[Temperature determination of root surfaces in manual and mechanical preparation of root canals].
In in vitro studies it was determined which temperatures develop on the root surface using different root canal preparation techniques. 62 teeth were filed manually, by conventional mechanic technique and by ultrasonic driven instruments. Practicing manual and mechanic filing critical temperatures for the cell structures of the desmodont did not develop. Ultrasonic and ultrasonic--like instruments, however, develop high temperatures on the root surface so that the cooling effect of the irrigation liquid after each instrumentation is not sufficient and a continuous irrigation during filing is indicated.
