Chen X, Inoue G, Fan L, Sekizawa O, Nitta K, Ikeda M, Shimada Y. Enhancement of mineral density and mechanical properties in root caries treated with silver diammine fluoride and glass ionomer cement, with emphasis on silver ion distribution. J Dent 2024; 146:105041. [PMID: 38762076 DOI: 10.1016/j.jdent.2024.105041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/29/2024] [Accepted: 05/03/2024] [Indexed: 05/20/2024] Open
Abstract
OBJECTIVES This study aimed to measure the distribution of silver ion (Ag+), mineral recovery, and nanohardness in carious lesions and comprehensively evaluate the degree of dentin restoration. METHODS Sixty human teeth with root caries were randomly assigned to the control, silver diammine fluoride (SDF) [Safo], and SDF+Glass ionomer cement (GIC) treatment [Safo+Fuji] groups. Micro-computed tomography (micro-CT) was performed at five time points for each sample before/after treatment to evaluate mineral density within and around carious lesions. Three months following treatment, 12 samples were selected for synchrotron radiation X-ray fluorescence analysis to evaluate Ag+ distribution, while 15 samples were selected for nanoindentation. Data were analyzed using Dunnett's T3 test for micro-CT and Wilcoxon rank sum test with Bonferroni correction (p = 0.017) for nanoindentation. The correlation between hardness and mineral change was analyzed using the Spearman rank correlation coefficient. RESULTS The Safo and Safo+Fuji groups showed significantly higher mineral recovery rates than did the control group (p < 0.001). In the Safo group, Ag+ accumulated in the deeper layers rather than the superficial layer of caries. In the Safo+Fuji group, Ag+ was found evenly distributed throughout caries, with only a few Ag+ detected in the GIC layer. Hardness in the Safo+Fuji group was significantly higher compared with the Safo group at depths in the range of 10-50 µm. CONCLUSION In the presence of GICs, SDF exhibited high remineralization capacity when diffusing throughout carious lesions over time. Combined treatment with SDF and GIC could strengthen root dentin even in the presence of caries. CLINICAL SIGNIFICANCE We found that combination treatment with SDF and GIC could increase mineral density in caries and improve the hardness of the tooth structure compared with fluoride-based agents alone. These findings might pave the way for future clinical trials to determine the therapeutic potential of nanotechnology-based restorative materials.

Evaluating the Effect of Silver Diamine Fluoride, with or without Glutathione and Potassium Iodide, on Fluoride Release, Dentin Microhardness and Surface Properties of Dentin. MAEDICA 2024; 19:48-56. [PMID: 38736910 PMCID: PMC11079747 DOI: 10.26574/maedica.2024.19.11.48] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 05/14/2024]
Abstract
This study aimed to evaluate the effect of silver diamine fluoride (SDF) in combination with or without glutathione (Glu) and potassium iodide (KI) on the fluoride release and the enhancement of dentin microhardness. In this et al study, 90 intact premolar teeth from human subjects were allocated into nine groups, each consisting of ten samples: A) control; B) SDF; C) SDF combined with 5% Glu; D) SDF combined with 10% Glu; E) SDF combined with 20% Glu; F) KI after SDF; G) 5% Glu after SDF; H) 10% Glu after SDF; and I) 20% Glu after SDF. Data were analyzed using SPSS version 22 software and ANOVA and post-hoc and repeated measure test (P value <0.05). Dentin microhardness exhibited variations across different treatments, with the highest value being observed in the SDF-5% Glu group and the lowest in the control group. However, there was a significant difference between the mean values of SDF-5% Glu group and the SDF group. Significant increases in microhardness were observed when comparing SDF-5% Glu to SDF+5% Glu and SDF-10% Glu to SDF+10% Glu in peer groups (P value <0.05). Over time, there was a significant increase in the amount of fluoride released as compared to the initial day. The utilization of SDF-5% Glu group exhibited the most favorable effect on improving dentin hardness. Additionally, utilizing Glu in concentrations of 5% and 10% after SDF application proved more effective in increasing dentin microhardness than combining it with SDF. Moreover, in all three fluoride measurement periods, adding 5% Glu to SDF and using 20% Glu following SDF administration led to a significant increase in fluoride release compared to the application of SDF alone.

