Water sorption of dental resin composites: Is a new method the future?

European Journal of Oral Sciences, EarlyView.
Abstract Intraoral, diffusion‐controlled water sorption leads to dimensional expansion and mechanical degradation over time. Measurement of small quantities of water in dental resin composites (RCs) is challenging, as current techniques rely on weighing approaches. Here, we evaluate Karl‐Fischer Titration (KFT) and thermogravimetry (TG) as alternatives
