Summary In vitro temperatures produced in the root canal and on the root surface were measured simultaneously as heated gutta‐percha was injected into the prepared canal. The canals were obturated with the Obtura II heated gutta‐percha system with temperature settings of 160, 185, and 200°C. The mean intracanal temperatures ranged from 40.21 to 57.24°C, whereas the mean root surface temperatures were recorded from 37.22 to 41.90°C for all three temperatures tested. The rise in temperature on the root surface was below the critical level of 10°C and should not cause damage to the periodontal ligament.
