Cremation in Interwar Romania: The Case of the Potter's Field.

This article aims to analyse the activities of Potter's Field practice in Romania as part of the Patriarch Miron Orthodox Association. From its very beginning it was orientated against the apparition of cremation in Romania, realized in the first cremation at the Cenușa Crematorium in Bucharest (1928). The target was to 'save' poor people from cremation, considering that the cremation aimed to remove from the local authorities the pressure of supporting the costs of burials for unidentified bodies and bodies that were unclaimed by families ('the social cremations'). Therefore, the Potter's Field practice developed in Romania in an original way in comparison to other countries. This situation indicated a way of translating cremation into reality in Romania and expressed some of its particularities in this country (the implication of the authorities, cremation as a personal choice or the forms of criticism by the religious environments).

Molecular age prediction using skull bone samples from individuals with and without signs of decomposition: a multivariate approach combining analysis of posttranslational protein modifications and DNA methylation.

The prediction of the chronological age of a deceased individual at time of death can provide important information in case of unidentified bodies. The methodological possibilities in these cases depend on the availability of tissues, whereby bones are preserved for a long time due to their mineralization under normal environmental conditions. Age-dependent changes in DNA methylation (DNAm) as well as the accumulation of pentosidine (Pen) and D-aspartic acid (D-Asp) could be useful molecular markers for age prediction. A combination of such molecular clocks into one age prediction model seems favorable to minimize inter- and intra-individual variation. We therefore developed (I) age prediction models based on the three molecular clocks, (II) examined the improvement of age prediction by combination, and (III) investigated if samples with signs of decomposition can also be examined using these three molecular clocks. Skull bone from deceased individuals was collected to obtain a training dataset (n = 86), and two independent test sets (without signs of decomposition: n = 44, with signs of decomposition: n = 48). DNAm of 6 CpG sites in ELOVL2, KLF14, PDE4C, RPA2, TRIM59 and ZYG11A was analyzed using massive parallel sequencing (MPS). The D-Asp and Pen contents were analyzed by high performance liquid chromatography (HPLC). Age prediction models based on ridge regression were developed resulting in mean absolute errors (MAEs)/root mean square errors (RMSE) of 5.5years /6.6 years (DNAm), 7.7 years /9.3 years (Pen) and 11.7 years /14.6 years (D-Asp) in the test set. Unsurprisingly, a general lower accuracy for the DNAm, D-Asp, and Pen models was observed in samples from decomposed bodies (MAE: 7.4-11.8 years, RMSE: 10.4-15.4 years). This reduced accuracy could be caused by multiple factors with different impact on each molecular clock. To acknowledge general changes due to decomposition, a pilot model for a possible age prediction based on the decomposed samples as training set improved the accuracy evaluated by leave-one-out-cross validation (MAE: 6.6-12 years, RMSE: 8.1-15.9 years). The combination of all three molecular age clocks did reveal comparable MAE and RMSE results to the pure analysis of the DNA methylation for the test set without signs of decomposition. However, an improvement by the combination of all three clocks was possible for the decomposed samples, reducing especially the deviation in case of outliers in samples with very high decomposition and low DNA content. The results demonstrate the general potential in a combined analysis of different molecular clocks in specific cases.

Sex estimation from skull measurements of a contemporary Japanese population using three-dimensional computed tomography images.

In this study, we assessed the sexual dimorphism of the contemporary Japanese skull and established sex discriminant function equations based on cranial measurements using three-dimensional (3D) computed tomography (CT) images. The CT images of 263 corpses (142 males, 121 females) that underwent postmortem CT scanning and subsequent forensic autopsy were evaluated. Twenty-one cranial measurements were obtained from 3D CT reconstructed images, which extracted only bone data. We performed descriptive statistics and discriminant function analyses for the measurements. Nineteen measurements were significantly larger in males, suggesting sexual dimorphism of the Japanese skulls. Univariate discriminant function analyses using these measurements showed a sex classification accuracy of 57.8-88.2%, and bizygomatic breadth provided the highest correct prediction rate. Multivariate discriminant function analyses offered the most accurate model using seven variables with an estimation rate of 93.9%. Our results suggest that cranial measurements based on 3D CT images may help in the sex estimation of unidentified bodies in a contemporary Japanese population.

Who are they? A retrospective study of unidentified bodies in Institute of Medical-Legal Paris from 2018 to 2023.

