Duration of the procedure of extraction of the molded pin tabs root canal by means of ultrasound in the clinic
Abstract
We studied the duration of ultrasound exposure with the least risk of periodontal damage when removing well cast root inlay made taking into account the anatomical features of root canals. 5 Total successfully completed cases was analyzed. We used standard elongated ultrasonic nozzle to remove dental plaque at the maximum ultrasonic power with constant copious water cooled in the cervical region, for 15 seconds on each side, the results obtained without complications. Coppa crown remover used when a mobility features cast root inlay. After a 10-minute periods of use of ultrasound were 2-minute rest periods. It took 2 to 6 visits without anesthesia for temperature control by the patient. The number of visits depends directly on the number of channels used for fixing pin. The number of visits is inversely related to the statute of limitations, and operating time cast root inlay.
