27.5 Non-Pharmacological Behaviour Management

1. Non-Pharmacological Behaviour Management Techniques

Non-pharmacological behaviour management forms the foundation of paediatric dentistry. Techniques are tailored to the child's cognitive development, emotional maturity, and temperament.

Tell-Show-Do (TSD)

Introduced by Addelston (1959), TSD is the cornerstone of paediatric behaviour guidance:

1. Tell: Explain the procedure in clear, non-threatening, age-appropriate euphemistic terminology prior to introducing any instrument.
2. Show: Demonstrate the instrument and procedure in a benign setting—allowing the child to see, hear, smell, or feel the sensation on an inanimate object or the child's fingernail.
3. Do: Perform the exact procedure without deviation from what was explained and demonstrated.

Other Behaviour Management Modalities

• Positive Reinforcement: Delivering immediate, specific praise following desired behaviour (e.g., "You are doing a fantastic job keeping your hands resting quietly on your tummy!") rather than generic praise. Small rewards (stickers, badges) reinforce positive associations.
• Voice Control: A controlled, deliberate change in pitch, volume, or pacing of the clinician's voice. Used to gain the attention of an uncooperative or disruptive child, establish boundaries, and restore communication. It is never angry, punitive, or abusive.
• Distraction: Diverting attention away from potentially unpleasant stimuli using audiovisual headsets, VR goggles, active storytelling, counting games, or controlled deep breathing exercises.
• Modelling: Bandura's observational learning principle: allowing an anxious child to observe a calm, cooperative sibling, peer, or video demonstration undergoing the identical clinical procedure.
• Enhancing Control (The Stop Signal): Agreeing upon an unambiguous physical signal—invariably raising the left hand—that the child can use to halt the procedure at any point. When the child raises their hand, the clinician must stop immediately, acknowledge the child's concern, and re-establish comfort before continuing. Honouring the stop signal builds trust and reduces perceived helplessness.

Assessing the Child Before Choosing a Technique

Effective behaviour management begins with assessment rather than technique. The examinable variables are the child's age and developmental stage, their previous dental and medical experience — particularly any painful or coercive experience — their temperament, the parent's own dental anxiety, which is transmitted readily, and the urgency and complexity of the treatment required. A three-year-old is not a small adult: pre-cooperative behaviour in a very young child is normal and is not defiance, and expectations must be adjusted accordingly. Anxiety can be measured with validated tools such as the Modified Child Dental Anxiety Scale (MCDASf) and the Venham picture scale, which give a recorded baseline and help track change.

The Core Techniques in Detail

Tell–Show–Do works because it removes uncertainty: the procedure is described in age-appropriate, non-threatening language, demonstrated on a model or a fingernail, and then performed exactly as demonstrated. Breaking the promise made in the "tell" phase destroys the technique's value, which is why euphemisms that later prove false are counter-productive.

Positive reinforcement rewards the specific desired behaviour — "you kept your mouth open really wide, that helped me a lot" — rather than offering generic praise, and is far more effective than criticism. Behaviour shaping reinforces successive approximations to the target behaviour across appointments. Enhancing control gives the child a stop signal and an explicit right to use it, which reduces the sense of helplessness that drives dental fear. Distraction — conversation, counting, music, video — diverts attention during a brief unpleasant stage. Modelling allows a child to watch a cooperative sibling or peer. Systematic desensitisation introduces feared stimuli in graded steps, combined with relaxation, and is the technique of choice for an established phobia. Voice control uses a firm, measured change of tone to gain attention, and must be explained to the parent beforehand to avoid misinterpretation.

Techniques That Are Not Acceptable in UK Practice

This is where examiners concentrate, because practice differs internationally. Hand-over-mouth exercise (HOME) is not acceptable in UK practice. Physical restraint or "clinical holding" may be used only in tightly defined circumstances, with a documented assessment, valid consent from a person with parental responsibility, appropriate training, and a record of the rationale; it is never used simply to complete routine treatment on an uncooperative but healthy child. Any form of coercion, deception or humiliation is a fitness to practise issue.

The examinable escalation is that when behavioural techniques are insufficient, the next step is inhalation sedation, then intravenous sedation in appropriate older patients, and finally general anaesthesia, which must be delivered in a hospital setting with critical care facilities and is justified only where there is no practical alternative. Parental presence is a matter of individual assessment rather than a rule, and the decision should be explained and agreed in advance.
