Abstract

The root-end resection is considered critical endodontic surgical procedure. Three millimeters of the root tip is resected and root-end cavity with parallel walls and comparable depth is cut to receive a root-end filling. The literature discussed dentinal cracks after root canal instrumentation and/or root dentine cutting. The aim of the present study was to assess cracks at root ends after resection with conventional versus ultrasonic techniques. Material and Methodology: Thirty-two extracted human lower premolar teeth with single root were used. Their root canals were prepared and received gutta-percha. Sixteen roots Group 1 were resected using tungsten carbide fissure burs, while other sixteen teeth Group 2 were resected with ultrasonic tip, then all teeth had root end preparation with the ultrasonic coated retro trip. Both amount and categories of cracks on the resected surfaces were evaluated utilizing a dental operating microscope prior and following cavity preparation. Result: Cracking was statistically significant different among the two groups after resections or after cavity preparation.
