CARIES, PLAQUE
High plaque accumulation at the proximal surfaces of posterior teeth can lead to the development of caries and the necessity of dental treatments.The alkasite-based tooth-colored material Cention N (Ivoclar Vivadent, Schaan, Liechtenstein) is considered integrant of a subgroup of RCs. This self-curing restorative, with optional additional light curing, displays a high polymer network density and degree of polymerization over the complete depth of the restoration.Several studies have demonstrated that this alkasite-based material releases acceptable levels of fluoride, calcium, and phosphate.Although several
