Abstract

Age estimation is one of the important components in forensic science used for personal identification, biological profile reconstruction, and help narrowing the search possibilities. Age estimation can be done by various methods and biological evidence, such as the human face. The human face is one of biometrics that provides a variety of information.  The purpose of this article is to evaluate the accuracy and reliability of age estimation with face using smartphone for forensic identification based on previous studies and experiences. Age estimation by face is based on age progression that causes attrition and degeneration on soft tissue. With the development of technology, age estimation by face can be done with applications or websites on smartphone. In general, the utilization of smartphone can reduce waste, pollution, research cost and easier to save and share. A lot of applications have been developed and free to download. Unfortunately, the accuracy of its results is unknown. In conclusion, the applications for age estimation on smartphone give quiet good results and can be used as a supporting tool to estimate age in forensic identification.

Abstract

Background: Decades ago, documentation of forensics evidences such as bitemarks, bloodstains and others which required sophisticated photographic techniques and equipments such as infrared (IR) and ultraviolet (UV) photography, became a problem since they only use film that must be developed. Therefore, direct evaluation of the photographic result could not be directly visualized. The equipments prices were relatively high. Moreover, most of the equipments were still not available and relatively expensive; and converted IR digital camera could not use for regular photography. Recently, digital camera made image documentation and editing easier. Purpose: This review was aimed to explore the different characteristics and benefits of regular digital camera in IR forensic photography as well as to simplify the equipments needed. Reviews: IR photography becomes easier since certain digital cameras could capture the IR image by using IR filters or to be switched to IR camera. The regular non-SLR digital camera had certain advantages compared to SLRs, such in focusing. However, since not every digital camera has the ability to capture IR light, laser pointer or TV remote could be used as a tester. Conclusion: Knowledge about IR Bite mark photography, characteristics of regular digital camera and its accesories could reduce the budget for an ideal standard forensic photographic equipments by modifications.Latar belakang: Puluhan tahun silam, dokumentasi bukti forensik seperti teraan gigit, bercak darah dan sebagainya yang memerlukan teknik dan peralatan yang canggih seperti fotografi infra merah (IR) dan ultraviolet (UV) merupakan masalah karena memakai film yang harus diproses terlebih dahulu untuk mengetahui hasilnya. Akibatnya, hasil pemotretan tidak bisa langsung dievaluasi, selain itu harganya relatif mahal, kamera digital yang diubah menjadi kamera IR tidak bisa untuk pemotretan biasa. Saat ini kamera digital dan program komputer mempermudah dokumentasi dan penyuntingan. Tujuan: Tujuan dari tulisan ini adalah untuk menjabarkan sifat dan keuntungan kamera digital dalam fotografi IR forensik dan menyederhanakan peralatan yang dibutuhkan. Tinjauan pustaka: Fotografi IR dipermudah karena kamera digital tertentu dapat menangkap gambar IR dengan menggunakan filter IR atau diubah menjadi kamera digital IR. Kamera biasa non-SLR mempunyai beberapa keuntungan dibandingkan SLR antara lain dalam memfokuskan obyek. Walaupun demikian, karena tidak semua kamera digital biasa dapat menangkap sinar IR, dapat dilakukan pengujian dengan penunjuk laser atau pengatur jarak jauh televisi. Kesimpulan: Pengetahuan tentang fotografi IR, kamera digital biasa dan peralatan tambahannya dapat mengurangi biaya peralatan fotografi IR standar forensik dengan cara modifikasi.

