with and without early childhood caries (ECC). Method: Biofilms of 16 children (7 with ECC;
9 caries free) were exposed to human milk or 10% sucrose solution in the crossover design,
and the biofilm pH was determined. Results: Breastfeeding did not provoke a decrease in
biofilm pH, irrespective of the children's caries status, whereas sucrose decreased the pH for
both groups. In addition, higher ΔpH5min (pH variation occurring at 5 min) was observed in …
