YEVENES-BRIONES, Humberto et al. Chilean dentists' knowledge of hearing loss generated by occupational noise exposure. rev.fac.med. [online]. 2021, vol.69, n.2, e205. Epub 23-Jul-2021. ISSN 0120-0011. https://doi.org/10.15446/revfacmed.v69n2.77902.
Introduction:
Dentists are a population at high risk of hearing loss due to their constant exposure to instruments that can generate noise of up to 100 dB during their practice.
Objective:
To determine the level of knowledge of dentists working in Chile regarding hearing loss caused by exposure to noise generated by dental instruments.
Materials and methods:
A cross-sectional study was conducted in 114 dentists, who completed a virtual survey of 22 questions regarding the perception and level of knowledge about hearing loss due to exposure to loud noises and about national regulations on occupational noise exposure. Differences between perception and knowledge levels were evaluated taking into account the years of professional practice and the average weekly workload in dental treatment rooms. Descriptive and inferential statistics (Chi-squared test) were used for data analysis.
Results:
Most participants were Chilean (99.1%); 58.8% were women, and 72.8% had less than 10 years of professional experience. In addition, 97.4% were unaware of national regulations on occupational noise exposure and 50% of the sample reported having experienced hearing loss; of these, 57.9% (n = 32) associated it with their practice.
Conclusions:
A very low percentage of participants knew that there are regulations regarding occupational noise exposure. For this reason, it is important that, both during their training and their professional practice, dentists in Chile have greater access to information about these regulations and hearing protection measures.
