Forensic identification (ID) based on an assessment of the dentition is commonplace. However, despite an increase in the oral health of Western populations, there are still many millions of individuals who are edentulous and whom have been treated with completed dentures. In the United Kingdom alone over 300,000 patients are rendered edentulous each year. In order to facilitate the ID of such individuals a number of forensic and governmental organizations have recommended that dentures be labeled. A number of labeling systems exist which can be broadly separated into inclusion systems, marking systems, and novel methods. Each of the commonly described systems are demonstrated with an assessment of their strengths and weaknesses. It is recommended that an inclusion denture marker, preferably metallic, should be used in order to withstand the most common postmortem assaults.
Dental forensic organizations world wide have recommended that dental prostheses should be labeled with at least the patient's (wearer's) name and preferably with further unique identifiers such as social security number. A range of methods are available and the purpose of this study was to determine, via the means of a visual questionnaire, which are the most preferable to those patients who wear complete dentures. One hundred edentulous patients attending the Manchester Dental Hospital were shown a range of denture labeling methods and asked to rank these according to their preference. The most preferred method was that of an embedded radio frequency identification microchip (38% rated this as first) and the second was an inclusion technique using onion paper (24% rated this as first). The least preferred method was the use of a groove cut into the denture flange with 71% of patients rating this as the poorest in terms of esthetics. The study demonstrates that the method of denture labeling is important to patients and to ensure that denture labeling is performed routinely esthetic preferences must be considered.
This paper looks at how carefully prescribed special trays can be helpful in everyday dental practice. Guidelines are suggested for the design of custom trays, that will, hopefully, lead to improvements in the quality of working impressions.
Forensic organizations worldwide have recommended that dental prostheses should be labeled with at least the patient's name and preferably with further unique identifiers such as social security number, etc. The practice of denture marking has been conducted over many years and several denture marking systems have been reported in the dental literature. However, very little is known about the resilience of such systems to conditions experienced in the majority of post- and perimortem assaults. The purpose of this investigation therefore, was to expose a selection of 10 denture labels to a series of hostile environments. Results of the study indicate that the majority of the denture labeling systems appear capable of withstanding a range of common, and not so common postmortem assaults. With regard to thermal insult, however, most performed badly with the exception of a label constructed from stainless steel orthodontic band. However, another label in the form of an electronic RFID-tag performed above expectations in the majority of experiments. Furthermore, its cosmetic appearance has proven most popular with many patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
