Intervention / Comparator Agent

Details |
| Comparator Agent |
38% Silver Diamine Fluoride (SDF) |
The comparator material, 38% Silver Diamine Fluoride (SDF), is a chemical complex composed of silver, ammonia, and fluoride. It is applied to the affected tooth surface using a cotton pellet or micro brush for about 10 seconds, following the same protocol as the other agents. The silver component provides a strong antimicrobial effect, while fluoride aids in remineralization, effectively arresting the progression of dental caries. However, a notable drawback of SDF application is the black discoloration of the treated carious lesion, which may affect the esthetics, especially in anterior teeth. Despite this, it remains one of the most effective agents for non-invasive caries management. |
| Intervention |
5% Nano Silver Fluoride (NSF) |
In this study, the intervention involves the application of 5% Nano Silver Fluoride (NSF), which consists of nano-sized silver particles combined with 5% fluoride. The material is applied to the tooth surface using a cotton pellet or micro brush for approximately 10 seconds on a clean air-dried surface. The nano silver particles exert a potent antimicrobial effect against cariogenic bacteria such as Streptococcus mutans, while the fluoride component promotes remineralization of incipient enamel lesions. This combination is designed to arrest the progression of dental caries effectively without causing discoloration of the treated tooth surface, making it a promising minimally invasive approach for managing early carious lesions in children. |
| Comparator Agent |
5% Sodium Fluoride (NaF) Varnish |
The comparator material, 5% Sodium Fluoride (NaF) varnish, is a conventional fluoride formulation widely used in preventive dentistry. It is applied directly onto the tooth surface using a cotton pellet or micro brush for approximately 10 seconds on a clean, dry surface. The varnish acts as a sustained-release source of fluoride, enhancing enamel remineralization and inhibiting demineralization. Through this mechanism, it helps in preventing the initiation and progression of dental caries, making it a standard and well-established agent in caries control protocols for children. |

Brief Summary

Background: Untreated dental caries in children adversely affects their general health, social well-being, and educational prospects, largely because of poor access to basic oral healthcare. Arresting caries treatment (ACT) has been proposed to manage untreated dental caries in children.
Aims and objectives: The purpose of the present clinical study is to investigate the effectiveness of a new anticaries agent, Nano silver fluoride (NSF), in preventing and arresting caries in children compared with silver diamine fluoride, sodium fluoride varnish, and saline as a control group.
Materials and methods: A total of 120 primary teeth, both maxillary and mandibular, were randomly selected from 100 children aged 4–8 years, which were randomly divided into the NSF experimental group, Silver Diamine Fluoride (SDF), Sodium Fluoride Varnish (SFV) test groups, and Saline control group with 30 in each group. Teeth were clinically assessed, treated, and followed up at 7 days, 1, 3, and 12 months. Caries activity was evaluated using ICDAS II criteria. Pearson’s Chi- square test was used to compare groups across follow-ups.
Results: 66.6% of teeth showed arrested caries within 1week follow up, 90% of decayed teeth showed hard arrested dentine at 3 month to 12 month analysis in the NSF group where as it was 100% in 3 month to 12 month follow up in SDF group and 73.3% in 3 month to 12 month follow up in SFV group, where as saline group proved to be in effective.
Conclusion: The present study proves that SDF emerged as the most effective anticaries agent, followed closely by NSF and presents a non-invasive option for caries arrest and treatment when applied directly to caries lesions.
