Abstract

The authors have studied the growth and development of mandibular permanent teeth in order to the make basic data that are necessary to determine the forensic age. The 631 subjects whose ages range from 3 years to 18 years were selected to analyze calcification degree of mandibular teeth. The results were as follows: 1. There were significant differences between adjacent ages, except 14-15 years and 17-18 years. 2. In each tooth, these were differences between adjacent ages from 3 years to 10 years, except central incisor and third molars. 3. All teeth were almost completely developed at the age of about 14 years, except second and third molars. 4. In each tooth, there were the widest significances between adjacent ages in premolars.
