Amalgam still an effective filling material for posterior teeth


Amalgam has been used for filling teeth for around 150 years. Over that time amalgam restoration have been shown to be a predictable, successful and cost effective.  Concerns regarding aesthetics and their mercury content together with improvement in tooth-coloured dental resin cements have seen a decline in their use.  Recently the Minamata Convention on Mercury [read the full story…]

Currently no evidence to support repairing or replacing resin composite fillings for adults


Over the past 30 years there has been an increase in the use of tooth-coloured composite resin filing materials as an alternative to amalgam for restoring posterior teeth.  Recent technical and material developments have improved the limitations of the early materials which were more likely to fail because of shrinkage, loss of form poor wear [read the full story…]

No evidence to support or disprove the effectiveness of antibacterial agents in composite into fillings to prevent further caries


This is an update of a Cochrane review first published in 2009.  The aim of the review was to assess the effects of antibacterial agents incorporated into composite restorations for the prevention of dental caries. Searches were conducted in the Cochrane Oral Health Group’s Trials Register the Cochrane Central Register of Controlled Trials (CENTRAL) Medline, [read the full story…]

No difference in survival of mandibular lingual orthodontic retainers placed with chemically and light-cured adhesives


Long-term stability following orthodontic treatment required long-term retention. Compliance with removable retention regimens is variable so some practitioners favour fixed retainers.  The aim of this study was to compare the survival of mandibular lingual retainers placed using either chemical or photo polymerization after orthodontic treatment. Patients who had completed orthodontic treatment with no active caries, [read the full story…]

No differences seen in marginal quality of the microhybrid composite restorations placed with regular and high-power polymerisation protocols at five years


Composite resin restorations are becoming a regular element of restorative dental care.  Usually they are photo-polymerised, and polymerization protocols are considered to be one potential factor in the marginal quality of these restorations.  The aim of this study was to compare the marginal quality of composite restorations employing two polymerisation protocols, namely regular versus high [read the full story…]
