CRA Conclusions Back to Page Contents
All 6 low speed handpieces tested had designs that allowed intraoral polishing at sufficiently low speeds necessary for patient comfort & designs that provided clinician comfort. Smoothest operating handpiece was RDH with Prophy Right Angle followed closely by RDH for Disposable Angles, but both require more time consuming maintenance regimen. Best overall for ease of operation & maintenance was PHP 100 & 130, followed closely by Prophy Star. Purchase choice can be made by features desired by clinician, because all handpieces performed intraoral polishing well.
