2D Barcodes: A Novel and Simple Method for Denture Identification

Abstract

Several methods of denture marking have been described in the literature. However, most of them are expensive, time-consuming, and do not permit the incorporation of large amounts of information. We propose a novel and simple method incorporating 2D codes which has several advantages over the existing methods. A 2D code was generated in the dental office and inserted into a maxillary denture. The code was then read using software downloaded into a mobile phone giving access to the website containing details about the patient. The denture was also subjected to durability tests, which did not hamper the efficacy of the 2D code. 2D coding for dentures is a simple, less expensive method with the potential of storing a large amount of information that can be accessed on-site by the forensic investigator, thus allowing quick identification of the denture wearer.

Smartphone and Tablet Applications for Crime Scene Investigation: State of the Art, Typology, and Assessment Criteria

“…Therefore, it would seem useful to settle the basis of a theoretical framework, which will help guide research and advancement efforts and aid in developing policies for the use of applications at the crime scene. Further to the analysis of the semistructured interviews and the surveys conducted, the following typology covering the extent of the applications' various uses is proposed: Sensor and perception upgrade (i.e.,: Flashlight ® , QR Reader ® , Compass ' level tool, color interpretation apps such as ColorAssist ). Means of documentation (i.e.,: Camera, Notes, Dictaphone App, MagicPlan CSI ® , 123D Catch ® , DMD Panorama ® , DOFMaster ® , iDof Calc ® ). Procedures, checklists, and decision trees (i.e.,: CASE ® , see below). Memory upgrade and access to data banks (i.e.,: Camera to record the victims' shoe pattern and to have them available when searching shoeprints at the scene; Documed Compendium ® , World Drugs DB ® , 2D barcode reader for denture identification ). Access to calculation modules and facilitate calculations (i.e.,: Time of Death: CSI Forensic Calculator ® , Calculator ). Means of communication and operational coordination (i.e.,: instant messages and images sent with WhatsApp ® between investigators who are simultaneously working at different scenes). Logistical means (i.e., Maps , Google Maps ® ). …”

Técnicas, etiquetas y dispositivos de marcaje de prótesis dentales empleados en odontología forense como medio de identificación. Revisión sistemática de la literatura / Techniques, Labels, and Devices for Marking Dentures used in Forensic Dentistry...

“…De acuerdo con lo reportado en la literatura, se han propuesto diferentes tipos de etiquetas y dispositivos para el marcaje de prótesis dentales, debido al potencial beneficio dentro de los procesos de identificación (33,34).…”

“…De acuerdo con lo reportado en la literatura, la mayoría de estudios se han centrado en el reporte de diversas técnicas, etiquetas y dispositivos para el marcaje de prótesis dentales. Solo unos pocos realmente se han concentrado en determinar qué tipo de dispositivo es realmente el más eficiente en el momento de Si bien este sistema no es tan costoso como se podría pensar, está en entredicho la resistencia a las altas temperaturas, lo que disminuye la eficacia, no de la técnica, sino de la etiqueta per se(33,86,87). Del mismo modo, diferentes autores se han apropiado de la tecnología de identifiresina(79,80).…”

Use of Qr Code as Personal Identification of Complete Dentures – Literature Review

“…The incorporation of the QR code was another aspect that presented different conducts among the studies. In general, itwas reported that the QR code was laminated after being printed and cut, which means that it was wrapped with a layer of laminated paper and then incorporated into the denture by means of a self-curing acrylic resin cover5,6,10,11 . However, Jain et al(2015) 12 presented a new technique using a 1mm thick prefabricated acrylic sheet, which was placed above the already laminated QR code and positioned in the prosthesis, and then the edges of the lamina were fused to the prosthesis by means of self-curing acrylic resin.…”
