Clinical Judgement and Reasoning in Australian Dental Practice
The Australian practice frame
Registration, scope and conduct flow from AHPRA and the Dental Board of Australia. Scope of practice follows competence and training, not job title. You must know consent (voluntary, informed, specific, given by a person with capacity - a signature is evidence of consent, not consent itself), privacy and record-keeping, mandatory notification, infection control standards, and culturally safe care, including for Aboriginal and Torres Strait Islander patients. Recall intervals, the Child Dental Benefits Schedule and state public dental schemes surface in questions about access and equity.
Reasoning under uncertainty
A workable sequence: history, red flags, problem list, differential, investigation, plan, review. Time-critical conditions - airway threat, spreading odontogenic infection, avulsed permanent tooth, uncontrolled haemorrhage, facial trauma, suspected malignancy, safeguarding concerns - outrank everything else on the list.
Traps
- Anchoring on the diagnosis the patient arrives with.
- Ordering a test whose result would not change management.
- Believing referral discharges your duty: communication and follow-up remain yours.
- Working outside scope because no one else is available.
- Ignoring the social and financial context that determines whether a plan is achievable.
Worked example
A 12-year-old avulses an upper central incisor at sport. Handle it by the crown, rinse briefly in saline or milk, replant immediately if the socket is intact, apply a flexible splint for about two weeks and refer for endodontic assessment. Rule of thumb: minutes of extra-oral dry time predict prognosis, so replant first and telephone second.
