Laser means Light Amplification by Stimulated Emission of Radiation .
A Laser creates a beam of concentrated light , comprised of rays of uniform wave length and direction .
An active medium within the laser is stimulated to emit light energy by an optical resonater , The optical fiber carries laser beam to a light weight control handpiece .Laser beam are invisible or visible light according to the used active medium have different pulses per second , watts , and duration (scattering and penetration)
Oral Laser Applications :
1- caries removal from tooth surfaces
2- pits and fissure sealing
3- vaporizes tissue debris in the pulp and glazing of the chamber
4- subgingival caries removal
5- gingivectomy and gingivoplasty
6- frenectomy
7- operculectomy
8- pocket elimination
9- excision of tumors
10- incision and drainage of abscesses
11- induces analgesia of the tooth
12- eliminates hypersensitivity
13- aphthous ulcer treatment
14- killing of microorganisms during surgical operations
15- sterilization of pulp chamber and field of operation
16- coagulation of blood vessels and stasis of blood
17- seals dentin tubules for teeth hypersensitivity
18- etching of enamel for bonding and debonding of Ortho brackets
19- increases microretention hardness between the composite and tooth
