The release of Bisphenol-A (BPA) from dental resins has attracted attention from researchers, and it has been described as an endocrine disruptor chemical. The aim of this review was to assess the short- and long-term release of BPA in human tissues (saliva, blood serum and urine) after treatment with dental pit and fissure sealants. Searches [read the full story…]
This latest critical summary prepared under the auspices of the ADA Center for Evidence Based Dentistry looks at a 2012 meta-analysis by Kühnisch et al that looks at the retention rates of pit and fissure sealants. The results of the meta-analysis suggest that resin-based sealants have the highest retention rates at 5-years. The appraiser notes [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…]
Dental caries is a chronic disease that usually progresses slowly. The demineralisation of the tooth seen in the early stages of dental decay are reversible so progression to cavitation can be prevented. The aim of this review was to appraise the evidence for the efficacy of nonsurgical caries preventive methods to arrest or reverse the [read the full story…]
Fissure sealants have been available since the 1960’s and a 2008 Cochrane review by Ahovuo-Saloranta et al highlighted their effectiveness for preventing occlusal caries noting that their effectiveness is obvious in high caries risk children. The aim of this new study by Muller-Bolla et al, was to assess their effectiveness in a school-based dental sealant [read the full story…]
There is a tendency to focus on the prevention of dental caries in children yet is it is a problem that continues to affect old and young alike. While considerable time and effort is spent on preventive programmes for children far less consideration to adults. The American Dental Association Center for Evidence-Based Dentistry has published [read the full story…]
An increasingly elderly population have benefited from improvements in oral health care resulting in the retention of an increasing number of natural teeth. This brings the challenge of maintaining these teeth and their replacements in good disease free condition. However, studies indicate that oral health in this group is often poor. The aim of this [read the full story…]
The aim of this trial was to test the use of motivational interviewing (MI) as an approach to control caries in indigenous children. This cluster-randomised trial was conducted in Cree communities in Quebec. Cree women who recently had given birth or were between the 12th and 34th weeks of pregnancy were recruited. Mothers allocated to [read the full story…]
There has been a recent surge of interest in use of sliver-fluoride regimens for caries control as sadly dental caries is still a significant problem worldwide. The aim of this trial was to compare the effectiveness of annual topical application of silver diamine fluoride (SDF) solution, semi-annual topical application of SDF solution, and annual application [read the full story…]
The possible link between the MMR vaccine and autism has been shown to have no basis in evidence, despite such a link being posited in a 1998 paper in the Lancet. The paper was subsequently retracted following a GMC investigation of its author. The researchers in this US study point out that although the link [read the full story…]
