This review of the failure rates of different orthodontic bonding materials included 80 studies with 34 contributing to the quantitative component. The findings suggest little difference between the self-etch primer and conventional acid-etch primer and a poorer performance for glass ionomer compared with self-cure resin. However the findings should be interpreted cautiously because of the low certainty of the available evidence.

This review looked at whether self-etch adhesive sealants were as effective as traditional acid etching. 5 split-mouth studies were included and they found significantly lower failure rates in the acid etch group. Odds ratio 4.46 (95% CI 1.31, 15.20).

This review of 10 in-vitro studies suggests that bond strength is improved by the use of multi-mode adhesives with prior acid etching only for enamel. This improvement was not seen with mild universal adhesives in dentine.

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.

The application of dental bonding to orthodontics had had a significant impact on with bonded appliances replacing multi-banded systems. With the development of bonding systems there is increasing interest in 1-step systems. These self-etch systems (SEPs) are used by about 30% of American practitioners and are thought to reduce chair-side time. The aim of this [read the full story…]
