Violence and crimes against human life, such as bomb explosions, wars or plane crashes, as well as cases of carbonized bodies or in advanced stage of decomposition, among other circumstances, highlight the need to employ ever faster and more accurate methods during the process of identification of victims. DNA (Deoxyribonucleic Acid) is frequently used in identifying individuals or determining the origin of certain tissues. Teeth are resistant against extreme circumstances such as temperature, humidity and acidity, which is an important advantage in DNA analysis. Furthermore an abundance of DNA can be extracted from teeth. Saliva can be obtained in a simple, painless and non­radical way. DNA analysis has proven its value in forensic dentistry, but ethical and juridical considerations are still a matter of debate and criticism.
