Influence of luting agents on time required for cast post removal by ultrasound: an in vitro study.

Objective: This in vitro study evaluated the influence of luting agents on ultrasonic vibration time for intraradicular cast post removal.

Material And Methods: After endodontic treatment, 30 roots of extracted human canines were embedded in resin cylinders. The post-holes were prepared at 10 mm depth and their impressions were taken using autopolymerizing acrylic resin.
