For the estimation of dental development, the Demirjian method was used, and for the skeletal maturation level, the cervical vertebrae maturation method was applied. Multivariate and univariate analyses were performed to examine possible metabolomic variations according to the chronological, dental, and skeletal age. Group differences were evaluated using Kruskal\u2013Wallis tests, with Bonferroni correction applied to account for multiple comparisons. Spearman\u2019s \u03c1 correlation coefficient was used to examine variable correlations. Metabolite expression variations were visualized using boxplots.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In total, 63 compounds were retrieved with metabolomic analysis. The results showed that cadaverine and L-valine uniquely displayed robust dental age-related variation, demonstrating significant elevations during tooth development and decrease in the late stages of the dentition. Malonic acid and nonanoic acid decrease with advanced dental age. Regarding bone growth, cadaverine, L-serine, and L-homoserine have been identified as strong indicators of skeletal maturation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Several distinct metabolites showed coherent associations with skeletal and dental maturation.
