Dental adhesives are needed for the adhesion of resin-based filling materials to the tooth. New dental adhesives have evolved over time to provide faster application techniques and to improve chemistry and facilitate stronger binding. The most recent adhesives are called universal adhesive systems. The universal adhesives may be used either as self-etching adhesives or with the etch-and-rinse technique.
Is there any difference in dentin bond strength for universal adhesives using etch-and-rinse or self-etching mode?
We searched three electronic databases. We only included systematic reviews published in English. We identified 105 articles out of which 10 were considered potentially relevant. One person read these in full text. One systematic review was included in the answer. Primary studies published after the systematic review were listed in the answer.
|Included studies||Experimental setting||Outcome (no of studies)|
|Rosa et al 2015 
|10 in vitro studies.
Universal adhesive used in self-etch and etch-and-rinse mode.
Storage in water for 24 hours before outcome measurement.
Aging by storage 1 year (1 study) or thermocycling (1 study)
|Dentin bond strength: Micro-tensile bond strength (7).
Enamel bond strength: Micro-tensile bond strength (2), micro-shear bond strength (2)
“The enamel bond strength of universal adhesives is improved with prior phosphoric acid etching. However, this effect was not evident for dentin with the use of mild universal adhesives with the etch-and-rinse strategy.”
