ABSTRACT
Aim and objectives:
To determine the shear bond strength of laser cured composite resin and compare with that of visible light cure resin and evaluate it’s clinical usefulness. Materials andmethods:
An argon laser with a wavelength of 488-500nm and a power density of 2.104 mW/cm2 and an optical diameter of 6mm with a curing time of 10 seconds was employed as against the visible light cure with a wave length of 450-500nm of the same optical diameter and curing time of 40 seconds and tested using a universal instron testing machine.Results:
The bond strength between laser cured and visible light composite resin was not statistically significant. However the lesser curing time of laser reduces the chair side time.Conclusion:
Laser curing of orthodontic brackets may not be a viable procedure due to the cost factor as the bond strength is clinically insignificant.
