ECC prevention in 0-3 years is described as preventable and reversible.

• A. True
• B. False
• C. Not stated
• D. Sometimes

Answer: (A)

Preventing ECC in very young children hinges on stopping the disease before it cavitates and, in its early stages, even reversing non-cavitated damage. In the 0–3 year age range, prevention is achievable through reducing exposure to fermentable sugars (especially at night), promoting good oral hygiene from the first tooth, and ensuring appropriate fluoride exposure (for example, fluoride toothpaste in the right amounts and professional fluoride applications as advised). When early non-cavitated lesions appear, remineralization can repair mineral loss with fluoride, saliva, and a reduced cariogenic environment, making reversal possible at that stage. The key caveat is that once a lesion has cavitated into dentin, reversal becomes unlikely, so the emphasis remains on preventing disease and catching early signs early. This combination—strong prevention plus potential reversal of early lesions—fits the description, so the statement is true.
