Denture Marking for Forensic Identification Using Laser-Marked Stainless Steel Quick Response (QR) Code

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.
