There have been many studies over many years on dentifrices and every dental school in the country teaches their students that using toothpaste with proper tooth brushing technique is an important component of good dental health.

I've seen this debate elsewhere more than once and nobody ever comes up with the beef: links to the definitive, conclusive studies on the subject that you suggest exist. I'd be surprised if it were any different this time.
