Reading this score

computed

At 21.7% of weighted task load, Dental Hygienists sits at the 40th percentile, below the point where a job's centre of gravity has moved. 61.2% of what this role does is untouched, meaning current systems cannot produce that work at all, whatever the commercial incentive.

What holds the line here is accountability. Across this occupation's 16 tasks it averages 2.34 out of 3, the highest of the five friction dimensions. In plain terms, someone licensed has to sign the work. Capability and permission are different things. Where a statute or a professional body requires a named, liable human to approve the output, the work can be drafted by a machine and still require the person.

The most exposed thing this job does is Maintain patient recall system, at 83.3%. The least is Make impressions for study casts, at 0.0%. A gap of 83.3% between two parts of the same job is the reason this index publishes at task level. An occupation-wide number would have hidden both.

Within healthcare practitioner and technical occupations, this one is more exposed than most. The median across the 89 roles in the group is 18.4%, and only 24 of them score higher than this. Occupational families are not uniform, and the spread inside them is often wider than the gap between them.

What would move this score. Of 16 tasks, 5 are currently banded exposed, 1 assisted and 10 untouched. For that distribution to shift materially would take robotics cheap and reliable enough to deploy at scale, not a better language model. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.

Where the score comes from

The four closest scores in the same occupational family, then the four closest anywhere in the index.

Read this carefully. Exposure is not displacement. A high score means current AI systems can produce this work, not that anyone will stop paying a person to do it. Adoption depends on economics, regulation and inertia that this index deliberately does not model. How the score is built.

What this means in practice

Most of this work is not reachable by current systems, so the immediate pressure is on the administrative edges of the role rather than its core: the scheduling, the reporting, the written records. That is where time is recovered.
