title: Advanced dental maturity of Finnish 6- to 12-yr-old children is associated with high energy intake.
abstract: We studied the association of dental maturity with body mass index (BMI), energy intake, and macronutrient intake. A randomly selected subset (n = 148) of the Special Turku Coronary Risk Factor Intervention Project (STRIP) was invited to an oral follow-up study, and the 6- and 12-yr-examination data (n = 111, 60 boys) were used. Food records for four consecutive days and BMI values were extracted from the databank of the main STRIP project. The developmental stage of seven permanent mandibular teeth was assessed using panoramic radiographs. The resulting maturity scores were converted to dental age estimates. Three dental-maturity groups (delayed, average, and advanced) and two BMI groups [normal BMI (≤mean+1SD) and high BMI (>mean+1SD)] were formed. The dental age was higher than the chronological age by 0.6-0.8 yr. Maturity scores for girls were statistically significantly higher than for boys. The distribution of girls into dental-maturity groups at age 12 yr was different from that of the boys and there were more boys than girls among the high-BMI group. Children of the advanced dental-maturity group had a statistically significantly higher energy intake than children in the other groups. We conclude that advanced dental maturity is associated with higher energy intake.
