“…There were six randomized 11-13,15-19 and two nonrandomized 20,21 clinical trials concerning the primary dentition, 11 randomized 11-13,22-32 and two nonrandomized 33,34 clinical trials concerning the permanent dentition and one controlled 35 clinical trial that combined results for both dentitions. The interventions for the control groups were no treatment, oral health counseling or placebo varnish.…”

Background A panel of experts convened by the American Dental Association (ADA) Council on Scientific Affairs presents evidence-based clinical recommendations regarding professionally applied and prescription-strength, home-use topical fluoride agents for caries prevention. These recommendations are an update of the 2006 ADA recommendations regarding professionally applied topical fluoride and were developed by using a new process that includes conducting a systematic review of primary studies. Types of Studies Reviewed The authors conducted a search of MEDLINE and the Cochrane Library for clinical trials of professionally applied and prescription-strength topical fluoride agents—including mouthrinses, varnishes, gels, foams and pastes—with caries increment outcomes published in English through October 2012. Results The panel included 71 trials from 82 articles in its review and assessed the efficacy of various topical fluoride caries-preventive agents. The panel makes recommendations for further research. Practical Implications The panel recommends the following for people at risk of developing dental caries: 2.26 percent fluoride varnish or 1.23 percent fluoride (acidulated phosphate fluoride) gel, or a prescription-strength, home-use 0.5 percent fluoride gel or paste or 0.09 percent fluoride mouthrinse for patients 6 years or older. Only 2.26 percent fluoride varnish is recommended for children younger than 6 years. The strengths of the recommendations for the recommended products varied from “in favor” to “expert opinion for.” As part of the evidence-based approach to care, these clinical recommendations should be integrated with the practitioner's professional judgment and the patient's needs and preferences.

“…The efficacy of topical fluorides in general and fluoride varnishes in particular in reducing dental caries has been extensively documented [2, 16–18]. Since the advent of the first varnishes, researchers have strived to improve both efficacy and delivery of fluorides in varnishes [3, 10, 13].…”

Aim. The aim of this study was to compare the effect of pH cycling on the microhardness of the enamel of primary human teeth treated with a conventional brown Sodium Fluoride (5% NaF) Varnish to those treated with a white Fluoride Varnish (5% NaF) enhanced with functionalized tricalcium phosphate (fTCP). Materials and Methods. Ninety extracted caries-free primary incisors were washed in a detergent and divided into three groups; group A received no treatment, teeth in group B were coated with Sodium Fluoride (5% NaF) Varnish, while teeth in group C were coated with 5% NaF varnish enhanced with functionalized tricalcium phosphate (fTCP). After ten days of pH cycling, the surface microhardness of the teeth was measured using a Knoop indenter. Results. The mean Knoop hardness number (KHN) of 5% NaF with fTCP was greater than that of 5% NaF alone while the control group had the lowest mean KHN. Conclusion. The results of this study suggest that the use of an additive such as fTCP to a fluoride varnish significantly improves the protective ability of the varnish on primary teeth in vitro.

“…Tactile examinations, with radiographs, found caries reductions of 56% in the occlusal fissures of first permanent molars following biannual applications of Duraphat and quarterly examinations. Other randomised clinical trials [Clark et al, 1985;Tewari, 1990, Bravo, 1997] also showed reduced levels of caries of 25-73% following twice-yearly Duraphat applications. These were typical of the studies included in the Cochrane review undertaken by Marinho [2002].…”

A Cluster Randomised Controlled Trial to Evaluate the Effectiveness of Fluoride Varnish as a Public Health Measure to Reduce Caries in Children

This cluster randomised controlled study assessed the effectiveness of twice-yearly applications of fluoride varnish as a public health measure to reduce dental caries in children living in relatively deprived communities. The test (n = 334) and control (n = 330) children in 2 school years (unit of randomisation) attended 24 state primary schools and were 6–8 years of age at the start. Good baseline balance was found. Duraphat varnish was applied at school on 5 occasions over 26 months, by dental therapists. A combined visual and fibre-optic transillumination examination included all surfaces of primary and first permanent molars at baseline and after 26 months for small and large enamel and dentine lesions. At the final examination the only statistically significant difference was in the caries increment for small enamel lesions in the primary dentition, with the test children having fewer lesions. This study failed to demonstrate that the twice-yearly application of fluoride varnish provided at school reduced dental caries in children living in this community. The low level of response and a lower than expected caries increment had a major impact on the effectiveness of the intervention, since the children who participated were least likely to have benefited from the programme, whereas those who might have benefited did not consent.
