Accuracy and reliability of age estimation from physiological changes of third molars

Popis výsledku v původním jazyce

Aim: Our study aimed to verify the relation between physiological changes of third molar and age of an individual. Material and Method: Our study evaluated 42 ground sections of third molars according to Gustafson' s six criteria method. Patient's age was registered at time of extraction of third molar. We recorded level of attrition, secondary dentine deposition in pulp, changes in periodontium, cementum apposition, root resorption and root translucency. Each factor was alloted a score regarding degree of changes in the tooth. Total score was calculated and transferred to the estimated age according to Gustafson's formula. A regression line was drawn from known age and the total score to create a new regression formula. A standard error of 5.38 and 5.33 years was obtained with Gustafson's formula and newly derived formula, respectively. Conclusion: Third molars are considered the most variable teeth in dentition. Although Gustafson suggested the usefulness of this method ideally in single rooted teeth, we found a singnificant correlation between physiological changes of third molars and age of an individual. In conclusion, despite of its variability third molar can be used for forensic purposes of age estimation in cases with no other tooth available.
