The aim of this in vitro study was to compare the sealing effectiveness of the Erbium:YAG laser to the sealing effectiveness of an ultrasonic device in the preparation of similar retrograde cavities using different retrograde filling materials. After root-canal instrumentation and filling, apices of 60 single-rooted teeth were resected. Retrograde class I cavities 3 mm deep were prepared using an ultrasonic device (group A) and Er:YAG laser (group B). An ultrasonic unit was used with CT-5… CONTINUE READING
