Abstract


Aims: The aim of this study is to evaluate increases in temperature on the external root surface during endodontic treatment with different rotary systems.
Materials and Methods: Fifty human mandibular incisors with a single root canal were selected. All root canals were instrumented using a size 20 Hedstrom file, and the canals were irrigated with 5% sodium hypochlorite solution. The samples were randomly divided into the following three groups of 15 teeth: Group 1: The OneShape Endodontic File no.: 25; Group 2: The Reciproc Endodontic File no.: 25; Group 3: The WaveOne Endodontic File no.: 25. During the preparation, the temperature changes were measured in the middle third of the roots using a noncontact infrared thermometer. The temperature data were transferred from the thermometer to the computer and were observed graphically. Statistical analysis was performed using the Kruskal–Wallis analysis of variance at a significance level of 0.05.
Results: The increases in temperature caused by the OneShape file system were lower than those of the other files (P < 0.05). The WaveOne file showed the highest temperature increases. However, there were no significant differences between the Reciproc and WaveOne files.
Conclusions: The single file rotary systems used in this study may be recommended for clinical use.

Key words: Infrared thermometer, one file systems, reciprocating motion, root canal preparation, rotational motion
