The beak was probably overgrown which is why it broke off. It should grow back. Keep a piece of cuttlebone in the enclosure - chewing on if will help to keep the beak in shape and prevent further breakages. Cuttlebone also means your tort can help himself to calcium when it wants it.
It is possible that not all the beak came loose. Diet and care may also be a cause, but @Yvonne G would know for certain. Message her if she doesn’t come back.
I have no idea what the black powder on the shell is. I can’t see it on the photos. I doubt it is mold of any kind in the very dry enclosure you have.
