Abstract
- Forensic odontologists often confront with conceptually simple medicolegal question of whether an individual is a juvenile or an adult. The demand for additional research into extending dental age estimation methods in late adolescence is never the less, especially in those who have passed 15 years and are suspected older than 18 years. The present research investigated the regressive dental characteristic, i.e. radiographic visibility of the root pulp in mandibular second molars for the purpose of age assessment, especially for determining the age over 18 years. Nine hundred thirty-six orthopantomograms comprised of 436 males and 500 females aged from 14 to 22 years were examined. Descriptive statistics were performed for each stage in both sexes. The correlation statistics revealed that there is a strong, positive correlation between the chronological age and root pulp visibility stages. The analysis revealed that stage 0 occurred first at the age of 14 years in both sexes. Stage 1 first occurred at the age of 14.26 years in females and 14.74 years in males. Stage 2 was first achieved at the age of 18.6 and 15.2 years in males and females, respectively. The suitability of the studied characteristics in mandibular second molars for age estimation could be confirmed but of limited value. The presence of this stage 2 root pulp visibility in male subjects represents a potential criterion for indicating the age over 18 years. In future studies, the pattern of secondary dentin formation in other tooth types should be investigated. [ABSTRACT FROM AUTHOR]
