Correct answer: D — Observation with periodic clinical and radiographic follow-up

Discolouration (grey/dark) of a primary incisor after trauma is caused by intrapulpal haemorrhage and haemoglobin breakdown products infiltrating the dentinal tubules. It does not necessarily indicate pulp necrosis — some traumatised primary teeth may revascularise, and the discolouration may lighten over time. If the tooth is asymptomatic with no radiographic pathology (periapical radiolucency, internal resorption), observation with regular clinical and radiographic follow-up (3, 6, 12 months, then annually) is appropriate. Treatment is only initiated if signs of infection or pathological resorption develop.
