control group. After that, the specimens were cross-sectioned. SEM was used to evaluate the micromorphology of the surface and cross-section. Energy-dispersive X-ray spectroscopy (EDS) was used to determine the elemental analyses (weight%). After treatment for 5 days with a booster/silicon-rich toothpaste, EDS analysis demonstrated that it induced a significant mineral change. It was also able to form a protective silicon-enriched mineral layer on both enamel and dentin surfaces. It was demonstrated in vitro that a fluoride–silicon-rich toothpaste associated with a calcium booster regenerates the dental tissues, remineralizing the enamel structure and occluding the dentin tubules.

“…Bonding to gingival dentin walls is generally less effective than bonding to axial walls and might not be sufficient to resist interfacial polymerization contraction stresses. Adhesive bond strength studies combining in vivo insertion with in vitro testing indicate a greater incidence of debonding at gingival walls of composite resin restorations [ 11 , 77 , 78 ]. The greatest risk of recurrent caries is at the gingival margins of restorations, irrespective of the kind of restoration.…”

“…Furthermore, it complicates the insertion of direct restorations and appropriate impression taking (traditional or optical) and the delivery of indirect restorations. The imprecision of the restoration’s subgingival margin leads to more biofilm accumulation, gingival and periodontal inflammation, and an increased risk of RC [ 11 , 77 , 78 , 183 ].…”

This review addresses the rationale of recurrent and/or residual caries associated with resin composite restorations alongside current strategies and evidence-based recommendations to arrest residual caries and restrain recurrent caries. The PubMed and MEDLINE databases were searched for composite-associated recurrent/residual caries focusing on predisposing factors related to materials and operator’s skills; patient-related factors were out of scope. Recurrent caries and fractures are the main reasons for the failure of resin composites. Recurrent and residual caries are evaluated differently with no exact distinguishment, especially for wall lesions. Recurrent caries correlates to patient factors, the operator’s skills of cavity preparation, and material selection and insertion. Material-related factors are significant. Strong evidence validates the minimally invasive management of deep caries, with concerns regarding residual infected dentin. Promising technologies promote resin composites with antibacterial and remineralizing potentials. Insertion techniques influence adaptation, marginal seal, and proximal contact tightness. A reliable diagnostic method for recurrent or residual caries is urgently required. Ongoing endeavors cannot eliminate recurrent caries or precisely validate residual caries. The operator’s responsibility to precisely diagnose original caries and remaining tooth structure, consider oral environmental conditions, accurately prepare cavities, and select and apply restorative materials are integral aspects. Recurrent caries around composites requires a triad of attention where the operator’s skills are cornerstones.

“…Since it is a plasmaderived fluid, it also contains inflammatory mediators including cytokines, chemokines, and defensins [16] . The amount of dentinal fluid differs by depth, and the dentin close to the pulp contains more fluid compared to the superficial dentin [17] . Exposure of the pulp-dentin complex causes an outward flow of the dentinal fluid, thereby protecting the pulp.…”

The objective of this mini review is to evaluate the age-related changes in dentin and its effect on bonding. Background: Bonding to dentin poses a great challenge which can be attributed to multifarious including factors such as the high organic content of dentin, the presence of dentinal tubules, a continuously moist environment due to fluid presence in the tubules, permeability in dentin, and intratubular pressure. The bonding becomes more challenging with advancing age due to corresponding age-related changes. This dental problem triggered by age-related changes is mainly attributed to the mineralization property of dentin. The bonding to dentin differs significantly in both primary and secondary dentin. These differences can be maintained by altering the etching time.
