What these measures tell you

Units of Dental Activity (UDA) and Units of Orthodontic Activity (UOA) measure different contract activity. Monthly delivered units and annual contract targets have different time windows. They are not appointments available to book.

Child patient counts use a 12-month window; adult patient counts use a 24-month window. They are not monthly appointment totals or evidence that a practice is accepting new patients. Orthodontic starts and completions count different cohorts, so their ratio is not a treatment-success rate.
