Supplementary micronutrients and oral health

Published on May 25, 2012 by

Supplementary micronutrients important to oral health are copper, molybdenum, and vanadium. Copper is required in the formation of cross-linkages in collagen and elastin, and may play a role in the inflammatory response. A deficiency results in a decrease in the tensile strength of collagen and osteoporotic-like bone lesions. Molybdenum is important in the growth and development of alveolar bone, dentin, and enamel; and vanadium is required for cellular metabolism, healthy bone and tooth development. Minerals involved in the calcified tissues include boron, calcium, manganese, silicon, zinc, copper, and magnesium.  A recent epidemiologic study using the NHANES III data found the risk of periodontal disease was 56% greater in women with dietary intakes of calcium below 500 mg/day and 27% greater for those taking in less than 800 mg/day. Zinc is important for its effect on protein synthesis including DNA and RNA synthesis.  Zinc concentrations increase around the wound margin during formation of granulation tissue, scar formation, and re-epithelization. Zinc, copper, and iron all compete for absorption so they need to be kept in balance for optimum wound healing.  Supplementation of minerals above the recommended daily allowance (RDA) is not recommended at this time.
