One-step self-etch adhesive, Adhese One F

A new one-step self-etch adhesive, Adhese One F, manufactured by Ivoclar Vivadent has been sent to the Santini Miletic Research Group for scientific evaluation. The adhesive is based on previously developed Adhese One with the inclusion of potassium fluoride which is reported to act as a fluoride releasing agent. The manufacturer's internal data state that there is a cumulative fluoride release over a 6 day period.

Micro-Raman spectroscopic studies will be conducted to evaluate the ratio of carbon-carbon double bonds (RDB) of Adhese One F under different curing conditions. Furthermore, the adhesive-dentine interface will be characterised in terms of dentine demineralisation and adhesive penetration and the RDB across this interface.

A previous study has shown significantly lower RDB values for Adhese One in both the adhesive and the hybrid layer compared to Excite (etch-and-rinse) and Adhese (2-step self-etch). In another study, Adhese One produced a thinner hybrid layer compared to G Bond (1-step self-etch), Filtek Silorane adhesive system (2-step self-etch) and Excite
