What the count covers

37 NPPES records list orthodontics and dentofacial orthopedics dentistry (1223X0400X) as their primary taxonomy with a practice address in District of Columbia: 5.4 per 100,000 residents against 4 nationally (50 states and D.C.). Washington has 37 of them (100%).

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.
