“…Kapli et al [12] and Jain et al [9] reported that rugae growth during palatal development throughout childhood and adolescence only resulted in a change in their length, which becomes constant after adolescence. Therefore, data obtained before adolescence may contain growth-related errors.…”

“…Palatal rugae are highly individualistic with respect to the combined patterns, number, shape, unification, length, width, prominence and orientation [9] and could be used as a personal print [10]. The first scientist that used palatal rugae in identification was Allen in 1889 [11].…”

“…Thomas [4] studied the histologic features of rugae cores from human embryos aged over 20 weeks and found that the reticulin fiber content was miniscule; moreover, the fibroblasts differed from those in adjacent palatal tissues only in size and amount. The palatal rugae can be used to identify a dead body because of their specificity and stability [5]. Moreover, the palatal rugae can be used as an alternative method when individual identification based on fingerprints or dental records is difficult, or when postmortem dental identification is impossible, as in cases with edentulous mouths [6].…”

To determine whether the morphological features of the palatal rugae are associated with sex and age in children and adolescents. Methods: A total of 300 diagnostic models of the palatal rugae of children and adolescents were collected. The models were classified into male and female and<13-and ≥13-year-old groups. The palatal rugae pattern, and the number and length of palatal rugae plicae, were analyzed. Results: The number of palatal rugae plicae was higher in females than in males, however, the difference was negligible. In the group aged 13 years or more, the number was higher in the male group on the left side. There was no association between the number of palatal rugae plicae and age group. The type I pattern was the most common in both males and females. The length of palatal rugae plicae was greater in males than in females. There was no association between the length of palatal rugae plicae and age group. Conclusions: The number and length of palatal rugae were associated with sex, but the morphological features of the palatal rugae could not distinguish between children and adolescents. These findings suggest that the palatal rugae have limited value for identification of individuals.

Background:While there is literature suggesting that the palatal rugae could be used for human identification, most of these studies use two-dimensional (2D) approach.Aim:The aims of this study were to evaluate palatal ruga patterns using three-dimensional (3D) digital models; compare the most clinically relevant digital model conversion techniques for identification of the palatal rugae; develop a protocol for overlay registration; determine changes in palatal ruga individual patterns through time; and investigate the efficiency and accuracy of 3D matching processes between different individuals’ patterns.Material and Methods:Five cross sections in the anteroposterior dimension and four cross sections in the transverse dimension were computed which generated 18 2D variables. In addition, 13 3D variables were defined: The posterior point of incisive papilla (IP), and the most medial and lateral end points of the palatal rugae (R1MR, R1ML, R1LR, R1LL, R2MR, R2ML, R2LR, R2LL, R3MR, R3ML, R3LR, and R3LL). The deviation magnitude for each variable was statistically analyzed in this study. Five different data sets with the same 31 landmarks were evaluated in this study.Results:The results demonstrated that 2D images and linear measurements in the anteroposterior and transverse dimensions were not sufficient for comparing different digital model conversion techniques using the palatal rugae. 3D digital models proved to be a highly effective tool in evaluating different palatal ruga patterns. The 3D landmarks showed no statistically significant mean differences over time or as a result of orthodontic treatment. No statistically significant mean differences were found between different digital model conversion techniques, that is, between OrthoCAD™ and Ortho Insight 3D™, and between Ortho Insight 3D™ and the iTero® scans, when using 12 3D palatal rugae landmarks for comparison.Conclusion:Although 12 palatal 3D landmarks could be used for human identification, certain landmarks were especially important in the matching process and were arranged by strength and importance. Proposed values for 3D palatal landmarks were introduced that could be useful in biometrics and forensic odontology for the verification of human identity.
