In the present study, our objective was to quantify the daily duration of vibration exposure from ultrasonic scaling in dental hygienists and to compare different methods of self-estimates to time-recorded measurements. The exposure time was self-estimated by use of diary and interview methods in 10 subjects. We found that the measured total daily exposure time was limited, only on average 12min, with a great variation, however, between and within the subjects. Self-assessed duration of exposure was overestimated, on average three times higher with a diary and even more at an interview (8 times). In conclusion, the objectively measured exposure time was short and clearly overestimated in self-reports.
在本研究中，我们的目的是量化牙科保健员超声洁牙时每日的振动暴露时长，并比较不同的自我估计方法与时间记录测量结果。通过日记和访谈方法对10名受试者的暴露时间进行了自我估计。我们发现，测量的每日总暴露时间有限，平均仅为12分钟，然而，受试者之间和受试者内部存在很大差异。自我评估的暴露时长被高估，使用日记时平均高估三倍，访谈时甚至更高（高估八倍）。总之，客观测量的暴露时间较短，且在自我报告中明显被高估。
