[PMID: 39025427 DOI: 10.1016/j.jdent.2024.105247] [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: 05/29/2024] [Revised: 07/14/2024] [Accepted: 07/16/2024] [Indexed: 07/20/2024] Open
Abstract
OBJECTIVE To assess the fluoride and silver ion release of glass ionomer cement (GIC) restorations, including conventional GIC (CGIC) and resin-modified GIC (RMGIC) restorations, with 38 % silver diamine fluoride (SDF) solution dentin pretreatment. METHODS Eighty dentin blocks were allocated into 4 groups and restored with SDF+CGIC, CGIC, SDF+RMGIC and RMGIC, respectively. Each block was stored in deionized water at 37 °C for 2 years. Fluoride and silver ion concentration in storage solution was measured using ion-selective electrode and inductively coupled plasma-optical emission spectrometry for up to 2 years. The cross-sectional surfaces of restored dentin blocks were assessed by X-Ray diffraction analysis (XRD), scanning electron microscope (SEM) with energy-dispersive X-ray spectroscopy (EDS) after 1 week and 2 years, respectively. RESULTS The mean ± standard deviation (SD) of accumulative fluoride releasing in SDF+CGIC, CGIC, SDF+RMGIC and RMGIC for 2 years were 0.13±0.005 mg, 0.09±0.006 mg, 0.15±0.008 mg and 0.05±0.003 mg, respectively (Groups SDF+RMGIC > SDF+CGIC > CGIC >RMGIC, p < 0.05). The mean ± SD of accumulative silver releasing in SDF+CGIC, CGIC, SDF+RMGIC and RMGIC for 2 years were 0.03±0.009 mg, 0.00±0.00 mg, 0.01±0.003 mg, and 0.00±0.00 mg, respectively (Groups SDF+CGIC > SDF+RMGIC > CGIC&RMGIC, p < 0.05). Groups SDF+CGIC and SDF+RMGIC showed sustainably higher fluoride and silver releasing compared to Groups CGIC and RMGIC (p < 0.05). XRD analysis indicated the fluorapatite and silver chloride were observed only in Groups SDF+CGIC and SDF+RMGIC, but not in Groups CGIC and RMGIC. SEM images of the cross-sectional view of the dentin blocks showed silver crystals within dentinal tubules 1 week and 2-year in Groups with SDF pretreatment. CONCLUSION The 38 % SDF dentin pretreatment sustainably increased the fluoride and silver release of GIC and RMGIC restorations for up to 2 years.

Sun IG, Duangthip D, Zheng FM, Luo BW, Lo ECM, Chu CH. A randomised clinical trial to arrest caries using silver diamine fluoride therapy with two postoperative instructions. J Dent 2024:105308. [PMID: 39137876 DOI: 10.1016/j.jdent.2024.105308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 08/07/2024] [Accepted: 08/10/2024] [Indexed: 08/15/2024] Open
Abstract
OBJECTIVE The objective of this study is to investigate the beneficial effect of not rinsing for 30 minutes in arresting early childhood caries after SDF therapy. METHODS This randomised clinical trial recruited 3- to 4-year-old kindergarten children with active (soft) dentine caries. A questionnaire was sent to the parents to collect children's demographic data and oral health-related behaviours. A dentist conducted an oral examination and measured the caries experience using dmft index and oral hygiene using visible plaque index. After 38% SDF therapy, the children were randomly allocated into two groups. Children in group A were instructed to rinse with water immediately, whereas children in group B were asked to refrain from rinsing, drinking, or eating for 30 minutes. After six months, the same examiner determined the lesion activity (active/arrest) of the SDF-treated carious tooth surface. Generalized Estimating Equations was used to compare the proportion of caries arrest (caries-arrest rate) between the two groups. RESULTS This study recruited 298 children with 1,158 decayed tooth surfaces receiving SDF therapy at baseline and evaluated 275 (92%) children with 1,069 (92%) SDF-treated tooth-surface at the six-month examination. The demographic background, oral hygiene and caries status of two groups were comparable at baseline (p>0.05). The caries-arrest rate for group A and group B were 65% (337/519) and 61% (338/550), respectively (p=0.28). CONCLUSION This randomised clinical trial found the postoperative instructions of immediate rinsing or refraining from rinsing, drinking, or eating for 30 minutes after SDF therapy had no significant effect on caries arrest in primary teeth. CONCLUSION This randomised clinical trial found not rinsing for 30 minutes after SDF therapy is not better than immediate rinsing in arresting early childhood caries. CLINICAL SIGNIFICANCE Topical SDF application leaves an unpleasant taste in the mouth, which may affect the acceptance or even rejection of SDF therapy among young children. This study provides clinicians with information to make their decision on postoperative instruction after SDF therapy.

