I'm surprised this thread hasn't attracted more attention by now.
I just read the article directly from the November issue of Caries Research, and if this mouth rinse proves to be as effective in long-term clinical trials as it was shown to be in the 4-day pilot study described by the authors, the dental profession may be in for a squeeze. Obviously the sky is not about to fall, especially not for currently established and practicing dentists, but what about for those of us just entering school and in the future?
The non-compliance argument sounds like a weak one to me, especially considering that this study's findings show a significant reduction of S. mutans, lactic acid and enamel demineralization after just one rinse performed at the beginning of the 4-day trial period.
Also keep in mind that, although the results obtained from this study are stellar, the technology being utilized here is still relatively new. Criticizing minor kinks in this rinse's efficacy or potential side effects at this point would be like criticizing the Wright brothers for failing to equip the seats in their airplane with TVs and satellite radio.
This is all just food for thought. What do others think about how this could affect the dental profession?
