I am completely against the use of high speed handpieces by DAII's in patients mouths. We train dental students for four years to do this irreversible treatment and no amount of training for a dental assistant will qualify them to be as competent to do these proceedures as a dentist. I feel they should go to Dental School to be trained properly and pass the Board Exam before doing so. If this is put into law the Commonwealths' citizens will be put at risk. I realise access to care is a problem but to have assitants doing this type of treatment is unfair to the public and should be prohibited.
