Identity is central to an individual’s personality and his/her existence. The
face is synonymous with identity. Identity needs to be proven in daily life transactions
for security reasons. Identity (be it of the victim or the suspect) is also a paramount
investigative question for which the answer is not straightforward. The orofacial region
is packed with individualistic information ready to be explored in different areas, such
as disasters, crimes, civil matters, and access to property (biometrics). The orofacial
structures offer diverse solutions to the common questions of identity. The choice of a
specific technique is governed by the circumstances that call for identification and the
advantages-disadvantages of the technique.
