Objectives/Aims:

The aim of this study is to evaluate if the duration of the consultation has influence on the intensity of noise in the dental clinic environment.

Materials and Methods:

The measurement was performed using the decibelmetre IDETEC 300. It was turned on among 10 dental equipment at basal time (BT) and in the first, second and third hours of activity by 10 times with 1-week interval.

Results:

The average noise was 67.39±1.11 dB for BT and 82.38±3.85, 80.99±4.78, and 70.06±6.95 dB for hours 1 to 3, respectively, representing a significant difference (ANOVA, F(3.36)=29.28, P<0.0001).

Conclusion:

In the first and second hours of clinical care there was more noise intensity in the work environment compared to BT and to the third time. Furthermore, the noise peaks became closer to the limit of 85 dB, which can threaten hearing loss with repeated exposure throughout a dentist’s career.

Discussion:

The findings presented here show how much the dental surgeon is exposed to the level of noise since his time of study.

牙科教学诊所的噪声强度评估

目标/目的：

本研究的目的是评估咨询的持续时间是否会影响牙科诊所环境中的噪音强度。

材料和方法：

使用分贝计 IDETEC 300 进行测量。在基础时间 (BT) 以及活动的第一、第二和第三个小时，以 1 周的间隔在 10 台牙科设备中打开 10 次。

结果：

BT的平均噪声为67.39±1.11 dB，第1至3小时的平均噪声分别为82.38±3.85、80.99±4.78和70.06±6.95 dB，差异显着（ANOVA，F（3.36）=29.28，P <0.0001） .

结论：

与 BT 和第三次相比，在临床护理的第一小时和第二小时，工作环境中的噪音强度更大。此外，噪声峰值变得更接近 85 dB 的极限，这可能会在牙医的整个职业生涯中反复暴露于听力损失中。

讨论：

此处提供的研究结果显示了牙科医生自学习以来暴露于噪音水平的程度。
