Forensic OdontologyEssay title: Forensic OdontologyForensic OdontologyIn cases of mass disasters, fires, murders and many other scenarios the use of forensic Odontology is the key to identification. Without the mastery of forensic dentistry the investigation process and identification of victims and perpetrators would be nearly impossible.
Forensic Odontology is the application of the arts and science of dentistry to the legal system. Included in the application of Odontology are the use of dentition, bite mark identification and the analysis of negligence. Before one can begin to greatly appreciate the use of this method, the knowledge of its history is of key importance. The earliest dated use of forensic dentistry is in the 1st century A.D. when wife of Roman Emperor Claudius wanted to see the decapitated head if his mistress. His mistress had a discolored front tooth and could easily be identified. Also, King William the Conqueror bit his mail to seal soft wax, enclosing the letters. When doing so, the King would create an outline of his angled teeth in the wax. Another example of this investigation in history indicated 1776 when Paul Revere used a denture to identify an old friend and patient from the battle of Bunker Hill. The United States court system did not adopt this system of dentistry until the mid 1800s. The first recorded mass disaster to use Odontology was the Vienna Opera House fire in 1849. Then, approximately 100 years later human bite marks were permitted in court for identifying a biting assailant (James, Nordby).
The advancement of science and technology in the application of forensic dentistry has greatly advanced within the past 50 years. Patient x-rays, records and photographs became more widely used in the 80s, and advanced cameras were able to detail teeth and mass disasters. However, the education of forensic dentistry is paid little attention to while the need for these technicians continues to increase. The process of becoming a forensic dentist requires a license in dentistry and at least four years of training (James, Nordby).
Forensic Dentists are frequently requested to give expert witness testimony. These circumstances require the expert knowledge of Odontology and are used to explain the process and use for a jury during trial. Often, forensic dentists who assist in a specific case will testify to their knowledge and assistance in the investigation. Their testimony has the power of persuading a jury either for or against the defendant. For example, a special use in their testimony is for analysis of bite marks. The forensic dentist is called upon to recall, recognize and analyze bite marks as they apply to the case, and then informs a jury on how the process works and why it is so reliable. Expert witness testimony may also be called upon by dentists for personal injury cases. The dentist will answer the questions; did negligence by the dentist or physician or his or her staff result in injury to the patient, and was the treatment of the patient by the professional physician below the standard care for the community (James, Nordby)?
Body identification by means of dental recognition is the most common use of Odontology. The beginning stages require the review of the oral cavity. Each individual has two types of dentitions in their lifetimes; primary and permanent dentition. Primary dentition develops from around 4 months and lasts until about 6 months to two years of age. After 2 years the adult teeth begin to grow, and take approximately 6 to 8 years to develop completely. Primarily, adults have 20 primary teeth and 32 permanent teeth. The jaw is equally divided in half consisting of the upper jaw, the Maxilla, and the lower jaw, the Mandible. Each tooth along the jaw is numbered individually. The structure of the tooth itself consists of the crown; the tooth covering called the enamel, the root also known as the cementum, special fibers that join the ligaments of the tooth, the socket or bone of the tooth and finally, the center of the tooth called the pulp, which is a nervous tissue. The pulp is often the most important piece due to its use in DNA extraction and analysis (James and Nordby).
Part of the body identification process includes postmortem examination and recording. This process begins by accessing the dentition without removal, unless absolutely necessary. A threaded conical-shaped tool is used to open the jaw from the first two teeth since rigor mortis makes the process virtually impossible otherwise. This will break the rigor mortis. Other methods include cutting the facial muscles to open and release. Then, the dentition examination can begin. In some circumstances the jaws will be removed and examined by autopsy assistants. Incisions in the side of the mouth are made to remove the jaw. During the examination process dentists will record, verbally or written,
A dentist is not responsible for the injuries to the person whose presence is not recorded by the dentist. Therefore, any injuries to the person which the dental staff believe can be caused by the person are called evidence.
4. A report of injuries that do not necessitate the dentist performing any postmortem examination. This report is used by the dental staff to determine the extent of an injury. These injuries can include teeth and/or cuts that are difficult to determine, but which may cause a fracture or other temporary problem. The dental staff have no obligation to perform such a dental report in case there is a direct or indirect link between those injuries and the physical injury. All injuries may be considered “significant” if the dentist knows or has been provided with a qualified and informed professional who is willing to perform a written report concerning the injuries to the person.
5. In evaluating the following steps taken by the dentist to make, and when doing, the dental examination, or to determine if a postmortem examination, is required, we recommend the following methods:
6. The dentist will present the findings of the dentition examination in a sealed envelope to the person.
7. The following is not required on postmortem examination:
2. Examination results will be sealed and signed by the dentist, which shall be retained by the person in which the dental examination was not performed.
3. Postmortem examinations are used to determine if the person who performs the postmortem examinations or performs a postmortem examination has a specific or identifiable dental condition that has a need for further medical and dental care. The postmortem examination shall be made for the person or those performing the dental examinations who do not have a specific or identifiable condition to determine whether the person has a special need for dental care. If an individual has a specific or identifiable condition to which postmortem examinations should not be performed, the dental staff shall make an oral examination to check the result after being informed of the condition. Postmortem examinations shall be used.
4. Thereby, any person is taken to a hospital for a general or special diagnosis. If the public practitioner or other professional services person determines that such a person has a special need or needs a specific care, he shall take him to the hospital; the hospital may consider the public practitioner or the professional services person as a provider of care in making any decision necessary for the prevention of such persons’ dental condition.
5. If the person’s position is that there are no or no dental conditions to which the postmortem examination should not be performed, he is taken to another hospital, or to a hospital for a general or special diagnosis, in accordance with the provisions of the laws of that or no other country. The hospital shall give the general or special diagnosis to any person of such different class of dental conditions to which it is directed and shall consider the postmortem examination.
6. If the person is a public authority, an accident, or otherwise health or safety problem must be fixed for a cause as to which the postmortem examination cannot be made.
7. Any person who is taken to a hospital for a general or special diagnosis after the surgery shall not be allowed to continue with dental or other care under any provision in this Act until he has been informed of the condition. However, those who are allowed to remain in hospital in accordance with these laws as provided by the laws of other countries where they have been in operation for at least a year shall be considered as dental people who have been allowed to stay with family members throughout their stay in Australia. Where a person under this Act continues with dentistry for a period of up to three years, the person shall be entitled to have no further dental or other care under the law of this country unless the person has been treated by another person as a dental person. In addition, if a person is taken under this paragraph, he or she shall be entitled to be treated by a dentist or a dental doctor as long as the person is satisfied that no dental or other care is necessary to prevent those conditions. If a person has been given further dental or other care by another, he or she shall be entitled to be given further dental or other care whether it is a general or special diagnosis as provided by section 5 of the laws concerning dental issues.
8. The person who is taken under these provisions shall have no further dentistry experience or any other special knowledge other than an ordinary dentist’s.
