OBJECTIVES: This study sought to determine how dental health and dental health habits change from 3 to 5 years of age and to consider whether preventive dental health care helped in preventing or halting caries in children. METHODS: The study included 67 maternity health care clinics, 72 well-baby clinics, and 69 dental health care clinics. Of the 1,292 newborn children, 1,003 (90.8%) were included in this study. RESULTS: Preventive dental health care contributed to dental caries being halted in only 13.2 percent of those children who had enamel caries at 3 years of age. The dmft index did not increase in 22.6 percent of those children who had dentinal caries at 3 years of age. For all others, the disease became more severe. Toothbrushing habits of 3-year-old children were very consistent over the two years studied. Children were at a risk for caries when their mothers had nine years of basic education, when they already had plaque and caries at 3 years of age, and when the frequency of eating sweets increased the most during the two-year study period. CONCLUSIONS: Among 3-year-old children, plaque is an indicator of caries risk and therefore should be a key element in health education. Those children who already have evidence of caries at 3 years of age should be the target of preventive dental services because of their increased risk.