Abstract
We aim to evaluate the bond strength between resin composite and primary demineralized dentin, pretreated with silver diamine fluoride (SDF) and simultaneous SDF with potassium iodide (KI) after thermal aging. In this in vitro study, human carious-free primary molars were randomly assigned into three groups and prepared by exposing the superficial dentin. The primary dentin of each molar was demineralized. The first group (the control) received saline treatment before bond application. SDF was pretreated for the second group, whereas SDF and KI were used for the third. After that, the pretreated dentin was immediately built with resin composite bonded with a universal adhesive and kept wet for 24 hours. Then, the pretreated molars were prepared into beam specimens for microtensile bond strength (µTBS), 16 for each group, and subjected to thermal aging. Lastly, they were tested using a universal testing machine, and the resulting data were analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post hoc test. It was found that the SDF-KI group had a significant difference with both the control and SDF groups (p < 0.05), while the control and SDF groups showed no significant differences (p = 0.310). The SDF-KI group had the highest mean value of 11.73 ± 4.39 megapascal (MPa). In contrast, the control group had the lowest mean value of 9.31 ± 3.41 MPa. Post hoc pairwise comparison results showed that SDF-KI pretreatment had a significantly higher strength value than the control and SDF groups. Pretreatment of demineralized primary dentin with SDF-KI does not negatively affect the immediate loading of resin composite. However, under the limitation of this study, KI application after SDF pretreatment is recommended to enhance the bond's durability of resin composite to demineralized dentin.

Abstract
Silver compounds have been used in medicine and dentistry for centuries. Their use in pediatric dentistry has long been restricted because of some drawbacks, chief among them being the discoloration of teeth with black stains. However, recent advances in technology have resulted in the development of new silver agents that do not have the limitations of previously used ones. This led to the reintroduction of silver compounds in pediatric dentistry. The aim of the present review was to examine the evidence supporting the therapeutic use of silver compounds in pediatric dentistry for caries arrest, as well as the mode of action and biocompatibility, characteristics, advantages, and disadvantages of different silver-containing agents.

Abstract
Caries/carious lesions are a growing concern among the general population across the world, and different strategies are evolving to combat the bacterial invasion that resultantly leads to caries. In this systematic review, we are looking to analyse the role of silver diamine fluoride (SDF) on the growth of bacterial biofilms. The search strategy for the studies to be selected for the review was initiated by a search across multiple databases, which ultimately yielded 15 studies that were in accordance with our objectives. The reviewed articles indicate a very clear correlation between the usage of SDF and the decrease in bacterial biofilms, which are limited not just to one or two but multiple bacterial species. As shown by the events favoring SDF's odds ratio of 3.59 (with a 95% confidence interval of 2.13 to 6.05), a risk ratio of 1.63 (1.32 to 2.00), and a risk difference of 0.28 (0.16 to 0.40), there was strong evidence that SDF is a successful treatment for reducing bacterial biofilms in dental practice. This study offers substantial proof that SDF works well to reduce bacterial biofilms in dentistry practices. We advise further investigation to examine the potential of SDF as a standard therapy choice for dental caries and related conditions given the obvious relationship between the use of SDF and the reduction in bacterial biofilms.

Abstract
OBJECTIVE To the effectiveness of different strategies to overcome silver diamine fluoride (SDF)-mediated tooth staining. MATERIALS AND METHODS Four online databases (PubMed, ScienceDirect, Scopus, and Web of Science) were searched using different MeSH terms and Boolean Operators to retrieve the articles (until June 2021), followed by a hand-search of the reference list of the included articles. All full-text, original studies in English that evaluated SDF staining and at least one SDF modification/alternative were included. RESULTS Among the assessed studies, nine studies explored the stain-minimization effect of potassium iodide (KI) post-application following SDF treatment. Among these, eight concluded that KI application after SDF treatment significantly reduced tooth staining, while one showed marginal staining following glass ionomer restoration of the SDF-treated dentine. Additionally, one study applied potassium fluoride (KF) and silver nitrate (AgNO3 ) concurrently to mitigate SDF-mediated staining. One study compared SDF staining with polyethylene glycol (PEG)-coated nanoparticles containing sodium fluoride (NaF), and another used nanosilver fluoride (NSF) for staining comparison with SDF. CONCLUSIONS Within the limitations of this study, the addition of different materials to SDF has proven to be a beneficial strategy for overcoming tooth staining associated with SDF. Future studies are warranted, particularly clinical trials, to validate these findings. CLINICAL SIGNIFICANCE SDF-mediated tooth staining is a serious concern that limits its clinical use. A review of various strategies to overcome this problem will help clinicians enhance its clinical use and patient acceptance.

