The use of QR code as an identification method in complete dentures

The identification process in cases of natural disasters and crimes is a necessity in every investigation process. With the technology evolving, new techniques have been developed in order to facilitate identification in an easier and efficient way. In edentulous individuals, dentures are one of the most valuable tools due to the incorporation of elements that can allow identification. In the last years, QR code have been studied for this purpose, since it presents more advantages than other methods. In order to minimize the size of a QR code, titanium and cobalt-chrome pieces were milled in different sizes. Two different ways of reading the QR codes were used. Despite not being capable to read the three different sizes, two of them were perfectly readable. The QR code use in dentures can play an important role, since the information included in it can save lives or help to identify human beings. However, more studies must be done in order to make this a common procedure.
