Abstract
The present study assessed the suitability of pulp/tooth volume ratio of mandibular canines for age prediction in an Indian population. Volumetric reconstruction of scanned images of mandibular canines from 140 individuals (aged ten - 70 years), using computed tomography was used to measure pulp and tooth volumes. Age calculated using a formula reported earlier for a Belgian sample, resulted in errors > ten years in almost 86% of the study population. The regression equation obtained for the Indian population: Age = 57.18 + (- 413.41 x pulp/tooth volume ratio), was applied to an independent control group (n = 48), and this resulted in mean absolute errors of 8.54 years which was significantly (p < 0.05) lower than those derived with the Belgian formula. The pulp/tooth volume ratio is a useful indicator of age, although correlations may vary in different populations and hence, specific formulae should be applied for the estimates.
摘要
本研究评估了下颌尖牙的髓腔/牙齿体积比在印度人群中用于年龄预测的适用性。使用计算机断层扫描对140名个体（年龄在10 - 70岁之间）的下颌尖牙扫描图像进行体积重建，以测量髓腔和牙齿的体积。使用先前报道的针对比利时样本的公式计算年龄，结果显示在几乎86%的研究人群中误差超过10岁。为印度人群获得的回归方程：年龄 = 57.18 + （-413.41×髓腔/牙齿体积比），应用于一个独立的对照组（n = 48），这导致平均绝对误差为8.54岁，显著低于（p < 0.05）使用比利时公式得出的误差。髓腔/牙齿体积比是年龄的一个有用指标，尽管不同人群中的相关性可能有所不同，因此，应使用特定公式进行估计。