Abstract
Aim This study aimed to evaluate the potential discolouration and carious lesion arresting effect of silver diamine fluoride (SDF) and silver diamine fluoride/potassium iodide (SDF/KI) in the treatment of carious primary teeth.Materials and method A total of 30 carious primary canines were randomly assigned to treatment groups where Group I was treated with SDF while Group II was treated with SDF/KI. Caries arrest was assessed based on consistency and stability of lesion size while the discolouration of treated lesions was assessed digitally using a VITA Easyshade spectrophotometer.Results Both treatments demonstrated 100% efficacy in arresting active caries lesions. Regarding discolouration, the total colour difference represented by delta E (ΔE) was 16.45 ± 5.69 for Group I compared to 9.54 ± 3.09 for Group II immediately post-operative, with a statistically significant difference (p = 0.003). Both groups showed similar values at 1, 3, 6 and 12 months after the treatment, with no statistically significant difference. No incidence of serious adverse effects related to either treatment and the majority of parents/guardians were satisfied with both treatments compromising their child's aesthetic appearance.Conclusions Both SDF and SDF/KI are effective in arresting carious lesions in primary teeth but in terms of the discolouration potential, the use of KI significantly reduced the discolouration caused by SDF immediately post-operatively. Unfortunately, marked discolouration was recorded in the subsequent follow-up visits, compromising the aesthetic outcome.

Abstract
Root caries is a growing problem for the worldwide aging population. Silver diamine fluoride (SDF) contains high concentrations of silver and fluoride ions, which prevents and arrests root caries, as well as dentin caries in the primary teeth of young children. Unlike other fluoride products that mainly reduce the formation of new carious lesions, 38% SDF is an effective agent that can efficiently arrest the carious process, remineralize the decayed dental tissues, and protect the tooth structure against the formation of new caries lesions. The use of SDF can result in more caries-resistant tooth structures. Despite these merits, its clinical disadvantages are the deep penetration of silver ions and sequential formation of silver compounds, which cause esthetic concern due to the discoloration and impaired efficacy of dentin bonding after using SDF. Thus, this narrative review, by addressing the primary experimental results and clinical applications of SDF on root caries, proposes management methods for root caries in conjunction with the application of SDF. We propose a two-visit treatment protocol to take advantage of the SDF application for root surface caries and utilize the discoloration caused by SDF.

Abstract
OBJECTIVE This study investigated the dentin remineralization effect of the application of a functionalized tri-calcium phosphate (fTCP) dentifrice and a silver diamine fluoride (SDF) solution. MATERIAL AND METHODS The materials used were: a fluoride-containing dentifrice with fTCP (fTCP+), a fluoride-containing dentifrice without fTCP (fTCP-) and a 38% SDF solution. Following treatment, the dentin slabs were immersed in a 0.1-M lactic acid buffer solution and then placed in artificial saliva. This procedure was repeated three times daily for 28 days. The propagation time of longitudinal ultrasonic velocities (UV) and the Knoop hardness (KH) of the samples were measured. The samples were also observed using scanning electron microscopy. RESULTS The SDF and fTCP+ groups showed higher UV than the fTCP - group regardless of the application method. The F-SDF group at 28 days showed significantly higher UV (4121 ± 102 m/s) than the F-fTCP + group (3731 ± 65 m/s) (p < .05). The F-SDF group at 28 days showed significantly higher KH (47.4 ± 2.2) than the F-fTCP+ group (43.3 ± 1.0) and the F-fTCP - group (42.9 ± 2.1) (p < .05). Closure of the dentinal tubules and crystal precipitation was detected on the surface of the fTCP+ group to a greater extent than the fTCP - group. CONCLUSIONS The fTCP-containing dentifrice and SDF solution effectively enhanced bovine dentin remineralization.

