DACTYLOGRAPHY

DACTYLOGRAPHY

Dactylography is the process of taking the impression of the papillary ridges of the fingertips to identify a person.

 MEDICOLEGAL IMPORTANCE

1. Identification by this method is absolute because ,the distribution of ridge pattern is extremely divergent in different persons. So, no two fingerprints can be identical.

·the pattern remains unchanged throughout his life

·it is invariably found at the scene of crime, which can be studied

2. Fingerprints can be taken even from highly decomposed bodies.

3. Fingerprints can be taken from mummified & saponified body.

4. The age of the fingerprints can be measured by the migration of Cl-ion.

5.Millions of fingerprints can be stored so that whenever necessary, the desired print can easily be identified for studies.
