Dental drills and hearing

["Francis F. Chen" <ffchen@xxxxxxxxxxx>]

Dear Auditory List:

        I am a physicist who has suffered a hearing loss three times in a 
row after visits to my dentist.  I have measured this myself in detail.  I 
suspect the cause may be ultrasonic vibrations created by the turbo drill, 
or the anesthetic that was used.  I have found references to hearing loss 
of dentists, but not of patients.  Does anyone know of such references?