Abstract
Context Early childhood caries (ECC) is one of the most common diseases in the children of developing countries, affecting their oral health-related quality of life. From an economic perspective, silver diamine fluoride (SDF) can limit the progression of active carious lesions. Aims To estimate and compare the loss of shear bond strength among two adhesive materials on SDF-treated demineralized primary teeth dentin. Settings and Design Laboratory setting and in-vitro study design. Methods and Material For the in-vitro study, 40 primary teeth indicated for extraction were selected. The demineralization solution was 5% nitric acid. The samples were divided into four groups, Group 1 - GIC Type IX, Group 2 - Self-etch (SE) adhesive + G-Aenial Universal Flo, Group 3 - SDF + GIC Type IX, and Group 4 - SDF + SE adhesive + G-Aenial Universal Flo. Statistical Analysis Used Descriptive analysis and analysis of variance with Tukey's Post hoc test. Results The shear bond strength of GC G-Aenial Universal Flo(18.8165 ± 13.0448 MPa) found to be superior to GIC (5.7845 ± 1.8968 MPa). However, bond strength was significantly reduced with GC G-Aenial Universal Flo(34.0441 ± 14.1949/18.8165 ± 13.0448 MPa) compared to GIC (7.7956 ± 2.2804/5.7845 ± 1.8968 MPa) following the application of SDF. Conclusions It was concluded that SE adhesive + GC G-Aenial Universal Flois the material with better shear bond strength compared to GIC Type IX with and without SDF. Considering the severity and prevalence of ECC, socioeconomic strata of Indian population, the choice of material for masking the discoloration, and prevention of disease, GIC can be suggested as an alternative over GC G-Aenial Universal Flo.

Abstract
Introduction Due to its ability to arrest untreated dental caries, silver diamine fluoride (SDF) has been advocated for indirect pulp capping procedures. However, the high concentrations of silver and fluoride in SDF raise concerns about its biocompatibility to pulpal tissues. Objectives This study aimed to investigate the effect of SDF on the viability, alkaline phosphatase (ALP) activity, and morphology of pulpal-like cells (RPC-C2A) and to evaluate the influence of reduced glutathione (GSH) on SDF-induced cytotoxicity and deposit formation on dentin. Methodology The cytotoxicity of diluted 38% SDF solutions (10-4 and 10-5), with or without the addition of 5 mM or 50 mM GSH, was evaluated at 6 and 24 hours. Cell viability was detected using WST-8 and the effect on ALP activity was performed using an ALP assay kit. Cell morphology was observed using a phase-contrast microscope. Scanning electron microscopy analysis was conducted to evaluate the effect of GSH incorporation or conditioning on SDF-induced deposit formation on dentin discs. Cytotoxicity data were analyzed by two-way analysis of variance (ANOVA) and Tukey post hoc tests (p<0.05). Results There were significant differences between the groups. The results demonstrated that all tested SDF dilutions caused a remarkable cytotoxic effect, while the addition of GSH prevented SDF-induced damage at 6-hour exposure time in the higher dilution of SDF. Dentin treated with plain SDF or GSH-incorporated SDF solution showed deposit formation with occluded dentinal tubules, unlike the other groups. Conclusion SDF severely disturbed the viability, mineralization-ability, and morphology of pulpal-like cells, while controlled concentrations of GSH had a short-term protective effect against SDF-induced damage. GSH showed an inhibitory effect on SDF-induced dentinal deposit formation. Further research is warranted to evaluate the effect of GSH on caries-arresting, anti-hypersensitivity, and antibacterial functions of SDF.

Abstract
This study evaluated the ability of different types of silver diammine fluoride (SDF) to inhibit dentin demineralization using micro-focused X-ray computed-tomography (µCT). Dentin specimens were divided into five groups (n=10); no-treatment (control), 3.8% SDF (RC), 38% SDF, 38% SDF with potassium iodide (SDF/KI), and potassium fluoride (KF). The treated-dentin surfaces were subjected to demineralization for 7-days and assessed using µCT to determine mineral loss (ML) values. Specimens were also analyzed with scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The ML values of the SDF and KF groups were significantly lower than those of the RC and SDF/KI groups. EDS detected fluoride ions in the SDF and KF groups but not in the RC and SDF/KI groups. It was concluded that 38% SDF demonstrated a high ability to inhibit dentin demineralization while additional application of KI may diminish the inhibitory effect of SDF. The amount of dentin demineralization with SDF treatments was material dependent.

