What the count covers

929 NPPES records list periodontics (1223P0300X) as their primary taxonomy with a practice address in California: 2.4 per 100,000 residents against 2 nationally (50 states and D.C.). Los Angeles has 73 of them (8%).

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.
