What the count covers

465 NPPES records list general practice dentistry (1223G0001X) as their primary taxonomy with a practice address in Montana: 41 per 100,000 residents against 37 nationally (50 states and D.C.). Billings has 86 of them (18%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
