17 pro- and retrospective studies were included in this anterior composite restoration performance. While low annual failure rates from 0 – 4.1% were found, there is a need for well-designed clinical trials to evaluate the longevity of anterior composite restorations and investigate the specific factors associated with failure.

This trial involving 48 patients found that EDTA conditioning improved the retention of restoration in non-carious cervical lesions at 18 months.

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.

8 studies were included in this review comparing amalgam with composite in posterior restorations. There was a statistically significant benefit in favour of amalgam for both restoration failure and secondary caries.

The number of non-carious cervical lesions (NCCLs) that will require management in the future is expected to increase. This review was only able to identify 4 RCTs looking at whether bevelling the enamel margin improves retention, so there is limited evidence for the clinician.

This review of direct anterior restorative materials included 21 studies and covered a wide range of materials and adhesive systems. Overall the failure rates were low for both class III and class IV restorations.

This study compared Class II nanohybrid resin composite restorations bonded with a one-step self-etch or a two-step etch-and-rinse adhesive after 8 years, finding no difference between the two approaches.

Only 10 low quality studies were available for this review to assess if a vital pulp restored with composite resin is at greater risk of pulpal complications than one restored with other materials. Questions over the studies qualities make it difficult to draw any conclusions.

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…]
Dental amalgam has been the filing material for choice for more than 150 years. However, because of their aesthetics and concern over their mercury content their use has been declining. The Minamata Convention on Mercury has also proposed that their use be phased down according to local needs. The development of tooth-coloured resin composites from [read the full story…]
