    Author(s): Deepak Kamalanathan*, Nancy Monica R, Sridharan R

    Aim: The purpose of this study was to determine the reliability of 2D (Two dimensional) and QR (Quick Response) coded titanium chips in heat cured acrylic blocks after being treated with heat and acid. Materials and Method: 2D and QR codes were generated using patient?s Aadhaar number and laser engraved into 25 titanium chips of 1.5 X 1.5 cm with thickness of 0.3mm. Laser engraved titanium chips with the patient?s information were incorporated into acrylic blocks of 2cm X 2cm with thickness of 5cm. These acrylic resin blocks were categorized into five groups: I, II, III, IV, and V. Each group contain 5 acrylic blocks, in which first three groups were subjected to various heat treatments in electrical furnace at temperature 350° C, 500°C, and 750°C and last two groups were treated with strong acid like 40% hydrochloric acid and 99% sulfuric acid for an hour. After heat and acid treatme.. Read More»
