Objective. To determine which child-rearing practices are associated with nursing caries.

Design. Cross-sectional study.

Setting. Hospital-based general pediatric clinic.

Participants. Sequential sample of 110 healthy children aged 18 to 36 months.

Outcome measures. Feeding practices of children, limit-setting issues, and familial dental health were determined by maternal interview. Nursing caries were diagnosed by dental examination.

Results. Nursing caries were found in 22 (20%) of the children. Ninety percent of children with and without caries were bottle-feeding at 12 and 18 months of age. Ninety-one percent of children with caries and 84% without were still drinking a nighttime bottle at 18 months (P = .33). The mothers of children with caries were found to have fewer years of education, 8.9 vs 10.8 years (P = .02), and were more likely to have eight or more cavities, 55% vs 19% (P = .002). More infants in the caries group had been breast-fed, 72% vs 46% (P = .02), although length of breast-feeding was similar, 5.4 vs 6.7 months. Fewer children with caries drank fluoridated tap water 27% vs 54% (P = .05), but there were no differences in topical fluoride use, dental hygiene practices, or visits to the dentist.

Conclusions. These findings fail to substantiate a straightforward relationship between child-rearing practices and nursing caries and suggest that well-designed prospective studies are need to clarify the etiology of early caries.
