Abstract :

Identification of an individual is an important aspect of forensic medicine in addition to which study of the various morphological characteristics of an individual has applications in the field of anthropology. The study of palatal rugae forms an important basis of human identification especially due to mass disasters where routinely used techniques may not be helpful. This study aimed at evaluating the palatal rugae on the basis of shape and size and also the shape of the dental arch and incisive papilla along with the length of mid-palatine raphe and the canine-papilla-canine relation. The study was conducted in 200 individuals (males and females) visiting Dhulikhel hospital, Central Nepal. The results suggested that primary rugae showing wavy shape were the most common pattern in both the gender. Significant differences were observed in curved rugae type between males and females. Primary rugae showed significant differences between males and females on the left side of the maxillary arch. In addition, the most common shape of dental arch was parabolic, incisive papilla showing triangular forms were predominant along with long mid palatine raphe and the most common canine-papilla-canine relation being of the posterior type. It can be concluded that evaluation of palatal rugae along with the incisive papilla and mid-palatine raphe can be an important tool for identification of an individual and for evaluating various ethnic populations.
