Estimation of age by Secondary dentin deposition, Root translucency and cementum apposition - A unique modification of Gustafsons method

Abstract

Introduction: The estimation of age at the time of death is often an important step in the identification of human remains. If the age can be accurately estimated, it will significantly narrow the field of possible identities that will have to be compared to the remains in order to establish a positive identification. Recent research shows that Secondary dentin deposition, root translucency, and cementum apposition in a combination may be used more reliably than the combination of six factors (attrition, periodontitis, root resorption, secondary dentin deposition, root translucency, and cementum apposition). Materials and Methods: A study sample consisted of 95 patients undergone extraction, extracted teeth were collected and utilized for ground sections, sections were grinded until the thickness of 1-mm, on this thickness root translucency was noted, teeth were further undergone grinding up to 0.25 mm thickness afterward they were viewed under microscope for secondary dentin deposition and cementum apposition. Results: By using the combination of these three factors for age estimation we got a mean error of ±4.51. Discussion: Present study is confirmed that secondary dentin deposition, root translucency, and cementum apposition are more reliable factors or strictly age-related factors and provides many accu rate results.
