Introduction:
The purpose of this study was to evaluate noise levels in dental offices and to estimate the risk and prevalence of tinnitus and noise-induced hearing loss (NIHL) in practicing dentists.
Materials And Methods:
First, measures were collected of sound pressure levels produced by dental handpieces and dental suction in the University of Oklahoma Health Sciences Center (OUHSC) College of Dentistry. Second, a survey was distributed to members of the Oklahoma Dental Association (ODA).
Results:
Measurements made in the dental operatory revealed dangerous levels when high-volume suction was in use alone and in conjunction with a dental handpiece. Questionnaire results suggested that practicing dentists report sensorineural hearing loss at a rate broadly in line with national averages. However, dentists reported a higher prevalence of tinnitus symptoms than would be expected based on sample demographics.
Conclusion:
Results from sound level measurements and questionnaire responses indicate that dentists are a population that could be placing their hearing health at risk in a typical daily work environment.