[PMID: 38810833 DOI: 10.1016/j.jdent.2024.105097] [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: 04/04/2024] [Revised: 05/16/2024] [Accepted: 05/23/2024] [Indexed: 05/31/2024] Open
Abstract
OBJECTIVES This study aims to evaluate antibacterial effects of silver diamine fluoride (SDF), SDF/potassium iodide (KI), and nanosilver fluoride (NSF). METHODS Antimicrobial activity of sterile saline, 5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), SDF, SDF/KI, NSF, and KI solutions against Streptococcus mutans and Lactobacillus casei was assessed through disc diffusion tests. A dual-species biofilm of S. mutans-L. casei was formed on 48 enamel samples, divided into six groups (n = 8). Group 1 was treated with sterile saline, Group 2 with 5% NaOCl, Group 3 with 2% CHX, Group 4 with SDF, Group 5 with SDF/KI, and Group 6 with NSF. The samples were analysed using confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). Statistical analysis utilized Shapiro-Wilk and Kruskal-Wallis tests and multiple comparisons were conducted using Dunn test. RESULTS SDF, SDF/KI, and NaOCl displayed significantly higher antibacterial activity against dual-species biofilm compared to NSF and CHX (p < 0.050). CONCLUSIONS In conclusion, SDF and SDF/KI demonstrated greater antibacterial activity than NSF. SDF's antibacterial activity was unaffected by KI. Further research is needed to determine the appropriate content and concentration for achieving effective antibacterial activity with NSF. CLINICAL SIGNIFICANCE The use of silver-containing materials is increasing in popularity within pediatric dentistry. In this study, an endeavor has been made to assist pediatric dentists in determining which solution might be more advantageous for preventing caries.

Abstract
BACKGROUND The black staining effect of silver-containing solutions for use to arrest caries can have a negative aesthetic impact on children and parents. This study aims to assess the staining effects of Silver Diamine Fluoride/Potassium Iodide (SDF/KI), SDF and Nanosilver Fluoride (NSF). MATERIALS AND METHODS Forty-four extracted carious primary molars were collected and randomly divided into four groups (n = 11). The carious tissue in all teeth was removed using a chemo-mechanical caries removal agent with an excavator. After caries removal in all groups, SDF, SDF/KI, and NSF were applied to the different groups, while no solution was applied to the control group. Subsequently, the teeth in all groups were restored with compomer. Color values L*, a* and b* were measured using a spectrophotometer at three time points: immediately after compomer restoration (T0), one week later (T1), and four week later (T2). Changes in brightness (ΔL) and color (ΔE) over time were calculated and comparisons among groups were made. RESULTS The SDF solution induced statistically significant black staining (p = 0.013) and a decrease in L* value (p < 0.001) on the compomer material compared to the other groups over time. CONCLUSIONS It was observed that SDF/KI has the potential to reduce the black staining effect of SDF, though not entirely. Novel experimental solutions like NSF may offer an alternative to counteract the staining effect of SDF.

Abstract
Silver diamine fluoride (SDF) is a topical solution used for managing dental caries. The mixed-methods study consists of a quantitative study (questionnaire survey) and a qualitative study (in-depth interview) to explore the knowledge, attitudes, and practices towards SDF among dentists in Vietnam. A descriptive approach and a thematic approach were performed to analyze data, respectively. The questionnaire survey invited 436 licensed dentists registered for the national annual dental meeting and 226 dentists participated (response rate: 52%). Among them, 174 (77%, 174/226) dentists knew SDF, and 69 (40%, 69/174) dentists used SDF for caries management. Most of them considered SDF therapy as non-invasive (84%, 146/174) and simple (80%, 140/174). However, most of them expressed concern that SDF could discolor the tooth (74%, 128/174). Their most preferred teeth for SDF therapy were primary posterior teeth (92%, 160/174). The in-depth interview consulted 16 dentists to reach data saturation. They learned about SDF from outside curriculum resources as an effective anti-caries agent. They understood the advantages (simple, non-invasive, timesaving) and disadvantages (tooth discoloring, ammonia odor) of SDF. They used SDF to arrest caries in uncooperative children in the clinic and people living in rural areas in outreach services. Most dentists in Vietnam are supportive of SDF therapy, and they know its advantages and disadvantages for caries management. The results addressed the aim of the study to investigate Vietnamese dentists' perspectives towards SDF.

