“…11 Observing the length of rugae, it appears that primary rugaes are most prevalent than secondary and fragmented rugaes. 12 Examining the types and origins of palatal rugae according to the Lysell classiications, the study of Beatrice's (2013) showed that the palatal rugae of males is diferent from that of females. Primary and Secondary rugaes are all found in males compared to females, whereas fragmented rugaes are more common in females than males.…”

Background: This paper discusses palatal rugae patterns and their contribution in the identiication of individuals and the determination of family lineage in West Sumatera, Indonesia. Identifying an individual is a prerequisite for the issuance of death certiicate as well as for personal, social and legal reasons. The most common techniques used in this context are dental records, ingerprint and DNA comparisons. However, under certain circumstances, these cannot always be used. But interestingly, palatal rugae patterns are preservable because they are impervious to disasters and hostile conditions and can be used as alternative human identiication techniques. This paper argues that the study of palatal rugae (rugoscopy) cannot only help to reveal a person's identity but also to determine their family lineage. Objective: The present study was carried out to ascertain whether there is any hereditary patterns in the palatal rugae patterns of the mother, father, and the ofpring in one family. Method: This is a cross sectional study of 48 samples consisting of 12 families in Luhak Nan Tigo. The parents and ofspring (son or daughter) of each family were randomly selected. Palatal rugae impression was recorded using alginate while palatal rugae patterns were noted and recorded. One Way ANOVA test (SPSS 17) was used as statistical anaysis method. Result : The study shows that there is a signiicant similarity in curved, wavy, and straight rugae patterns (p> 0.05) as well as in primary, secondary, and fragmented rugae based on the family tie between the father, mother, sons and daughters of the Minangkabau ethnic. Unilateral and circular rugae tests are insigniicant (p <0.05). Conclussion : This is a cross sectional study whose results are only based on 48 samples consisting of 12 families, therefore further studies are needed with a larger sample quantity. The results of this study indicate the role of factors in the patterns of palatal rugae.

“…The morphology and position of the palatal rugae hardly change after diseases, trauma or chemical corrosion. Genetic, unique and stable human palatal rugae patterns contribute to forensic identification (Shetty et al, 2015;Thabitha et al, 2015).…”

To analyze the accuracy rate of a digital image recognition system in matching the palatal rugae Morphology after orthodontic treatment, before orthodontic treatment and to provide theoretical evidence for individual identification in the field of forensic dentistry. High-resolution digital images of the palatal rugae were taken under particular conditions from each patient before and after orthodontic treatment. Features of each digital image were extracted using a digital image recognition system and included in the palatal rugae database. Using an MATLAB software system, information matching of the palatal rugae was performed. From the matching results, the accuracy rate of individual identification of orthodontic patients was 100 %, with a Euclidean distance of 0. The accuracy rate in matching palatal rugae patterns before and after orthodontic treatment was 95.67 %. The results were statistically significant with P < 0.05. Palatal rugae pattern is highly individual-specific. After orthodontic treatment, palatal rugae are morphologically diverse, but these changes do not greatly influence the individual identification in the field of forensic dentistry, which provides a new method of and pathway to forensic identification.

“…From the point of view of forensic medicine, palatal rugae patterns contribute to forensic identification (Santos et al, 2011Rath & Reginald, 2014Poojya et al, 2015;Thabitha et al, 2015). There are controversies about whether diverse morphological changes of palatal rugae patterns after clinical orthodontic treatment can influence forensic identification.…”

LI, B.; TAE-GEON, K.; WU, X. ; HEE-MOON, K. ; KE-MING, Y. & XIU-PING, W.Model analysis of anatomical morphology changes of palatal rugae before and after orthodontic treatment. Int. J. Morphol., 35(4):1224Morphol., 35(4): -1229Morphol., 35(4): , 2017. SUMMARY:Model analysis was performed to identify palatal rugae anatomical morphology patterns, evaluate their individual-specific properties and stability before and after orthodontic treatments, and investigate their reliability in the use for individual identification from the perspective of forensic dentistry. Maxillary models of 70 patients were collected before and after orthodontic treatments, palatine images were taken under standard conditions. Pattern-based individual identification was performed through measuring some indices including changes in number, orientation, shape, and length of palatal rugae, as well as mesial and distal endpoint displacement of palatal rugae in the anteroposterior (AP) and mesiodistal (MD) direction. At the same time, maxillary models of 10 patients were randomly selected for individuality confirmation and the average rate of correct matches was calculated. palatal rugae anatomical morphology patterns were highly individual-specific. Palatine of the same pattern were not found before or after orthodontic treatment. Model-based analysis confirmed the high individual-specificity properties of the palatal rugae anatomical morphology patterns, and also showed that the incidence of any morphological change in the patterns after orthodontic treatment was 45.7 % for anteroposterior displacement of the distal endpoint of palatal rugae, 40 % for mesiodistal displacement of the distal endpoint of palatine, 32.9 % for anteroposterior displacement of the mesial endpoint of palatal rugae, and 17.1 % for mesiodistal displacement of the mesial endpoint of palatal rugae. The incidence of change in length, orientation and shape of palatine after orthodontic treatment was 28.6 %, 1.4 % and 1.4 % respectively; and the incidence of palatal segmentation and unification after orthodontic treatment was 4.3 % and 2.9 % respectively. The mean percentage of correct matches of the palatine patterns after orthodontic treatment to their duplicates was 99.05 % and the mean percentage of correct matches of the palatine patterns between before and after orthodontic treatment was 92.19 %. Palatal rugae anatomical morphology patterns are unique to each individual. After orthodontic treatment, palatal rugae have diverse presentation patterns. Although the diverse palatine patterns to a certain degree, influence individual identification in the field of forensic identification, palatal rugae patterns can be used as a novel method for individual identification in forensic dentistry.
