OdneClean: Evaluation of bacterial biofilm, smear layer, and debris removal efficacy of a hydro-dynamic cavitation system with physiological saline using a new ex vivo model: a CLSM and SEM study
BMC Oral Health
OdneClean is a cutting-edge hydro-dynamic cavitation-based irrigation system using water as its main debridement medium. This study compares the effectiveness of OdneClean, without using any additional chemicals, with syringe needle irrigation (SNI) and passive ultrasonic irrigation (PUI) in cleaning root canals. Using dentin blocks from human teeth with bacterial biofilms grown on them, OdneClean with saline outperformed both SNI and PUI with saline, effectively removing biofilm and debris. Notably, OdneClean with saline was as effective as SNI and PUI with 3% NaOCl and matched the debris removal efficiency of 5% NaOCl followed by 17% EDTA. EDTA was found to still be required for chemical dissolution of the smear layer. In summary, OdneClean offers a powerful alternative to conventional irrigation devices, significantly reducing the need for chemicals during root canal treatment.
