Dentist

The regulator's clearance letter of 10 May 2022 with the device's indications for use and 510(k) summary, read in the full PDF. The software is cleared to aid in detecting and outlining caries on bitewing radiographs, providing additional information for the dentist; it is not intended as a replacement for a complete dentist's review or clinical judgement, should be used only by trained dentists, assists only in detection and not interpretation or diagnosis, and should not be the sole decision-making tool for diagnosis or treatment; final clinical determination is the treating clinician's. The summary reports the manufacturer's own testing: standalone sensitivity 72.0% and specificity 98.1% on 352 images; in a reader study with 13 US-licensed dentists, sensitivity rose from 57.9% unaided to 76.2% aided while specificity fell from 99.3% to 98.4%. It lists limits including decay hidden by restorations, gross decay and endodontic access mistaken for caries. It establishes what one tool may be sold to do and its manufacturer's reported performance; it is not a measure of use in practice, and a capability record moves nothing on this page.

A demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.

The Act as published on Singapore Statutes Online, in force since 15 October 1999, read in the current version (2022 revised edition). Section 2 defines the practice of dentistry to include any procedure on and treatment of the teeth, jaws or associated structures; radiographic work in connection with them; administering an anaesthetic for such procedures; and procedures for dentures and dental appliances. Section 29(1): a person must not practise dentistry in Singapore unless the person is a registered dentist and has in force a practising certificate; registered oral health therapists may practise within their prescribed scope, and contravention is an offence. Section 21(4) makes it a condition of registration for several categories of oral health therapist that they practise only under the supervision of a registered dentist, with exceptions including the public service. It establishes who may lawfully do this work in Singapore; it says nothing about the tools a dentist uses or how many dentists there are.

Failure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.

If you are starting in dentistry, expect AI to be part of reading X-rays and keeping records from the beginning — cleared tools already mark suspected decay for you. The law and those tools' own conditions keep diagnosis, treatment and responsibility with you, so the skills that matter most are the ones they do not replace: clinical judgement across all the information, and precise hands. Learn where the tools miss — the clearance lists some — as carefully as where they help.

Your judgement is what the cleared tools are built around: they are allowed to point, not to decide. The dentists these changes favour are the ones who know when to overrule the software and who can supervise a team that uses it, because the law makes you answerable either way.

Stay and strengthen

Stay in general practice, and use the tools well

Diagnosis and treatment stay with the registered dentist by law, and cleared AI tools make the dentist more accurate at finding decay rather than taking the decision away.

Reshape the role

Move toward a specialty

Specialties such as oral surgery, endodontics and orthodontics centre on complex judgement and hand skill, and in Singapore the specialist title is itself regulated.

Adjacent move

Move into public dental health or clinical governance

Someone has to decide which tools a clinic or health system adopts, check how they perform on its own patients and set the rules for their use — work that needs clinical experience.

Not in diagnosis or treatment. AI has been cleared to help read dental X-rays — one cleared tool raised the dentists' detection of decay in its manufacturer's study — but its clearance says it assists only in detection, is not a replacement for the dentist's review, and should be used only by trained dentists. Treatment is precise hand work that current machines do not do in routine practice, and in Singapore only a registered dentist with a practising certificate may practise dentistry, including radiographic work.

We do not answer that with a number of years, and for this occupation there is a signal you can check yourself: what the AI tools in your practice are cleared to do. As long as their indications say they aid a dentist and are not a replacement for the dentist's review, the diagnosis stays yours. Watch for a tool cleared to diagnose on its own, and for any change to who may lawfully practise dentistry where you work.

For one US-cleared tool, the manufacturer's own study reported that on its own the software detected 72% of decayed surfaces with 98% specificity, and that 13 dentists reading 352 X-rays found 76% of decay with it against 58% without, while their specificity fell slightly from 99.3% to 98.4%. The clearance lists what it misses: decay hidden behind restorations, gross decay, and it can mistake root-canal access for decay. These are one manufacturer's figures on one image set.

The dentist. The cleared tool's own conditions say the final clinical determination is the responsibility of the treating clinician, that the dentist should use all appropriate clinical information, and that the dentist is responsible for reviewing and correcting what the software outlines. In Singapore, practising dentistry at all requires registration and a practising certificate, so the professional answerable for the care is always a named dentist.
