Dental age estimation, quality assurance and age estimation of asylum seekers in Norway.

The historical development of age estimation and the different techniques are presented. Also it is important to separate individuals below 20 years where tooth development can be used and those above 20 years of age where regressive changes must be used and where the visual assessment may be more important. The recommendations for quality assurance from the International Organization for Forensic Odonto Stomatology (IOFOS) is discussed and also the problems of quality assurance on an international level. Suggestions for changes in these recommendations are presented. Finally the Norwegian dental age estimation project in asylum seekers who claim to be below 18 years of age is described.
