Abstract:

Background Since the introduction of the high-speed handpiece in 1957, dentists have been concerned about the risk of hearing loss caused by chronic exposure to the high frequencies of the air-turbine motor. Although most studies have reported handpiece noise levels to be within OSHA standards, the literature regarding handpiece-induced hearing loss among dental providers remains equivocal, warranting continued concern. Moreover, handpiece noise may hinder office communication and increase patient anxiety. Purpose To determine if three noise-reducing techniques utilized in larger scale, nondental turbines can be applied to dental hand pieces to reduce noise emission without compromising performance.
