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.
我们研究了牙齿成熟度与体重指数（BMI）、能量摄入和常量营养素摄入之间的关联。邀请了图尔库特殊冠心病危险因素干预项目（STRIP）中随机抽取的一个子集（n = 148）参加口腔随访研究，并使用了6年和12年检查数据（n = 111，60名男孩）。从STRIP主要项目的数据库中提取连续四天的食物记录和BMI值。使用全景X线片评估七颗下颌恒牙的发育阶段。将得到的成熟度评分转换为牙齿年龄估计值。形成了三个牙齿成熟度组（延迟、平均和提前）和两个BMI组[正常BMI（≤均值+1标准差）和高BMI（>均值+1标准差）]。牙齿年龄比实际年龄高0.6 - 0.8岁。女孩的成熟度评分在统计学上显著高于男孩。12岁女孩在牙齿成熟度组中的分布与男孩不同，高BMI组中男孩比女孩多。牙齿成熟度提前组的儿童能量摄入量在统计学上显著高于其他组。我们得出结论，牙齿成熟度提前与较高的能量摄入有关。
