As an example of the collaboration of periodontologists and physical anthropologists, the skulls of two Indian populations were studied. A root index to assay periodontal disease and a wear index to evaluate occlusal wear, were developed. The first Indian population, living 400 years ago, had more decay, loss of teeth and caries; the second population, living 4,000 years ago, exhibited more periodontal disease. Starting with a sample of eight teeth, two from each quadrant, the statistical analysis showed that a smaller number of teeth would give a reliable assessment of past oral health. Based on our findings, the canines proved to be good indicators for general wear and the incisors for periodontal disease. A six-tooth index of varying teeth studied is proposed for the root index and the wear index in future studies of oral health of ancient populations.
作为牙周病学家和体质人类学家合作的一个例子，对两个印度人群的头骨进行了研究。开发了一种用于评估牙周疾病的牙根指数和一种用于评估咬合磨损的磨损指数。第一个印度人群生活在400年前，有更多的龋齿、牙齿脱落和龋病；第二个印度人群生活在4000年前，表现出更多的牙周疾病。从每个象限选取两颗牙齿，共八颗牙齿作为样本，统计分析表明，较少数量的牙齿就能对过去的口腔健康状况给出可靠评估。根据我们的研究结果，犬齿被证明是一般磨损的良好指标，而门牙则是牙周疾病的良好指标。在未来对古代人群口腔健康的研究中，针对牙根指数和磨损指数，建议采用一个由不同牙齿组成的六颗牙齿的指数。