Abstract
This study aimed to examine whether discoloration of carious dentin after silver-diammine-fluoride (SDF) application might be used as a mean to detect demineralized-dentin. Fourty specimens were obtained from 20 human permanent teeth. Teeth were sectioned through the center of carious lesions to create 2-halves in which each half was assigned to a treatment group. Specimens were divided into two groups (n=20) (each half was assigned to one group) according to solution, namely Caries Check (CC), or SDF. SDF group was subdivided into 2 groups: light-cured and 2-day storage groups. The specimens were tested using light-microscope, microhardness test and SEM/EDS analysis. Repeated-measures ANOVA was used for statistical analysis. The light-microscope showed superficial discoloration in the CC-group while SDF (2-day storage) group showed deeper discoloration for the lesion area. SDF showed significant increase in the hardness compared with the CC-group. SDF showed potentiality to be used as an assisting-tool for caries detection.

Abstract
OBJECTIVE To investigate the effects of a 9.3-μm carbon dioxide (CO2) laser and silver diamine fluoride (SDF) on the prevention of enamel demineralisation and inhibition of cariogenic bacteria. METHODS Enamel blocks were applied with Laser (Group-1), SDF (Group-2), Laser + SDF (Group-3) and no treatment (Group-4), and then subjected to an 8-day pH-cycling for cariogenic challenge. Lesion depth and cross-sectional micro-hardness were assessed. Surface morphological and chemical changes were studied using scanning electron microscope (SEM) with energy dispersive spectroscopy (EDS). For the antibacterial activity, treated enamel blocks were incubated with Streptococcus mutans. The biofilm morphology, kinetics and viability were assessed by SEM, colony-forming units (CFUs) and confocal laser scanning microscope (CLSM), respectively. RESULTS Lesion depths (μm) for Group-1 to Group-4 were 88 ± 21, 26 ± 11, 13 ± 9 and 115 ± 25, respectively (p < 0.001; Group-2 and Group-3 < Group-1 < Group-4). Group-3 had a significantly higher cross-sectional micro-hardness than the other three groups. EDS determined that Group-4 had the lowest calcium-to-phosphorus molar ratio among the groups (p < 0.001). SEM images showed apparent bacteria accumulation on enamel surfaces in Group-4, but not in other groups. Log CFUs for Group-1 to Group-4 were 6.2 ± 0.6, 2.9 ± 0.8, 2.2 ± 1.1 and 7.3 ± 0.3, respectively (p < 0.001; Group-2 and Group-3 < Group-1 < Group-4). CLSM images revealed that live bacteria dominated in Group-4, but not in other groups. SIGNIFICANCE The irradiation with a 9.3-μm CO2 laser alone can prevent the demineralisation of enamel and reduce the adhesion of cariogenic bacteria. Moreover, adding SDF can significantly increase the preventive effect and antibacterial ability.

Abstract
Aim To evaluate and compare the effect of potassium iodide (KI) and glutathione (GSH) on tooth discoloration after application of 38% silver diamine fluoride (SDF) in primary molars.Method: Total of 30 primary molars were randomly divided into three groups of 10 each. Teeth were prepared and divided into: Group A—SDF only, Group B—SDF followed immediately by application of KI, and Group C—SDF was mixed with 25 mg of GSH. Final restoration was done using glass ionomer cement. Visual examination and color assessments using spectrophotometer were recorded at three time interval points, that is, day 1, 1 week, and 4 weeks. Results Statistical analysis was done using a repeated measures analysis of variances (ANOVA) test. The spectrophotometer results showed that Group A (SDF) exhibited the greatest amount of discoloration at all time intervals, while Group C (SDF + GSH) group was effective in decreasing the discoloration. Whereas, Group B (SDF + KI) significantly reduced the discoloration over the period of time. (p = 0.008). Conclusion KI can effectively reduce discoloration after application of 38% SDF. GSH can also be used as an alternative. Clinical Significance This two-step treatment for arresting caries can be a practical and low-cost option in areas with limited access to comprehensive dental care.

