Subjective and Quantifiable Analysis of Palatal Rugae Pattern in Punjab Population

Abstract


 Background: - Palatal Rugae are irregular, asymmetric ridges of mucous membrane extending laterally from incisive papillae and anterior part of palatal raphe. Palatal rugae patterns are relatively unique to individuals and are well protected by lips, buccal pad of fat and teeth.
 Aims & Objectives: - The aim of the study was to identify pattern of palatal rugae in terms of number, size, and shape and also to compare rugae patterns in males and females of Punjab population.
 Materials & Methods: - A total of 280 maxillary casts that were randomly collected and were examined using graphite pencil and magnifying glass under adequate light with equal number of males & females. Statistical analysis was done by T-test using SPSS software version 20.
 Results: - The mean rugae were found to be more in females than males. Most prevalent form on basis of shape is found to be straight and on basis of size is primary form. Statistically, significant values were found in curved and secondary type, both more in females than males.
 Conclusion: - Palatal rugae pattern is definitely a sufficient characteristic to discriminate between the genders. The present study highlighted the prevalence of palatal rugae in individuals of Punjab population. It is unique to an individual and can be used successfully in identification.
