Abstract
Objectives: Estimaiting the dental age of the adult human remains can often be of great importance in forensic identifi cation cases, and also provides valuable data in paleodontology. The aim of the present study was to compare chronological age with estimated dental age by the method according to Johanson, published in 1971. Material and Methods: 140 permanent intact teeth without dental fi llings and/or dental cavity were taken. The known age was ranging from 18 to 80 years. The average age was 45 years. For the dental age estimation the method according to Johanson was used. Every tooth was subject to longitudinal section of the midpulpal area in a vestibulo-lingual plane. Six variables were analyzed: secondary dentin, attrition, cementum apposition, root resorption, periodontal recession, and root translucency. The results of the chronological and the estimated age have been statistically compared using Person’s correlation coeffi cient and regression analysis. Results: The results showed strong correlation coeffi cient r=0.85; p<0.001 between chronological and determinated dental age. Age determination on samples of teeth between genders is in signifi cant correlation with known age. Correlation coeffi cient was 0.99 for male, and 0.98 for female samples (p<0.001) Conclusion: The method used in this research is the method of choice for dental age determination on exhumed bodies and skeletal remains for forensic and anthropological analysis in Croatia.
