[Marking of plastic removable dentures with a view to identification].

An easy, cheap and easy to perform method is described for marking of plastic removable dentures that could be used for identification. The method consists of the following: the personal civil number of dentures carrier is typed upon a thin steel band. The band is incorporated in the material for prosthesis during its production or in an already made one. The marking is properly. legible, it is not changed with the use of prosthesis and resistant to temperature over 1000 degrees C.

Principles of forensic dentistry: 1. Identification procedures.

From time to time the general dental practitioner may become involved in forensic cases, when he or she will need to be aware of the general principles involved and the increasing variety of modern techniques available. This two-part article reviews those principles and techniques. In Part 1 procedures used in identifying bodies are discussed. Part 2 will concentrate on non-accidental injury to children and analysis of bite marks, and discuss archaeological investigations.

Copper vapour laser ID labelling on metal dentures and restorations.

Denture marking is accepted as a means of identifying dentures and persons in geriatric institutions, or post-mortem during war, crimes, civil unrest, natural and mass disasters. Labelling on the acrylic resin component of the denture can easily be damaged or destroyed by fire but on cobalt-chromium components it would be more resistant. A copper vapour laser (CVL) can be used to label the cobalt-chromium components of dentures and metal restorations easily, and legibly, and miniaturised for the incorporation of more personal particulars necessary for the identification of the deceased person. The CVL beam is focussed by its optics and delivered to the material surface by the two-axis scanner mounted with mirrors. A personal computer controls the movement of the scanner and the firing of the CVL. The high peak power of the pulsed CVL is focussed to very high energy density producing plasma ablation of the alloy surface. Very fine markings of a few microns width can be produced enabling the storage of detailed information of the deceased person on a metal surface for the purpose of rapid identification.

An inclusion technique for marking dentures.

The importance of placing identification markers in dentures is well documented and this paper describes a simple and inexpensive technique for doing it. Twenty marked upper acrylic simulated dentures and 20 controls (unlabelled) were constructed in a standardized mould. Clear laminated labels were produced in a P-touch 300 electronic lettering system and contained both the patient's identification number and suffix ZA (international code for South Africa). The markings were both clear and aesthetically acceptable. Strength tests were carried out to establish the effect of the mark with the result that no significant difference (p70.05) was demonstrated. The routine marking of all dentures by this method is advocated.

A modified light-cured denture identification technique.

Removable dental prostheses are lost frequently or stolen in nursing homes. Dental personnel may not be routinely available to many nursing home residents to place identification labels, and nursing staff members are not trained to use traditional denture marking techniques. This article describes a modified simple marking technique that may be used by either dental personnel or nursing staff members. Using ordinary sandpaper, lead pencil or ball pen, art and craft brush, direct light, and a mono-poly sealer of 1 part heat-cured clear methylmethacrylate powder mixed with 10 parts of autopolymerizing clear orthodontic methylmethacrylate liquid, 26 dentures were labeled for 19 nursing home residents. The technique was quick, cheap, easily applied, nonirritating to mouth tissues, and permanent.

[Identification systems for dental prostheses using fluorescence techniques].

The dental description of unknown or missing persons in case of mass disasters such as fire, drowning and individual accidents is a very successful odontological mean of identification in forensic research. Difficulties arise if the natural dentition is gone for one reason or another or has been replaced by a dental prothesis. From a dental-prosthetic point of view, this can be prevented by using denture marking in order to give this registration a more personal character, an application from the fluorescence technique was chosen, enabling to mark the denture base with an adequate and inconspicuous code when fabricating the prothesis. This preventive registration may be read in the visible spectrum with the proper equipment at a specific frequency. In view to an increase in the percentage of old people and inherently an increased use of prosthetic appliances with this population, registration by means of the fluorescence technique will be most useful to the forensic odontologist in his identification research. Other useful indications are patients in hospitals, parental homes, nursing-homes and mental homes. To prevent exchange or the loss of prosthetics.

On denture marking.

During the last decades in Sweden dentures have been permanently marked with a stainless steel metal band incorporated into the acrylic and containing the patient's birth date, a special number, and "S" for Sweden. The last recommendation issued by the National Board of Health and Welfare states that "the patients shall always be offered denture marking and be informed about the benefit thereof. Denture marking is not permitted if the patient refuses it". Requirements for denture markers have been that they should be biologically inert (when incorporated into the denture), not be expensive, be easy to inscribe, be possible to retrieve after an accident, and survive elevated temperatures for a reasonable time under normal circumstances. Although the frequency of edentulousness has decreased in recent years due to the improvement in oral health there remains a need to address the issue of marking of complete dentures, because there is a large variation in the oral status of populations in different countries. Given that only one marked denture can reveal the identity of a deceased person when all other methods fail to do so, makes it worthwhile. Furthermore, denture marking is important in long-term care facilities. We have investigated the issue of denture marking in Europe and in the United States. The results from the European survey show that denture marking is, to our knowledge regulated by law only in Sweden and Iceland. In the US denture marking is so far mandatory in 21 states while New York State requires dentures to be marked if the patient requests it and several other states impose the obligation to mark dentures on long-term care facilities. Since there is no international consensus regarding the issue of denture marking it is important to address it. A survey from the Nordic countries has shown that if denture marking was in general use, the contribution to the establishment of identity by forensic odontology in cases of fire would increase by about 10%. This means that about 25 more individuals could have been identified if their dentures were marked. Increased international collaboration is needed to solve the issue of denture marking for clinical and forensic purposes.
