Laser is a stimulated monochromatic coherent beam of
radiation providing blood less field of operation. Excellent
healing with minimum post operation pain and
swelling. Laser dentistry has soft and hard tissues components.
Hard tissue laser is absorbed in water and hydroxyapatite
crystals, use a very high wavelength and is
useful in deep cavity preparations with the effect of reparative
dentine formations protecting pulp organ. RCT
is made perfectly sterilized by completely removing smear
layer in the dentinal tubules. Soft tissue laser is absorbed
in chromophores (melanin and hemoglobin) with wavelengths
ranging from 810 to 980 nm and is effective in
laser bleaching, soft tissues surgeries,
