DENTAL CARIES, CARIES
In this study, the use of an alternative application technique for the application of (APF) has been shown to be effective in maintaining healthy surfaces over 24 months.Different caries preventive program strategies were carried out in many countries to decrease caries prevalence and incidence [Fluoride varnishes stand out in preventing dental caries, and are widely accepted by paediatric patients, especially for children under 6 years of age. Fluoride varnishes are widely used and indicated to control caries in children [The fluoride gel/varnish applications are effective and the costs are offset in respect to restorative treatments taking into account that varnishes cost more but are more effective than gels [The present trial underlines that the use of APF on toothbrush provided better results than NaF varnish. This approach not only would be more economical than NaF varnish but also than the use of APF with trays.Studies with supervised toothbrushing programs of up to 5 years show effectiveness especially in high-risk groups. In addition, a partnership with parents and oral care and nutrition counselling are essential to the success of the intervention [A systematic review compared topical fluoride treatments with follow-up of at least one year and frequency of application. This study reaffirmed that the preventive effect of high fluoride gel on primary dentition has strong scientific evidence and is more effective when compared to permanent dentition [Urquhart et al. [As was expected, occlusal surfaces had worse survival than other dental surfaces. Evidence indicates that fissure sealants have been shown to be the most effective strategy in preventing occlusal caries in children and adolescents [Some limits of the study design need to be underlined. First of all, the study population belonged to an age range, in which it was difficult to find a complete compliance and this might have affected the dropout. The number of subjects and the inclusion criteria do not allow us to generalize the results to the general population of this age group.However, this trial presents significant strengths such as the long period of follow-up and the study design.The main clinical significance of the trial is that the results might allow paediatric dentists and health authorities to select the new procedure as an active therapeutic agent to reduce dental caries.
