Early childhood caries in an uncooperative four-year-old with asthma and a long journey to care
A 4-year-old boy is brought by his mother with a two-month history of pain on eating and frequent night waking. He has cavitated caries in all four maxillary incisors, the maxillary right first molar and both mandibular second molars; the upper right central incisor has a sinus tract and is mobile. He has never seen a dentist, cries and clings to his mother, and will not sit in the chair. He has mild asthma, uses salbutamol about twice a month and has never been hospitalised for it. The family travels three hours from a hill district; the mother says they can come maybe once and asks that all treatment be finished the same day. He drinks sweetened tea from a bottle at night and eats biscuits daily.
1. How do you decide between chairside treatment with behaviour guidance, conscious sedation and general anaesthesia? Which factors dominate in this child?
Read the worked answer
The decision is a balance of disease severity, the child's developmental and behavioural stage, medical status, and the family's ability to return.
- Disease severity and amount of treatment. Seven affected teeth, one with a sinus tract and mobility, means pulp therapy or extraction plus restorations on multiple quadrants. That is far beyond what a four-year-old at Frankl scale 1 will tolerate across repeated visits.
- Behaviour. Age four with no prior dental experience and marked anxiety makes chairside completion unlikely, and forcing treatment risks dental fear and injury.
- Medical status. Mild, well-controlled asthma does not contraindicate general anaesthesia, but it does mean avoiding a recent upper respiratory infection, ensuring good inhaler technique and obtaining physician input. It also argues against aspirin and against unnecessary sedative combinations.
- Access. A three-hour journey and a probable single visit make a definitive single-session approach under general anaesthesia the most realistic way to deliver comprehensive care; staged chairside care would likely fail and leave infection untreated.
My plan is therefore to treat pain and infection today with simple measures, refer for comprehensive care under general anaesthesia, and start prevention immediately so that the same disease does not recur.
2. What do you do at today's visit if he will not cooperate, and what are the immediate clinical priorities?

The priority is to remove the source of pain and infection without creating a traumatic experience.
- Assess and explain: take a focused history, check for fever, facial swelling and submandibular nodes, and explain to the mother what will and will not be attempted today.
- Behaviour guidance: tell-show-do, a short appointment, parental presence if it helps, and a reward at the end. Do not begin treatment that cannot be finished.
- The sinus tract tooth is the urgent problem. If he will accept topical anaesthetic and a gentle infiltration, extract the mobile upper right central incisor; if not, do not force it. Instead prescribe analgesia, arrange the general anaesthetic referral as urgent, and give the mother clear return instructions if swelling, fever or difficulty swallowing develops.
- Analgesia: paracetamol at weight-based dosage is the first choice; ibuprofen is generally acceptable in mild asthma unless there is a history of aspirin or NSAID sensitivity, and aspirin must be avoided.
- Antibiotics are not a substitute for removal of the source and are indicated only for systemic involvement, spreading infection or an inability to treat promptly; if used, amoxicillin with metronidazole cover for a defined course.
- Start prevention today: fluoride varnish, stopping the night bottle, and a realistic brushing plan, so the visit is not wasted.
3. Design the prevention plan you would begin today and justify the recall interval and the use of silver diamine fluoride and fluoride varnish.

This child is at high caries risk: early childhood caries with multiple cavitated lesions, a night bottle of sweetened tea, daily biscuits, no previous dental care and a mother who cannot easily return. Restorations alone will fail unless the drivers are changed, so prevention is not an optional add-on.
- Diet: stop the bottle at night and at naps, water only in the bottle, restrict sugary foods to mealtimes rather than grazing, and explain why frequency matters more than quantity.
- Oral hygiene: brush twice daily with a 1,000 ppm fluoride toothpaste, a smear for a child under six, supervised by an adult; night-time brushing is the most important.
- Professional fluoride: varnish 22,600 ppm at each visit, two to four times a year given the risk, with the evidence that it reduces caries increment in high-risk children.
- Silver diamine fluoride 38%: applied annually to arrest active cavitated lesions, especially where the child cannot tolerate restorative care. It is a reasonable interim measure, requires parental consent for black staining, and does not replace pulp therapy where there is pulpal involvement.
- Hall technique for the molar lesions once he is able to cooperate, or under general anaesthesia.
- Recall every three months initially, with radiographs as tolerated, extending to six months only once risk factors are controlled. Three-monthly review also allows reapplication of varnish and early rescue of new lesions.
