Disinfection of gutta-percha cones using three reagents and their residual effects.

Aims And Objectives: The purpose of this study was to compare the efficacy of 5.25% sodium hypochlorite, 2% chlorehexidine and MTAD in disinfecting gutta-percha cones and to analyze the surface topography of gutta-percha cones after the rapid chemical disinfection procedure.

Materials And Methods: Gutta-percha cones were immersed in suspensions of Enterococcus faecalis and Staphylococcus aureus separately.
