title: Gaining access to calcified canals.
abstract: Gaining entrance to calcified canals can be very difficult and at times impossible. With the aid of the EDTA-Urea preparation (RC-Prep, Premier Dental Products, Norristown, Pa.) and the surgical length contra-angle burs, the task can be facilitated. The use of the multipurpose probe reduces the problem of perforation. We may now be able to gain access and treat a greater number of calcified canals.
