The present review article is aimed at describing the radiological methods utilized for human age identification.
The application and importance of radiological methods in human age assessment was discussed through the literature survey.
Following a literature search, 46 articles were included in the study and the relevant information is depicted in the article. Dental tissue is often preserved indefinitely after death. Implementation of radiography is based on the assessment of the extent of calcification of teeth and in turn the degree of formation of crown and root structures, along with the sequence and the stages of eruption. Several radiological techniques can be used to assist in both individual and general identification, including determination of gender, ethnic group and age. The radiographic method is a simpler and cheaper method of age identification compared with histological and biochemical methods. Radiographic and tomographic images have become an essential aid for human identification in forensic dentistry, particularly with the refinement of techniques and the incorporation of information technology resources.
Based on an appropriate knowledge of the available methods, forensic dentists can choose the most appropriate since the validity of age estimation crucially depends on the method used and its proper application. The multifactorial approach will lead to optimum age assessment. The legal requirements also have to be considered.
本综述文章旨在描述用于人类年龄鉴定的放射学方法。
通过文献调查讨论了放射学方法在人类年龄评估中的应用和重要性。
经过文献检索，共有 46 篇文章纳入本研究，相关信息在文章中描述。人死后，牙组织通常会无限期保存。放射线照相的实施基于牙齿钙化程度的评估，进而评估牙冠和牙根结构的形成程度，以及出牙的顺序和阶段。有几种放射学技术可用于协助个体和总体识别，包括确定性别、种族和年龄。与组织学和生化方法相比，放射线照相方法是一种更简单、更便宜的年龄鉴定方法。放射线照相和断层扫描图像已成为法医牙科中进行人类识别的重要辅助手段，尤其是随着技术的改进和信息技术资源的结合。
法医牙医可以根据可用方法选择最合适的方法，因为年龄估计的有效性主要取决于所使用的方法及其正确应用。多因素方法将导致最佳的年龄评估。还必须考虑法律要求。
