  1. Hyperthyroidism in a dental patient most relevantly affects dental management by:

    Answer: Increasing sensitivity to adrenaline and potential for thyroid crisis

    Hyperthyroid patients are very sensitive to catecholamines; adrenaline in LA solutions can precipitate hypertensive crisis or thyroid storm, necessitating cautious use.

  2. Osteogenesis imperfecta is associated with which oral condition?

    Answer: Dentinogenesis imperfecta

    Dentinogenesis imperfecta type I occurs in osteogenesis imperfecta due to defective type I collagen, producing opalescent discoloured teeth prone to attrition.

  3. Which condition is characterised by episodic severe hypertension, headache and sweating due to excess catecholamine secretion?

    Answer: Phaeochromocytoma

    Phaeochromocytoma is a catecholamine-secreting tumour of chromaffin cells of the adrenal medulla, causing episodic or sustained hypertension with severe headache, sweating and palpitations.

  4. Thrombocytopenia significant for dental practice (increased bleeding risk) is generally considered when platelets fall below:

    Answer: 50 × 10⁹/L

    A platelet count below 50 × 10⁹/L is associated with significantly increased bleeding risk for invasive dental procedures; haematology consultation is advised below this threshold.

  5. Sickle cell anaemia patients face which specific risk during general anaesthesia?

    Answer: Sickling crisis triggered by hypoxia, dehydration or hypothermia

    Hypoxia, dehydration and hypothermia can trigger a sickling crisis in HbS patients; careful perioperative management is essential including optimal oxygenation and hydration.

  6. Leukaemia may present in the oral cavity with:

    Answer: Gingival hyperplasia due to leukaemic infiltration

    Leukaemic infiltration of the gingival connective tissue, particularly in AML (M4/M5 monocytic subtypes), causes diffuse gingival enlargement with a characteristic reddish-purple appearance.
