Bonding of Composite and Glass-ionomer to Amalgam -

Amalgam restorations of adequate standard and condition can very well be repaired with composite, but there should be provided for extra retention into the amalgam filling as the bond strength alone is not adequate. Glass-Ionomer may also be used for repair at amalgam restoration margins in not stress bearing areas, but as they do not adhere to amalgam, they need enamel and dentine for retention and possible undercuts towards amalgam interface.

Improved micro-tensile strength test reveals key to successful repair of restorations -

A more reliable and less time-consuming test method to evaluate the micro-tensile strength of the repair bond between old and new composites has recently been published. The improved test method is based on studies carried out previously at NIOM.

Light curing procedures – performance, knowledge level and safety awareness among dentists -

The study aimed to investigate dentists’ exposure to curing light and to obtain information about the dentists’ knowledge on practical use and technical features of their curing lights as well as their safety awareness.

Posterior composites and new caries on adjacent surfaces – any association? Longitudinal study with a split-mouth design -

The aim of this longitudinal study was to compare caries incidence in sound approximal surfaces adjacent to newly placed composite restorations with the caries incidence in corresponding surfaces in contralateral teeth without any restorations in contact; and to assess risk factors for dentine caries development on adjacent and control surfaces.

Risk factors for caries development on tooth surfaces adjacent to newly placed Class II composites – a pragmatic, practice based study -

To assess risk factors for caries development on approximal surfaces in contact with newly placed Class II composite restorations.
