Age estimation can help establish the age of an individual, narrow down the search for a missing person, and identify deceased persons. Age estimation is also important in jurisdiction and legal cases. Teeth are used in the age estimation process because of their uniqueness and their durability. Many methods have been developed for age estimation in both living and deceased individuals. Dental imaging can be used to gather information regarding the developmental stages of teeth, information that has been shown to have a correlation with chronological age. The aim of this presentation is to present the role of dental imaging in dental age estimation methods that have been specifically developed for the Thai population and may be applicable to other ethnic populations. These methods can be easily achieved using panoramic radiographs or pariapical radiographs. Examples of cases showing how teeth can predict age will be demonstrated.
