Fluoride Application for Dental Caries Prevention
Introduction to Fluoride Application
Fluoride application is a widely recognized method for preventing dental caries in both children and adolescents. Various forms of fluoride, including gels, varnishes, foams, and mouth rinses, are used professionally to enhance dental health. This article synthesizes recent research findings on the effectiveness of these fluoride applications.
Effectiveness of Professional Fluoride Applications
Fluoride Varnish
Fluoride varnish is one of the most commonly used professional fluoride treatments. Studies have shown that fluoride varnish significantly reduces caries incidence in both primary and permanent teeth. For instance, a review of professionally applied fluorides indicated that both APF gel and fluoride varnish are effective in caries prevention, particularly for high-risk groups and children under six years old, where 2.26% fluoride varnish is recommended . Another study conducted in rural Brazil demonstrated that 5% sodium fluoride varnish significantly reduced caries increments in school children over 12 months, with a preventive fraction of 40% .
Comparison with Regular Fluoride Toothpaste
The additional benefit of professional fluoride application (PFA) over regular fluoride toothpaste (RFT) has been debated. A systematic review and meta-analysis found no significant difference in caries prevention between children using fluoride varnish in addition to RFT and those using RFT alone . This suggests that while fluoride varnish is effective, its additional benefit over regular fluoride toothpaste may be limited.
Silver Diammine Fluoride (SDF)
Silver diammine fluoride (SDF) has also been studied for its effectiveness in arresting dentine caries. A randomized clinical trial found that annual or three consecutive weekly applications of 30% SDF solution were more effective in arresting dentine caries in primary teeth compared to 5% sodium fluoride varnish . This highlights SDF as a potent alternative for managing active caries lesions.
Economic Evaluation of Fluoride Varnish
The cost-effectiveness of fluoride varnish application in preschoolers has been assessed in several studies. While some studies reported fluoride varnish as a cost-effective measure, others found it to be less cost-effective compared to other preventive measures like fluoridated water, sealants, and fluoride toothpaste . This indicates that the economic viability of fluoride varnish can vary based on the context and comparison with other interventions.
Application Procedures in Orthodontic Practice
In orthodontic practice, fluoride application is crucial for preventing caries around braces and other appliances. Recommendations include the use of APF gel before appliance placement and regular recementations, along with daily rinsing with dilute NaF or APF solutions and the regular use of fluoride dentifrice . These measures help in maintaining oral hygiene and preventing caries in orthodontic patients.
Conclusion
Professional fluoride applications, including varnishes and gels, are effective in preventing dental caries in children and adolescents. While fluoride varnish is particularly effective, its additional benefit over regular fluoride toothpaste may be limited. Silver diammine fluoride presents a strong alternative for arresting dentine caries. The cost-effectiveness of fluoride varnish varies, and its application in orthodontic practice is essential for caries prevention. Overall, fluoride applications remain a cornerstone in dental caries prevention strategies.
