Aim: To evaluate the effect of 5.25% sodium hypochlorite (SH), 90% aloe vera (AV) gel, and 2% chlorhexidine (CHX) as disinfecting solutions on the physical and mechanical properties of gutta-percha (GP). Materials and methods: A total of 80 GP cones of size F3 ProTaper were obtained from sealed packet as four different groups. The experimental groups were disinfected with 5.25% SH, 90% AV gel, and 2% CHX except control group. The tensile strength of GP cones was measured under universal testing machine, and the surface texture was analyzed under stereomicroscope. Results: Mean tensile strength in the order of lowest to highest was 9.13 for 5.25% SH, 13.05 for 2% CHX, 13.56 for 90% AV, and 16.44 for control group. The 5.25% SH group showed pitting on surface and control group and AV group showed negligible pitting, whereas 2% CHX showed moderate pitting on surface under stereomicroscope. Conclusion: Aloe vera gel at 90% can be considered as a safer GP cone disinfectant. Clinical significance: The main objective of root canal treatment depends on the elimination of microorganism from the root canal system. To obtain aseptic condition, disinfection of GP cone is required, which may get contaminated during handling. Aloe vera gel can be a promising herbal disinfecting solution for GP cone without affecting any physical and mechanical properties of it.
