Effect of Silver Diamine Fluoride on Microtensile Bond Strength to Dentin

Abstract

The aim of this in vitro study was to investigate the effect of the cariostatic and preventive agent silver diamine fluoride (SDF) on the microtensile bond strength of resin composite to dentin. Forty-two caries-free, extracted molars were flattened occlusally and apically using a diamond saw, and the exposed occlusal dentin was polished with a series of silicon carbide papers, all under water irrigation. The teeth were then randomly divided into six groups of seven teeth each that were treated as follows: 1) Peak SE self-etch bonding agent; 2) 12% SDF + Peak SE; 3) 38% SDF + Peak SE; 4) Peak LC etch-and-rinse bonding agent; 5) 12% SDF + Peak LC; and 6) 38% SDF + Peak LC. Four-millimeter buildups of Amelogen Plus were incrementally placed on all teeth; after a 24-hour storage period in distilled water, the specimens were sectioned perpendicular to the adhesive interface to produce beams of cross-sectional surface area measuring approximately 1 mm(2). The beams were placed on a microtensile testing machine, which utilized a single-speed pump motor and force gauge at 20 kgf × 0.01 second to record maximum tensile force before failure occurred. Two-way analysis of variance and post hoc Tukey tests were performed to compare the effects of the SDF on microtensile bond strength, with statistical significance set at α = 0.05. None of the experimental groups treated with different concentrations of SDF showed a significant difference in bond strength compared to the control groups, and there was no significant difference in bond strength between self-etch and etch-and-rinse groups. However, the effect of SDF on self-etch bonded teeth compared to etch-and-rinse bonded teeth was statistically significant (p=0.0363), specifically at the 12% concentration. SDF does not adversely affect the bond strength of resin composite to noncarious dentin.

Effect of silver diamine fluoride and potassium iodide on shear bond strength of glass ionomer cements to caries-affected dentine

“…The traditional approach of managing cavitated carious lesions is to drill and fill, which refers to mechanically removing the soft and bacteria‐infected dentine before filling the cavity with a proper restorative material. It is still reasonable to conduct the excavation because infected dentine is highly demineralised and physiologically not remineralisable based on the current evidence. Nevertheless, there is evidence showing that removal of soft carious lesions may not be necessary.…”

“…Dental caries, defined as a localised, pathological process with multiple factors, softening dental hard tissues and proceeding to the formation of cavities, continues to be a prevalent disease all over the world. In recent years, the development of restorative materials and advancement in our conception of the caries process have created the capability to practice in consideration of a minimally invasive dentistry philosophy. It requires performing management with as little tissue loss as possible and without causing any destruction to the adjacent healthy tooth tissues.…”

Effect of Silver Diamine Fluoride and Potassium Iodide Treatment on Secondary Caries Prevention and Tooth Discolouration in Cervical Glass Ionomer Cement Restoration

“…Clinical studies also showed the success of SDF in preventing and arresting dental caries [11,12]. A laboratory study found that the bond strength of restorations to dentine was not adversely affected by SDF using resin-based adhesives [13]. The application of SDF under GIC restorations has been demonstrated to produce a promising pulpal response and be effective in facilitating the formation of reparative dentine [14].…”

Dentin hydraulic conductance with different application times of diamine silver fluoride/potassium iodide desensitizing solution

“…With this result, it can be concluded that it is preferable to use an adhesive with an etching technique and rinsing instead of one self-etch prior to treatment with diamine silver fluoride. [8] Regarding effects on the resistance of tooth bond restoration, Knight et al conducted an in-vitro study in order to compare the strength of adhesion of glass ionomer cement on dentin surfaces. Tooth surfaces were treated with diamine silver fluoride/iodide of potassium and compared to untreated dentin.…”
