Sample item

What is the earliest reversible stage of enamel caries?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Subsurface demineralization appearing as a white spot lesion

Early enamel demineralization can appear as a white spot lesion and may be arrested or remineralized through fluoride, plaque control, and dietary measures.

Option by option

  • A. Complete loss of the clinical crown

    Crown loss is a late destructive outcome.

  • B. Subsurface demineralization appearing as a white spot lesion (correct)

    Correct: white spots represent early potentially reversible mineral loss.

  • C. Fracture extending into root dentine

    Root fracture is traumatic rather than early caries.

  • D. Pulpal necrosis with abscess formation

    Pulp necrosis is advanced irreversible disease.
