A 4-Year-Old Who Refuses to Open Her Mouth After a Previous Restraint
A 4-year-old girl attends a Ministry of Health polyclinic in Hawalli with her mother. She has cavitated lesions on 74, 75 and 84, and 64 has a large occlusal cavity with a history of food impaction and occasional night-time crying, though the mother is unsure whether this is dental. At the first visit she cried before the mouth mirror reached her teeth, clamped her mouth shut and would not sit back in the chair. Eight months ago a previous dentist treated her using a papoose board, and the mother says the child now refuses to open her mouth even at home for toothbrushing. Appointments are 25 minutes and Saturday clinics are heavily booked. Nitrous oxide is available but the clinic requires a second trained assistant, who is rostered only on Tuesday mornings. The general anaesthesia waiting list at the dental hospital is 5 months, and the family travels to Cairo for two months each summer.
1. Rate this child's behaviour and set out a concrete plan for the first appointment, naming the techniques you would use and the ones you would avoid.

Behaviour rating: Frankl 2 - negative, reluctant, will not comply, but not wholly negative or defiant. This is not simple shyness: the papoose-board episode has produced a conditioned fear response, so the goal of visit one is not restorations but rebuilding predictability and control.
First appointment (25 minutes):
- Brief the mother before the child enters, and seat her out of the child's direct line of sight so she does not answer for the child or use threats.
- Tell–show–do on a finger, then on the child's own hand, then the mirror; let her hold the mirror herself so she has something to control.
- Agree a stop signal (raised hand) and honour it every single time - this is the single step that converts a Frankl 2 into a cooperative child over two or three visits.
- Sequence least to most threatening: count teeth, prophylaxis with a paste she chooses, fluoride varnish. No local anaesthetic and no forced radiographs; take a bitewing only if she accepts the sensor.
- Use immediate, specific reinforcement rather than a bribe promised in advance.
- Avoid aversive techniques and any form of restraint: further restraint on top of her existing experience risks lasting dental fear, and restraint requires a separate, explicit consent discussion in any case.
- End on a success and tell her exactly what will happen at the next visit.
Document the rating, what worked and the intended sequence, so the next clinician does not restart from zero.
2. Weigh the realistic options for completing the restorative care - repeated tell-show-do with local anaesthesia in 25-minute slots, nitrous oxide on Tuesday mornings, or general anaesthesia - and state which you would choose and why.
Read the worked answer
The decision hinges on four variables: amount of care, current cooperation, the pulpal status of 64, and the family's logistics.
- Repeated tell-show-do with local anaesthesia in 25-minute Saturday slots is the ideal long-term path but is currently unrealistic: she will not open her mouth, the slots are short and heavily booked, and there are at least four teeth needing care including one that may be pulpally involved.
- Nitrous oxide on Tuesday mornings is the best fit. The child is medically healthy, has no airway obstruction or recent upper respiratory infection, and is old enough to accept a nasal hood once it is introduced with tell-show-do. Nitrous oxide raises the threshold for cooperation enough to allow local anaesthesia and a quadrant per visit. The constraint is structural - the second trained assistant and the Tuesday roster - so the plan must be built around that, not around convenience.
- General anaesthesia is the definitive single-visit option but carries a 5-month wait, an anaesthetic risk in a preschool child, and does not by itself solve the fear; without behaviour work she will still be a frightened patient afterwards.
Plan: book Tuesday morning nitrous oxide visits, treating 64 first (pulpectomy or extraction depending on sensibility and radiographic findings, plus a stainless steel crown) because night pain suggests irreversible pulpitis; then one quadrant per visit. Use the first nitrous visit mainly to acclimatise. If two nitrous visits fail to deliver treatment, place her on the GA list rather than persist with a failing strategy. Oral sedation with midazolam is a fallback only if the clinic has monitoring, fasting protocols and trained recovery staff; it is not a substitute for a properly equipped setting.
3. The mother now insists that everything be completed under general anaesthesia at the next visit and refuses to return for multiple appointments. How do you respond, and what do you document?
Read the worked answer
Explore before you argue. Ask why multiple visits are a problem - work, other children, transport, or fear of the anaesthetic being repeated. Mothers often accept a plan once the reason is named; a Tuesday-morning block booked in advance may solve it.
Explain the trade-offs honestly:
- The GA list is 5 months. Whatever is decided about the operating theatre, 64 is possibly irreversibly inflamed now, and an untreated pulpectomy candidate can become a facial swelling or an emergency at 2 a.m. during the summer travel.
- General anaesthesia is not risk-free in a 4-year-old, and consent for it is a separate discussion with an anaesthetist, not something the dentist can promise at the next visit.
- Interim measures are available: silver diamine fluoride to arrest the cavitated lesions pending definitive care, plus analgesia, which buys time without pretending to be a cure.
Offer a written plan: interim stabilisation now, nitrous oxide quadrant care on Tuesdays, GA referral in parallel if she still prefers it after the consultation - the two paths are not mutually exclusive.
Documentation if she refuses all interim care: record the clinical findings, the options offered, the risks explained (pain, swelling, infection, possible need for emergency care abroad), the fact that the decision is hers and that she declined, using her own words where possible, with date and signature. Document that she was given an emergency contact route. What is not acceptable is documenting a plan that leaves acute infection untreated without any safety net.
