Comparative Evaluation Of Cariostatic Efficacy Of 5% Nano silver Fluoride,38% Silver Diamine Fluoride,5% Sodium Fluoride Varnish On Primary Teeth In Children Of Age Group 4 To 8 Years With Incipient Carious Lesions – An In-Vivo Randomized Clinical Trial

Over the past two decades, dentistry has evolved significantly yet dental caries remains a prevalent chronic disease worldwide particularly among children. Factors such as poor oral hygiene dietary habits limited access to care and socioeconomic conditions contribute to its high occurrence. Many cavities go untreated due to the overwhelming demand for oral healthcare services. Minimally invasive cost-effective approaches are replacing traditional drilling and filling methods to arrest caries progression. A shift toward a medical model of caries management focusing on prevention and remineralization is essential. While fluoride-based treatments are widely used they require patient compliance and multiple applications. To address this, the present study aimed to compare and evaluate the cariostatic efficacy of 5% nanosilver fluoride 38% silver diamine fluoride 5% sodium fluoride varnish on primary teeth in children of age group 4 to 8 years with incipient carious lesions an Invivo randomized clinical study. Ethical clearance was obtained from the institutional review board before conducting the study. A total of 160 incipient lesions of primary teeth were included in the study. Children were randomly assigned to one of four groups Group I 5% nanosilver fluoride, Group II 38% silver diamine fluoride, Group III 5% sodium fluoride varnish and Group IV saline served as the control group. After obtaining the consent form from the parents Under a sterile condition topical fluoride application was done to individuals of respective groups. The evaluation of cariostatic efficacy in terms of depth size and sensitivity was assessed in four groups. The results were subjected to statistical analysis. It was observed that the superior efficacy of SDF and NSF in managing dental caries. While SFV offers temporary benefits its long-term efficacy is limited. Saline proved ineffective confirming the need for active intervention. SDF emerged as the most effective agent, followed closely by NSF making these treatments highly recommended for caries management.
