The effect of high-speed dental turbines on dentists' hearing was investigated. The two types of dental turbines used most commonly in the Tel Aviv area and their average time of daily use were established by means of questionnaires. The noise pressure level of these turbines at a distance of 30.0 cm was measured. Twenty subjects were exposed to the turbine noise for a period equal to the average time of the drill's daily use. The noise pressure levels of the turbines were found to be nonhazardous by the accepted damage-risk criteria. The temporary threshold shifts of the subjects exposed were nil or insignificant. It was concluded that the risk of damage to the dentist's hearing due to dental turbine noise in the normal course of a working day is slight.
研究了高速牙科涡轮机对牙医听力的影响。通过问卷调查确定了特拉维夫地区最常用的两种牙科涡轮机及其每日平均使用时间。测量了这些涡轮机在30.0厘米距离处的噪声压力水平。20名受试者暴露于涡轮机噪声中的时间与钻头的每日平均使用时间相等。根据公认的损害风险标准，发现涡轮机的噪声压力水平无危害。暴露受试者的临时阈移为零或不显著。得出结论，在正常工作日，牙科涡轮机噪声对牙医听力造成损害的风险很小。
