Abstract
A nickel-titanium file root canal preparation instrument, including a nickel-titanium preparation system and a water flushing system. The nickel-titanium preparation system includes a nickel-titanium file, a handheld device head, a handheld device body, an electric motor, and a power controller; the water flushing system includes a conduit, a conduit fixing device, a liquid pump, and a liquid pump controller. The existing theory and study regarding root canal preparation has misled people about the root canal preparation method, and this leads to the result that the existing nickel-titanium root canal preparation is implemented in a dry-drilling manner. By providing a water flow to perform flushing during the root canal preparation of the nickel-titanium file root canal preparation instrument, the service life of the nickel-titanium file is prolonged.
