Caries development in children from 1.5 to 3 years of age: a longitudinal study.
This study was designed as a prospective clinical caries prevalence study starting with children at 1.5 years of age. The subjects were 374 children who were born between 1989 and 1991. All subjects visited a public health center in Kunitachi-city, Tokyo, at 1.5 years, 2 years, and 3 years of age. All the children and parents have followed preventive dental care guidance. Dental caries were always examined by one of the authors. The caries prevalences at 1.5 years, 2 years, and 3 years of age were 6.1%, 14.7%, and 31.8%, respectively. The mean dft at 3 years of age in children who developed caries before 2 years of age was significantly greater than that in children caries free at 2 years of age. The findings from the current study showed that children who develop caries before 2 years of age are at greater risk for dental caries.