Abstract
OBJECTIVES Silver diamine fluoride (SDF) has gained popularity in dentistry as an anti-hypersensitive and anti-caries agent. This study aims to review the postoperative instructions for SDF therapy and examine the evidence supporting these instructions in treating dentine hypersensitivity and caries control. DATA AND SOURCES Two independent reviewers searched three electronic databases (EMBASE, PubMed, and Web of Science) to identify clinical studies that used SDF to treat dentine hypersensitivity and dental caries. Additionally, they searched Google Chrome for information from manufacturers, the department of health, national dental organisations, authoritative dental organisations, and universities regarding SDF therapy for these conditions. Data on postoperative instructions were extracted, and their impact on the treatment of dentine hypersensitivity and caries control was investigated. STUDY SELECTION This review included 74 clinical studies, 11 sets of instructions from SDF manufacturers, and six recommendations from national dental organisations, departments of health and universities. Amongst the included records, 50 clinical studies, two manufacturers, and one department of health mentioned postoperative instructions for SDF therapy. The recommendations varied, from suggesting no specific instructions, immediate rinsing, refraining from eating or drinking for 30 to 60 min, and even avoiding brushing until the next day after SDF therapy. Notably, no clinical studies reported the effects of these postoperative instructions on the SDF treatment of dentine hypersensitivity or dental caries. CONCLUSIONS This scoping review highlights the presence of inconsistent postoperative instructions for SDF therapy in the treatment of dentine hypersensitivity and caries control. Furthermore, there is a lack of evidence supporting the effectiveness of these instructions. CLINICAL SIGNIFICANCE No evidence supports the postoperative instructions for SDF therapy for managing dentine hypersensitivity and dental caries. Studies are necessary to provide guidance for clinicians using SDF in their clinical practice.

Abstract
OBJECTIVE To assess the clinical evidence for silver diamine fluoride (SDF) to reduce dentine hypersensitivity in adults. METHODS Two independent researchers searched the English literature in five databases (Scopus, PubMed, Web of Science, EMBASE and the Cochrane Library) up to 15th July 2023 for clinical trials investigating the desensitising effect of professionally applied SDF to manage dentine hypersensitivity in adults aged 18 or above at any follow-up period. The primary outcome was the change in dentine hypersensitivity between baseline and follow-up visits after SDF application regarding any validated pain outcome measures. The Cochrane guidelines were used for the risk of bias assessment. RESULTS Three hundred and thirty-one studies were identified, and four of them were finally included. Three of the included studies were rated as having a 'low risk' of bias. The SDF solution reduced dentine hypersensitivity in adults. The percentage reduction in dentine hypersensitivity ranged from 23 % to 56 % after a single application of SDF solution. Moreover, the SDF solution was more effective than potassium nitrate, potassium oxalate and glutaraldehyde plus hydroxyethyl methacrylate in reducing dentine hypersensitivity. Meta-analysis indicated a more significant reduction in visual analogue scales (1-10) by 1.35 (95 % CI:0.9-1.8; p<0.00001) after receiving the SDF application than controls. CONCLUSION The included clinical trials showed that SDF solution reduced dentine hypersensitivity in adults. However, clinical trials are few, and their protocol varied from one another. Further well-designed clinical trials should be conducted to provide more evidence on its use to manage dentine hypersensitivity. CLINICAL SIGNIFICANCE SDF is cleared as desensitizing agents by the US Food and Drug Administration to manage dentine hypersensitivity, which induces pain, limits food choice, and impacts the quality of life. Evidence from this systematic review informs clinicians and provides researchers insight for future research on SDF use for dentine hypersensitivity.

