Palatal Rugae as an Unique and Stable Marker in Personal identification—An Interracial Pilot Study

Background: In post-mortem scenarios, often it is a very difficult process to establish a person's identity. Rugae are unique in that they are protected from trauma as they are insulated from heat by tongue and buccal pad of fat unlike fingerprint or lip print that is prone to destruction. Aim...

description Background: In post-mortem scenarios, often it is a very difficult process to establish a person's identity. Rugae are unique in that they are protected from trauma as they are insulated from heat by tongue and buccal pad of fat unlike fingerprint or lip print that is prone to destruction. Aim and Objectives: This study was aimed to compare the palatal rugae among people of different races. The sole objectives of the study were to assess the predominant pattern in the selected groups, reliability of rugae pattern in personal identification, to evaluate reliability of sex determination and to compare the total number of rugae on right and left sides of the palate among the males and females. Study Design: A total of 90 subjects were enrolled into the study and divided into three groups that are African, Dravidian and Mongoloid population. Shapes of rugae present were analyzed according to the classification given by Kapali et al. (1997) and Thomas & Kotze (1983). Result: The predominant rugae shape in African and Dravidian population was wavy pattern, whereas Mongoloid race was predominant in curve pattern. African and Dravidian males were predominant in wavy pattern when compared to Mongoloid males where unification type was more predominant. Conclusion: A statistically significant association between the rugae shape in three populations exists, although subtle yet definite.