Despite great advances in human identification, unidentified decedents remain a global problem.This 6-year overview study covering a total of 2 324 unidentified bodies admitted to the IMLP provided relevant information about the unidentified decedent population and assessed the impact of a protocol established in 2017 on the rate of deceased buried without identity in Paris.The need to establish a national database in France to properly document and disseminate information on missing persons and to centralize the biological profile of unidentified bodies is key, as without antemortem information or a biometric database there can be no matching.

Tato sebagai Metode Identifikasi Korban Meninggal Tanpa Identitas

The identification of individuals is a critically important aspect of the forensic examination process, as errorsin the identification process can have fatal consequences in the legal proceedings. The identification of a living patientcan be carried out through various methods, including fingerprint identification, visual recognition, documentation,accessories, dental records, serological examinations, and biomolecular analysis. Presented is a case study of a maleindividual who died as a result of a motor vehicle accident involving a bus, which resulted in head and chest trauma,leading to the victim's immediate demise at the scene. No identifying marks were found on the victim, but the victimhad a tattoo on the left chest. Identification and external examinations were conducted by a team of doctors andINAFIS personnel, synchronized with the information provided by the victim's family. Subsequently, an analysis wasperformed, correlating with a review of the literature based on scientific publications. The final result was thesuccessful identification of the deceased individual, thus concluding that tattoos can be used as one of the methods ofidentification for individuals or unidentified bodies, supported by other methods such as family data and other uniqueindividual characteristics. However, the use of tattoos needs to be handled with caution due to the risk of infection,allergies, or the transmission of infections through poorly executed and unclean tattoo procedures.

Организация информационно-аналитического обеспечения оперативно-розыскной деятельности органов внутренних дел по розыску лиц, пропавших без вести, в условиях контртеррористической операции и вооруженных конфликтов

The planning and implementation of operational search activities play a pivotal role in the search for missing persons amidst counter-terrorist operations and armed conflicts. Key to these efforts is the utilization of data that can aid in the identification or recognition of the missing individual. Such data includes physical descriptions in the form of verbal portraits or photographic impressions, basic identifying information, fingerprint cards, and handwriting samples. These pieces of information serve to individualize the sought-after person and can be instrumental in their identification. The establishment of new databases of operational search information, including databases of genomic codes of individuals, could prove to be a valuable tool in obtaining information about unidentified bodies and linking them to missing persons. However, the implementation of such databases raises a number of technical, legal, and ethical issues that must be considered. This article aims to examine the specifics of organizing information and analytical support for the operational activities of internal affairs bodies in the search for missing persons in conditions of counter-terrorist operations and armed conflicts, utilizing available resources accessible to operatives. In conclusion, the effective organization of information and analytical support is paramount in facilitating the search for missing persons within the challenging contexts of counter-terrorist operations and armed conflicts. Leveraging various data sources, including physical descriptions and emerging technologies like genomic databases, offers promising avenues for enhancing identification processes. However, the integration of such resources necessitates careful navigation of technical, legal, and ethical considerations. By addressing these complexities, internal affairs bodies can optimize their operational efforts and contribute significantly to resolving cases of missing individuals amidst complex security environments.

Investigation of a DNA Profiling Method Using Only Cementum More Than 70 Years After Death.

Short tandem repeat (STR) typing is widely used not only for blood relationship identification but also for the personal identification of unidentified bodies. However, DNA is susceptible to the effects of environmental factors, consequently leading to reduced DNA yields. Therefore, to maximize the DNA yield required for identification, teeth are generally completely pulverized during DNA extraction. However, this renders subsequent testing after DNA profiling impossible. In this study, we investigated the utility of DNA profiling using only the cementum from teeth that had been left outdoors for long postmortem intervals. We analyzed 90 molars (fresh teeth) that were extracted within six months at a dental clinic and 90 molars (stale teeth) exposed outdoors for over 70 years, and following cementum extraction, the accuracy of STR profiling, optimal site for cementum collection, and minimum amount of cementum required for STR profiling were determined. The results demonstrated that the profiling accuracy of DNA extracted from cementum was comparable to that of DNA from dental pulp and dentin. Furthermore, the collection of cementum from either near the cervical line or from the root apex areas did not show significant differences in DNA profiling accuracy, indicating that securing at least 5 mg of cementum was sufficient to ensure precise DNA profiling. These findings suggest that DNA profiling using only cementum is viable even in teeth that have been subjected to a long postmortem interval.

