Doctors believe Artificial Intelligence is now saving lives, after a major advancement in breast cancer screenings. A.I. is detecting early signs of the disease, in some cases years before doctors would find the cancer on a traditional scan. Gum disease (periodontitis) affects more than 47% of Americans -- or nearly 65 million people -- including former Major League Baseball player Alex Rodriguez, who recently announced he has the condition. As artificial intelligence continues to expand into dental and medical uses, dentists are relying on the technology to quickly and accurately detect and prevent periodontitis, decay, bone loss and other gum health issues. Now, VideaHealth, a medical technology company in Boston, has created a dental AI platform that is available to 90% of dental practices in the U.S., the company said.
