The heat generated on the external root surface of human premolar teeth during post space preparation was measured in vitro. The rise in temperature was recorded at a point 6 mm from the apex of the tooth using a thermocouple attached to a chart recorder. The temperature rise was greatest when the removal of gutta-percha was combined with post channel preparation. Temperature rises of up to 31 degrees C were recorded. Instruments that only removed gutta-percha did not generate the same amount… CONTINUE READING
