Materials and methods:A total of 30 single-rooted teeth were decoronated at 15 mm from the root apex. Root canal instrumentation using step back technique was done and the specimens were split into two halves using diamond disc. These were embedded in acrylic blocks and sent for testing by Vickers hardness test. The other half … Show more
