An epidemiological survey of dental caries using modified Moller's index (1966) carried out in 483 children (aged 7-17 years) of rural areas--Talwandi Kalan, Dhanansu and Bhatian (District Ludhiana) of Punjab with almost similar F levels in their drinking water supply, similar socio-economic status, environmental factors/demographic parameters and dietary habits revealed wide variations in the prevalence and severity of dental caries. Further investigation extended to evaluate the concentrations of various trace elements Se, Li, Zn, Cu, Fe and Mn in drinking water to find out the disparity of dental caries status, revealed that the higher figures of prevalence and severity of dental caries observed in Dhanansu and Bhatian as compared to Talwandi Kalan could be attributed to the presence of Se in drinking water supply of these areas which was not detectable in the water supply of Talwandi Kalan. On the contrary, the concentration of Li in water supply of Talwandi Kalan with low caries was found to be higher compared to that of Dhanansu and Bhatian with higher dental caries in children population.
在旁遮普邦卢迪亚纳地区塔尔万迪卡兰、达纳苏和巴蒂安（农村地区）的483名儿童（7至17岁）中，使用改良的莫勒指数（1966年）进行了龋齿流行病学调查。这些地区的饮用水氟含量、社会经济地位、环境因素/人口参数和饮食习惯几乎相似，但龋齿的患病率和严重程度却存在很大差异。进一步的调查评估了饮用水中各种微量元素硒、锂、锌、铜、铁和锰的浓度，以找出龋齿状况的差异。结果显示，与塔尔万迪卡兰相比，达纳苏和巴蒂安观察到的龋齿患病率和严重程度较高，这可能归因于这些地区的饮用水中存在硒，而塔尔万迪卡兰的供水系统中未检测到硒。相反，在儿童龋齿率较低的塔尔万迪卡兰，其供水系统中的锂浓度高于儿童龋齿率较高的达纳苏和巴蒂安。
