What the count covers

184 NPPES records list periodontics (1223P0300X) as their primary taxonomy with a practice address in Washington: 2.4 per 100,000 residents against 2 nationally (50 states and D.C.). Seattle has 38 of them (21%).

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.
