Audiograms were obtained just before and immediately after scaling. Temporary shifts in hearing threshold (TTS) of 10-20 dB, mostly at 7-8 kHz, persisting for up to 30 min, were recorded in eight of the individuals. Three patients reported high-pitched tinnitus lasting for 20-30 min after ultrasonic scaling. When audiograms were obtained 3-5 weeks later in the same 20 individuals before and immediately after they had kept their mouths open for 5 min, but with no scaling performed, TTS was recorded in three of the individuals. TTS after opening only was less pronounced than TTS after ultrasonic scaling, both with regard to severity and duration. Accepted for publication: August 6, 1975. |
