Evaluation of the efficiency of cleaning dental plaque on titanium using a cavitating jet

open access: yesJournal of Biomechanical Science and Engineering, 2014
Dental plaque, which adheres to the surfaces of dental implants and remains in the gingival crevices, can cause peri-implantitis, which is similar to periodontal disease; consequently, cleaning the dental plaque from these surfaces is very important.

Bacterial Sterilization Using Cavitating Jet

open access: yesJournal of Fluid Science and Technology, 2007
In this paper, a new sterilization method using cavitating flow is presented. Water with bacteria was pressurized up to 105 MPa and flushed out through two very small nozzles 0.1-0.31 mm in diameter, where a cavitating jet was generated containing ...

Enhancement of an aggressive intensity of a cavitating jet by water flow holes near nozzle outlet

open access: yesNihon Kikai Gakkai ronbunshu, 2019
The cavitation cloud generated by submerged high-speed water jet has periodicity. The periodicity is provided by alternately repeating the bubbles generation and shedding process and cavitation nucleus filling process.
