Quantifying and qualifying surface changes on dental hard tissues in vitro

IntroductionTooth surface loss (TSL) is an increasingly recognised problem. We are therefore seeing an increase in the number and complexity of in vitro studies investigating factors that modify effects at the tooth surface.AimThe aim of this paper is to provide a narrative review that illustrates the more commonly used in vitro methods (both historical and contemporaneous) that are available for measuring surface loss and surface change.Method
