Etching time and bonding of adhesive systems to dentine of primary teeth

Resin-dentin_interface_indicating_a_hybrid_layer

This review the influence of reducing the etching time on the dentine of primary teeth for bonding with etch-and-rinse and self-etching adhesive systems included 8 laboratory studies. The findings suggest that that reductions in acid-etching and primer application did not impact the immediate bond strength.

Dentine hypersensitivity: lasers v topical desensitising agents

Scanning_electron_micrograph_of_dentin_with_open_dentinal_tubules

This review comparing the effectiveness of lasers and topical desensitising agent treatments for dentine hypersensitivity included 13 studies. None of the studies was at low risk of bias so the evidence is of low-quality and insufficient to draw any conclusions on the superiority of lasers or conventional topical desensitising agents.

Study suggests that use of dentine bonding agents provides the greatest improvement in dentine hypersensitivity at 2 weeks and 6 months

The aim of this study was to evaluate the efficacy of three different interventions (non-desensitising toothpaste, desensitising toothpaste and professionally applied dentine bonding agent) in reducing dentinal hypersensitivity over a 2-week, 3-month and 6-month- period in a dental practice setting. In this practice based study patients adults (18-75yrs of age) with at least one sensitive [read the full story…]
