Sealants or fluoride varnish for caries prevention?

Fissure sealant

This Cochrane review update included 8 trials involving 1746 participants. Some low-quality evidence suggesting the superiority of resin-based fissure sealants over fluoride varnish applications was identified

This review included 13 small studies of limited quality. While the available evidence suggests there may be no difference, further long-term high quality studies are required to confirm if this is the case.

Review finds glass ionomer had lowest annual failure rate in non-carious cervical lesions

shutterstock_17187229

Non-carious cervical lesions (NCCLs) are saucer or wedge-shaped defects that appear along the cementum-enamel junction as a result of gradual loss of dental tissues in the absence of caries. Their aetiology has not been fully clarified. NCCLs are restored using adhesive materials glass-ionomers and their resin-modified version, poly-acid modified composites (known as ‘compomers’), composite and [read the full story…]

Study suggests benefits to adjacent teeth from application of fluoride containing fissure sealants

shutterstock_80298358

There is good quality review evidence (Ahovuo-Saloranta et al.  2013) that resin-based fissure sealants are effective at preventing or controlling occlusal caries. The aim of this trial was to assess whether sealing first permanent molars with fluoride releasing compounds reduced the caries increment on the distal surface of the second primary molars. Children with at [read the full story…]

Review suggests that glass ionomers had best retention rates in non-carious cervical lesions

shutterstock_6838084

The aetiology of non-carious cervical lesions  (NCCLs) has not been fully clarified but they are characterised by a slow and gradual loss of mineralized dental tissue in the absence of dental caries. This results in a saucer or wedge-shaped defect that appears along the cementum–enamel Junction.   The aim of this review was to assess the [read the full story…]

Atraumatic restorative treatment had good 1-year survival and cost effectiveness in older adults

shutterstock_40173181

The proportion of older people in the population is rising and because of improvement in oral health more of them as retaining their teeth. Consequentially more people in this age group will have more teeth at risk of caries. Dental service utilization is also lower in older age groups and chronic medial conditions; poly-pharmacy, frailty [read the full story…]

Atraumatic restorative treatment had similar survival rates to conventional approaches in primary teeth but evidence limited

shutterstock_92524393

Atraumatic restorative treatment (ART) involves the removal of so softened carious enamel and dentine with hand instruments and filling the cavity with a adhesive restorative material. Typically this is a high-viscous glass ionomer cement (GIC).   This approach was about 25 years ago  to provide care in less industrialised areas with high disease levels but is [read the full story…]

Critical summaries from the American Dental Association Center for Evidence-Based Dentistry

Two new critical summaries are now available at the ADA-EBD site The first one is of a 2011 review by  Yengopal and Mickenautsh; The aim of the review was to assess whether resin-modified glass-ionomer cement (RM-GIC) offered a significant caries-preventive effect compared with resin-based composite (RBC)? The appraiser generally considers the review to be well [read the full story…]