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
OBJECTIVE This study aims to determine the stability, alkalinity, and fluoride and silver ion concentrations of 5 commercially available 38% silver diamine fluoride (SDF) solutions-namely Advantage Arrest, e-SDF, Riva Star, Saforide, and Topamine-in 180 days. METHODS Alkalinity was determined using a pH electrode. The fluoride and silver ion concentrations were obtained using a calibrated ion-selective electrode and optical emission spectrometer, respectively. Six bottles of each product were examined on days 0 (freshly opened), 30, 60, 90, and 180. The time taken for each freshly opened product to form a black silver precipitate under room light (500 lx) and 25 °C was also recorded. RESULTS For 180 days, Advantage Arrest, e-SDF, Riva Star, Saforide, and Topamine had the pH range of 9.8-9.8, 10.5-10.6, 13.0-13.1, 9.8-9.8, and 9.3-9.4; fluoride ion concentration range (nearest 1000 ppm) of 40.9%-42.4%, 46.7%-50.9%, 37.0%-39.0%, 37.0%-45.7%, and 47.7%-53.4%; silver ion concentration range (nearest 1000 ppm) of 283.4-307.0, 307.3-315.4, 418.6-435.7, 266.3-281.0, and 416.2-456.1 ppm; and precipitation time (nearest hour) of 17, 12, 6, 7, and 7 hours, respectively. The percentage change of fluoride and silver could be more than 5% after 60 days. CONCLUSIONS The alkalinity of the 5 SDF solutions remained stable after 180 days. In addition, their fluoride and silver concentrations decreased substantially after 60 days. The freshly opened SDF solutions did not precipitate within 5 hours under ambient room conditions. The alkalinity and fluoride and silver concentrations of the 38% SDF solutions could be less stable after 60 days; thereafter, the fluoride and silver concentrations decreased. Thus, the SDF solution should be used within 60 days after opening.

Abstract
The Scientific Investigation Committee of the American Academy of Restorative Dentistry offers this review of the 2022 dental literature to briefly touch on several topics of interest to modern restorative dentistry. Each committee member brings discipline-specific expertise in their subject areas that include (in order of the appearance in this report): prosthodontics; periodontics, alveolar bone, and peri-implant tissues; dental materials and therapeutics; occlusion and temporomandibular disorders; sleep-related breathing disorders; oral medicine and oral and maxillofacial surgery; and dental caries and cariology. The authors focused their efforts on reporting information likely to influence the daily dental treatment decisions of the reader with an emphasis on innovations, new materials and processes, and future trends in dentistry. With the tremendous volume of literature published daily in dentistry and related disciplines, this review cannot be comprehensive. Instead, its purpose is to update interested readers and provide valuable resource material for those willing to subsequently pursue greater detail on their own. Our intent remains to assist colleagues in navigating the tremendous volume of newly minted information produced annually. Finally, we hope that readers find this work helpful in managing patients.

[PMID: 37454789 DOI: 10.1016/j.jdent.2023.104616] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/04/2023] [Accepted: 07/11/2023] [Indexed: 07/18/2023] Open
Abstract
OBJECTIVE This study aimed to evaluate the desensitizing effect of topically applied 38% silver diamine fluoride (SDF) solution on the exposed root surface of hypersensitive teeth in older adults. METHOD This double-blind randomised clinical trial recruited healthy older adults with dentine hypersensitivity. A trained examiner tested the most hypersensitive tooth root surface with a blast of compressed cold air from a three-in-one syringe. The participants gave a sensitivity score (SS) in visual analogue scale from 0 (no pain) to 10 (agonizing) at the baseline visit. Then, they received 38% SDF or 5% potassium nitrate solution (control) as intervention on the root surface. After the intervention, they received a compressed cold air test and reported the SS again. The compressed cold air test followed by intervention was repeated at 4- and 8-week follow ups. The primary outcome was the reduction in SS at 8-week follow-up with reference to the SS at baseline before intervention. Shapiro-Wilk and Mann-Whitney U tests were performed for data analysis following a normality test of SS. RESULTS This trial recruited 148 participants, and 139 (94%) participants completed the trial. The median percentage reductions in SS in the SDF and potassium nitrate groups were 60% and 50%, respectively (p < 0.001). CONCLUSION According to the results, 38% SDF solution reduced hypersensitivity on the exposed root surface of older adults. In addition, 38% SDF was more effective than 5% potassium nitrate solution to reduce hypersensitivity on the exposed root surface of older adults. CLINICAL SIGNIFICANCE Dentin hypersensitivity is common amongst older adults and negatively affects their quality of life. To date, there is no gold standard professionally applied desensitizing therapy in treating hypersensitivity. Evidence from this clinical trial could aid clinical practice and improve oral health in older adults. TRIAL REGISTRATION This study was registered at ClinicalTrials.gov (NCT05392868).