Abstract

Background: Tooth eruption, the movement of teeth toward the oral cavity clinically marked by the emergence of the cusp or incisal edge, is very important in determining the chronological age of a child. Unfortunately, tooth eruption in 6-12-year olds on the island of Madura has yet to be investigated. Purpose: This study aimed to analyze differences in permanent tooth eruption between boys and girls aged 6 to 12 years old on Madura. Methods: This study employed an observational analytic design in combination with a cross-sectional approach. The samples used in this study were selected by means of simple random sampling technique. Post-selection informed consent of the child subjects was obtained with their chronological age being assessed and determined prior to tooth eruption. The normality of the data was subsequently analyzed by application of a one sample non-parametric Kolmogorov Smirnov test. Thereafter, repeated Anova tests were conducted to determine differences in the permanent tooth eruption of the subjects. Results: Based on the normality test results, the significance value of the permanent maxillary teeth in the male subjects was 0.993, while that of their permanent mandibular teeth was 0.695. In contrast, the significance value of the permanent maxillary teeth in the female subjects was 0.970, while that of their permanent mandibular teeth was 0.918. According to the results of the repeated measure ANOVA test, differences existed in the eruption of the permanent maxillary and mandibular teeth between the males and females with a significance value (ρ) of 0.020. The mean value of permanent mandibular tooth eruption in the females was 56.59 ± SD 33.403, while that of their permanent maxillary tooth eruption was 50.77 ± SD 34.201. The mean value of the permanent mandibular tooth eruption in the males was 55.31 ± 33.024, while that of their permanent maxillary tooth eruption was 48.77 ± SD 34.201. Conclusion: On Madura, the permanent teeth of chronological 6-12-year old females, particularly their permanent mandibular canine teeth, erupt earlier than those of their male counterparts.

Abstract

Background: Forensic dentistry identification commonly involves using dental cast models as ante-mortem data. Here, dentists generally send the pictures as well as the dental records. However, in recent times, dentists – especially orthodontists and prosthodontists – are using 3D scanners in view of reducing the space for cast model storage as well as sending the 3D imaging for fabricating clear aligners and other items such as crowns and bridges. This new trend means data transmission and viewing has become more complicated since sophisticated laptops or personal computers are generally required. For more practical use, smartphones would be a better option, meaning various simple ideas for viewing 3D data must be explored. Furthermore, the conclusions must be evaluated in terms of the validity for forensic dentistry use. Purpose: To evaluate a number of smartphone applications that are simple, user friendly, scalable and capable of the measurement and superimposition of 3D imaging data. Review: Standard tessellation language (STL) is one of the 3D scan file formats that is also useful for 3D printing. Recently, several applications for 3D viewing have been made available for iPhones (iOS) and Android-based devices, which are able to view STL files. However, they have all received both positive and negative reviews in terms of various applications, including forensic dentistry, and they thus require further evaluation by forensic odontologists. Conclusion: Each application has advantages and disadvantages; however, in our experience as forensic odontologists, the CAD Assistant, exocad and Adobe Photoshop Mix, which are available for iOS and Android devices, are preferable for forensic dentistry needs

Abstract

Lip prints and bloodstains may be left behind in many crime scenes and may reveal the identity of the victimand the suspected person. This study was aimed to investigate the inheritance pattern of lip prints and bloodgroups among parents and their offspring in the Javanese population. 105 subjects from 25 Javanese familyframes participated in this study. Lips print pattern was recorded and analyzed according to Suzuki andTsuchihashi classification. A blood group test was also performed for each subject. The statistical analysiscarried out using IBM® SPSS® Statistics version 23.0 (IBM, Armonk, New York, USA). The results of thisstudy revealed that type II was the predominant pattern of lip prints among the Javanese population (34.3%).Blood group A was the predominant type in subjects with lip prints type II (15%). The result also shows thatthe lip prints pattern in girls tends to be inherited from the mother. However, the inheritance of lip printspattern in boys couldn’t be determined precisely. The heritability of lip prints pattern was observed betweenparents and their offspring. Also, there was a tendency of blood groups to have a certain pattern of lip prints.

Abstract

Background: In forensic medicine and medicolegal, sex determination is an important step of an identification process. Parts of human skeleton that can be used for identification are cranium, pelvis, and mandible. There are several anthropometry tools in sex determination methods i.e shape of mandible, mental, gonial angle. Gonial angle in adults is an excellent tool for sex determination. However, bone density and masticatory force may change the value of gonial angle. Purpose: The objective of this study was to examine sex determination method using gonial angle in children during grow spurt period and external factors. Methods: There were 104 randomly selected subjects (51 boys and 53 girls) aged 7-12 years old. The subjects were grouped into prolonged sun exposure-hard diet (group A) and low sun exposure-soft diet (group B). The measurements were made using goniometer. Results: The mean of gonial angle of female children was greater than the male children. There was no significant difference between group A and B. Conclusion: Gonial angle can be used for sex determination in grow spurt period, and external factors did not affect sexual dimorphism.
