Abstract: The effect of silver diamine fluoride (SDF) on the mineral content of carious dentine and the preventive caries effect of erbium-doped yttrium aluminium garnet (Er: YAG) laser irradiation (2,940 nm) combined with SDF application under cariogenic biofilm challenge model was investigated. Firstly, the SDF mechanism of action in the remineralisation of demineralised dentine process observing changes in the mineral content in vitro was investigated. Secondly, we investigated the effect of various laser irradiations at sub-ablative energy levels on the fluoride uptake of 38% SDF treated dentine. Finally, we evaluated the effects of Er: YAG laser irradiation combined with SDF application on the fluoride uptake by dentine under a cariogenic biofilm challenge. Compared with a 10% sodium fluoride and potassium fluoride solution and a 42% silver nitrate solution with the same content of fluoride and silver respectively, 38% SDF is more effective in promoting remineralisation of demineralised dentine. The dentine samples treated with SDF did not show evident demineralised surface morphology. Although the lesion depth for SDF treated samples was not significantly deeper than for sodium fluoride treated samples, it was demonstrated that SDF has an inhibitory effect on dentine demineralization. The results of the SDF-laser experiment showed that carbon dioxide (CO2) laser irradiation (10,600 nm) followed by Er: YAG laser irradiation at specific sublablative levels promoted the higher fluoride uptake from SDF application than neodymium-doped yttrium aluminium garnet(Nd: YAG) laser (1,064 nm) and diode laser (810 nm) irradiation. This study provides guidelines for the selection of the appropriate laser irradiation parameters and types to promote an optimal level of fluoride uptake for dentine caries prevention. Er: YAG laser irradiation was elected among the laser types in the previous experiment for promoting higher levels of fluoride uptake and for its maximal absorption by water and high absorption by hydroxyapatite. The Er: YAG SDF-laser treated dentine was subjected cariogenic bacterial challenge to investigate the caries preventive effect of this treatment. The morphological surface of the treated samples presented many occluded dentinal tubules. There was a major increase in the hardness and elastic moduli values and the fluoride content also increased significantly after the remineralisation process. To conclude, this study demonstrated that SDF application inhibited dentine demineralization and arrested caries, and that SDF application followed by Er: YAG laser irradiation promoted an increase in fluoride uptake by sound dentine under a cariogenic biofilm challenge.

This book was released on 2021 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental caries continues to be one of the most prevalent preventable diseases worldwide. Silver diamine fluoride (SDF) is a topical solution comprised of silver, ammonia and fluoride. It is a safe, effective, efficient, noninvasive and cost-effective method in caries management. However, there is little clinical evidence supporting the use of SDF (or SDF followed by application of potassium iodide[KI] to mitigate staining) as anti-caries agents on sound enamel and early enamel carious lesions. In this dissertation, I studied the mechanism behind SDF's ability to prevent coronal caries which has not been studied yet. In the first and second aims, I investigated the effectiveness of SDF, SDF+KI, fluoride (potassium fluoride [KF]) and silver (silver nitrate [AgNO3]) controls to SDF and deionized water (DIW) in preventing enamel demineralization and enhancing remineralization using chemical, biofilm and pH-cycling models. In both chemical demineralization and pH-cycling models there were no statistically significant differences between SDF and SDF+KI in preventing coronal caries. In the biofilm model, however, SDF+KI was significantly less effective in preventing demineralization than SDF. In the third aim, I investigated the efficacy of SDF, SDF+KI, KF, AgNO3, and DIW on the remineralization of active subclinical enamel carious lesions. Here, SDF+KI was significantly more effective in promoting remineralization than SDF. I calculated changes in color, and the results show applying KI after SDF significantly reduced the dark staining caused by SDF. In conclusion: SDF and SDF+KI appear to be effective options in preventing and in the treatment of primary coronal caries. Further clinical research is required to confirm the present findings.

