Question 1

What is the aetiology of molar incisor hypomineralisation (MIH)?

Accepted Answer

Multifactorial: systemic insult during enamel mineralisation in early childhood (0–4 years)

Answer

MIH results from a systemic disruption to ameloblast function during the maturation phase of enamel mineralisation (approximately 0–4 years), with many possible precipitating factors.

Question 2

What is the first-line management for hypersensitive first permanent molars affected by MIH?

Accepted Answer

Desensitising agents, fissure sealants, and remineralisation paste

Answer

MIH-affected molars with sensitivity and early breakdown are initially managed conservatively with desensitising toothpaste, casein phosphopeptide remineralisation, and resin-based fissure sealants.

Question 3

At what age should a child first attend a dental appointment according to current UK guidelines?

Accepted Answer

As soon as the first tooth erupts or by age 1

Answer

UK guidance recommends the first dental visit as soon as the first primary tooth erupts or by age 1, establishing dental home, providing preventive advice, and detecting early caries or anomalies.

Question 4

What is the recommended technique to minimise dental anxiety in a child undergoing their first restoration?

Accepted Answer

Tell-Show-Do technique with positive reinforcement

Answer

Tell-Show-Do (explain, demonstrate, perform) combined with positive reinforcement (praise) is the gold standard for behaviour management in paediatric dentistry to build trust and reduce anxiety.

Question 5

What is the significance of an infra-occluded primary molar?

Accepted Answer

Potential space loss and tipping of adjacent teeth; may require extraction if severe

Answer

Infra-occlusion (submerged primary molar/ankylosis) can lead to space loss as adjacent teeth tip into the space and the opposing tooth over-erupts; severe cases require extraction with space maintainer.
