Background: Although gutta-percha cones are usually supplied in aseptic packages, once opened and used, they may be contaminated. Chair side disinfection of these cones is important and critical for success of endodontic therapy. Gutta-percha being heat labile, chemical disinfection is the only viable alternative for the sterilization of these cones. Aim: The aim of the study was to evaluate an effective method of disinfection of gutta-percha cones using various herbal and chemical solutions after intentional contamination with Staphylococcus aureus and Enterococcus faecalis. Materials and Methods: 150 gutta-percha cones were selected for the study. Based on the contaminants used, 140 gutta-percha cones were divided into 2 groups: Group A and Group B with 70 cones in each group and the remaining 10 cones (Group VIII) which were uncontaminated served as negative control. The cones from Group A were contaminated with Staphylococcus aureus (S. aureus) and Group B were contaminated with Enterococcus faecalis (E. faecalis). The contaminated cones from both groups were subdivided into 7 groups with 10 cones in each group. Group I cones were disinfected with Q Mix 2 in 1, Group II with 3% sodium hypochlorite, Group III with chitosan, Group IV with aloe vera juice, Group V with amla juice, and Group VI with pancha tulsi. Group VII consisted of gutta-percha cones without any disinfection in both Group A and Group B which served as positive control. The disinfection time was 1 min. All the cones were then incubated in thioglycollate media for 7 days. The thioglycollate media was subcultured and colony forming units were counted. The data were analyzed by one-way ANOVA and post-hoc Tukey tests using SPSS 17.0 software. Results: There was a statistically significant difference present in the mean colony forming units among all the groups (P < 0.05). Conclusion: Pancha Tulsi and Q Mix 2 in 1 possessed superior antibacterial activity when compared to other experimental solutions.
