AB  - The thermal effects of a CO2 laser on the external root surface and inside the 
      root canal were studied in vitro by means of computerized infrared (IR) 
      thermography and a digital thermometer. One-hundred-and-eighty tooth roots with 
      single root canals were irradiated internally and externally with laser power set 
      at 0.5, 1, 1.5, 2, 3 and 4 W. The laser was used in two operating modes: pulsed 
      (pulse 0.5 s) and continuous mode with exposure time of 10 s. Under the 
      conditions of this experiment, temperature rises of between 1.5 and 19.1 degrees 
      C at the external root surface and 1.5 and 12 degrees C inside the root canal and 
      horizontally across the sectioned root surface were recorded. The results 
      obtained with IR camera showed a higher temperature on the external root surface 
      than the digital thermometer during and after lasing the root canal. Scanning 
      electron microscope (SEM) analysis revealed that even low laser energy 
      significantly damaged the external root cementum surfaces.
