Dental identification in serial homicides: the Green River murders

Article Abstract:

The body of the first known victim in a series of at least 40 murders was found in the Green River, just south of Seattle, during the summer of 1982. Since that time, 39 more bodies have been discovered in or around the Green River region. Although the Green River murders are still unsolved, much information has been derived through forensic dentistry, and 36 of the victims have been positively identified. Distinctive features and patterns have emerged from these homicides. All of the victims were young women and these crimes have been attributed to a serial killer. Most of these young women had similar lifestyles and were involved in prostitution or drugs and lived a transient existence. Some of the victims were runaways under the age of 18 years old. These and other factors made the positive identification of the victims a difficult task. A short history of famous serial homicides is discussed, along with such well-known characters as Jack the Ripper, Theodore 'Ted' Bundy, and David Berkowitz, the 'Son of Sam' killer. The nature of the serial murder is different from other types of homicide. Serial murders may occur over long periods of time, in a wide variety of locations, and the bodies may not be found until quite some time after the time of death of the victim, which makes the job of identification difficult. The importance of accuracy and clarity in the maintenance of dental records has been stressed for later use in constructing facial restorations, as well as in matching dental structures. The creation of a national standardized format for the maintenance of dental records would be helpful for use in conjunction with existing computerized search techniques. The early involvement of well-trained forensic specialists is also essential in these cases and greatly facilitates the identification process.

Bite marks in forensic dentistry: a review of legal, scientific issues

Article Abstract:

Bite-mark analysis is an imperfect science, although it may yield valuable forensic evidence. Bite-mark evidence was first submitted in a courtroom in 1870. In the ensuing 125 years, forensic investigators have refined bite mark analysis techniques. Bite mark evidence is admissible in a court of law, despite objections about its scientific basis and validity. Bite marks on human victims must be recognized immediately before time distorts the clarity and shape of the mark. The mark should be evaluated, drawn, photographed, described, and swabbed for saliva. Dentists who are familiar with bite-mark analysis are qualified to collect dental impressions and photographs from potential suspects. Bite-mark analysis is affected by the accuracy of bite imprints and the temporary nature of dentition. The uniqueness of people's bites remains subject to question. Analysis and comparative techniques may also influence bite mark analysis.

Antibiotic prophylaxis in dentistry: a review and practice recommendations

Article Abstract:

Most dental patients do not need to take antibiotics before a dental procedure. Antibiotics are sometimes given to patients before a dental procedure because bacteria from the mouth can travel through the bloodstream to the heart. If they infect the heart, the result is a serious condition called endocarditis. Patients most at risk of endocarditis after a dental procedure are those with heart valve disease, congenital heart disease, artificial heart valves, and mitral valve prolapse with a demonstrated heart murmur. Certain dental procedures are also high-risk, including tooth extractions, tooth cleaning, endodontic procedures, and periodontal procedures.
