Objectives: To evaluate and compare the degree of surface deposits on the archwires with X-ray diffraction (XRD) technique after a period of 6 and 12 weeks of incubation in artificial saliva. Materials and Methods: The three sample archwires: 1. Stainless steel (Truforce), 2. Beta titanium (Betaforce), and 3. Nickel Titanium (Truflex); each with the dimension of 0.017 Χ 0.025 inch and 50 mm length, were constructed into simulated orthodontic appliance and immersed in artificial saliva of pH 6.76 in three different Petri dishes and incubated for a period of 6 and 12 weeks at 37C in an incubator. Wire samples were examined by using XRD technique for surface deposits. Student's unpaired t-test was done to compare the lattice spacing of the control wire (SS) with the test wires and for the comparison of surface deposits between 6 and 12 weeks incubation. Results: After 6 weeks of incubation, no significant difference in the mean values of the lattice spacing between control wire and the test wires was found. The lattice spacing values amongst these test archwires was also found to be insignificant. The test wires showed similar results even after 12 weeks of incubation. Conclusion: XRD analysis showed deposits on these three test archwires after 6 and 12 weeks of incubation which were insignificant. |
