Description

Application

• Varying 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) level improves polymerisation kinetics and flexural strength in self-adhesive, remineralising composites.: This research examines the effects of varying levels of a methacrylate in composites that could incorporate poly(propylene glycol) dimethacrylate, affecting their polymerization kinetics and mechanical properties, important for dental material applications (Delgado AHS et al., 2021).
• Poly(propylene glycol) and urethane dimethacrylates improve conversion of dental composites and reveal complexity of cytocompatibility testing.: This study focuses on the role of poly(propylene glycol) dimethacrylate in dental composites, enhancing their conversion rates and highlighting the complexities involved in testing their biocompatibility (Walters NJ et al., 2016).