Abstract: Abstract of thesis entitled Effectiveness of silver diamine fluoride and sodium fluoride varnish in arresting dentine caries submitted by Chu Chun Hung for the degree of Doctor of Philosophy at the University of Hong Kong in May 2004 Introduction: Caries prevalence in young children in China is high and most of the decayed teeth are left untreated. Conventional dental treatments are either not available or are unaffordable in many rural areas. Innovative approaches are needed to improve this situation. Aim: This prospective clinical trial investigated the effectiveness of topical fluoride applications in arresting dentine caries. The first null hypothesis to be tested was that there were no differences in the effectiveness of applying a 38% silver diamine fluoride (SDF) solution (44,800 ppm F), a 5% sodium fluoride (NaF) varnish (22,600 ppm F) and water in arresting dentine caries. The second null hypothesis was that caries removal prior to fluoride application had no impact on its effectiveness in arresting dentine caries. Methods: A total of 375 Chinese kindergarten children, aged 3-5 years with carious upper anterior teeth were divided into five groups. Children in the first and second groups received annual applications of SDF. NaF was applied every three months onto the lesions of children in the third and fourth groups. For children in the first and third groups, soft carious tissues were removed with hand instruments prior to fluoride application at the baseline examination. The fifth group of children received annual applications of water. Follow-up examinations were performed every six months. The children's parents completed a questionnaire to assess parental satisfaction with the appearance of the upper anterior teeth of their child before treatment and again at 24 months after treatment. Results: A total of 308 children were followed for 30 months. The respective mean numbers of arrested caries tooth surfaces in the five groups of children were 2.5, 2.8, 1.5, 1.5 and 1.3 (pDOI: 10.5353/th_b3016250 Subjects: Dental caries - Prevention Dental caries in children Fluorides - Therapeutic use Sodium fluoride - Therapeutic use

Book excerpt: Dental caries specifically ECC, remains a remarkable issue in certain parts of society, particularly those with low socioeconomic status and with scarce health care services. Techniques that promote less discomfort, such as the application of silver diamine fluoride, should be preferred and considered. Treatment of the disease is needed as children with an active caries lesion in their primary dentition can also present with caries lesions in their permanent dentition. By arresting and preventing the progression of caries, SDF offers an intervening care path for young children for whom traditional restorative treatment is not instantly available nor unacceptable by the children. This book on SDF highlights the properties of SDF and clinical recommendations on its use, safety for clinicians, the pros and cons of SDF solution in the clinical use of young children.

Download or read book Silver Fluoride and Caries Management written by Raman Bedi and published by Frontiers Media SA. This book was released on 2024-09-13 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World Health Organization (WHO) have classified the dental caries epidemic as a global public health priority. A global action plan has been published, and by 2030, each country needs to reduce the dental caries burden and implement a universal health care strategy. Public and private oral health care expenditure has reached an estimated 387 billion US dollars, and its distribution is unequal, with most costs occurring in high-income settings. Dental caries is estimated to impact 3.5 billion people and is more significant than any other Non-communicable disease. The majority of dental cavities are untreated. In 2021, the WHO Essential Medicine Committee included, for the first time, silver diamine fluoride (SDF) as a critical medicine. SDF was listed as a caries arresting product. Silver fluoride product has recently been introduced to the dental market and initial evidence is that it is also as effective in arresting caries.

This book was released on 2017-10-19 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Case reports and clinical trials conducted in various countries show, more and more frequently, a positive correlation between the presence of original teeth and prevalence of root caries in older age. Because this is a global trend, it is likely that the predicted increase in the worldwide elderly population may soon cause a significant increase in the number of people requiring effective means of preventing and treating root surface caries. In response to this development, a team of outstanding contributors has reviewed the most important aspects of root caries. This new volume presents their findings along with discussions of how to deal with this health issue that progressively affects the oral health balance. The chapters in this book are divided in four core parts: Epidemiology, Biological Determinants, Lesion Assessment and Features and Preventive and Operative Therapies. The collection of state-of-the-art articles provides a broad overview and will serve as a reference for clinicians as well as scientists and, hopefully, will encourage new research.

