Evaluation of the Relationship between the BMI and the Sequence and Chronology of Eruption in Permanent Dentition in Spanish Population

Abstract

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.

Corporeal-composition indicators, and physiological alterations in dental eruption

“…Also, in a recent study on a population of 725 pediatric patients aged between 4 and 14, no alterations to the eruption sequence of permanent teeth, nor influence on the teeth present was found. In this study the researchers concluded that bodyweight, height, age, and BMI act as significant predictors of dental eruption symmetry [20]. It is well known that factors such as deficient mastication, diet, and hormonal factors, among others, influence dental eruption; the correlation of said factors to dental eruption is yet to be determined.…”

“…The same correlation was not found when permanent mandibular molars were considered. In the same way, Paz-Cortez 2022 showed that BMI category did not influence tooth eruption among children betweem 4 and 14 years of age ( 15 ).…”

“…After the cited systematic review, other studies were published with conflicting results. While some authors found that increased body weight was associated with early tooth eruption and advanced dental age ( 11 - 14 ), others revealed contradictory evidence, such as lack of association ( 15 ) or an inverted relationship ( 16 ). Paz-Cortez, 2022 when evaluating a sample of patients between 4-14 years old, showed that body mass index (BMI) did not influence tooth eruption ( 15 ).…”

Paz-Cortez, 2022 when evaluating a sample of patients between 4-14 years old, showed that body mass index (BMI) did not influence tooth eruption ( 15 ). In the same way, tooth eruption was delayed with increasing BMI in Indian children aged 6-7 years ( 16 ).…”
