Human identification is a challenging task in forensic odontology. Dental evidence can be used as the sole method of identifying a deceased person. In circumstances where identification of an individual by fingerprint or dental record comparison is difficult, palatal rugae may be considered as an alternative source. Palatal rugae have been shown to be highly individual and consistency in shape throughout life. The present study evaluated the use of palatal rugae patterns for forensic identification using manual method.
In the present study the impression of maxillary arch of 100 individuals were taken. Two casts were prepared for each individual using dental stone. Five evaluators including 2 dentists, 2 forensic medical experts and 1 general surgeon were asked to match the casts. Each evaluator was asked to match the 2 sets of100 casts i.e. 100 casts which were designated by numbers and their 100 counterparts which were designated using codes.
4 evaluators got 100% accurate matching and 1 evaluator got 98% accurate result.
The present study supports the fact of individuality of the rugae. Manual method has given very good results to support the individualization of rugae. Through our study we feel that palatal rugae patterns will be of great use in the future of forensic odontology.

Plastination is a technique used in anatomy to preserve bodies or body parts. In this process, water and lipids in biological tissues are replaced by polymers such as silicone, epoxy or polyester, which are subsequently hardened, resulting in dry, odorless and durable specimens. The two main sources of human organs are the biopsy specimens and from autopsy. Plastinated or embalmated specimens could be an excellent tool in defending cases involving medico-legal issues. This method of plastination allows students to have hands on experience in this field, without exposure to chemicals such as formalin. Many methods have been used as an attempt to decrease the cost and difficulties of the modern plastination techniques. Using polymers for plastination came into existence several years ago. The use of used plastic tea cups for the procedure resulted in resulted in dry, non-toxic, durable, inexpensive, maintenance free, colored, beautiful oral specimen for teaching purpose.Keywords
