Dentists and dental hygienists experience elevated rates of musculoskeletal disorders, such as carpal tunnel syndrome and tendonitis, primarily due to the high pinch force required for dental scaling. There is evidence that a lighter and larger diameter tool can significantly reduce the pinch force. This randomized controlled study will determine if dentists or dental hygienists who use such a tool report less hand and arm pain compared to those who continue to use the conventional tool design.
