Objectives
The study aimed to assess and compare micro-shear bond strength (µSBS) to dentin, micromorphological and chemical changes of newly introduced bioactive restorative materials/dentin interfaces.
Materials and methods
Total of 56 molars were used in this study, for μSBS, 28 molars (n=28) were randomly assigned into 4 groups (n=7) according to the type of restorative material used: group A; Activa, Pulpdent, group B; Beautifil II LS, Shofu, group C; Cention N, Ivoclar Vivadent and group D; Surefil one, Dentsply Sirona. The other 28 molars (n=28) were tested for elemental analysis of restoration/tooth interface using EDX and micromorphological analysis under SEM, …
