DNA Fingerprinting is a way to identify a certain individual, rather than simply identifying a species or a particular trait.

Comparative identification:in which the postmortem dental records are compared with the antemortem records of an

individual.

Obtainment of dental information: to narrow the search for an individual when the antemortem records are not available and there are no possible data referred to the identity of the subject.

Identification of victims following mass disasters or catastrophes.

Dentists are respected widely

as a source of valuable data

that can be used to answer

questions that arise during a

death investigation.

Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. The aim of this study is to establish the uniqueness of lip prints which aids in personal identification.

Cheiloscopy helps in identifying

the humans based on the lips’

traces. The pattern of wrinkles on

the lips has individual

characteristics like fingerprints.

Recently, teeth have been the subject of DNA studies as the dental hard tissue which physically encloses the pulp and offers an anatomical configuration of great durability.

Moreover, when morphologically evaluated, even a single tooth provides valuable information regarding the individual to whom the tooth belongs.Pulp tissue is the most widely used option, since it is normally abundant and is less vulnerable to contamination by non-human DNA.

Soft tissue within coronal and radicular pulp chamberconsists of odontoblasts, fibroblasts, endothelial cells, peripheral nerves and nucleated components of blood, which are rich sources of DNA.

Extraction of DNA from the human body remains a difficult task and depends upon numerous environmental factors and extraction procedures. DNA from hard tissues like bone and teeth are most stable even after putrefaction of bodies.
