Silver diamine fluoride (SDF) is a potential preventive agent that can prevent caries progression in children. This systematic review examined the effectiveness of silver diamine fluoride in arresting caries compared to other fluorides. An electronic search of MEDLINE, PubMed, EMBASE, Cochrane, Web of Science, Scopus databases was carried out examining articles in English from 2001 to 2023. Studies included in the analysis examined the application of SDF in children and adolescents with coronal caries lesions on primary teeth or permanent first molars. Fifteen studies, involving a total of 7895 children, were incorporated. The application regimen varied across studies. Most studies in this review consistently suggested that SDF is effective in arresting caries. An annual application of SDF effectively reduced <i>Streptococcus mutans</i> count. Adverse effects were primarily tooth staining and less commonly, oral mucosal irritation. A majority of studies showed a high risk of bias due to methodological insufficiencies. Overall, the evidence suggests that SDF is effective in arresting dental caries in children. It offers a viable, cost-effective, and minimally invasive treatment option, particularly suitable for use in low-resource settings. However, the aesthetic concern of tooth staining with SDF use remains a challenge. Further well-designed clinical trials may provide a fuller picture of SDF which can shape public health policy and shift towards a minimally invasive treatment approach.</p>","PeriodicalId":50235,"journal":{"name":"Journal of Clinical Pediatric Dentistry","volume":"48 5","pages":"27-40"},"PeriodicalIF":1.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142299889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The remarkable expansion of 3D printing necessitates a comprehensive examination of its status and applications in the dental field, particularly in the pediatric dentistry. This review provides a comprehensive exploration of the applications of 3D printing in pediatric dental practices by drawing from a systematic search across databases, including PubMed/MEDLINE, Scopus, Web of Science, Scielo and the Cochrane Library. The search strategy employed a combination of keywords: \"Digital dentistry and 3D printing\", \"3D printing technology in dentistry\", \"3D printing in pediatric dentistry\" and \"3D printing in pediatric dental procedures\". The review encompasses a wide array of studies, including original research, cross-sectional analyses, case reports and reviews. A detailed overview is presented in regard to the use of 3D printing for master and educational models, space maintainers, prosthetic restorations, surgical guide, splint design and fracture treatment, fluoride application, autogenous dental transplantation, anterior teeth restoration, and pediatric endodontics and regenerative treatments. This review shows that 3D printing improves clinical outcomes through personalized and precise treatment options and enhances dental students' educational landscape. Areas lacking extensive research were also identified, which warrent further investigation to optimize the integration of 3D printing in pediatric dentistry.

The aim of this study was to evaluate the nanohardness, elastic modulus and surface roughness of the fluoride release of tooth-colored restorative materials after immersion in acidic beverages. Prepared samples of three restorative materials (a highly viscous glass ionomer (EQUIA Forte; GC, Tokyo, Japan), a compomer (Dyract XP; Dentsply, Weybridge, UK), and a bioactive restorative material (Activa BioACTIVE; Pulpdent, MA, USA)) were randomly divided and immersed in distilled water, a cola and an orange juice for one week. The HYSITRON T1 950 TriboIndenter device (Hysitron, USA) with the Berkovich diamond indenter tip was used for all measurements. The nanohardness and elastic modulus of the samples were measured by applying a force of 6000 μN to five different points on the sample surface. Surface roughness measurements were evaluated on random samples by scanning five random 40 × 40 μm areas. The properties were measured at the initial and one week after immersion. The values of nanohardness, elastic modulus and surface roughness were tested for significant differences using a two-way analysis of variance (ANOVA) with repeated measures (<i>p</i> < 0.05). Tukey's honest significant difference (HSD) test was used for multiple comparisons. AB (Activa BioACTIVE) had the highest initial mean values for nanohardness. After post-immersion, the highest mean value for elastic modulus was the initial AB value. The lowest mean value for roughness of 100.36 nm was obtained for the initial DX (Dyract XP) measurement.
