scanO

No, and we do not use it as one. It reads photographs of the tooth surfaces you can see in a mirror. It cannot reliably check between your teeth, and it cannot see below your gum line, inside a tooth, or under a tooth filling or dental crown. That is a large share of what an examination is looking for.

Published research on AI reading decay in photographs reports F1-scores from 42.8% to 95.4% depending on the camera used, and none of those studies tested scanO. F1-scores and "accuracy" figures measure different things, so they cannot be compared directly. Be careful with any single accuracy figure quoted for a product in this category unless a peer-reviewed study sits behind it.

Yes. scanO works from ordinary photographs, so there is no radiation in the scan itself. That is also its main limitation, because decay between teeth is assessed with bitewing X-rays where your dentist judges them necessary, and those do involve a small dose.

No. If it flags something, treat that as a prompt to get examined. If it says nothing, do not take that as the all-clear. Either way, the value is in what you do next.
