Caries patterns in Head Start children in a fluoridated community.

Assessment of caries experience based on the person rather than on the tooth opens the possibility for qualitative descriptions of caries in a population, as well as for the study of specific factors associated with different caries experiences. The study of a Head Start population in adjacent fluoridated communities was divided into two parts. It was the purpose of part one of the study to determine the prevalence of specific caries patterns (presumably associated with different etiologies). Of the children, 39 percent were caries-free; 32 percent had carious lesions only in pit-and-fissure defects of molars; 6.5 percent had carious lesions in hypoplastic defects; 11 percent had facial-lingual lesions, compatible with "nursing caries"; and 11.5 percent had approximal lesions of molars; no child in the study had rampant caries. The second part compared specific lifestyle variables with specific caries patterns. Statistically significant differences or trends were found between caries-free children and those with smooth-surface lesions for mother's educational level, time spent with grandparents, mother's perceived primary reason for cavities, and mother's tendency to permit the child to eat sweets without restriction. No significant differences or trends were found for lifestyle variables between caries-free children and those having lesions associated only with tooth defects.
