Mineral analyses of garden soils, vegetables, and water samples from 21 villages in the Sepik and Fly River regions of the Territory of Papua and New Guinea, in which the mean prevalence of dental caries ranged from 0 to 29.5% decayed teeth per person, have shown the following relationships between variations in the caries prevalence and the amounts of certain elements:(1) A strong inverse association with concentrations of alkali and alkaline earth elements, especially strontium, barium, potassium, magnesium, calcium, and lithium, in garden soils.(2) A possible direct association with concentrations of lead and copper in village garden soils.(3) Consistent evidence of inverse associations with concentrations of vanadium, molybdenum, manganese, aluminium, titanium, and phosphorus and of direct associations with concentrations of lead, copper, chromium, zinc, and selenium in the staple foodstuffs-namely, sago, sweet potato, and Chinese taro.In general, analyses of soils and vegetables from 22 villages in the highlands of Papua-New Guinea have confirmed the soil associations with the caries prevalence reported for villages in the Sepik and Fly River regions.
对巴布亚新几内亚领土塞皮克河和弗莱河地区21个村庄的花园土壤、蔬菜及水样进行的矿物质分析表明，这些村庄的龋齿平均患病率为每人0至29.5%的龋齿，龋齿患病率变化与某些元素含量之间存在以下关系：(1) 与花园土壤中碱金属和碱土金属元素，特别是锶、钡、钾、镁、钙和锂的浓度呈强烈负相关。(2) 与村庄花园土壤中铅和铜的浓度可能呈正相关。(3) 有一致的证据表明，主食（即西米、红薯和芋头）中钒、钼、锰、铝、钛和磷的浓度与之呈负相关，而铅、铜、铬、锌和硒的浓度与之呈正相关。总体而言，对巴布亚新几内亚高地22个村庄的土壤和蔬菜分析证实了土壤与塞皮克河和弗莱河地区村庄报告的龋齿患病率之间的关联。
