| Abstract |
The objective of this study was to determine whether odontology students and dental surgeons were at risk of hearing loss related to the noise from high-speed motors used in this profession. The study involved 80 students and 40 dentists exposed to noise, together with a control group of 20 dentists unexposed to noise. All participants were subjected to audiometric examinations for frequencies ranging from 250Hz to 16kHz; those handing mercury were further subjected to a urinary mercury determination. Hearing loss was observed among 5% of the students and 70% of the dentists. Dentists exposed to noise showed a more pronounced hearing loss and higher levels of urinary mercury. |
