Concentration of essential elements in dentine and their relationship with age. (a) Concentration of essential elements in all the teeth (b,c). Concentration of essential elements in men and women teeth (d,e). Concentration of essential elements in the different types of teeth. Each point represents the mean concentration value of each trace element. Comparisons between the different age ranges (<30, 30–50, >50 years) were made by the Kruskal-Wallis test. P < 0.05 was statistically significant. *p < 0.05; **p < 0.01; ***p < 0.001. This figure has been generated using GraphPad Prism 5 software.