Pattern of injuries in Two-Wheeler riders involved in Road Traffic Occurrence –an Autopsy Study

Background: Road traffic injuries are India’s sixth leading cause of death, affecting youth and middle-aged individuals. Rapid motorized traffic growth, particularly two-wheelers (72% of vehicles), has increased accidents. Inadequate and non-uniform helmet regulations worsen the situation. Road injuries strain healthcare, demanding hospitalization, and rehabilitation. Kerala experiences significant two-wheeler accidents, often fatal due to head injuries. Studying injury patterns and causes among riders in fatal accidents is vital. Methods: A cross-sectional study was conducted at Govt TD Medical College, Vandanam, Kerala, following approval from the Institutional Ethics Committee. The study included all deaths of two-wheeler riders involved in road traffic accidents with clear vehicle information, excluding decomposed or unidentified bodies. A total of 101 cases were analyzed, recording external and internal injuries directly onto the Proforma during autopsy. Data were summarized using frequencies and proportions, while the chi-square test assessed relationships between categorical variables. Conclusion:The study found that most accidents occurred between 6-9 pm, involving mainly male (91.1%) two-wheeler riders (80.8%). Few wore helmets (5%). Head injuries (97%) were common, often caused by ejection from vehicles (87%). Non-helmet use and ejection related significantly to head injuries, a leading cause of twowheeler accident fatalities

Height Assessment Using the Length of Humerus of Selected Group of Hausa Ethnic Students in Yusuf Maitama Sule University, Kano State

Height assessment from bones plays a vital role in detecting unidentified bodies and parts of bodies or skeletal remnants, the aim of this study was to estimate the height of individual using the length of humerus of selected group of Hausa ethnic Students in Yusuf Maitama Sule University, Kano State, Nigeria. Two hundred and two (202) subjects were selected from the various faculties of the University, using random sampling method. The age range of the participants was between 18-50 years. Ethical approval was required from the Ethical Committee of the College of Health Science of the institution before the beginning of the research, Informed consents were sought from the participants. Using a stadiometer, standing height of individual was measured to the nearest centimeter (cm) with subject standing barefoot in an anatomical position. The humeral length was measured in between two points:- Distal point-Midpoint of elbow joint and Proximal point- Acromian landmarks, line was measured and documented. Length of humerus obtained was put in regression equation for humerus estimation. From the result obtained indicated that height can be estimated from the humeral length with Coefficient of significance (R=0.628) Coefficient of determinant (R2=0.395). The present study found significant differences between the sex in both humeral length and height of the study population and resolved that the maximum height can be estimated from the length of humerus with effective precision so that may help the archaeological, anthropometric and also forensic investigations.

Extended Review of Political Choreographies, Decolonial Theories, Trans Bodies

This article offers a comprehensive review of Political Choreographies, Decolonial Theo-ries, Trans Bodies, the latest book, a volume edited by Marina Gržinić and Jovita Pristovšek in intensive collaboration with Nomusa Makhubu and Tjaša Kancler, published by Cambridge Scholars Publishing in 2023. This volume takes as its starting point the body as a structural signifier, which is conceptualized in seven chapters. Each of them addresses the question of movement, politics, revolt, action, etc., in a variety of ways to de-link ourselves (especially us Whites) from colonial modernity as the organizing principle not only of capitalism but of a whole range of processes that emanate from modernity, i.e., forms of domination and oppression such as racism, sexism, Eurocentrism, and environmental destruction. What makes this book special, however, is not only the positions presented but also the way in which they are presented. Each conversation begins with a carefully selected starting point, linked to the interlocutor’s* work and accompanied by a rich citation system of references and additional information. This opens up the formation of epistemic counter-narratives that confront the violent history of capitalism and form possibilities for yet unidentified bodies, movements, politics, and political action as future potentialities.

The evidential value of dental calculus in the identification process

DNA analysis-based identification is by far the gold standard in forensic genetics and it should be performed in every case involving human remains or unidentified bodies. Bones and teeth are the preferred source of human DNA for genetic analysis. However, there are cases where the nature of the proceedings and historical significance prevent the disruption of skeletal structure. The remains may also be heavily degraded. In such situations, forensic geneticists seek alternative sources of human DNA. Teeth calculus has proven to be a viable source of DNA for identification purposes. The aim of this study was to assess the concentration of human DNA in teeth calculus and evaluate the usefulness of teeth calculus as a DNA source in the identification process. Teeth calculus was collected from skeletons exhumed between 2021 and 2022 by the PBGOT (Polish Genetic Database of Victims of Totalitarianism) team from the former Stalag IID prisoner-of-war camp in Stargard. Genetic analyses included the determination of autosomal and Y-STR markers. The total concentration of human DNA was also evaluated in samples from teeth calculus and teeth taken from the same individuals. The pilot study included 22 skeletons with a sufficient amount of calculus for isolation (specified in the protocol). Samples were taken from the largest areas of calculus deposited on lingual surfaces of mandibular incisors. The prepared samples underwent DNA extraction. Our study demonstrated that teeth calculus is a source of human DNA for remains from the World War II period. The obtained DNA concentration allowed for the determination of STR markers. It was shown that teeth calculus contains human DNA in an amount suitable for preliminary identification analyses.

