目的 本研究的目的是检查牙科人员的听力阈值。第二个目的是评估牙科人员接触的牙科设备的声音水平。方法 244 名牙医、牙科技师、牙科助理和牙科学生参与。六十二人作为对照组参加。将测试组的听力阈值与对照组进行比较。所有参与者均来自约旦大学医院。参与者除了听力测试外还完成了一份调查问卷。他们的评估包括耳镜检查、鼓室导抗测试和纯音听力测试。采用三因素方差分析和t检验来评估各组之间以及两耳之间听力阈值的统计差异。采用皮尔逊相关性检验评估年龄、经历和暴露时间对测试组双耳听力损失程度的影响。结果 作者报告了对照组和其他组之间听力阈值之间存在统计学上的显着差异。牙科助理在 1000、2000、4000 和 8000 Hz 频率下的左耳听力阈值明显低于右耳。作者还报告了牙医助理的听力损伤程度与每天接触牙科职业噪音的时间之间存在显着关系，其次是年龄。结论 牙科专业人员的听力障碍程度高于对照组，尤其是牙科助理和技术人员。作者为牙科专业人员，特别是牙科助理和技术人员推荐了筛查指南和调整听力保护方法。
Objectives The purpose of the study was to examine hearing thresholds among dental personnel. The secondary aim was to evaluate sound levels among dental equipment that dental personnel are exposed to. Methods Two hundred forty-four dentists, dental technicians, dental assistants, and dental students participated. Sixty-two participated as a control group. Audiological thresholds for the test groups were compared to the control group. All participants were from Jordan University Hospital. Participants completed a questionnaire in addition to their audiometric testing. Otoscopy, tympanometry, and pure tone audiometry were included in their assessment. Three-factor ANOVA and t tests were utilized to assess the statistical differences of hearing thresholds among the groups and between the two ears. Pearson correlation test was used to assess the effect of age, experience, and duration of exposure on the degree of hearing loss in the test groups for both ears. Results The authors reported statistically significant differences among hearing thresholds between the control group and others. Left hearing thresholds were noted to be significantly poorer in the left versus right ear at 1000, 2000, 4000, and 8000 Hz in dental assistants. The authors also reported a significant relationship between the degree of hearing impairment among dental assistants and the daily duration of exposure to dental occupational noise, followed by age. Conclusion Hearing impairment was higher among dental professionals than the control group and especially among dental assistants and technicians. The authors recommended screening guidelines and adapting hearing protection methods for dental professionals and particularly for dental assistants and technicians.
