“…Daniel and Pazhani [16] proved that the bitemark pattern was more accurately analyzed in chocolate and cheese than in apples. Kanaparthi et al [17] also conducted a bitemark analysis on food and found that the use of food medium for bitemark study has several susceptibilities due to the shrinkage of food, food decomposition, and the influence of temperature.…”

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.

“…3D technology opens up new possibilities for the field of forensic odontology, one of which is the use of intraoral scanners to scan bitemarks and create 3D permanent evidence. 5,9,11 Although the use of an intraoral scanner is extremely beneficial, it necessitates specialized equipment that is costly and frequently unavailable on-site. This raises the question of whether there are any other economic methods available with the same 3D model producing effectivity, one of which is smartphone utilization.…”

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
