Abstract: A new endodontic machine (Endox Endodontic System) used to vaporize the inflamed pulp tissue was recently introduced in the markets. The high frequency current generated by this machine was tested on extracted human teeth to see whether or not it could cause damage to the dentin structure. It was compared to the Nd: YAP laser machine. Twenty freshly extracted human teeth were mounted in batty silicon and plaster of Paris, respectively, before starting the experiment. The crowns were cut off at the cementoenamel junction and theworking length was determined. Theywere divided into two groups (10 each for every machine). In addition, four teeth with no treatment were used as control. The teethwere sectioned sagitally at the end of the experiment and the root canals were examined with the scanning electron microscope. The results revealed that the smear layer was totally removed by the two machines. The Endox machine did not cause any damage to the dentin structure, whereas the laser caused severe damage. It was concluded from this study that the use of Endox System causes no detectable harm to the dentin structure of the root canal system compared to the laser therapy.
