Palatal Rugae: Systematic Analysis of its Shape and Dimensions for Use in Human Identification

Establish a person's identity can be a very complex process, one of the main objectives of the forensic sciences. The analysis of the teeth, fingerprints and DNA comparison, are probably the most used technics, allowing fast and secure identification processes. However, these techniques can not...
