Ultrasonic cleaning of root canals - Endodontic therapy through microstreaming and cavitation (07498)

Project nummer: 07498

Omschrijving van het onderzoek

In the Netherlands 2000 root canal treatments are performed every day. The goal of a root canal treatment is to remove inflamed and infected pulp tissue, dentine debris and microorganisms from the root canal system of a tooth. Key to a successful therapy is a complete removal of the microorganisms from the root canal system. In conventional treatment using syringe irrigation only a moderate reduction of the amount of microorganisms can be achieved; the success rate of a root canal treatment is therefore very low, 40% of them will sooner or later be associated with apical periodontitis, an inflammation at the root tip. Ultrasonic irrigation through piezoelectric activation of endodontic files could result in a much higher success rate, as this comes close to a bacteria-free situation. Acoustic streaming and possibly cavitation contribute to the cleaning efficacy. Why and how this works remains unclear until today. Here we propose to investigate the underlying physical mechanisms of ultrasonic endodontic treatment through a combination of in vitro laboratory and ex-vivo clinical experiments.
