Association of Dental Caries in School Children with Hardness of Communal Water Supplies

Effect of Dental Caries on Children Growth

“…A number of nutritional factors, which may be factors in growth and development such as Vitamins A and D, water hardness and protein, have been hypothesised as potentially linked to dental caries (Mellanby & Pattison, 1928;East, 1941;Aptone-Merced & Navia, 1980). However, there is little evidence to substantiate that the systemic effects of poor nutrition increase the risk of dental decay, and it is generally accepted that while diet can have a profound local effect on erupted teeth, it has much less effect while the teeth are forming (Rugg-Gunn, 2000).…”

The effect of geochemical factors on prevalences of dental diseases for prehistoric inhabitants of the state of Missouri

“…In addition, there are interactions between strontium and calcium and among copper, molybdenum, and sulfur with manganese possibly antagonizing the interaction between copper and molybdenum (Underwood, 1977). Interactions between magnesium and carbonates, phosphates, fluoride, barium, calcium, and strontium have also been proposed (Featherstone, 19831, and it has been suggested that water hardnesses (Adler and Straub, 1953;Bowen et al, 1977;East, 1941) and water buffering capacities (Bowen et al, 1977) affect caries incidences. Therefore, it is essential that multiple geochemical factors and their combinations be considered in studies of etiologies of dental diseases; yet it has been only recently that the necessary analytical and statistical techniques have become commonly available.…”
