Abstract

We investigated the possible cariostatic effect of strontium in the absence of effective amounts of fluoride by relating the DMFT index of the population to the strontium and fluoride concentrations in drinking water and enamel surfaces. The epidemiological survey was conducted in two neighboring districts in the northwest part of Greece, involving 582 children ranging in age from 11 to 14. The average DMFT values were 5.26 in the high-strontium (2.9-7 ppm Sr) area and 6.95 in the low-strontium (0.2-1.3 ppm Sr) area, while fluoride was low (less than 0.06 ppm) in both districts. Further, the average strontium concentration in surface enamel was higher in the high-strontium area.

摘要

我们通过将人群的DMFT指数与饮用水和牙釉质表面的锶及氟浓度相关联，研究了在缺乏有效量氟的情况下锶可能的防龋作用。流行病学调查在希腊西北部相邻的两个地区进行，涉及582名年龄在11至14岁之间的儿童。在高锶（锶含量为2.9 - 7 ppm）地区，平均DMFT值为5.26；在低锶（锶含量为0.2 - 1.3 ppm）地区，平均DMFT值为6.95，而两个地区的氟含量均较低（低于0.06 ppm）。此外，高锶地区表面牙釉质中的平均锶浓度更高。
