Evaluate the Arresting effect of 1-step (SDF only) versus 2-step (SDF+KI) application.\n2. Explore the effectiveness of SDF compared to SDF+KI on oral Microbiome.\n3. Evaluate and compare saliva composition before and after SDF application. Study Question What is the clinical and laboratory impact of silver diamine fluoride application in caries-active children? Research Null Hypothesis\n\n\u003C!-- -->\n\n1. There is no difference in the Arresting effect of SDF versus SDF+KI application.\n2. There is no difference between the effectiveness of SDF versus SDF+KI application on oral Microbiome.\n3. There is no difference in in saliva composition before and after SDF\n\nResearch protocol:\n\nMaterials and methods The study will be conducted at the Department of Pediatric Dentistry, Faculty of Dentistry, King Abdul Aziz University, after approval from the University Institutional Ethics Committee.Informed consent will be obtained from the participant\\'s parent. The sample will be collected, and sent to King Fahd Medical Research Center\n\nPatients' enrollment An informed consent document will be obtained from those participant parents willing to be part of the trial before the study start. A brief interview-based survey will be conducted about general and dental health, oral hygiene, sugar consumption, and family demographics. A calibrated pediatric dentist will do dental examinations and lesion evaluations, followed by sample collection.\n\nBiospecimens collection protocol:\n\n* All participants will be required to fast for 90 minutes prior to specimen collection.\n* All participants will be seated in an upright position in the dental chair.\n* Sample will be collected in the first visit for all children, and another set of samples will be collected again for children recruited in the second part of the study.\n* Each child will have an oral swab, saliva, supragingival plaque, and subsurface dentine obtained. The collection will be conducted in the following manner:\n\n  1. Saliva sample ▪ Unstimulated saliva (S, Saliva) will be obtained from enrolled children. using a standardized Spitting method\n\n     ▪ Approximately 5 ml of un-stimulated saliva will be collected using 50 ml falcon tube\u002F specimen container.\n\n     ▪ Collected saliva will transferred and stored in an Eppendorf tube using 5-10 ml syringe.\n  2. Biofilm samples\n\n     ▪ Biofilm samples will be collected from both teeth with and without Carious surfaces.\n\n     ▪ Sterilized Microbrush\u002Fpaper points will be used for collection of dental plaque\n  3. Subsurface carious dentin ▪ Sample collection from within the extensive untreated caries (at baseline visit) ▪ Sterilized dental excavators and sterilized large round bur will be used for sample collection▪ Subsurface carious dentin excavation utilizing a spoon excavator and round bur to extract carious dentin tissue (1.0 to 1.5 mm of depth) Collection and storage procedure The sample will be collected from recruited children at the first visit (as the baseline).\n\nA sterilized dental instrument will be used for the collection of samples, The samples will be stored in Eppendorf tubes filled with 200LμL of phosphate-buffered saline (PBS) solution. Before laboratory analysis, all gathered samples will be kept in a freezer at - 80 °C.\n\nClinical trial PICO:\n\nP: Children aged 2-10 years caries-free or with caries- active (with at least 1 tooth with deep cavitated lesions (with no signs of pulpitis)) I: Management using SDF (Silver diamine fluoride 38%) C: Management using a different fluoride containing product (SDF 38%+KI) O: Alteration in metabolomics and microbiome.\n\nPatients' enrollment At the first visit, children with active dental caries will undergo a sample collection process conducted by a calibrated pediatric dentist who will also provide the intervention treatment during the same session (baseline visit). A second sample collection appointment will be scheduled after two to three weeks, followed by another follow up visit after two-week.\n\nStudy groups:\n\n* Experiment group The intervention participant will receive silver diamine fluoride 38%\n* Comparison group The Comparison participant will receive SDF+KI system. Intervention A calibrated pediatric dentist will perform the procedures. Saliva and plaque sample will be collected on completion of SDF application.\n\nSample collection:\n\n* Sample collection will be conducted Before, 2 and 4 weeks after Intervention.\n* The sample included are saliva, supragingival and occlusal plaque, caries plaque (Carious and SDF-treated surfaces), and subsurface carious dentin (from within the carious untreated lesion)▪ Plaque Sample of supragingival and occlusal plaque will be collected from primary and permanent teeth. Outcomes The primary outcome measure will be the difference in microbiome groups over time and the difference within the treatment groups. The secondary outcome will be the effect on salivary metabolomics.\n\nAssessment will include:\n\n1\\. The microbial community composition of surface biofilm prior to and post SDF treatment.\n\n2\\. Subsurface microbiota and microbial community composition prior and post SDF treatment.\n\n3\\. Comparing the microbial community composition of dentin\\'s subsurface microbiota after treatment with SDF and SDF+KI. 4. Salivary metabolomics before and after SDF Statistical Analyses Continuous data will be reported as means and standard deviations, whereas categorical variables will be presented as frequencies and percentages (SD). Statistical significance across groups will be determined using either a one-way analysis of variance (ANOVA) model or the non-parametric version of the Kruskal-Wallis test, depending on whether the variables are normally distributed. Using R, taxonomy plots and tables will be generated, and relative abundance at different taxonomic levels and microbial diversity indices will be calculated. Between the groups, relative abundance and alpha and beta diversity parameters will be evaluated. In addition, the relationship between caries activity, caries risk factors, clinical features, and microbiota composition will be studied prior to and following intervention. Statistical significance will be regarded when p-values are less than 0.05, and P-values in multiple comparisons will be adjusted for the false discovery rate (FDR). Expected Findings:1. There is a difference in the clinical and microbial effect of SDF versus SDF+KI application on oral microbiome 2. There is a shift in saliva composition before and after SDF.",[31,37],{"label":32,"type":33,"description":34,"interventionNames":35},"Arresting Treatment 1","ACTIVE_COMPARATOR","Management of dental caries in children between the ages of 4 and 10 by arresting the lesion using standard Treatment for caries arrest, which is silver diamine fluoride %38",[36],"Drug: Silver diamine Fluoride 38%",{"label":38,"type":39,"description":40,"interventionNames":41},"Arresting Treatment 2","EXPERIMENTAL","Management of dental caries n children between the ages of 4 and 10 by arresting the lesion using an alternative Treatment by using the combination of Silver diamine fluoride 38% + potassium iodide (SDF+KI), Both products reported as materials with an anti-microbial effect",[42],"Drug: Silver diamine fluoride- potassium iodide",[44,52],{"type":45,"name":46,"description":47,"armGroupLabels":48,"otherNames":49},"DRUG","Silver diamine Fluoride 38%","Intervention is the application of Silver diamine fluoride 38% to children Group in arm 1 (Arm 1): children will receive Silver diamine fluoride 38% application for 1 min to arrest primary teeth\n\nSDF: (Silver diamine fluoride 38% is a material used for arresting caries lesions in primary and permanent teeth)\n\n\\- SDF Product generic name and information (E-SDF: it is a 1-step Technique) -
