Fissure sealants effective in preventing caries in children and adolescents

Fissure sealant

38 trials were included in this updated Cochrane review of the effect of fissure sealants on occlusal caries. The data show a reduction in caries of between 11-51% at 24months compared to no sealant. The benefit was also maintained at longer-term follow up.

Pulp capping carious exposures in adults: calcium hydroxide or MTA?

900px-Pulp_cap

This small but well conducted RCT compares the effectiveness of MTA and calcium hydroxide for direct pulp capping material in adult molars with carious pulpal exposure finding better performance for MTA at 3 years.

The Cochrane review of of materials for retrograde root filling identified 6 RCTs all at high risk of bias. The trials provide insufficient evidence to draw any conclusion as to the benefits of any one material over another so more high quality studies are needed.

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

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…]
