“…Wavy pattern was the predominant rugae observed in our study which were similar in Australian aborigines, Nepalese and Egyptian population. 10,24,26 However the least observed pattern is circular type which is in contrast to the study in Australian aborigines, wherein straight pattern was least observed. 10 Similar observations were also reported in the study on Nepalese and Indian population.…”

“…The numbers of rugae were more in females compared to males, which is in consistency with the study by Gondivkar et al 1 and Kotrashetti et al 21 The observations from our study is not in consistent with other wherein females had fewer rugae and more rugae on right. 9,20,22 In our study primary rugae was most commonly observed however did JCMS Nepal 2017;13(2):241-5 Palatal rugae as an indicator of identification not show any significant differences between the genders which is in consistent to the conclusion drawn by Bajracharya et al 10 in Nepalese population, Kapali et al 23 in Austalian Aborigines and Mahabalesh et al 24 in Indian population. Furthermore Acharya et al 25 from a statistical perspective has showed up to 99.2% in identifying gender on analyzing the shape of the palatal rugae.…”

“…10 Similar observations were also reported in the study on Nepalese and Indian population. 24,27 The second most common pattern was curved which was in consistent to study by Bajracharya et al 24 but in contrast to the findings by Kallianpur et al 28 who reported straight type as second predominant pattern in Nepalese population. The predominant direction of the palatal rugae was forward directed compared to backward which were more in females as consistent with the study by Gondivkar et al 1 Similarly the backward directed pattern were more among females though statistically not significant.…”

Background & Objectives:The cur r ent study was conducted to identify and determine the association between gender and characteristics of palatal rugae in Nepalese population. Materials & Methods: Characteristics of palatal rugae including number, length, shape, direction and unification were analyzed in 100 maxillary dental plaster casts. Association between palatal rugae and gender were tested using chi square analysis and statistical descriptors were identified using SPSS 10.0 keeping the level of statistical significance at p<0.05. Results: A total of 997 rugae were traced. Females were found to have more rugae than males though statistically not significant. In the present study significant difference in secondary (p=0.012), fragmentary (p=0.005), straight (p=0.001) and perpendicular directed (p<0.0001) palatal rugae were observed, which were higher among females. Forward directed followed by backward were predominantly observed and more among females. Wavy followed by curved, straight and circular rugae was the most prevalent shape. Conclusion: No two individual had similar rugae pattern. They can be used to identify people and differentiate between males and females in addition to other tools of identification and has great application in forensic science.

METHODOLOGY: A sample size of 456 individuals aged between 15 and 55 years fulfilling inclusion and exclusion criteria were recruited for the study. The shapes and size of rugae were evaluated on dental casts by classification given by the Kapali et al and Thomas et al respectively. Chi-square test was used to see gender dimorphism in rugae shapes and Mann Whitney U test was used for gender dimorphism in rugae size. A p-value of < 0.05 was considered significant. The equation given by Bharath et al. was used to determine gender of an individual. RESULTS: A significant gender dimorphism in rugae shape among Karachi population was observed. The most common rugae shape in males was found to be wavy followed by straight, curved, convergent, divergent and circular rugae. However, the most common rugae shape among females was found to be curved followed by wavy, straight, divergent, convergent and circular rugae. On observing the size of rugae significant gender dimorphism was reported for secondary rugae (p-value= 0.045). The overall percentage of gender prediction by rugoscopy was 45.6 %. CONCLUSION: Rugoscopy have potential for gender identification and thus may be used for gender identification as an ancillary and supplemental tool in forensic investigation.

Palatal rugae are epithelial ridges on anterior part of palatal mucosa on each side of mid palatine raphe behind incisive papilla. The aim of this study was to compare the uniqueness of rugae pattern amongst sibling pairs, determine the predominant rugae pattern and to assess the gender difference in rugae forms in 5 to 15 years old children and its utility in sex determination. Casts of 50 sibling pairs aged 5 to 15 years were obtained and the rugae pattern was analyzed using Santos's classification. The association of gender with the number of rugae pattern was tested using Chi-square test and unpaired t-test. A significant level of 5% was considered as critical value. All analysis was done using the Statistical Package of Social Sciences 17.0 software (SPSS Inc., Chicago, IL). Rugae were almost uniformly distributed among males and females. The rugae patterns were uniquely structured and there was no evidence of similarity amongst siblings. The most observed form of rugae was curve (30.89%) followed by line (21.07%) and sinous (19.62). Palatal rugae serve as a reference landmark in various dental treatment modalities and can be a valuable tool for personal identification. Rugae pattern may be an additional method of differentiation between the Indian male and female children.
