Abstract
Denture marking is an accurate and rapid method to identify unknown individuals in social and forensic scenarios. Numerous published works have attempted to present various techniques for denture marking; however, not all satisfy requirements either in terms of cost, storage of a large amount of information, and their capability to withstand high temperature. Hence, this article describes a simple, cheap, and feasible denture marking system using laser-marked stainless steel quick response (QR) code. A QR code was generated in the dental office, laser marked on stainless steel band, and inserted into a mandibular denture. The code was then read using an app downloaded into a mobile phone giving access to details about the patient. The code was created to store, modify, and view large amounts of information with smartphones, thus allowing quick identification.
Highlights
The role of denture marking in social and forensic scenarios has long been acknowledged by dentists and forensic odontologists
Quick identification is usually possible when an identification code is embedded in the dentures
The simplicity of using the laser-marked stainless steel quick response (QR) code can enable anyone with a smartphone to access patient information in necessary situations, helping to reveal the positive identity of a person when all other methods fail
Summary
The role of denture marking in social and forensic scenarios has long been acknowledged by dentists and forensic odontologists It helps in identifying dentures and persons in geriatric institutions or postmortem during wars, crimes, and natural and mass disasters. The use of quick response (QR) codes as a method of personal identification in dentures presents most of the requirements recommended in the literature, except for the resistance to high temperatures. QR coding of dentures is simple and cheap, with the potential of storing a large amount of information, allowing fast and reliable identification except for the resistance to high temperature [9]. This article describes an innovative technique wherein a laser is used to mark QR code on stainless steel band, which is inserted in the denture, allowing storage of huge information together with its resistance to high temperature. The QR code will be translated into text on the mobile phone's display (Figure 4)
