Forensic odontology is a discipline within forensic science that involves the management, examination, evaluation and presentation of dental evidence in criminal or civil proceedings (1). The main goal of forensic dentists/odontologists is to identify humans (1, 3). Forensic dentists have many methods that are used for dental identification. Some of these methods include bite mark analysis, labeling of dental prosthesis (dentures), rugoscopy (palatal rugae which are located on the roof of the mouth), and cheiloscopy (lip prints) (1). This paper will focus on the process that forensic dentists take to identify humans using teeth, how forensic dentists conduct bite mark comparisons, the methods/techniques that are used to do these comparisons and why forensic odontology is an important discipline in forensic science. The references cited throughout this paper were chosen as they were informative and clear. The majority of the articles cited contained multiple photos that made the information a lot easier to follow. Forensic dentists have played a major role in the identification of remains in mass disasters, in crime investigations, in ethnic studies, and in the identification of decomposed and disfigured bodies in situations such as fire and car accidents (1). Teeth are considered to be a great form for identification as teeth are mostly composed of enamel. Enamel is the hardest tissue in the body and can withstand extremely harsh conditions (1). Two forms of dental identification of humans exist. These two forms are comparative and when no ante-mortem (before death) dental records are available. The comparative form of identification compares the ante-mortem and post-mortem (after death) dental records (1). Dental records con... ... middle of paper ... ...ot be found, the forensic dentists uses a post-mortem dental profiling to aide in narrowing down the search (3). Bite marks are quite common in forensic odontology. The American Board of Forensic Odontology has broken up bite mark analysis into 3 major stages. These stages are a description of bite marks, the collection of evidence from the victim and the suspect and finally, the analysis of the bite marks (5). The methods used to perform this task are the manual process which using tracing, photocopier generated overlays, 2D polyline method and the painting method (4). Despite having better and more improved methods to conduct the comparison of bite marks, there still exists a huge problem. The problem involves the physical properties of skin which may cause the bite mark to change (5). Hopefully, in the future more research is done to overcome this issue.
285) These types of injuries usually come from knives, axes, or other weapons like that. In some instances, a sharp trauma will look like a line across the bone. So, if someone is not trained in knowing what these marks are, they can be easily over looked. According to Byers (2011) “sharp trauma is the result of narrowly focused, dynamic compression forces applied to the surface of a bone.” (p. 285) Unlike blunt or projectile trauma, sharp force will be focused in a single area, unless the suspect us using an ax or machete there won’t be a large amount destruction to the bones. Using an ax or machete however can severely damage the bones that can look like blunt trauma. So, it is important for the forensic anthropologist to be able to distinguish between them.
What once seemed like a typical accident of an eight-year-old girl on her bike, seems to be a cover up story for what is suspected to be child abuse. With a review of the patients complete dental record history, it
The pertinent facts of this case are as follows: On February 24, 1986, Sheri Rasmussen was found dead in her home, having suffered three fatal gunshots to her chest. There were signs that Rasmussen had struggled with her assailant, as she had multiple contusions and what appeared to be a bite mark on her left inner forearm. The pathologist that examined Rasmussen’s body determined that the bite mark had
The blood of the unknown person became apparent through comparing the blood type found at the crime scene with the contrasting blood types of the suspects. The blood identified at the crime scene could have possibly belonged to Anna Garcia or Erica Piedmont. This observation was based on the information that the blood type found at the crime scene was type A and these two individuals are the only ones that carry that specific type. In similarity, a microscopic photography was taken of the unknown hair follicle found at the crime scene. Then hair samples were taken from the potential suspects, and the victim. These findings were then compared. This was done by looking at each individuals hair follicles and comparing it with the unknown one. By looking at the similarities and differences in medulla diameter, the discovery of the unknown hair follicle became established that it belonged to Anna Garcia. Further examination resulted in the analyzation of a shoe print found at the crime scene. Shoe patterns and sizes were taken from each suspect, including the victims. They were then identified and compared to the one found at the crime scene. By looking at the distinct pattern, size, and the fact that both shoes were a Columbia brand sneaker it became obvious that the shoe print was extremely similar to Anna’s shoe design. Through this found evidence it became
Dentistry as a profession over the years has evolved rapidly in light of new scientific evidence. Rapidly evolving science and technology have implemented changes within dentistry as evidenced by new standards and guidelines being produced by nationally recognised associations including National Institute for Health and Clinical Excellence (NICE), Faculty of General Dental Practice (FGDP) and Scottish Intercollegiate Guidelines Network (SIGN) in Scotland, in provision of new scientific evidence. The latest standards and guidelines produced, endorse everyday clinical practice through evidence based dentistry (REF). All dental professionals as part of continued professional development are expected to keep to date on relevant guidelines and knowledge related to their practice (REF). This is supported by the General Dental Council who state all clinicians must maintain their professional knowledge and competence throughout their working career (REF).
