In the described program, what outcome was achieved in children of mothers who received prenatal dental services and prevention education, followed by infant participation and an age 1 dental referral?

• A. Cavities in all children
• B. Cavity-free at three
• C. No change in caries incidence
• D. Partial reduction in caries (e.g., 25%)

Answer: (B)

The key idea is that addressing oral health early for both mother and child—providing prenatal dental care and prevention education, engaging the infant early, and making an age-1 dental referral—can profoundly disrupt the caries process in young children. This combined approach targets transmission of cariogenic bacteria, establishes protective habits, and creates a dental home early enough to prevent decay from developing.

In that context, being cavity-free at age three is the best-supported outcome. Early preventive visits allow use of fluoride and other preventive measures, guidance on feeding and hygiene, and timely referrals, which together reduce the risk of lesions forming during the most vulnerable years. When these steps are implemented, many children reach age three without cavitated lesions, reflecting the successful suppression of caries initiation and progression.

The other options describe less favorable or more modest effects that are not as consistent with the impact of this integrated prenatal-to-age-one prevention strategy.