Abstract
This study evaluated the post-bleaching bonding performance of a one-step and two-step self-etch adhesive (SEA) to bleached enamel using in-office or at-home bleaching. Bovine enamel surfaces were treated with an in-office or at-home bleaching agent and divided into four post-bleach time periods: immediate, one day (1d), one week (1w) and one month (1m) before application of SEA systems. Enamel was bonded using the following procedures: Group 1: one-step SEA application (BeautiBond Multi, BBM), Group 2: two-step SEA application (FL-Bond II, FLBII). Microshear bond strengths (µSBS) were measured 24-h after bonding for each of the post-bleaching time periods. Acid-base resistant zones (ABRZs) were observed under SEM. Data were analyzed using three-way ANOVA. Bleaching caused a significant decrease of the immediate µSBSs for both adhesives (p≤0.005) then increased. Thick ABRZs were observed in BBM and FLBII after bleaching. Enamel µSBSs were adversely affected by bleaching. Thick ABRZ was created with bleaching.

Abstract
This study evaluated the effect of mechanical abrasion on the surface integrity, color change (ΔE) and antibacterial properties of demineralized and sound dentin surfaces treated with silver-diammine-fluoride (SDF). The dentin specimens were divided into two groups: sound and demineralized dentin, then divided into three sub-groups, control (no-treatment), SDF, and SDF + potassium-iodide (KI). Each sub-group was further divided into two groups, one exposed to mechanical brushing and the other without brushing. Specimens were analyzed for the ΔE, surface roughness/surface loss and antibacterial properties (CFU, optical density and fluorescent microscope). Repeated Measures ANOVA was used for statistical analysis of color change while one-way ANOVA was used for CFU analysis. SDF and SDI + KI groups showed significant reduction in ΔE with brushing in the sound dentin group unlike the demineralized group. The surface roughness values were higher for both SDF and SDF + KI groups but roughness values significantly decreased after brushing. Both SDF and SDF + KI groups revealed significantly less surface loss than control. The SDF group showed high anti-bacterial effect after brushing, unlike SDF + KI group. So, we concluded that mechanical brushing improved the esthetic outcome. While, SDF and SDF + KI could protect the dentin surface integrity. SDF-treated dentin possesses an antibacterial property even after mechanical brushing.

Abstract
BACKGROUND Silver diammine fluoride (SDF) applied before a restoration may prevent recurrent caries; therefore, its effect on the bonding of restorative materials is contradictory. AIM To assess through a systematic review and meta-analysis the influence of SDF on the bonding performance of adhesive materials to dentine. DESIGN A systematic search was carried out in PubMed, Web of Science, LILACS, and Scopus. Studies comparing bond strength of adhesive systems or glass ionomer cement to SDF-treated and -untreated (control) dentine were included. Global analysis comparing the bond strength data was performed, separately for adhesive systems and glass ionomer cement, using RevMan5.1, with a random-effect model, at a 5% significance level. RESULTS Eleven studies were included in the review and ten in the meta-analyses. Overall pooled effect for glass ionomer cement has shown no significant difference between the groups (Z = 0.47; P = .64). SDF treatment significantly impairs the bonding of adhesive systems to dentine (Z = 2.11; P = .03); this effect can be eliminated by the rinsing step (Z = 0.85; P = .40). CONCLUSIONS The previous application of SDF does not influence the dentine bond strength of glass ionomer cement, but compromises the bonding of adhesive systems.

Abstract
OBJECTIVE The aim of this study was to evaluate the penetration depth of silver into sound and demineralized dentin after application of silver diamine fluoride (SDF). METHODS Two hundred and eighty-eight dentin specimens were used. The specimens were divided into 3 groups: (1) sound dentin (control), (2) 30min EDTA-treated dentin; and (3) 13h EDTA-treated dentin. SDF was applied to all specimens. Each group was divided into 3 subgroups according to storage time into: 24h, 2 weeks and 1-year storage time. Each subgroup was further divided into four subgroups (n=8) according to different examinations as optical microscope (OM) observation, scanning electron microscopic (SEM) observation, elemental analysis with energy dispersive spectroscopy (EDS) and Micro-PIXE test. RESULTS The OM showed discoloration in the superficial layer after 24h and keep extending deeper after 2 weeks and 1-year. SEM showed silver crystals within dentinal tubules after 2 weeks and 1-year. EDS analysis can detect silver penetration only in the 1-year group reaching around 1200μm inside dentin. Micro-PIXE test detected silver at all time intervals, confirming the EDS depth results. SIGNIFICANCE It can be concluded that silver ions can completely infiltrate the demineralized dentin lesion with further penetration into the underlying mineralized dentin.
