The aim of this study was to determine the degree of fluorosis in the primary dentition and the accompanying caries patterns in groups of preschool-children in high and low fluoride areas. Among 331 coloured children, aged 1-5 years, living in an area with water F concentrations ranging from 2.2 to 4.1 parts/10(6), 82% were caries free and the dmft values ranged from 0 to 15 with a mean dmft of 0.8 +/- 2.1. Varying degrees of fluorosis in the primary teeth were present in 50.6% of the children. In 177 coloured children of similar ages from an adjacent area with 0.2 parts/10(6) F in the drinking water the dmft values ranged from 0 to 20 with a mean dmft of 5.4 +/- 5.8. Only 28% of the children were caries free. None of the children in this area had fluorosis. The caries prevalence was significantly higher in the low fluoride area than in the high fluoride area. The degree of fluorosis found in the primary dentition in the children from the high fluoride area was higher than had been anticipated and was accompanied by a very low caries prevalence.
本研究旨在确定高氟地区和低氟地区学龄前儿童群体中乳牙氟斑牙的程度以及伴随的龋病模式。在生活于水氟浓度为2.2至4.1 ppm地区的331名1至5岁有色人种儿童中，82%无龋，dmft值范围为0至15，平均dmft为0.8±2.1。50.6%的儿童乳牙存在不同程度的氟斑牙。在来自相邻地区、饮用水氟含量为0.2 ppm的177名相似年龄的有色人种儿童中，dmft值范围为0至20，平均dmft为5.4±5.8。只有28%的儿童无龋。该地区儿童均无氟斑牙。低氟地区的龋病患病率显著高于高氟地区。高氟地区儿童乳牙的氟斑牙程度高于预期，且龋病患病率极低。
