I saw this article in today's Toronto Star about cavity detection without x-rays. It initially sounded similar to Diagnodent, which has issues detecting caries (cavities) in between teeth. I'm still waiting for more details before I form an opinion. Here's the teaser quote:
Once a cavity has formed and exposed itself on the surface, it's too late – it has to be cleaned out and filled.
Abrams says the industry needs to take a more preventative approach, and this is where Quantum Dental enters the scene. The company's research team, based out of the University of Toronto, has developed a prototype of a laser device that uses heat and light waves to detect tiny, below-surface lesions in teeth without exposing a patient to potentially harmful radiation.
A commercial prototype is scheduled to be launched next summer and, after a year of clinical testing, the company hopes to begin selling the device in the fall of 2009.
Dentists will still need x-rays to look at jawbone structure, but Abrams believes Quantum's device has the potential to be a fixture in every dentist's office. The absence of radiation means it can be a standard offering whenever someone gets in the dentist's chair, improving the chance of catching early-stage tooth decay before it becomes a bigger problem.
