Temperature variations in pulp chamber: an in vitro comparison between ultrasonic and rotating instruments in tooth preparation.

CONCLUSIONS: Within limitations of this study, temperature increasing of ultrasonic instruments shows a statistical difference related to rotary ones. But, as literature shows, the ultrasonic advantages are margin precision, preservation of soft tissues and reduction of operating times. Furthermore, in relation with results of this study, they could be considered safe for pulp vitality because the increase in pulpal temperature is similar to traditional instruments and it doesn't exceed the critical level of 5,5°C.
