Demineralized thin sections (7\u03bcm) stained with hematoxylin were used. The correlation (r) between age and adjusted count (number of annulations added to age of tooth eruption) was 0.78 for the entire sample (N = 73) and 0.86 for a subsample in which teeth with periodontal disease were excluded (N = 55). Standard error of the estimates ranged from 4.7 to 9.7 years depending on sex and health status of the tooth. The technique provided significantly better estimates for females than for males. The overall inaccuracy (mean absolute error) of the technique was 6.0 years, with a bias (mean error) of 0.26 years. Reduced major axis regression of adjusted count on age produced a slope of 0.797 for the entire sample and 0.889 for the nonperiodontal disease subsample. These slopes are consistent with a hypothesis of annual deposition of cementum rings given a decrease in cementogenesis with increasing age.<\/jats:p>","DOI":"10.1002\/ajpa.1330710307","type":"journal-article","created":{"date-parts":[[2006,2,3]],"date-time":"2006-02-03T22:55:27Z","timestamp":1139007327000},"page":"321-330","source":"Crossref","is-referenced-by-count":96,"title":["Cementum annulation and age determination in <i>Homo sapiens<\/i>.
