“…During the biting process, it is the tooth's incisal surface, or cutting edge, that produces the characteristic pattern (32). The analysis of the dental rotations in this study was in fact an analysis of the incisal surface rotations of the individual anterior teeth, thus simulating the analysis of the rotations observed in tooth mark cases.…”

Anterior teeth within the human dentition have a specific numerical rotation value. Bite marks show an array of angled indentations, abrasions, microlacerations, and contusions. These marks generally represent the incisal surfaces of the suspect's dentition reflecting the rotation values of the teeth in the dental arch. This study described a method for capturing and analyzing anterior dental rotations. The rotations of individual anterior teeth within the study population were categorized as common, uncommon, and very uncommon according to Allen's classification. In the absence of a large number of incisal patterns present in a bite mark, a single but heavily weighted tooth rotation could be of equal discriminatory potential to several common rotation values. No prevalence studies quantifying individual tooth rotations are available. The measurement of each individual tooth rotation together with its individual discrimination potential will enhance the evaluation of the concordant features observed in bite marks.

“…Detailed analysis of contusion/abrasion injuries using IR is not found in the English‐speaking literature. Both Gladfelter (1975) and Beckstead (1979) allude to the value of IR in bitemark injuries; but details are not given. Benjamin (1967) made IR recordings of early hemorrhage in hemophiliacs before the lesions were visible.…”

The use of black and white infrared photography for recording blunt force injury

Infrared (IR) wavelengths penetrate skin and can selectively image volumes of subsurface blood. Twenty‐eight blunt force injuries on nine decedents were photographed with color and IR film to compare the ability of each to image the injury. Of the 28 injuries, 10 were clinically interpreted as contusions, 4 as abrasions, 10 as abraded contusions, and 4 as erythematous discolorations, nos. Twenty‐four of these injuries were incised to determine the presence and extent of subsurface bleeding. It was found that contusion had been clinically missed in five cases, three because they were hidden by abrasion and two because they appeared only as a mild cutaneous erythema. All five cases were detected by IR and verified by incision. Melanin pigmentation contributed to masking of contusion in one case and postmortem lividity confounded interpretation of contusion in one case. In all 14 injuries featuring abrasion as a component, IR de‐emphasized or eliminated the visibility of abrasion. A single false negative was reported in which a visible contusion, verified by incision, was not seen with IR. In comparing injury patterns, color and IR renditions were dissimilar in a number of cases reflecting the difference between the manner in which light and IR photography imaged the depth and volume of blood within an injury. In summary, IR imaging of wounds can discover hidden bruises, verify clinical diagnosis of bruises, and augment interpretation of wound patterns. Clin. Anat. 2013. © 2012 Wiley Periodicals, Inc.

Forensic odontology plays a major role in the identification of those individuals who cannot be identified visually or by other means. The unique nature of dental anatomy and placement of custom restorations ensure accuracy when the techniques are correctly employed. It is evident that identification of victims in accidents and natural calamities is of utmost importance and is a challenging task. The teeth may also be used as weapons and under certain circumstances; they may provide information regarding the identity of the biter. Dental professionals play a major role in keeping accurate dental records and providing all necessary information so that legal authorities may recognize malpractices, negligence, fraud child abuse and also, identify an individual. In this article, we will discuss such evolvement of the subject.
