Temperature rise on the surface of 20 extracted human lower anterior roots was recorded during the root canal filling by the Obturation Gutta NT. The rise of temperature was recorded at a point in the apical and cervical of the outer surface of each specimen. The temperature of the outer surface in the cervical gradually rose after the insertion of the Obturation Gutta NT, and erached the highest when the handpiece rotation stopped, and then gradually came down. In the apical, a temperature change was not seen in the earlier stage of the insertion of the Obturation Gutta NT. Yet concerning the handpiece rotation, the temperature rose by degrees. The mean root surface temperature ranged from 0.4℃ in the lateral area to 0.5℃ in the apical area, however, this temperature change should not affect the periodontal tissue.
