AbstractBackground: Palatal-Rugae refer to the ridges on either side of the median palatal raphe & on the anterior part of the palatal mucosa, behind the incisive papilla. Numerous studies on various individuals have identified definiterugal trends within each group.
Aim: The different patterns of Palatal-Rugae among the individuals of Central India are studied, evaluated & documented & compared with the patterns described in the literature that can assist as an additional method of identification in cases of crime or mass disasters.
Material & Methods: Pre-orthodontic casts of 200 samples (100 males & 100 females) have been selected. The method for defining the pattern of rugae used was Thomas et al. The different types of rugae among males & females have been analyzed statistically in the literature & compared with other studies.
Results: A statistically insignificant (p >0.05) higher mean primary rugae score was observed in males (7.32 ± 2.78) while higher secondary (3.72 ± 2.24) & tertiary (2.88 ± 1.36) rugae score were observed in females. Both genders displayed predominance in the wavy shape of distribution (males= 4.76 ± 1.64 & females= 4.18 ± 1.56). Commonly observed trends converged (58%) in males & diverged patterns (62%) among females in the unification mode, which was statistically significant (p= 0.04).
Conclusions: The findings showed a clear rugal pattern in this group, relative to other individuals reported in the literature. Palatal-Rugalpatterns are definitely associated with geographic variation & may act as an additional tool for assisting in forensic identification procedures.
