Influence of FCP-COMPLEX on bond strength and the adhesive–artificial caries-affected dentin interface

Abstract

FCP-COMPLEX is a newly developed solution containing fluoride, calcium, and phosphoric acid that has the potential to reinforce caries-affected dentin. This study evaluated the effect of FCP-COMPLEX on micro-tensile bond strength (µTBS) and acid-challenge at the dentin-adhesive interface. FCP-COMPLEX, 2% NaF, and distilled water were applied to artificial caries-affected dentin (ACAD) and the effect on acid-induced damage after resin composite restoration was observed. Scanning electron microscopy and X-ray absorption fine structure (XAFS) were used to evaluate tooth morphology. The µTBS test revealed no effect of FCP-COMPLEX either immediately or after 3 months' storage. The area of acid damage in caries-affected dentin was reduced by FCP-COMPLEX. XAFS analysis revealed that absorbed fluorine on the surface would form CaF2. In conclusion, FCP-COMPLEX significantly reduced the damage of acidic attack at the ACAD-adhesive interface, while the µTBS value was maintained after storage.

Evaluation of experimental calcium-containing primer in adhesive system on micro-tensile bond strength and acid resistance

“…Therefore, the mean bond strength was analyzed by two-way analysis of variance and Dunnett's T3 test. In addition, the mode of failure of debonded specimens was evaluated under scanning electron microscopy (SEM; JSM-5310LV, JEOL, Tokyo, Japan) and classified into one of four categories: 1) cohesive failure in resin or mixed failure between resin and adhesive; 2) interfacial failure between adhesive and dentin; 3) mixed failure between adhesive and dentin; and 4) cohesive failure in dentin 15) . The frequency of failure mode was analyzed with the Fisher exact test.…”

Does surface treatment of demineralized dentin impact on shear bond strength?

“…[6][7][8] On the other hand, a few specialists accept that the utilization of calcium-phosphor syntheses, for example, CPP-ACP containing paste on demineralized dentin may improve bond strength by components, for example, connection with MDP monomers of cements or expanding pH. [9,10] All things considered, restricted examinations have assessed the result of the synchronous use of Er: YAG laser illumination and CPP-ACP containing paste application on bond solidarity to demineralized dentin. Along these lines, our point in this in vitro study was to research the impact of Er: YAG laser radiation and the utilization of CPP-ACP containing paste (MI Paste) on the shear bond strength of universal adhesives with self-etch mode to demineralized dentin…”

Effect of casein phosphopeptide-amorphous calcium phosphate and erbium:Yttrium–Aluminium–Garnet laser on shear bond strength to demineralized dentin

“…[8][9][10] Furthermore, some researchers believe that the application of calcium-phosphor compositions such as casein phosphopeptideamorphous calcium phosphate (CPP-ACP)-containing paste demineralized dentin may improve bond strength by mechanisms such as interaction with MDP monomers of adhesives or increasing pH. [11,12] Nevertheless, limited studies have evaluated the effect of the simultaneous use of erbium:yttrium-aluminumgarnet (Er:YAG) laser irradiation and CPP-ACP-containing paste application on bond strength to demineralized dentin. On the other hand, fifth-generation etch-and-rinse (E and R) adhesives are still among the most common types of adhesives in the commercial market.…”
