What the count covers

269 NPPES records list orthodontics and dentofacial orthopedics dentistry (1223X0400X) as their primary taxonomy with a practice address in Maryland: 4.4 per 100,000 residents against 4 nationally (50 states and D.C.). Baltimore has 26 of them (10%).

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.