The accuracy of topographical and shape analysis using three-dimensional surface scanning compared to Micro-Computed Tomography

The high number of unidentified bodies recorded in South Africa annually, combined with substantial heterogeneity within the population, necessitates that innovative forensic analysis methods be developed that incorporate variations from South African groups. Although sizeable three-dimensional (3D) scanning modalities exist in osteology and anthropology, developing new advanced methods and techniques involving 3D scanning for real-life forensic applications require that the accessibility, practicality, and, more importantly, accuracy of the methods be taken into consideration. To this end, this study aimed to assess the reliability of 3D surface scanning-based topographical and shape analysis comparison to gold standard micro-focus X-ray computed tomography (micro-XCT) reconstructions for estimating population affinity. Forty-four adult crania were collected from the Pretoria Bone Collection (PBC), University of Pretoria, South Africa. Two sets of 3D reconstructions were acquired from each cranium, namely micro-XCT scans and 3D surface scans. Three-dimensional reconstructions and landmark datasets were acquired from both scanning modalities and compared using reproducibility testing, geometric discrepancies, and shape analysis. The minimal geometric discrepancies observed between the reconstructions suggest that both modalities will provide similar shape landmarks datasets and can be used without compromising the accuracy of the analyses at term. The statistical findings showed similar population affinity-related mid-facial shape variations analyzed across both modalities using geometric morphometric methods (GMM). Incorporating multiple 3D scanning modalities and advanced GMM into the existing biological profile estimation will allow South African forensic anthropologists to analyze shape-related skeletal variation in a more accurate and repeatable way and provide an efficient biological profile in forensic cases.

Management of unidentified and unclaimed bodies: a comparison of model from four countries in the Asia Pacific Region.

Managing mass fatality incidents or disasters involving multiple deaths are not uncommon among forensic practitioners. In fact, management of unidentified or unknown bodies is also a vital component of the day-to-day mortuary work practice. The unidentified and subsequently unclaimed bodies have always been a "silent mass disaster," a problem that needs to be tackled within the forensic community and raises the global issue of ethics, law, and human rights. Unidentified bodies' in Malaysia make up an average of 4.02% of all death cases where a total postmortem examination was performed which is comparable with other developing countries within 4-10% which can go up to 25%. Moreover, unstandardized procedures in all mortuaries in different states and districts in Malaysia have worsened the scenario even with guidelines in place. This study aims to address the issues surrounding unidentified and unclaimed bodies including body disposal from a social and legal perspective using case study methodology by comparing four different countries in the Asia Pacific Region through document analysis and interview methods. One of the major findings is evident in 3 out of the 4 models, whereby there is a considerable gap in consolidating the missing person report and information to match with the unidentified bodies received in forensic institutions in an attempt to enhance the identification process which ultimately intends as a closure for the family members. It is also timely to think out of the box beyond dental records and DNA profiling to improve the identification rate for skeletonized remains through means of anthropology biometrics comparison. With the limited literature published surrounding this domain, it is hoped that the suggestions and recommendations to standardize the management of unidentified and unclaimed bodies can benefit many forensic institutions and public mortuaries in this region.

Knowledge, Awareness, and Interest in Forensic Odontology Among the Dental Teaching Staffs in the Dental Colleges of Jharkhand.