Evaluation of the remineralizing capacity of silver diamine fluoride on demineralized dentin under pH-cycling conditions. J Appl Oral Sci 2023; 31:e20220306. [PMID: 36995879 PMCID: PMC10065761 DOI: 10.1590/1678-7757-2022-0306] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 01/17/2023] [Indexed: 03/29/2023] Open
Abstract
OBJECTIVE (1) to determine the effects of the silver diamine fluoride (SDF) and sodium fluoride (NaF) in demineralized dentin exposed to an acid challenge by pH-cycling, (2) to evaluate the remineralizing capacity of SDF/NaF products based on the physicochemical and mechanical properties of the treated dentin surfaces. METHODOLOGY In total, 57 human molars were evaluated in different stages of the experimental period: sound dentin - negative control (Stage 1), demineralized dentin - positive control (Stage 2), and dentin treated with SDF/NaF products + pH-c (Stage 3). Several commercial products were used for the SDF treatment: Saforide, RivaStar, and Cariestop. The mineral composition and crystalline and morphological characteristics of the dentin samples from each experimental stage were evaluated by infrared spectroscopy (ATR-FTIR), X-ray diffraction, and electron microscopy (SEM-EDX) analytical techniques. Moreover, the mechanical response of the samples was analyzed by means of the three-point bending test. Statistics were estimated for ATR-FTIR variables by Wilcoxon test, while the mechanical data analyses were performed using Kruskal-Wallis and Mann Whitney U tests. RESULTS Regarding the chemical composition, we observed a higher mineral/organic content in the SDF/NaF treated dentin + pH-c groups (Stage 3) than in the positive control groups (Saforide p=0.03; Cariestop p=0.008; RivaStar p=0.013; NaF p=0.04). The XRD results showed that the crystallite size of hydroxyapatite increased in the SDF/NaF treated dentin + pH-c groups (between +63% in RivaStar to +108% in Saforide), regarding the positive control. SEM images showed that after application of the SDF/NaF products a crystalline precipitate formed on the dentin surface and partially filled the dentin tubules. The flexural strength (MPa) values were higher in the dentin treated with SDF/NaF + pH-c (Stage 3) compared to the positive control groups (Saforide p=0.002; Cariestop p=0.04; RivaStar p=0.04; NaF p=0.02). CONCLUSIONS The application of SDF/NaF affected the physicochemical and mechanical properties of demineralized dentin. According to the results, the use of SFD/NaF had a remineralizing effect on the dentin surface even under acid challenge.

Yan IG, Zheng FM, Gao SS, Duangthip D, Lo ECM, Chu CH. A Review of the Protocol of SDF Therapy for Arresting Caries. Int Dent J 2022; 72:579-588. [PMID: 35843730 PMCID: PMC9485517 DOI: 10.1016/j.identj.2022.06.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Accepted: 06/10/2022] [Indexed: 11/13/2022] Open
Abstract
Objective The aim of this work was to review the protocol of the use of silver diamine fluoride (SDF) for arresting caries, specifically the application time. Method Two researchers searched manufacturers’ instructions, YouTube videos, and 5 databases (Embase, Medline, PubMed, Scopus, and Web of Science). Manufacturers’ instructions, videos from national dental organisations, and peer-reviewed journal articles that published the SDF application protocol in English for arresting caries were selected. Results The review included 14 protocols from 15 publications from 4 manufacturers, 3 dental associations, and 7 author teams (one team had 2 articles). The American Dental Association and the British Society of Paediatric Dentistry provided their SDF application protocols on YouTube. The American Academy of Paediatric Dentistry and 7 author teams published their protocols in journal articles. Seven publications suggested an SDF application time of 60 seconds. Seven publications suggested a time range of 10 seconds to 240 seconds. Two publications suggested caries excavation, but 4 publications suggested no caries excavation before SDF application. The procedures from at least 5 publications involved protecting the gingiva with petroleum jelly, isolating the carious tooth with cotton rolls, drying the carious lesion with a 3-in-1 syringe, applying SDF solution with a micro brush for 60 seconds, removing excess SDF solution with gauze, and applying fluoride varnish to the SDF-treated lesion. Conclusions Although the SDF application protocol is simple and straightforward, the published protocols could be different. Most publications suggested an SDF application time of 60 seconds, which can be long, particularly for young children and older adults.
