DESCRIPTION
Bite mark analysis has traditionally been used in forensic science as a tool for suspect identification, particularly in violent crime investigations. However, its scientific credibility has come under increasing scrutiny in recent years. Several factors contribute to the unreliability of bite mark evidence, including the distortion of skin during and after biting, variations in human dentition, and significant observer bias during analysis. These variables can lead to inconsistencies and misinterpretations, raising concerns about the objectivity and admissibility of such evidence in court. This study critically reviews the foundational issues surrounding bite mark analysis and explores both traditional and modern approaches used in forensic odontology. Traditional methods rely heavily on two-dimensional imaging and manual comparison, which are prone to error and subjectivity. In contrast, advancements in digital technologies such as 3D scanning, computer-assisted overlays, and artificial intelligence offer the potential for more accurate and reproducible assessments. Despite these technological improvements, there is still a lack of standardized protocols and scientific validation, limiting their current forensic application. The study highlights that while bite marks may serve as supportive evidence, they should not be used in isolation to determine guilt or innocence. A multidisciplinary approach that includes DNA analysis and other corroborative forensic techniques is essential. In conclusion, the role of bite mark analysis in forensic investigations remains controversial. Caution must be exercised in its application, and ongoing research, technological development, and methodological standardization are needed to enhance its reliability and ensure justice in forensic practice.
CONCLUSION
In conclusion, bite mark analysis remains a highly debated area within forensic science. While it has historically played a notable role in suspect identification, especially in cases involving violent crimes, the reliability and objectivity of bite mark evidence continue to be questioned. Key issues such as skin elasticity, post-mortem changes, and individual variability in dental anatomy contribute to the challenges of accurate identification. Moreover, human factors like observer bias and subjective interpretation can significantly impact outcomes, raising concerns about the validity of bite mark evidence in legal proceedings. Traditional methods of bite mark comparison, often reliant on 2D photographic analysis and visual matching, have shown limitations in terms of reproducibility and accuracy. Recent advances in digital technology including 3D imaging, computer-assisted overlays, and machine learning algorithms offer promising tools that could improve precision and reduce bias. However, these technologies are still under development and require rigorous validation before they can be fully relied upon in forensic practice. This study underscores that while bite mark evidence can serve as a useful supplementary tool in forensic investigations, it should never be used as the sole basis for conviction. A multidisciplinary approach that includes DNA analysis, witness testimony, and other physical evidence remains essential for ensuring justice. Looking ahead, further research and standardization are critical to improving bite mark analysis. Establishing objective, scientifically sound protocols and integrating emerging digital methods could enhance the credibility of this technique. Until such advancements are fully realized and accepted by the broader forensic community, caution must guide its application in legal contexts. Ultimately, the future of bite mark analysis lies in balancing its potential utility with scientific rigor. Only through ongoing evaluation, transparency, and technological refinement can bite mark identification evolve into a more reliable and ethically sound component of forensic odontology[1-13].
