The estimation and assessment of dental age are regularly carried out today in clinical dental work, in forensic analyses of living persons and cadavers, and in archaeological analyses of found human remains. The methods used for dental age assessment in archaeological remains are mostly similar to the methods used today for dental age assessment in modern populations. We can divide them into destructive and nondestructive methods. Nondestructive methods are used more often because they do not lead to tooth destruction, and it is known that archaeological samples are very valuable because they are rare. Changes in the teeth due to aging compared to bone changes and the methods used to estimate age yield more accurate results. Methods for assessing dental age applicable in adults can be divided into morphological and radiological techniques. Although there are many methods available, it is recommended to use only methods based on nondestructive analysis of the sample in bioarchaeological research. Therefore, macroscopic methods are the age estimation methods most often used by anthropologists and bioarchaeologists. The four most common nondestructive age assessment methods are as follows: analysis of palatal suture closure, occlusal tooth wear, tooth root translucency, and pulp/tooth surface ratio. This chapter describes destructive and nondestructive methods that can be used to estimate dental age in archaeological remains. However, preference is given to nondestructive methods such as Kvaal, Bang and Ramm, and Cameriere.
