The aim was to analyze the relationship between BMI (body mass index) and the sequence and chronology of the eruption of permanent teeth in a sample of Spanish children. Methods: The study design was descriptive, cross-sectional, observational, and epidemiological. Patients of pediatric age were included. Emerged teeth, and patient’s age, race, and sex were recorded. The nutritional status of the child was assessed by calculating the BMI, according to the WHO parameters. Statistical analysis was carried out with a confidence interval of 95%. A prediction model with logistic regression models was obtained. Results: A total of 725 pediatric patients between 4 and 14 years old were analyzed. BMI acts as a predictor variable for eruption symmetry, as it was most frequent in overweight children (p < 0.001). The probability of symmetry in dental eruption increases for South American children, for an extra month of age, and each meter of height. BMI had an influence in the first tooth to appear only in the fourth quadrant. BMI did not seem to influence present teeth, and the sequence of permanent dental eruption was not influenced by the BMI category. Conclusions: Age, weight, height, and BMI act as significant predictors for eruption symmetry. BMI does not produce alterations in the eruption sequence of the permanent dentition.
目的是分析西班牙儿童样本中体重指数（BMI）与恒牙萌出顺序和时间之间的关系。方法：本研究设计为描述性、横断面、观察性和流行病学研究。纳入儿科年龄的患者。记录已萌出的牙齿以及患者的年龄、种族和性别。根据世界卫生组织的参数，通过计算BMI评估儿童的营养状况。进行95%置信区间的统计分析。获得了一个逻辑回归模型的预测模型。结果：共分析了725名4至14岁的儿科患者。BMI作为萌出对称性的预测变量，因为超重儿童中最为常见（p < 0.001）。南美儿童、额外一岁年龄以及每增加一米身高，牙齿萌出对称的概率都会增加。BMI仅对仅在第四象限出现的第一颗牙齿有影响。BMI似乎对现有牙齿没有影响，恒牙萌出顺序也不受BMI类别影响。结论：年龄、体重、身高和BMI是萌出对称性的重要预测因素。BMI不会导致恒牙列萌出顺序的改变。
