Age Determination in Manipuri Subjects from the Eruption of Teeth and Epiphyseal Union of Upper Limb

The present study aims to determine the age of the Manipuri population by computing regression formulae from the eruption of the permanent canine & second molar, and also from the epiphyseal union at the elbow and wrist joints. 320 Manipuri subjects of 10 to 15 years (i.e. 244 male, 76 female) coming to the Forensic Medicine department of a tertiary health care hospital at Imphal for age determination from October 2011 to September 2013 were studied. The age of eruption of permanent canines is 10 years in both sexes; whereas the eruption of second permanent molar is 11–12 years in females and 11–14 years in males in the Manipuri population. The medial epicondyle fuses with the shaft of humerus in 11–14 years in both the sexes. The epiphyseal fusions of 1^st metacarpal take place in 13–15 years in females and 1214 years in males. A combined regression formula was calculated for males and females. It can be used as a standard for determination of age in Manipuri subjects by substituting the various stages of dental eruption or epiphyseal union.
