What digital SLR camera is good for dental photography?

It has little to do with the camera At present, there are several SLR cameras that can do it. Nikon Canon Sony, entry-level will do. But the lens needs to be special, that is, it needs a macro head of 100 microns, that is, 100 or 105, and a macro of 55 is also acceptable. Buy a macro of 1: 1, that is to say, you can shoot the tooth size of 1: 1. Another problem is lighting. Ordinary flash is not good. You need a ring flash. It's not cheap. Of course, if you use professional dental spotlights, it may be ok, but you are not familiar with it and it is not easy to draw conclusions.
