Brief Summary: StudyProtocol Title An in vivo comparison of the debridement efficacy of needle irrigation and ultrasonic root canal irrigation techniques

1 The purpose of this study is to compare the Vista ultrasonic bypass system and conventional needle irrigation to effectively clean the bottom third of the root canal during root canal therapy
2 Participants will be recruited from the general patient pool of the OHSU School of Dentistry Patients will have to qualify for the study by meeting the following criteria age between 18 and 75 years old ASA status I or II are currently planning treatment for the extraction of teeth and the patient understands and signs the consent form The principal investigator will conduct an interview with the patient and the student-provider and obtain informed consent from the patient
3 The teeth to be extracted will be numbed with local anesthetic The teeth will be isolated with a rubber dam and disinfected The pulp chamber will be accessed using normal dental equipment and the root canal will be cleaned and shaped using either the ultrasonic irrigation technique or needle irrigation This is the first step of standard root canal therapy The tooth will then be extracted and the principal investigator will retain extracted teeth to perform further examination to see how thoroughly the root canals were cleaned The teeth will be discarded after study
4 Not applicable
5 The investigational device Vista ultrasonic bypass system consists of a 30 gauge slot needle which attaches to an ultrasonic unit Satalec P5 Irrigants will be delivered to the apical 13 of the root canal through the needle at the same time the needle is being activated ultrasonically Irrigant delivery will be controlled by a standard syringe pump Conventional needle irrigation will be delivered using a 27guage slot needle placed into the root canal Irrigants will be expressed with positive pressure at a location in the canal short of the needle binding
6 Once the first step of root canal therapy has been completed the tooth will be extracted decalcified and tissue specimens will be taken from the bottom 3 mm These sections will be evaluated under magnification and remaining debris in the root canal will be quantified using the NIH Image software The data will be statistically analyzed to determine and differences between the two irrigation techniques
