“…Comparison of 3 D scans of palatal rugae for identification has been suggested [50,51], including for differentiating between monozygotic twins [52]. There are conflicting views as to whether orthodontic treatment changes the morphology of palatal rugae sufficiently to compromise their use for identification [53,54].…”

Forensic odontology frequently plays a significant role in identification of the victims of multi-fatality disasters, but not in all. It depends on adequate dental remains surviving the disaster and on the availability of dental records to be successful. This paper describes current practice in the techniques of identification in forensic odontology and outlines recent advances that are moving into the mainstream. KEY POINTSForensic odontology plays a key role in mass disaster victim identification (DVI) when good-quality antemortem (AM) dental records are available. Images including radiographs, computerized tomography (CT) data and three-dimensional (3D) scan data are considered more reliable AM records than written dental charts and odontograms. Interpretation, transcription and comparison of dental datasets are complex processes that should be undertaken only by trained dental professionals. The future of forensic odontology DVI techniques is likely to include the use of 3D datasets for comparison.

“…Joanna Brigg’s risk of bias assessment: Out of 18 studies, 11 showed a moderate risk of bias [ 8 , 19 , 20 , 22 , 24 , 26 , 27 , 29 , 30 , 31 , 32 ] and 7 showed a low risk of bias [ 16 , 17 , 18 , 21 , 23 , 25 , 28 ] ( Table 2 ). Inclusion criteria have been properly defined by seven studies [ 17 , 18 , 21 , 23 , 25 , 28 , 32 ]. Details of the subjects included in the studies, objectives, and standard criteria used for the measurement and the reliability and validity of the exposure measurement tool have been described by thirteen studies [ 8 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 28 ].…”

Background: To qualitatively and quantitatively review the reliability of palatal rugae as a tool for personal identification following orthodontic treatment. Methods: Cross-sectional retrospective studies assessing the accuracy of matching palatal rugae pattern pre- and post-orthodontic treatment were identified from PubMed and SCOPUS databases. The title and abstract of the articles identified in the search were screened for potential duplicates and relevancy to the topic of interest. The full text of the articles selected in the screening was analyzed using the inclusion and exclusion criteria. Quantitative analysis of the studies representing coherent data in terms of age and treatment choice was performed using RevMan software. Results: Out of 64 screened articles, only 18 articles fulfilled the eligibility criteria and were included in the systematic review. Out of these 18 articles, only 3 studies had data compatible with the quantitative analysis. Significant changes were noted in lateral first rugae in transverse bilateral direction (p = 0.02) and between second and third lateral rugae of the left side in the anteroposterior direction (p = 0.04). Despite the dimensional changes, observers in most studies were able to accurately (>90%) match the palatal rugae pre- and post-orthodontic treatment through visual observation. Conclusion: The accuracy of the visual matching, despite the significant dimensional changes, indicates that morphology could have potentially been the major matching factor. Thus, a combination of dimensional and morphological evaluation of the palatal rugae could potentially increase the accuracy of personal identification.

“…Compared with other relatively mature identification techniques (such as DNA), palatal rugae identity is still in the initial stage of study (Li et al, 2014;Wu et al, 2016). Scholars have focused on the description of the palatal rugae pattern and the coding of the rugaes (Bharath et al, 2011;Mittal et al, 2013;Braga & Caldas, 2016). There are few ideal preprocessing and evaluation schemes about the palatal rugae images, and a more complete preprocessing system has not been established.…”

Palatal rugae is an irregular soft tissue, which is located in the front third of the hard palate, and is asymmetrically distributed from the middle suture to the sides. The difference, stability and extensive characteristics of palatal rugae morphology have gradually make it a characteristic indicator of forensic identification. However, a mature digital palatal rugae identification system has not yet been established at present. Feature extraction is the premise of palatal rugae image recognition. In order to obtain palatal rugae feature information in all directions and improve the reliability of forensic identification, it is necessary to collect palatal rugae images from a plurality of different angles. When the collected images are sent to the recognition system, the diversity of angles will often cause problems such as error recognition. If the tilted images are not rotated properly, it will make the forensic identification face many difficulties. To solve the problem of image skew caused by the diversity of acquisition angle, an algorithm based on orientation vector to correct the tilted palatal rugae images was proposed in this paper. Firstly, the criteria for standard palatal rugae image and the selection rules for feature points were set; Secondly, characterizing feature points according to the rules, and fitting two lines and find their direction vector; Finally, to obtain the corrected images, the tilted images were rotated by the angle determined by the two direction vectors. Simulation results show that the proposed algorithm can correct the tilted palatal rugae images collected from different angles and has strong robustness.
