					       Soft tissue Laser (Diode) in Dentistry

 Types of lasers: Diode (soft tissues), co2, Erbium laser (hard
  tissues).
 Diode laser, the difference between average and exceptional
  results in Dentistry. It needs only 5-10 minutes working time,
  no or little post operative pain, monochromatic, 810
  nanometers wavelength while the curing length between
  430– 380 nanometers.
 Functions of the Diode laser: It uses light to produce
  thermal energy. Light is absorbed by the melanin and
  hemoglobin in the soft tissues which produces heat that is
  responsible for the cutting and coagulation effects.
 Advantages of soft tissue lasers (Diode Laser): improve the
  esthetics, reduce the chair time, increase the success rate,
  decrease the healing time (no sutures needed), decrease the
  shrinkage of tissues, infiltration anesthesia only, less bleeding
  and there is No need for retraction cord packing.
 The uses of Diode lasers in: frenectomies, operculectomies,
  gingival recontouring, removal of growths and lesions
  (fibroma, apthus ulcers, biopsies) and in periodontal
  pocketing to kill the bacteria inside (New technique).
 Effects of lasers on the soft tissues: vaporization of the cells
   coagulation  protein denaturation  carbonization
  (blackening of the tissues with excess water and heat)
  Ablation, incision, sealed and sterilized wound area.
