Forensic Odontology is the science that correlates dental and legal principles, used for processes such as human identification. One of the possible acting fields for Forensic Odontologists is the analysis and study of patterns and injuries created by human bite marks. This study aimed to show the applicability of dental marks printed in chewing gum for human identification in forensic investigations. A transversal observational study was carried out. The data was collected from 20 volunteers over 18 years old. Each subject had their upper and lower dental casts and was asked to chew a piece of gum for one minute. The pieces of chewing gum were refrigerated at -20ºC for a week, and reproduced with addition and condensation silicones using an adapted reproduction technique. The analysis of the chewing gum was made by overlays. The ANOVA test showed no significant differences on width and length between the pieces of chewing gum and their reproductions (greatest width p=0.918, and the length p=0.981). The analysis of the reproductions with plaster mold showed that there was no difference when using addition silicone or condensation silicone. During the analysis, various suspects could be excluded from the investigation (up to 11, depending on the technique used), but it was not possible to confirm one of them as the main suspect. The study showed that the reproduction technique of chewing gum is efficient, viable and easily performed; and can be used in cases of human identification in forensic investigations. However, it is necessary to certify that the chewing gum effectively presents a bite mark and that it is correctly handled to avoid alterations. It also became evident that the process of refrigeration is essential for the analysis proposed in this study.

Abstract The properties of the skin and the posture of the body during photographic recording are factors that cause distortion in the bite mark injury. This study aimed to explore the degree of distortion between a ‘touch mark’ (method 1) and a ‘bite mark’ (method 2) on the left upper arm at three different positions (arm relaxed; arm flexed in two different positions). A pair of dental casts with biting edges coated in ink was used to create a mark in 30 subjects (6 ♂, 24 ♀) aged 20–50 years old. Photographs were taken using a Nikon DX digital camera (D5000). The mesiodistal widths and angle of rotations of both upper right central incisor and lower right central incisor and the inter-canine distances were analysed and compared with the true measurements using Adobe Photoshop CC 2017. Statistical analysis was carried out using SPSS Statistics 22 applying a 2 (mark type) × 3 (position) repeated measures ANOVA. For all measures studied, there was a statistically significant difference between mark types and positions. In the case of bite marks, a great degree of distortion was detected, and this increased further when changing the position of the arm. The findings demonstrated that skin properties and posture influence distortion. This could lead to inaccurate measurements and misleading pattern interpretation of bite mark injuries.

Introduction: Bite marks are unique to each, differing between one person and another. Several methods to analyse bite mark have been developed during certain periods. However, a standard method to analyse and evaluate the bite mark anatomic variations has not been developed. The objective of this research was to identify the differences of the inter-canine distance on dental cast model, wax impression tracing, radiograph of dental impression tracing, and dental cast tracing methods of the human bite mark. Methods: The subject of the research was as much as 30 consecutive dental cast model, wax impression tracing, radiograph of dental impression tracing, and dental cast tracing for both maxilla and mandible. Measurements performed on each group were conducted in the inter-canine areas using a Vernier calliper. The gold standard that used as a comparator was a dental cast model group on both maxilla and mandible. Comparison of the measurement results was carried out and analysed using a one-way ANOVA test and Tukey LSD test. Results: The average sizes of maxilla and mandible were 37.93 mm and 31.70 mm for dental cast model; 37.93 mm and 32.83 for wax impression tracing; 38.20 mm and 31.70 mm for radiograph dental impression tracing; and 36.65 mm and 30.76 mm of dental cast tracing. The significance value of the maxilla was p = 0.008 (p < 0.05), and the significance value of mandible was p = 0.000 (p < 0.05). Conclusion: The inter-canine distance of radiograph tracing group is found to be most similar with dental cast group as gold standard both in the maxilla and the mandible. Keywords: Bite mark, dental cast, wax impression, radiograph, tracing
