Silver nitrate has been adopted for medical use as a disinfectant for eye disease and burned wounds. In dentistry, it is an active ingredient of Howe's solution used to prevent and arrest dental caries. While medical use of silver nitrate as a disinfectant became subsidiary with the discovery of antibiotics, its use in caries treatment also diminished with the use of fluoride in caries prevention. Since then, fluoride agents, particularly sodium fluoride, have gained popularity in caries prevention. However, caries is an infection caused by cariogenic bacteria, which demineralise enamel and dentine...

OBJECTIVE: To compare the effectiveness of three applications of silver diammine fluoride (SDF) solution at yearly interval and three applications of SDF solution or sodium fluoride (NaF) varnish at weekly interval at baseline in arresting active caries in the primary teeth of preschool children. METHODS: Children aged 3-4 years (n = 371) who had at least one active caries lesion (ICDAS codes 3-6) in their primary teeth were randomly allocated into three groups: Group 1 - annual application of 30% SDF solution; Group 2 - three applications of 30% SDF at weekly intervals; and Group 3 - three applications of 5% NaF varnish at weekly intervals...

This randomized clinical trial aimed to compare the adverse effects and parental satisfaction following the different regimes of silver diamine fluoride (SDF) treatment among preschool children. A total of 888 preschool children who had active dentin caries received different SDF application regimes: group 1, 12% SDF applied annually; group 2, 12% SDF applied semiannually; group 3, 38% SDF applied annually; and group 4, 38% SDF applied semiannually. Information on adverse effects-including tooth or gum pain, gum swelling, gum bleaching, and systemic toxicity-was collected through a parent-reported questionnaire within 1 wk after every SDF or placebo application...

Introduction: Dental caries is still prevailing worldwide, although different anti caries products have been introduced. Each remineralizing agent has its own shortcomings. Therefore, looking for new agents to have benefits of previous ones with lesser side effects is worthwhile. Aim: To determine the remineralization ability of NaF varnish, nano-Hydroxyapatite Serum (n-HAP) and Nano Silver Fluoride (NSF) on enamel of primary anterior teeth. Materials and Methods: Incipient caries were induced in primary sound anterior teeth by storing each specimen in demineralization solution for 72 hours...

Silver diamine fluoride is a topically-applied agent for managing dental caries. It stops caries lesion progression, turning them black and hard in a high percentage of cases. Populations including pediatric, geriatric, special health care needs, and those with limited access to oral health care can all benefit from silver diamine fluoride. This commentary addresses some of the many questions that have arisen with the availability of SDF and marked gaps in our knowledge.

BACKGROUND: This manuscript presents evidence-based guidance on the use of 38 percent silver diamine fluoride (SDF) for dental caries management in children and adolescents, including those with special health care needs. A guideline workgroup formed by the American Academy of Pediatric Dentistry developed guidance and an evidence-based recommendation regarding the application of 38 percent SDF to arrest cavitated caries lesions in primary teeth. TYPES OF STUDIES REVIEWED: The basis of the guideline's recommendation is evidence from an existing systematic review "Clinical trials of silver diamine fluoride in arresting caries among children: A systematic review...

The purpose of this study was to evaluate the antimicrobial properties of a new formulation containing silver nanoparticles, named Nano Silver Fluoride (NSF), to inhibit Streptococcus mutans biofilm formation on children's dental enamel. The variations in dental biofilm pH and in the Simplified-Oral-Hygiene-Index (OHI-S) also were evaluated after the treatment with NSF. This was a randomized, double-blind, crossover and prospective pilot clinical trial study in which 12 schoolchildren, aged between 7-8 years, had their dental enamel treated with two solutions: S1 - Nano Silver Fluoride and S2 - negative control (saline solution), in different experimental moments...

A combined experimental-theoretical study of silver(I) and silver(II) fluorides under high pressure is reported. For Ag(I), the CsCl-type structure is stable to at least 39 GPa; the overtone of the IR-active mode is seen in the Raman spectrum. Its Ag(II)F2 sibling is a unique compound in many ways: it is more covalent than other known difluorides, crystallizes in a layered structure, and is enormously reactive. Using X-ray diffraction and guided by theoretical calculations (density functional theory), we have been able to elucidate crystal structures of high-pressure polymorphs of AgF2...

PURPOSE: The purpose of this study was to assess the impact of silver nitrate/fluoride varnish (SN/FV) on care costs. METHODS: A retrospective matched cohort study, using Oregon Medicaid claims (January 1, 2012 to December 31, 2014) for patients younger than 21 years old, compared patients treated with SN/FV to matched patients not treated with SN/FV. The number of services and costs were compared using student's t test and generalized estimating equation (GEE) regression models...

Efficient separation and preconcentration of trace nanoparticulate silver (NAg) from large-volume environmental waters is a prerequisite for reliable analysis and therefore understanding the environmental processes of silver nanoparticles (AgNPs). Herein, we report the novel use of polyvinylidene fluoride (PVDF) filter membrane for disk-based solid phase extraction (SPE) of NAg in 1 L of water samples with the disk-based SPE system, which consists of a syringe pump and a syringe filter holder to embed the filter membrane...

Purpose: Silver diamine fluoride (SDF) is an inexpensive, non-invasive, antimicrobial liquid used to treat carious lesions and decrease sensitivity. The purpose of this study was to assess the perceptions of registered dental hygienists in alternative practice (RDHAP) regarding the use of SDF to treat dental caries.Methods: A 16-item survey designed to evaluate RDHAP's familiarity and perceptions of SDF was electronically distributed to 222 RDHAPs practicing in the state of California. A survey research software program collected and tabulated responses, calculated response frequencies for each survey item, and determined statistical relationships among variables, using cross tabulation analysis...

Root caries lesions (RCLs) are highly prevalent in elderly and can negatively impact the quality of life. Therefore, preventive therapies should be applied to control or to arrest RCLs. This chapter will discuss the application of fluoride, a conventional preventive therapy, to control RCLs. Among the self-applied products, there is strong evidence that 5,000 ppm F toothpaste is more effective in arresting RCLs (by increasing hardness) and in preventing new lesions (PF of 51%) compared to 1,100-1,450 ppm F toothpastes, in 6-month clinical trials...

A novel strategy for the synthesis of arylsulfur pentafluorides by silver carbonate-induced Cl-F exchange fluorination of arylsulfur chlorotetrafluorides is reported. This fluorination does not require any exogenous fluoride sources. Rather, the reaction proceeds via the self-immolation of the substrate Ar-SF4Cl.

Boron subphthalocyanines (SubPcs) are powerful chromophoric heterocycles that can be synthetically modified at both axial and peripheral positions. Acetylenic scaffolding offers the possibility of building large, unsaturated carbon-rich frameworks that can exhibit excellent electron-accepting properties, and when combined with SubPcs it presents a convenient method for preparing interesting chromophore-acceptor architectures. Here we present synthetic methodologies for the post-functionalization of the relatively sensitive SubPc chromophore via acetylenic coupling reactions...
