| 109 | COMBINED USE OF ULTRASOUND WITH NICKEL TITANIUM ENDODONTIC FILE IN ENDODONTIC PROCEDURE | US14775444 | 2014-03-14 | US20160022377A1 | 2016-01-28 | Carlos Alberto Spironelli Ramos; Richard D. Tuttle |
| Methods and related systems for cleaning a root canal of a tooth employing a super-elastic NiTi endodontic file while applying ultrasonic energy during the cleaning procedure. Such a method may include inserting an endodontic file into a root canal of a tooth in which the file includes a working portion comprising a super-elastic NiTi alloy.The root canal is cleaned by moving the working portion of the file within the root canal so that the working portion of the file cuts or abrades tissue within the root canal. Ultrasonic energy is applied to the file, tooth, or both in order to assist in breaking up and removing necrotic tissue in the root canal during cleaning. The ultrasonic energy is applied in a manner that does not result in breakage of the file for a period of at least 3 minutes. In an embodiment, a length of the exposed portion of the file is maintained at 22 mm or more to delay file breakage. | ||||||
