  • Molar - Incisor Hypomineralization (MIH) and long - term exposure to 25 - hydroxyvitamin D, measured as Bone Mineral Density (BMD) in adolescents from Northern Norway: an epidemiological study based on the Tromsø study: “Fit Futures” 

    Dekkerhus, Kristin Adelaide (Master thesis; Mastergradsoppgave, 2020-05-20)
    Aims: The basis of the study was to evaluate if MIH could be related to low levels of vitamin D. Vitamin D is understood to have a key role in both enamel and dentin formation, and maturation, in addition to skeletal integrity. BMD could give a clue of the participants’ long - term vitamin D exposure, indirectly giving a reflection of a possible vitamin D impact on enamel mineralization. Materials ...
