Forensic age estimation is an important element of anthropological research, as it produces one of the primary sources of data that researchers use to establish the identity of a person living or the identity of unknown bodily remains. The aim of this study was to determine if the chronology of third molar mineralization could be an accurate indicator of estimated age in a sample Brazilian population. If so, mineralization could determine the probability of an individual being 18 years or older. The study evaluated 407 panoramic radiographs of males and females from the past 5 years in order to assess the mineralization status of the mandibular third molars. The evaluation was carried out using an adaptation of Demirjian's system. The results indicated a strong correlation between chronological age and the mineralization of the mandibular third molars. The results indicated that modern Brazilian generation tends to demonstrate an earlier mandibular third molar mineralization than older Brazilian generation and people of other nationalities. Males reached developmental stages slightly earlier than females, but statistically significant differences between the sex were not found. The probability that an individual with third molar mineralization stage H had reached an age of 18 years or older was 96.8-98.6% for males and females, respectively. 相似文献

Abstract: Anyone who has followed the evolution of six European nations from a simple Coal and Steel Community to the current twenty‐five Member State European Union (EU), has witnessed a truly remarkable passage. Nonetheless, the EU remains a decidedly jerrybuilt affair. Through numerous enlargements, increased competences, changes in structure and operation, the Union has been bedevilled by the fact that it is neither a simple international treaty with 25 signatories, nor a truly federal union. Rather, the EU has operated, sometimes effectively, often shakily, between these two extremes; exhibiting a sort of ‘fear of federalism’. From a US perspective, this article looks at the present state of the European Union and asks why it has met its potential in some ways, but has fallen so far short in others. Obviously, the tension between the Member States and the Community institutions is one reason. The article asks why do the states compete so much with one another, when their true competition is often with non‐European entities? Why does the European Council never seem to act in a timely manner? Why do euro‐citizens have so poor of an appreciation of what the Community does for them? Why does the Common Agricultural Policy, which contributes such a small amount to European gross domestic product, so dominate the EU budget and agenda? Can the euro, clearly the world's second currency after the US dollar, ever win over its doubters and harmonise European financial service markets? Does enlargement improve or threaten the future of the Community? And can its Common Foreign and Security Policy ever be successful if it is forced to compete with parallel politics in the Member States? All of these questions are addressed in this article with the hope that, through an external critique, the EU will live up to its potential both at home and abroad. 相似文献
