Comparative Analysis of Deciduous Teeth Eruption and Ossification of Carpel Bones of Hand for Age Estimation
Abstract
Objective: To determine accuracy of age estimation by comparison of deciduous teeth eruption and ossification of carpal bones of hand.
Study Design: Randomized controlled trial study.
Place and Duration of Study: This study was conducted at the Department of Forensic Medicine, Govt. KMSMC Sialkot in collaboration of Radiology Department, THQ Hospital Pasrur, District Sialkot from 25th August 2019 to 25th August 2020.
Materials and Methods: One hundred and forty children of both genders with ages 5 to 15 years were enrolled in this study. All the patients were equally divided into two groups, each group consist of 70 patients. In group A dental age estimates were made using radioscopic (RVG) pictures of the left quadrant mandibular teeth by Demirjian method and the right hand wrist radiograph by Greulich and Pyle method was used for the estimation of the age of the skeleton in Group B. Statistical analysis on differences between chronological age and approximate skeletal and dental age was carried out.
Results: There were 40 (57.14%) male and 30 (42.86%) females in group A and in group B, 38 (54.29%) male and 32 (45.71%) females. The difference between chronological age and dental age in children with ages 5 to 10 years was 0.64±1.24 years and children with ages 11 to 15 years the difference was 0.67±0.18 years in group A and in group B difference between chronological age and skeletal age among children with age group 5 to 10 years was 0.72±1.18 years and among children with ages 11 to 15 years the difference was 0.66±1.18 years. No significant difference was observed between both groups with p-value >0.05.
Conclusion: Both procedures dental age estimation and skeletal age estimation are effective for forensic age estimation. No significant difference was observed between both methods, but the combination of both methods for age assessment in children provides us more accurate age with very narrow range.
