title: An in vitro comparison of the sealing ability of materials placed in lateral root perforations.
abstract: The in vitro sealing ability of Tytin amalgam, Ketac-Silver, and Prisma VLC Dycal was compared. Roots of extracted teeth were perforated laterally. After the defects were repaired, the teeth were immersed in dye for 10 days and then sectioned, and the linear extent of dye penetration was measured. Statistical analysis showed that the Prisma VLC Dycal group exhibited significantly less dye penetration than the other two groups (p less than 0.01). No difference was found between the Tytin and Ketac-Silver groups.
