Evidence-Based Forensic Dentistry by Balwant Rai download in iPad, ePub, pdf
Other factors include poor photography, impressions, or measurement of dentition characteristics. Currently, dental impressions collected as evidence are compared only to those collected from a given suspect, which may bias the resulting outcome. Most of the controversies facing bite mark analysis are due to the lack of empirical supporting evidence.
Bite marks can be altered through stretching, movement, or change in environment after the bite. They also used plaster of paris as the substrate to simulate skin, yet the two materials have very different properties. Also, bite marks can be altered through stretching, movement or a changing environment during and after the actual bite.
Then Krone was later reconvicted and given life in prison. She is Editor in Chief of one and Deputy Editor of two journals.
Bite marks may be found on the flesh of victims of a violent attack, particularly on the stomach or buttocks. The lack of research may largely be due to the fact that such studies are difficult to organize and are very expensive. Alternatively they may be found on the suspect, left by the victim during self-defense. The use of transparent overlays is considered subjective and irreproducible because the tracing can be easily manipulated.
This book presents basic concepts in the field and describes all the standard examination procedures currently employed in the acquisition of dental evidence. Kouble and Craig compared direct methods and indirect methods of bite mark analysis. For example, braces apply force to specific teeth, in order to shift the placement of multiple teeth. One possible issue facing bite mark analysis is a lack of bite mark uniqueness in any given population. Limitations to the bite mark studies include differences in properties of pigskin compared to human skin and the technique of using simulated pressures to create bite marks.
Transparent overlays are made by free-hand tracing the occlusal surfaces of a dental model onto an acetate sheet. Furthermore, the level of distortion tends to increase after the bite mark was made. Therefore, bite marks found at the scene are often analyzed under the assumption that they have undergone minimal distortion. The authors believe that a simplified version would increase the strength of the comparison process.
This disagreement resulted from the fact that even though the two suspects had dental features making them unique, the bite mark itself was not detailed enough to reflect them. In the case of Mississippi vs.
Rai has extensive experience in curricular development and is an Expert Jury member for the National Research Foundation, South Africa. He is examiner of different universities. He is the Editor in Chief of four journals and serves as a reviewer for a number of scientific journals. This brings into question whether or not there is enough scientific support for bite mark analysis to be employed in court. Studies have been performed in an attempt to find the simplest, most efficient, and most reliable way of analyzing bite marks.
