Bitemark analysis is a challenging procedure in the field of criminal case investigation. The unique characteristics of dentition are used to find the best match between the existing patterned injury and the suspected perpetrator in bitemark identification. Bitemark analysis accuracy can be influenced by various factors, including biting pressure, tooth morphology, skin elasticity, dental cast duplication, timing, and image quality. This review article discusses the potential of a smartphone camera as an alternative method for 3D bitemark analysis. Bitemark evidence on human skin and food should be immediately recorded or duplicated to retrieve long-lasting proof, allowing for a sufficient examination period. Various studies utilizing twodimensional (2D) and three-dimensional (3D) technologies have been developed to obtain an adequate bitemark analysis. 3D imaging technology provides accurate and precise analysis. However, the currently available method using an intraoral scanner (IOS) requires high-cost specialized equipment and a well-trained operator. The numerous advantages of monoscopic photogrammetry may lead to a novel method of 3D bitemark analysis in forensic odontology. Smartphone cameras and monoscopic photogrammetry methodology could lead to a novel method of 3D bitemark analysis with an efficient cost and readily available equipment.
Bitemarks are patterned injuries caused by teeth in conjunction with other oral structures that are used as evidence in forensic investigations. Its characteristics vary from person to person, even in identical twins. By matching the existing bitemark with the suspect's bitemark, the unique dentition of each individual becomes the scientific basis for identifying bitemarks. Because bitemark proof on human skin and food is transient, it should be immediately recorded or duplicated to retrieve lasting proof, allowing for a longer time of examination, which 3D bitemark analysis can do. However, the currently available method with an intraoral scanner (IOS) necessitates the purchase of expensive specialized equipment that may not be readily available everywhere. The use of a smartphone camera on a monoscopic photogrammetry method could lead to a novel method of 3D bitemark
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
