Use of hearing protection devices in the clinical dental setting: A pilot study

Noise in the clinical dental setting has been shown to exceed safe levels, and the risk to dental professionals, including occupational noise-induced hearing loss, is well-established. This pilot study investigated dentists' perceptions and experiences of the use of custom-made earplugs as a means of attending to the risk in the clinical dental setting. Dentists were recruited using convenience and purposive sampling and provided with custom-made attenuated earplugs, which were worn for a period of 12 weeks of usual clinical dental practice. Questionnaires were completed periodically. Data were analyzed statistically and thematically. There was a total of eight participants. Participants recognized the risk of hearing loss and supported the promotion and inclusion of hearing protection as a part of personal protective equipment. Participants noted an improved focus due to a reduction in noise perception. Disadvantages included discomfort and communication challenges. This pilot study assessed the process for, and feasibility of, conducting a larger-scale study and will contribute to the reliability and validity of such, which is recommended.
