Abstract— Gutta-percha cones should be free of pathogenic microorganisms before being used for root canal filling. This study was canied out to evaluate the effectiveness of four chemical agents in eliminating Bacillus subtilis spores from gutta-percha cones. The solutions tested were 5.25% sodium hypochlorite, 2% glutaraldehyde, 2% chlorhexidine digluconate, and 70% ethyl alcohol. The gutta-percha cones coated with spores were placed into contact with the chemical agents for 1, 3, 5 and 10 min. The results showed that 5.25% sodium hypochlorite was effective in destroying the spores after 1 min of contact. Glutaraldehyde, chlorhexidine and ethyl alcohol did not decontaminate the gutta-percha cones even after 10 min of contact.
