A novel methodology based on contact angle hysteresis approach for surface changes monitoring in model PMMA-Corega Tabs system

► Contact angle hysteresis (CAH) with inclined plate on Corega/PMMA were measured. ► CAH Chibowski's approach was used to determine wettability parameters. ► Wettability variation was attributed to exposure time and polarity of liquids. ► It stands a tool for tracing surface erosion of dentures cleanser-treated.
