- Collected: 5 practices with a SmilesAtlas profile (dentists registered under NPPES taxonomy code 1223X0400X, Orthodontics and Dentofacial Orthopedics), joined to the NPPES registry, the Dental Board of California license roster, their Google listing and their own website.

- Published: 19 counts for this page; practice-level facts stay on each practice's profile and on the official sources.
- Computed: 4 derived shares, each with its formula and arithmetic in the dataset.
- Method: a practice is verified when all four fields pass: a dentist at the practice matched by license number and listed as active by the board, an NPI, a practice ZIP matching its Google listing, and one fact the practice publishes itself. Verified means the records match; it is not a rating. How we verify.
