A comparison of Er, Cr: YSGG laser with ultrasonic preparation on the seal of retrograde cavities.
BACKGROUND AND AIM The aim of this in vitro study was to compare Er, Cr: YSGG laser with ultrasonic preparation on the seal of retrograde cavities. MATERIALS AND METHODS Twenty-eight maxillary anterior teeth were used in this study. After removing the crowns, the canals were prepared with the step-back technique and filled with guttapercha. Three millimeters below the apex; each root was cut ...
