This split-mouth trial conducted in 4-5 year old children found that sealants were superior to fluoride varnish applications in preventing the development and progression of caries in occlusal surfaces of primary molars over 1 year.

The Scottish Intercollegiate Guidelines Network (SIGN) have just launched a new guideline on caries prevention in children. The guideline replaces two existing guidelines; SIGN 47 on preventing dental caries in children at high caries risk and SIGN 83 on prevention and management of dental decay in the pre-school child. The guideline was developed using SIGN [read the full story…]
The effectiveness of fluoride varnishes for caries prevention for children and adolescents is well established with the recent update of the Cochrane review (Marinho et al 2013) estimating the pooled preventive fraction of 43% (95% CI 30-75%) for permanent teeth and 37% (95% CI 24-51%) for primary teeth. However although 22 trails were included there [read the full story…]
The development of early, but reversible, carious lesions or demineralised white lesions (DWLs) is one adverse effect of fixed appliance orthodontic treatment. The prevalence has been reported to be as high 70%, and although the majority are minor and fade with time as they resolve about 10% cavity and may require filings. The main aim [read the full story…]
In 2006 the American Dental Association (ADA) published recommendations regarding professionally applied topical fluorides. An update of these guidelines has just been published. An executive summary is available from the Journal of the American Dental Association and the full report can be downloaded from the ADA – Centre for Evidence-based Dentistry (ADA-EBD) website (see links).

Varnishes have been is use as a delivery system for topical fluoride since the 1960s. Their effectiveness was highlighted to a greater extent following the publication of the first version of this Cochrane review in 2002. Since then use of fluoride varnish has been recommended in evidence-based guidance from SIGN, the SDCEP and the American [read the full story…]
There is substantive evidence from systematic reviews for the effectiveness of fluoride varnish (FV) in caries prevention (Marhino et al 2002). The aim of this study (Divaris et al 2012) was to assess whether there were differential effects for FV according to tooth surface and baseline pathology. This was a secondary analysis of a cluster-randomised [read the full story…]
One of the adverse effects of orthodontic treatment is the development of white spot lesions (WSLs). The incidence of these early carious lesions has been reported to vary between 5-97% . The aim of this trial was to effectiveness of MI Paste Plus and PreviDent fluoride varnish (22,600 ppm of fluoride) with a standard oral [read the full story…]
Dental caries is unfortunately still a common problem among children worldwide. Cochrane reviews have shown the effectiveness of pit and fissure sealants (Hiiri et al 2009) and fluoride varnishes (Marinho et al 2002) . While other reviews have found silver diamine fluoride (SDF) to be effective (Rosenblatt et al 2009). The aim of this trial [read the full story…]
We recently reported on a other fluoride varnish study in a similar age group conducted in the UK. The aim of this study was to determine the efficacy of 5% sodium fluoride (NaF) varnish application in reducing caries increments in the permanent dentition of rural Brazilian school children over the course of 12 months. Children [read the full story…]
