From: Evaluation of Effectiveness of Er,Cr:YSGG Laser For Root Canal Disinfection: Theoretical Simulation of Temperature Elevations in Root Dentin J Biomech Eng. 2009;131(7):071004-071004-8. doi:10.1115/1.3147801 Figure Legend: Heat penetration from the canal surface to the soft tissue region is shown by the increasing temperature along the root-tissue interface with time. Temperatures are plotted along the root-tissue interface (the solid white line in Fig. ) from the apex to the crown. The maximum temperature is lower than the critical temperature of 47°C when the heating time is shorter than 26 s.
