“…[8] When palatal rugae have anomalies and abnormalities, there are considered as reflection of abnormal growth those could be the source of forensic identification. [1] Concerning the gender, in this study, the total number of rugae was slightly fewer in females than in males, but statically not significant, this result agrees with Saraf et al, [9] Fahmi et al, [10] and Kapali et al [4] As a shape of rugae, in this study, the total of wavy and curveshaped rugae was the most common representing 70.63% of the total samples of the present study and these results agree with previous studies done by Venegas et al [11] and Indira et al [12] The most common type is the wavy shaped and this result agrees with Jawad [13] and disagrees with Indira et al [12] that they found the most common is the curve, and this may be due to the different regional or race samples.…”

Background: It is a well-known fact that teeth are considered crucial in identification; in edentulous cases, palatal rugae are handy in individual identification. There are evidences proved that there are gender related and geographic variation in palatal rugae pattern. Hence, the purpose of this study was to figure out the role of palatal rugae in differentiation between sexes of Saudi Arabian population. Materials and Methods: A total of 50 maxillary dental stone cast were prepared comprised both male and female samples of same age group, casts were looked for rugae shape such as straight, wavy, curved, unification, and circular and their percentage recorded. Results: The average number of rugae patterns in both sexes in total and the mean values that show no significant differences between both sexes although the number of rugae was slightly higher in male than females in total. Conclusion: This work concludes that rugae patterns can be used as additional method for identification as a personal print and considered a characteristic to discriminate between individuals.

“…This identification of rugae depends on several factors such as presence or absence of tooth, palatal height changes caused by degenerating alveolar bone after tooth loss, poorly delineated rugae eminences, indistinct outline or form of alveolar arches, and more complex patterns (line, curve, circle, bifurcated, sinnous) or non-complex patterns (line only) in some cases [14] . In the present study significant differences were observed between the mean values of both the groups and also on the distribution of the rugae pattern between both the groups similar to studies by Jawad IA [8] , Kapali et al [15] , Bhatt.G [16] . Among completely edentulous individuals (group A) Sinnous pattern (2.1±1.65) is more common followed by line (1.4 ± 1.39); curve (1.4 ± 1.48) and bifurcated type (0.6 ± 0.81) whereas in partially edentulous individuals (group B) Line pattern (2.6 ± 1.71) is more common followed by sinnous (2.2 ± 1.74); circle (0.6 ± 0.78) and bifurcated type (0.3 ± 0.61) based on number and distribution.…”

“…Rugae pattern, well protected by lips, cheek, tongue, buccal pad of fat and teeth in certain conditions such as burnt bodies in incident of fire or higher temperatures or where bodies have decomposed severely and encountered high impact trauma can be an effective personal identification tool [7] . Preservation of rugae plays an important role in prosthetic rehabilitation especially among completely edentulous individuals as it acts as the stress bearing area that prevents displacement of the denture anteriorly [8] , guides in setting the maxillary teeth at the anterior region and provides indirect retention in denture extension cases [9] . Nevertheless rugae pattern are least susceptible to external environment changes and are unique to every individual often considered as a consistent relevant marker of forensic importance [10] .…”

Background: Preservation of palatal rugae plays an important role in prosthetic rehabilitation and in forensic identification when the individual has no teeth either completely or partially owing to its resistance and stability. However recent studies have shown substantial rugae pattern changes are caused by tooth loss of prolonged duration. Aim: The present study was carried to compare and evaluate the effect of tooth loss on rugae pattern among completely and partially edentulous maxillary arch individuals as a reliable personal identification tool. Methodology: A total of 50 participants were divided into two groups comprising of 25 completely edentulous (Group A) and 25 partially edentulous (Group B) individuals. Impressions, maxillary casts were made and the number, type of rugae patterns were recorded using graphite pencil and tracing paper every 3 month over a period of 1year based on Martins dos Santos classification system. Results: More complex patterns (line, curve, circle, bifurcated, sinnous) are observed in Group B with significant differences between the mean values of line, bifurcated and circle pattern when compared to Group A. Simultaneously mean differences in sinnous pattern (Group A) and Sinnous, Line pattern (Group B) within the group were also seen over a period of 1 year. Conclusion:The present study thus showed significant differences in the rugae pattern between both the groups and greater changes with complex patterns were observed in partially edentulous group when compared with the complete edentulous group.

Background:Analysis of palatal rugae patterns, which are similar to fingerprints, is one of the techniques used in forensic sciences for human identification. As palatal rugae patterns are genetically determined, they can also be used in population differentiation and gender determination. Hence, we aimed to record the distribution of the predominant rugae pattern in Kerala population.Materials and Methods:A total of 100 maxillary study models (40 males and 60 females) recorded from Kerala population within the age group of 17-25 years were analyzed. The dental casts were examined for the interpretation of the total number, length, shape, location and unification of rugae. Chi-square test and unpaired t-test were employed for statistical analysis.Result:The total number of rugae was significantly (P < 0.001) greater in females than males. Regarding the shape, wavy pattern predominated in both males and females, followed by curve, straight, divergent, convergent and circular pattern. Circular pattern was more in males than females. The rugae patterns were located more in between mesial aspect of first premolar to mesial aspect of second premolar.Conclusion:The palatal rugae and their features of an individual may be considered as a reliable guide for identification purpose, provided antemortem casts are available. Nevertheless, gender differentiation is evident in terms of number and shape of rugae.
