So basically Minnesota created a group of people to try to figure out what this new practitioner would be...which means shut the hygienists up for a little while.
I personally think this is b.s. Do one of two things - get rid of dentists and let the all knowing hygienists do what they want or two - make dental school quicker to finish and open up 100 more schools. Either way, allowing a "Practitioner" to do irreversible procedures is doing one of the two above options.
But, like I said, this is most likely just something to shut the hygienists up until 2011. Come 2011, we will find out that all their research has proven what we already know. If you want to be a hygienist, go to hygiene school. If you want to be a dentist, there are 50+ schools you can apply to.
