To investigate the relationship between fluoride levels in well drinking water, severity of dental fluorosis and dental caries in the Hail region of Saudi Arabia, 2355 rural children aged 12-15 years were examined. Over 90% of the children had fluorosed teeth and chi-square tests showed a strong association (P < 0.001) between fluoride level (0.5-2.8 ppm) in well drinking water and severity of dental fluorosis. Although regression analysis showed a statistically significant relationship (P < 0.001) between fluoride concentration and caries experience, the amount of variation explained was very low (R2 = 0.9%). Since fluoride in well water had little influence on caries experience and is causing dental fluorosis, it should be removed by defluoridation or the rural population should be provided with an alternative source of drinking water with lower fluoride concentration.
为研究沙特阿拉伯海尔地区井水氟含量、氟斑牙严重程度与龋齿之间的关系，对2355名12至15岁的农村儿童进行了检查。超过90%的儿童有氟斑牙，卡方检验显示，井水氟含量（0.5 - 2.8 ppm）与氟斑牙严重程度之间存在强关联（P < 0.001）。尽管回归分析显示氟浓度与龋齿经历之间存在统计学显著关系（P < 0.001），但可解释的变异量非常低（R2 = 0.9%）。由于井水中的氟对龋齿经历影响很小且会导致氟斑牙，应通过除氟处理去除氟，或者应为农村人口提供氟浓度较低的替代饮用水源。
