Target exams

Red flags

• Facial, submandibular or cervical swelling with trismus, dysphagia or dyspnoea arising from a necrotic tooth — a deep-space odontogenic infection that can threaten the airway; assess and secure the airway, give intravenous antibiotics with anaerobic cover and refer urgently to dental or maxillofacial surgery.
• A child with severe early childhood caries and facial swelling, fever, difficulty swallowing or disturbed sleep — a spreading periapical abscess needing urgent dental or emergency care, not routine recall.
• Rapidly progressive, widespread caries in a young child associated with failure to thrive — severe early childhood caries warranting urgent dental referral and a child-protection consideration when oral neglect is plausible.
• An acutely tender, mobile tooth with a draining gingival sinus and systemic upset — a periapical abscess that will not resolve without drainage and source control.

Care settings

Clinical exam formats

Board mappings

• General Paediatrics and Oral Health: dental caries as the commonest chronic disease of childhood, the AAPD case-definition of early childhood caries, and the fluoride, diet and dental-home prevention pillars.
• Infectious diseases and prevention: recognition of the spreading odontogenic infection as an emergency, and the role of community water fluoridation and fluoride varnish in prevention.
• Renewed curriculum — Oral Health and Public Health: the biofilm ecological-plaque pathophysiology, the demineralisation-remineralisation cycle, and the evidence base for 1000 ppm and above fluoride toothpaste, fluoride varnish and silver diamine fluoride.
• Regional practice: the disproportionate early-childhood-caries burden in remote and Indigenous communities, and the community water fluoridation and fluoride varnish programmes that address it.
• General Paediatrics: recognition of early childhood caries and developmental enamel defects, the age-specific fluoride toothpaste and fluoride varnish guidance, and the first-birthday dental home.
• Public health: community water fluoridation at an optimal 0.7 mg per litre, sugar reduction, and antibiotic stewardship in odontogenic infection.
• Long Case / Structured discussion: a child with early childhood caries — definition and classification, caries-risk assessment, the stepwise prevention and management ladder, and the developmental enamel defect differential.
• Communication station: explaining to a parent the twice-daily fluoride toothpaste, spit-not-rinse and first-birthday dental visit messages, and when toothache becomes an emergency.
• Level 2 / 3 — Oral Health: dental caries and early childhood caries, the fluoride and dietary prevention, and the red flags of spreading odontogenic infection.
• Public health and health improvement: community water fluoridation, supervised toothbrushing programmes, sugar reduction and health-inequality awareness.
• Foundation of Practice (FOP): the causes and risk factors of dental caries, the AAPD definition of early childhood caries, and the developmental enamel defects.
• Applied Knowledge in Practice (AKP): the age-specific fluoride toothpaste, fluoride varnish and silver diamine fluoride guidance, and the emergency recognition of spreading odontogenic infection.
• History-taking and management: the child with early childhood caries or a developmental enamel defect, the oral examination, and the prevention and analgesia plan.
• Communication: explaining twice-daily fluoride toothbrushing, the spit-not-rinse message, a healthy diet, and the emergency features that require same-day review.
• General Pediatrics Content Outline: dental caries and early childhood caries, fluoride prevention, and the developmental enamel defects including molar-incisor hypomineralisation.
• Infectious Diseases and Preventive Pediatrics: the spreading odontogenic infection, the USPSTF fluoride varnish recommendation, and community water fluoridation.
• Patient Care: evidence-based prevention and stepwise management of dental caries, with prompt recognition of the spreading odontogenic infection.
• Systems-Based Practice and Population Health: community water fluoridation, supervised toothbrushing programmes, sugar policy, and reduction of oral-health inequality.
• Medical Knowledge: the biofilm ecological-plaque pathophysiology, the critical pH and demineralisation-remineralisation cycle, and fluoride pharmacology.
• Medical Expert: dental caries diagnosis and prevention, the developmental enamel defect differential, and the emergency recognition of spreading odontogenic infection.
• Health Advocate and Collaborator: community water fluoridation, supervised school toothbrushing programmes, and reducing oral-health inequality in Indigenous and disadvantaged communities.
• Communicator: explaining fluoride toothpaste and varnish, healthy diet, and when toothache becomes an emergency, to families.
