Abstract: The aim of the study, is to present the historical development of age estimation in adults from teeth. It should be noted that individuals are separated to those who are below 20 years where tooth development can be used and those above 20 years of age where all teeth are fully formed and regressive age related changes might be used. For each technique developed for the second group since 1950, a basic apprehension of the method is given and its application and reliability is discussed. The techniques are categorized in morphological, radiological and biochemical. In order to reach to reliable estimation different techniques should be used and repeated measurements should be made. Recently, the first software program for age estimation was introduced enabling quicker results.
