SP-17 The Impact of Irrigation Strategy on Endodontic Outcome
CE Hours: 1.0
Description: Root canal irrigation plays a key role in the removal the pulp tissue, contaminants, debris and microorganisms from the root canal system. Different adjunctive agitation techniques have been developed to help irrigating solutions penetrate the complexities of a root canal system. Passive ultrasonic irrigation, multisonic agitation (Gentlewave™), sonic activation (EndoActivator™), and apical negative pressure irrigation systems (EndoVac™) have been reported to be superior to conventional positive pressure needle irrigation in regards to smear layer removal, antimicrobial effect, and decreased post-operative pain. However, is there enough evidence to show these adjunctive agitation techniques actually improve the success of root canal treatment? Based on a review of the current literature and personal clinical experience, the potential advantages of the commonly used systems will be explored
- List commonly used adjunctive agitation irrigation techniques.
- Evaluate the current best available evidence to support the use of specific adjunctive agitation irrigation techniques.
- Choose the most appropriate adjunctive agitation techniques for root canal treatment.