Forensic dentistry is a subspecialty of forensic science that handles, examines, and presents evidence from teeth in the most ethical manner possible. In addition to doing research, forensic odontology (FO) entails managing, examining, assessing, and presenting evidence from dentistry in civil or criminal investigations. In these circumstances, the forensic odontologist aids the court system by reviewing the dental findings. The present investigation was carried out to assess the dental faculty member's awareness, interest, and knowledge of FO at dental educational institutions in Jharkhand, India. The sample size calculation assumes a simple random sampling technique and a large population size using the formula E=sqrt((Z^2*p*(1-p))/n).A total of 102 dental teachingfaculty members from diverse dental specialties participated in the survey. Utilizing a validated questionnaire that was sent directly after receiving approval from the institutional ethics committee in January 2023, data were gathered in a tailored manner. The questionnaireincluded 12 questions to gauge the dental teachingfaculty members' awareness, knowledge, and interest in FO. Closed-ended questions were included. The outcomes were computed using a percentage system. In this study, 95% of study participants agreed with the fact that teeth are a possible source of DNA, while 5% were unaware of this fact. 68% of study participants said that visual examination constitutes the initial stage in the identification process for unidentified bodies while 8% of study participants said that DNA fingerprinting constitutes the initial stage in the identification process for unidentified bodies. However, 8% of study participants didn't know anything about this aspect. 72% of dental teaching faculty members agreed to the fact that Barr bodies should be used to determine sex. 89% of study participants responded positively to the question"Can teeth or enamel serve as a tool for determining age?" 11% of study participants did not know that teeth or enamel can serve as a tool for determining age. 41% of study participants had the correct information that FO instruction for bachelor of dental surgery (BDS) students takes place and, as per Dental Council of India (DCI) standards, should be given in both BDS second and third years. The results of the current survey provided information on FO practices among Jharkhand dental institutes' dental faculty. The poll revealed that they have the necessary information, which they must have learned either while studying, participating in continuing dental education, or teaching.

Facial Soft Tissue Thickness Values for Romanian Adult Population

Introduction: Forensic identification practice requires a multitude of methods for positive identification, among which the facial reconstruction occupies a high place. For this to be done in the best way possible, it is mandatory that each population have their own database regarding soft tissue thickness. Objective: The present research is focused on creating such a database for the Romanian adult population and on exploring the statistical distribution and correlation of craniometric landmarks, overall, and in groups defined according to sex and weight categories. This might provide support in estimating the values of missing landmarks or other variables (e.g., age, sex) for unidentified bodies. Methods: Twelve craniometric landmarks were measured on 100 cadavers less than 24 h after death. Results and discussions: Of the 12 anatomical landmarks, only one appears to manifest statistically significant differences between sexes, and seven landmarks appear to vary significantly among the weight categories. Additionally, some evidence of interpopulation differences in the average soft tissue thicknesses were observed by the comparison of these data with similar studies from Caucasian groups with different geographic origin. Additionally, correlations between facial landmarks were examined, overall and between sexes.

Estimation of age from digital chest radiographs in district Mandi, Himachal Pradesh

In forensic investigations estimation of age is a crucial part. Age estimation assists in narrow downing the search possibilities in the case of unidentified bodies and living individuals, it can also help in the determination of preparators and deciding the penalty for any criminal liability. Different body parts are often investigated at the crime scene, so estimating the age using different areas of the body is important. Hence, we conducted this study for age estimation from costal cartilage calcification. Only posterior-anterior (PA) digital chest radiographs are taken, and the first rib of the left side is evaluated. The degree of calcification and age showed a positive correlation; similarly, the value of Spearman’s rho showed significant results (for the whole sample =0.914, p < 0.01 (for male subjects was =0.925, p < 0.01. For females was =0.905, p < 0.01). The degree of calcification is useful in estimating age groups and becomes more determined with advancing age. Prediction of age using the radiological method gives the advantages of ease, inexpensiveness, rapidity, and high accuracy. In developing countries, this type of study will be very useful because infrastructure and lack of sources are major issues. The article provides a non-destructive method of age estimation in a forensic context that may act as a preliminary method of age estimation in mass disasters and dismembered bodies when a thoracic cage is only present.

Unburials and Skeletal Reconstructions: Narrative as Forensics in Michael Ondaatje's Anil's Ghost

