Abstract: | Aim: To compare the mean shear bond strength (MSBS) of metal brackets bonded with conventional LED or fast halogen units. Methods: This in-vitro comparative study was conducted on 50 extracted human premolars which were randomly divided into 2 groups of 25 teeth each, by lottery method. Following a standard bonding protocol, Group 1, teeth brackets were cured with conventional LED light source and in group 2, by fast halogen light. MSBS was measured using universal testing machine, at a crosshead speed of 1 mm/minute and recorded in megapascals (MPa). Independent t-test was used for comparison of MSBS in both the groups. The level of significance was determined at p≤0.05. Duration of this study was January 2017 to October 2017. Results: MSBS of metal brackets cured with fast halogen (17.60±3.7 MPa) was similar to conventional LED unit (16.66±3.0 MPa). Conclusion: Fast halogens are equally effective for curing brackets, as they give similar bond strength when compared with conventional LED lights. |