Abstract: Introduction: Silver diammine fluoride (SDF) has been found to be effective in preventing and in arresting dental caries in primary teeth. Clinical evidence to support its use for managing dental root caries in elders is limited. Besides, no clinical study has been conducted to reduce the staining caused by SDF on the arrested caries lesions. Objectives: This study aimed to investigate the effectiveness of SDF in preventing and in arresting dental root caries in elders and to assess the effects of applying potassium iodide (KI) after SDF application on the color of arrested root caries lesions. Methods: This study was conducted among community-dwelling elders in Hong Kong. Elders who had at least 5 teeth with exposed root surfaces were randomly allocated into three intervention groups as follows: Group 1 - received oral hygiene instruction (OHI) and soda water (placebo control); Group 2 - received OHI and annual application of SDF solution; and Group 3 - received OHI and annual application of SDF solution followed immediately by KI solution. Status of the dental root surfaces was assessed clinically every 6 months by the same independent examiner. Color of the arrested root caries lesion was assessed using PANTONE color sheets. Results: A total of 323 elders (mean age=72.1) with 13499 sound exposed root surfaces were examined at baseline. Among them, 257 (79.6%) were followed for 30 months. The mean numbers of dental root surface with new caries found at the 30-month examination in Groups 1, 2, and 3 were 1.1, 0.4, and 0.6 respectively (ANOVA, pAmong the 323 elders, 83 elders with 157 root surfaces with active caries lesion were found at baseline. After 30 months, 67 (80.7%) elders with 100 (63.7%) root caries lesions were reviewed. The arrest rates of root caries at the 30-month examination were 45%, 90%, and 93% in Groups 1, 2, and 3, respectively (χ DEGREES2 test, PIn addition, the distributions of arrested carious lesions by color were not significantly different between the SDF and SDF/KI groups (Fisher's exact test, P>0.05). Conclusions: Annual topical application of either SDF solution or SDF/KI solution is effective in preventing and in arresting dental root caries among community-dwelling elders. The application of KI solution does not affect the effectiveness of SDF solution and also does not reduce the black staining caused by SDF solution.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To investigate the efficacy of silver diamine fluoride (SDF) with 5% fluoride varnish (FV) in treating cavitated caries in young children and to explore the association between SDF treatment and oral health-related quality of life (OHRQoL). Methods: Children with active dentinal caries lesions (ICDAS 5 or 6) in primary teeth underwent treatment with 38% SDF and 5% FV at baseline and 4 months later. Treated lesions were assessed 4 and 8 months after baseline to determine arrest. Participants were deemed Completely Successful (CS) if all treated lesions were arrested and Incompletely Successful (IS) if at least one lesion was not arrested. The early childhood oral health impact scale (ECOHIS) questionnaire was completed at second and third visits. Statistical analyses included descriptive and bivariate methods. A P value ≤ 0.05 was significant. Results: Forty children with 239 caries lesions were enrolled; mean age 40.2 +/- 14.9 months and 45% male. Lesion arrest rates after one and two applications of SDF were 74.1% and 96.2%, respectively. Children who reportedly brushed twice daily were more likely to be in the CS group compared to those who brushed less (p=0.006). Participants in the CS group had a significantly lower mean baseline dmft score than those in the IS group (p= 0.048). No significant difference in OHRQoL was observed between CS and IS groups. Conclusions: SDF with 5% FV is an effective approach to the management of ECC; more than one application is recommended along with regular follow-up of patients and twice daily brushing. OHRQoL was not found to be affected by the level of success of SDF treatment.

Epidemiological studies reported that most of the ECC are left untreated. While young children may not be co-operative enough for conventional restorative treatments, silver diamine fluoride (SDF) can be topically applied on tooth surfaces as a cariostatic agent. Previous clinical trials have confirmed that annual application of 38% SDF is effective in arresting dentin caries in preschool children. However, information about the effectiveness of SDF with different combinations of concentration and frequency is still lacking. This information is important for the optimal application of SDF in the future public health programs for caries control. This prospective randomized controlled trial aimed to investigate and compare the effectiveness of 12% and 38% SDF when applied annually or biannually in arresting dentin caries of primary teeth of preschool children for 30 months. The two null hypotheses tested were firstly, there is no difference in effectiveness when SDF is applied at 12% or 38% in arresting dentin caries of preschool children; and secondly, there is no difference in effectiveness when SDF is applied annually or biannually in arresting dentin caries of preschool children. A total of 888 healthy and cooperative K1 children aged 3-4 years with at least one dentin caries surface were recruited and randomized into four treatment groups: Group 1 received annual applications of 12% SDF, Group 2 received biannual applications of 12% SDF, Group 3 received annual applications of 38% SDF, and Group 4 received biannual applications of 38% SDF. Group 3 was assigned as the positive control group. Primary outcome was soft dentin caries surface at baseline that became arrested at the follow-up examinations. Clinical examinations were conducted at the kindergartens every 6 months by the same trained examiner. Parental questionnaires were used to collect the children's demographic information, oral hygiene related habits, parental satisfaction with children's dental appearance and dental health at baseline, 18- and 30-month examinations. Adverse effects after treatments including increment of non-vital teeth, complaint about tooth or gingival discomfort, gingival discoloration, and black staining over arrested surfaces were also recorded. A total of 798 children with 3,268 caries surfaces were examined at 30-month follow-up. The dropout rates of the four groups were similar. The respective proportions of arrested surfaces in Group 1 to Group 4 were 48.7%, 54.0%, 60.6%, and 66.9%, respectively (p To conclude, SDF is more effective in arresting dentin caries in primary teeth of preschool children at 38% than 12%, and when applied biannually than annually. Clinical significant improvement in effectiveness can be achieved by increasing its concentration. DOI: 10.5353/th_b5435643 Subjects: Denta
