Paper Abstract

The aim of this investigation is to define optimal parameters of KTP laser irradiation during caries removal. 12 decayed human teeth, recently extracted were used. Their rot canals were prepared for insertion of a thermocouple probe into the pulp chamber. The demineralized tissues have been colored by Acid Red 52 before proceeding to different conditions of irradiation. Pulpal temperature increases were found under the following parameters with 15 seconds continuous lasing: 400mw, 0.10 m sec pulse width, PRR <EQ 60 Hz or 400 mw, 0.12 m sec pulse width, PRR <EQ 50 Hz for efficient caries removal. A resting time average of 70 s was necessary to allow pulp temperature to get back to its baseline.
