Abstract: Background: Enhancement of time and temperature of sodium hypochlorite affects dentin scaffold within the root canal, ultimately leading to fracture. Therefore, the aim of the present in-vitro investigation was to compare the influence of time and temperature of NaOCl on endodontically treated teeth. Materials and Methods: Fifty extracted mandibular premolars were allocated into five groups, ten samples in each group. Access cavities were prepared and root canals were instrumented using a sequence of 4 manual stainless steel files and irrigated with 3% NaOCl solution. The time (5min and 10 min) and temperature (550C and 20C ) of NaOCl varied among each group; group 1- 5min, 550 C; group 2- 5 min, 20 C; group 3- 10 min, 550 C; group 4- 10min, 20 C; group 5- control group. Then all the samples were subjected to compressive load by means of hydraulic universal testing machine until fracture of the specimens. Result: The fracture strength of specimens in the experimental groups was significantly lower than the control group (p<0.001). Conclusion: Preheating of sodium hypochlorite at 550 C and contact time of 10 minutes provided better fracture strength (group 3).
