Abstract

As presently used in therapeutic medical and dental applications, lasers are, in essence, devices that produce a monochromatic and directional beam of light powerful enough to do biomedical work and with much less electrical energy converted into waste heat. The word Laser is an acronym for light amplification by stimulated emission of radiation.

Diode laser is a solid active medium laser manufactured from semiconductor crystals similar to that found in a light- emitting diode using some combinations of aluminum or indium, gallium and arsenic. Diode lasers emit light when an electric current passes through them. A 940 nm diode laser has been manufactured for clinical use. This machine has a fiber which is constant in diameter of 400 µm but with varying tips. Thus, only the tip needs to be changed according to the usage for a particular patient. The tip most commonly used for endodontic purpose is 200 µm in diameter and 14 mm in length. No studies are available which describe the use of this wavelength for endodontics and its effectiveness in bacterial decontamination. Thus, there is need for developing effective means of removing the smear layer from root canal walls following biomechanical instrumentation.