When someone says forensic anthropology, many minds go directly to beautiful woman working alongside good-looking men while they work to solve a murder in a day’s time, thanks to the media craze with homicide. The recently popular television show Bones, put the field of anthropology in the spotlight. Though the show gives fairly accurate information, many viewers, myself included, have developed a great curiosity for how the work is done. In this paper, I will share with you the answers to many of the questions I have asked myself in my many hours of watching this popular show, including: the process of identifying race, age and sex of a victim, determining whether an injury was antemortem, perimortem or postmortem, and how one is able to interpret the injuries in the case of the death.
On Wednesday, November 16, 2011, Katherine Stang, Aresh Kabirnavaei, and Andrew Roller, all students in the Master’s of Forensic Science program gave thesis presentations to the Forensic Seminar Class. The following paragraphs will summarize each topic.
Forensic psychology is a continually adapting sphere. It is hard to have one solid definition for the field, as there are so many aspects that interlock. Within each attribute of the forensic psychology has roles and responsibilities to sustain. The rapid growth and emerging importance of this field volumes of information will be developed in the next decade.
Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a la...
Healthcare is a necessity to sustain society. Dentistry is an area of healthcare that I feel extremely passionate about because access to proper dental care is limited, especially in the underserved communities. As an African American, I want to become a dentist and healthcare provider in the hopes of helping patients and adding to the diversification of the field. With a growing minority population in the United States, it has become apparent that there is a shortage of black dentists. This is problematic because underrepresented minorities are in great need of access to culturally connected dentists who understand their clinical needs as much as their lives and their challenges. I believe that when the profession includes a range of ethnicities
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Forensic odontology is becoming a more ubiquitous method of human identification following gruesome deaths, disasters, and crimes. Usually, the first step in forensic odontology is the comparison of antemortem (before death) dental records and postmortem (after death) dental records (Source 1). Antemortem dental records are useful to match the victim with the cadaver; for instance, if a known person is missing and a body is found, forensic odontologists are able to examine the dental status of the cadaver and analyze any possible correlations to the dental conditions of the victim before death. Victims will not always have clear, accessible dental profiles. In that case, analysis begins with the observations of the cadaver to make identity deductions, enabling specialists to choose the information that best fits the characteristics of the deceased individual (Source 1). This method is called comparative identification. During the comparison process, the ultimate goal is to note
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene
Radiography plays an integral role in today’s forensic society. “Forensic investigations can help identify victims of a mass casualty event, lead to development of improved technology to prevent future deaths or serve as the difference between acquittal and conviction in a court of law.” Forensic radiography, in short, is the use of radiographic techniques accompanying legal usage of such images. Since its discovery in 1895, forensic radiography has advanced into other scientific regions, such as x-ray fluorescence spectrometry (XRF), skeletal scintigraphy (nuclear bone scan), virtopsy (virtual autopsy), multidetector computed tomography (MDCT), and neuroimaging, thus attributing to a large number of ante and post-mortem cases. Forensic radiography plays a pivotal role in archeology, paleontology, art forgery, and drug smuggling (body packers). Proper training and impeccable knowledge is imperative for a successful radiograph to be admissible as evidence in a civil or criminal court proceeding.
