Comparative Efficacy of Dental Sealants, Silver Diamine Fluoride, and Nanosilver Fluoride in Pediatric Caries Prevention.

Aims and background: To compare the effectiveness and application of dental sealants, silver diamine fluoride (SDF), and nanosilver fluoride (NSF) in children of the age-group 6-12 years. The study combines quantitative clinical outcomes with qualitative patient feedback, providing a holistic view of these preventive strategies.

Materials and methods: This study employed a mixed-methods approach, combining quantitative data on clinical outcomes with qualitative patient and provider feedback. The study design included pre- and posttreatment assessments to evaluate the effectiveness of each preventive measure. A total of 300 participants were recruited for the study, divided into three groups based on the preventive treatment received: group A-100 participants received dental sealants, group B-100 participants received SDF treatment, and group C-100 participants received NSF treatment. Participants included children aged 6-12 years and adults considered at high risk for caries due to factors such as socioeconomic status, previous dental history, or special healthcare needs.

Results: In group A, there was a significant 75% reduction in caries incidence over the 12-month period. Follow-up examinations indicated that sealants remained intact in 90% of cases. Group B reported an 85% success rate in caries arrest, with most lesions remaining stable. In group C, 82% of carious lesions were arrested, with patients reporting less staining compared to those treated with SDF. Follow-up showed high retention of the treatment's effectiveness. Among patients treated with sealants, 90% expressed satisfaction with the application process and perceived effectiveness. SDF and NSF acceptance in group B, 88% of patients reported comfort with SDF treatment. In group C, 92% expressed a preference for NSF due to reduced staining concerns, indicating a strong acceptance of these newer treatments.

Conclusion: This study confirms the effectiveness of dental sealants, SDF, and NSF in preventing and managing dental caries. As these innovations become more widely adopted, they have the potential to significantly improve oral health, particularly among children and high-risk individuals. Ongoing research is necessary to explore long-term outcomes and the broader applications of these preventive treatments.

Clinical significance: (1) The results support the efficacy of dental sealants, SDF, and NSF as vital tools in preventive dentistry. (2) Sealants continue to be a primary recommendation for children due to their high effectiveness and ease of application. (3) SDF and NSF offer compelling noninvasive options for caries management, particularly beneficial for high-risk populations.
