Evidence stage
ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
Working within scope
Knowing which decisions belong to the dentist and which the hygienist may make.
Still human-led✓ Evidence-backed
Where this applies
One US state. Section 1908 defines the practice of dental hygiene to include preventive and therapeutic services and states that it does not include diagnosis and comprehensive treatment planning, placing permanent restorations, or surgery; local anaesthesia is covered by section 1909. It governs who does what between hygienists and dentists and does not mention software.
What this means
Where the law keeps diagnosis with the dentist, an AI finding on an X-ray lands with the dentist too.
What it does not yet show
One state's scope rule; others differ, and it does not address AI.
What you can check
Open California Business and Professions Code section 1908 and find "Diagnosis and comprehensive treatment planning".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
