Abstract :

Introduction:

Palatoscopy or rugoscopy is considered to be a study of irregular fious connective tissue ridges located in the anterior part of the hard palate also known as �plica palatina�. In Forensic medicine fingers, �palatoscopy� is considered to be an alternative to �dactyloscopy‘ during identification of individuals in catastrophic accidents. This is because rugae has a more stable anatomic form and also placed in a more secure position sealed anteriorly by incisors and posteriorly by soft palate and inferiorly by tongue. This facilitates the forensic odontologists to identify the rugae pattern, even in third degree burn individuals.

Aim:

The aim of the study is to assess the number of rugae bilaterally present on the primary palate, their patterns, length along with gender differences among patients who visit the outpatientof our hospital

Materials and methods:

A total of 100 participants including 50 males and 50 females above the age of 20 years were included in the study .On their maxillary study models; the palatal rugae were assessed for their number , shape and length of rugae on either side of the palate.

Results:

The variation in number of rugae among males and females were present. In right side 471 and left side 451 rugae were present .Wavy forms (Female –46.30 %, Male – 36.26%) were seen to predominate other forms of rugae.

Conclusion:

Palatal rugae are exclusive for all people hence, palatoscopy is used as an impeccable tool for identification in forensic odontology