Social scientists know how crucial it is to identify the bodies of the men, women and children who have died at sea or on land, or have been buried in mass burial grounds, and how consequential it is to engage (or not) in some form of ritual, of memorialization. If some scholars have focused on locating and numbering those victims, others have used forensic science to identify the bodies so that the families can get them back, engage in mourning and continue to live. Others, still, interrogate the lost objects of the death-bound migration. This essay will focus on a novel that deals with the exhumation and identification of bones in a civil war context. In Michael Ondaatje's Anil's Ghost, Sri Lankan-born and North American-educated Anil Tissera goes back to Sri Lanka as a forensic anthropologist. She is sent by a human rights group to investigate mass burials during the Civil War and genocide of the Sri Lankan Tamils, thus returning from her diasporic abode after 15 years. In Anil's forensic search for identification, with bones being literally unearthed, what does the literary text perform for those lost or unidentified bodies that could not be accomplished otherwise? What kind of engagement does it offer? Using the angle of forensics and its Latin etymology, this essay will formulate the hypothesis that the literary text enables justice to be delivered in an open court of law (forensis). Moving beyond the stigmatization of the unritual, it will probe the fraught relationship between literature and forensics, investigating the possibility that the narrative, its staging of the unidentified body of the dead, and our relationship to it, could create a public space to be shared by all (forum).

Comparative Study of Two Methods of DNA Extraction from Dental Pieces

Colombia is a country with an internal armed conflict of more than 60 years, where forensic sciences claim a vital role in strengthening transitional justice within the framework of the peace process. Just look at the statistics of unidentified bodies, to realize how far behind the identification process is in Colombia; where according to Life application: There are some 26,660 to 35476 unidentified bodies that, despite the joint efforts of agencies such as the Missing Persons Search Unit, Forensic Medicine and the Attorney General’s Office, have not yet been handed over to their relatives. For this reason, it is necessary to recognize the massive task of forensic specialists to propose new methods that optimize the identification process. Responding to this call, the IdentiGEN Laboratory compared two methods of extracting DNA from teeth, the ChargeSwitch Forensic DNA Purification Kit (Invitrogen) and the QIAamp DNA Mini Kit (Qiagen) to determine which of the two allowed optimization, not only the time of analysis but the costs of application with respect to the conventional method used for these matrices. To do this, DNA extraction was performed with each kit and subsequently extracts were quantified by fluorometry, demonstrating that although both methods are highly efficient in time and cost; the QIAamp method DNA Mini Kit (Qiagen) has a higher yield in terms of the amount of genetic material obtained. Finally, the dental parts analyzed using the PowerPlex Fusion System (Promega) commercial kit were successfully typified, showing not only that these matrices present a viable source of DNA collection but that it is possible to continue improving extraction methods so that they are increasingly simple, economical and effective.

Current Issues in Dental Identification in Severely Burned Bodies from a Studio Arson Attack in Japan

A studio arson attack in Japan caused 36 deaths. Dentists obtained dental findings from 33 unidentified bodies immediately after the attack and autopsy. The dental findings before autopsy were obtained on the day of the incident and the next day. Dental findings after autopsy were obtained at 1 week from the day after the incident. We examined issues associated with collecting these dental findings. Other findings recorded were CT images, autopsy findings, and various blood and pathological examinations. Among the 33 unidentified bodies, for 30 bodies, the number of teeth from which the dental findings were obtained was significantly higher after autopsy than before autopsy. The dental findings of the remaining three bodies were not obtained before or after the autopsy. Five percent of anterior teeth and 28.7% of molars had differing pre-autopsy and post-autopsy findings. This discrepancy can be attributed to various factors. One of the major influencing factors was the carbonization of the facial surface muscles and skin along with limited mouth opening due to thermocoagulation. For the scientific identification of an individual based on dental findings, it is mandatory to examine the teeth in all quadrants. The collection of dental findings solely from anterior teeth may not be adequate to establish identity. The present article describes the challenges faced by the dentists while identifying charred bodies in an arson attack.

Automatic identification of individuals using deep learning method on panoramic radiographs

The dentition shows individual characteristics and dental structures are stable with respect to postmortem decomposition, allowing the dentition to be used as an effective tool in forensic dentistry. We developed an automatic identification system using panoramic radiographs (PRs) with a deep learning method. In total, 4966PRs from 1663 individuals with various changes in image characteristics due to various dental treatments were collected. In total, 3303 images were included in the data set used for model training. Vgg16, Vgg19, ResNet50, ResNet101, and EfficientNet models were applied for identification. The precision curves were evaluated. The matching precision rates of all models (Vgg16, Vgg19, ResNet50, ResNet101, and EfficientNet) were examined. Vgg16 was the best model, with a precision of around 80-90% on 200 epochs, using the Top-N metrics concept with 5-15 candidate labels. The model can successfully identify the individual even with low quantities of dental features in 5-10s. This identification system with PRs using a deep learning method appears useful. This identification system could prove useful not only for unidentified bodies, but also for unidentified wandering elderly people. This project will be beneficial for police departments and government offices and support disaster responses.
