title: Evaluation of root canal débridement by the endosonic ultrasonic synergistic system.
abstract: The endosonic ultrasonic synergistic system was compared to conventional hand-filing and irrigating techniques for its ability to débride the root canal system. Extracted human teeth were endodontically prepared by conventional and ultrasonic techniques. The roots were cross sectioned and evaluated microscopically at the 1, 3, and 5 mm. levels from the apex for cleanliness. The endosonically prepared canals were significantly cleaner at all levels.
