Article Abstract
FCP-COMPLEX is a newly-developed solution that contains fluoride, calcium, and phosphoric acid. It has the potential to reinforce caries-affected dentin. The purpose of this study was to evaluate the effect of FCP-COMPLEX on the morphology of bovine artificial caries-affected dentin (ACAD). FCP-COMPLEX, 2% sodium fluoride solution, and distilled water were applied to bovine ACAD and the effect on acid-induced damage was observed. Scanning electron microscopy was used to evaluate morphology after acid application. Energy dispersive X-ray spectroscopy was used for mapping and quantitative analyses of the dentin surface, and for line analysis of dentin-adhesive interface. The FCP-COMPLEX precipitated on the dentin surface and fluoride, calcium, and phosphorus were detected at a higher level in the FCP-COMPLEX group. The area of acid damage in caries-affected dentin was reduced by FCP-COMPLEX. In conclusion, FCP-COMPLEX significantly increased the deposition of fluoride onto bovine ACAD and inhibited demineralization.

Inhibition of MMP activity and preservation of dentin collagen structure of zinc-releasing glass ionomer cement.
J Dent
September 2025
Department of Cariology and Operative Dentistry, Graduate School of Medical and Dental Sciences, Institute of Science Tokyo, Tokyo, Japan.
Objective: This study evaluated the ability of a novel zinc-releasing glass ionomer cement (GIC), Caredyne Restore (CR), to inhibit matrix metalloproteinase (MMP) activity and preserve dentin collagen integrity, compared with a conventional GIC (Fuji IX, FIX) and chlorhexidine (CHX), a widely used MMP inhibitor.
Methods: Demineralized bovine dentin beams were allocated to four groups: deionized water (negative control), CHX (positive control), FIX eluate, and CR eluate. MMP Activity was assessed before and after treatment using a colorimetric assay.
Elemental and micromorphological analysis of ion releasing restoration/carious dentin interface.

Conservative Dentistry Department, Faculty of Dentistry, Mansoura University, Mansoura, Egypt.
The objective of the current study was to evaluate elemental analysis and micromorphological patterns at the interfaces between tooth substrates either sound or demineralized dentin and ion-releasing restorations, including conventional glass ionomer and ion-releasing composite. The evaluation was conducted immediately (after 24 h) and after six months of artificial saliva storage. A total of 48 sound human premolars were used in this study.

To investigate the efficacy of diode laser (DL), photodynamic therapy (PDT), and ozone water on the removal of smear layer (SL) and its assessment via scanning electron microscope (SEM) following its effect on shear bond strength (SBS) on carious affected dentin. Sixty-six caries-affected dentin (CAD) samples were obtained from the dental outpatient department. The occlusal enamel and infected dentin of the included samples were meticulously excised using a water-cooled, slow-speed device, resulting in a flat mid-coronal CAD surface.

Objectives: To evaluate the remineralizing potential of biomimetic analogs applied to caries-affected dentin (CAD) using the simulated body fluid (SBF) and a remineralization solution as Ca and PO ions sources.
Methods: Flat dentin surfaces from caries-free molars (N = 111) were subjected to a biological protocol (Streptococcus mutans) to induce dentin caries in vitro. The mineral and organic content of sound (SD), infected (ID), CAD, and CAD etched with phosphoric acid (CAD-PA) were determined to validate the protocol.
Bond strength durability of three bioactive restorative materials to silver diamine fluoride treated artificially demineralized dentine.

Background: This study aimed to assess the impact of 38% silver diamine fluoride (SDF) treatment regarding microtensile bond strength of three bioactive restorative materials to artificially induced caries-affected dentine after thermocycling; Alkasite restorative material, Glass hybrid restorative (GHR) and Resin modified glass ionomer (RMGI).
Methods: A total of 60 artificially demineralized human mid-coronal dentine specimens were randomly allocated into two main groups (n = 30 each): a control group and an SDF-treated group (38% SDF). Each group was additionally split into three subgroups (n = 10) regarding the type of restorative material (Alkasite; Cention N, GHR; EQUIA Forte fil, RMGIC; Fuji II LC).
