Results of the audiometric tests for air conduction for the right and left ear. The comparison of the results of the audiometric tests for air conduction for the dentists (n = 53) and the control group (n = 55) showed that the hearing impairment was only slightly more pronounced in the dentists than in the control subjects, at frequencies of 3 kHz and 4 kHz the differences were marginally statistically significant for the right (a) as well as the left ear (b); asterisk: P < 0.05.
