Evaluation and Comparison of Three Chemical Agents with a New Herbal Agent for Disinfection of Gutta-percha Cones: An in vitro Study

Abstract Introduction The main aim of this study was to compare and evaluate different chemical agents and herbal products in disinfecting gutta-percha (GP) cones through an in vitro study. Materials and Methods For this study, 160 GP cones were taken in test tubes, which were contaminated with Enterococcus faecalis inocula, prepared by dissolving it in Brain Heart Infusion (BHI) broth. The GP cones were then taken from the test tubes and dried on Whatman filter paper no. 1 and were divided into four groups according to the decontaminant used for the study—group 1 (5% sodium hypochlorite [NaOCl]), group 2 (2% chlorhexidine), group 3 (propolis), and group 4 (Aloe vera)—which were further subdivided into subgroups on the basis immersion time periods of 1 and 10 minutes. The GP cones were then again dried and taken in the test tubes containing freshly prepared BHI broth to check the turbidity. Results It was found that 2% chlorhexidine was the most effective disinfectant against E. faecalis, 5% NaOCl was the second best disinfectant followed by propolis, while Aloe vera had not shown any effect as GP disinfectant. Conclusion Since 2% chlorhexidine showed better disinfection efficacy against E. faecalis than 5% NaOCl, it can be recommended for chairside disinfection of GP. One-minute immersion of GP in 2% chlorhexidine is sufficient for elimination of E. faecalis.

The Difference

Aim:Endodontic retreatment is a procedure that removes the lling materials from the root canals followed by their cleaning, shaping and obturation. This in-vitro study aimed to compare and evaluate the ability of various essential oils as solvents in dissolving gutta-percha, epoxy resin, and zinc oxide eugenol (ZOE) cements. Materials and methods: A total of 28 cylindrical specimens in each group ZOE, epoxy resin, 28 ISO size 40 gutta-percha cones were prepared and divided into four groups for immersion in the different solvents, i.e. lemon oil, citronella oil, lavender oil, and TCE(Tetrachloroethylene (control)) for 5 minutes. The obturating materials dissolution in the solvents were obtained by the difference between the pre-immersion original weight and the post-immersion weight on a digital analytical scale. Data were statistically analysed by a paired t-test and Analysis of Variance (ANOVA) (p < 0.05). Results: Order of efcacy of dissolution of essential oils was found to be lemon oil > Citronella oil > Lavender oil and was highly signicant (p < 0.01). In all the solvents, Gutta-percha showed maximum dissolution (Fvalue:149.56) followed by ZOE(89.07 ) and resin sealer least (23.86). Conclusion: It can be concluded that the lemon oil can be used as a solvent for dissolving obturating materials.
