Contemporary denture base resins: Part 1.

Unlabelled: Provision of partial and complete dentures constructed from resin is commonplace and a satisfactory outcome requires the consideration of the properties of the resin, the oral tissues and prosthodontic principles. Conventional acrylic resin has been widely adopted as a popular denture base material since the 1930s. In this first of a two-part series, the benefits and shortcomings of acrylic resin are discussed alongside contemporary 'enhancements' to the material which can improve its properties.

Contemporary denture base resins: Part 2.

Unlabelled: Provision of partial and complete dentures constructed from resin is commonplace and a satisfactory outcome requires the consideration of the properties of the resin, the oral tissues and prosthodontic principles. This second of a two-part series examines the advantages and disadvantages of flexible nylon denture base resins, which have found popularity for the provision of partial dentures. Adverse effects of denture base resins are examined and the benefits and shortcomings of softliners are explored.

Adhesives for the restoration of non-carious cervical lesions: a systematic review.

Objectives: To establish whether simplified adhesives (self-etch) are as clinically effective as conventional adhesives (etch-and-rinse) with multiple application steps for treatment of non-carious cervical lesions (NCCLs).

Null Hypothesis: there is no difference in the clinical effectiveness of the four different bonding strategies: Three-step etch-and-rinse; Two-step etch-and-rinse; Two-step self-etch; One-step self-etch for treatment of NCCLs.

Sources: Electronic databases were searched including: Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE.

Clinical applications of preheated hybrid resin composite.

This clinical article describes and discusses the use of preheated nanohybrid resin composite for the placement of direct restorations and luting of porcelain laminate veneers. Two clinical cases are presented. Preheating hybrid composite decreases its viscosity and film thickness offering the clinician improved handling.

Considerations for the selection of a luting cement.

Unlabelled: Selection of a luting material for optimal cementation of indirect restorations requires the consideration of several factors relating to the properties of both the cement and of the restoration. Contemporary restorations (for example, dentine-bonded crowns or resin-retained bridges) often rely on bonding, and advances in dental materials science have resulted in simplified resin systems. Their ease of use and other favourable properties also offer advantages when used for more conventional restorations.
