Dental Laser

Dental Laser

These lasers are used to treat periodontitis,including killing bacteria and activating tissue regrowth.soft tissue lasers seal nerve endings and blood vessels while they penetrate the tissue.for this reason,many experience alomost no pain after laser treatment. The lasers also Promote faster healing of the tissue.

Diode Laser

Dental diode lasers,sometimes called soft-tissue lasers,are ideal for procedures that involve cutting or contouring oral soft tissues.Soft tissue lasers are ideal for troughing around preparations sterilizing endodontic canals,treating periodontal disease,and even tooth whitening


Crown exposure:a-c-e,before exposure;b-d-f, after laser exposure




Basic Laser Science


The word Laser is an acroym for Light Amplification by Stimulated Emission of Radiation.A Study of each of these world offers an understanding of the basic principles of how a laser Operates.


Properties of Laser


Velocity:-The speed of Light in a vacuum = 2.99x1010 cm/sec  Amplitude:The total height of the wave from peak to peak.  Wave length:The distancebetween any two corresponding points on the wave   Frequency: A Number of wave cyclesper second.


Comparison between ordinary visible light and Laser Light (Table1)


Visibel Light
Laser Light
Multiple wave length = White light (Polychromatic)
Typically one clour-Monichromatic,Specific ave lenght generated
Non-Directional and Non-forcused
Highly focused and directional - collimated beam
Unorganized
Organized and efficient
Incoherent
coherent
Low intensity 0.1W/cm2
High intensity 10-10w/cm

Advantages of Laser


No anesthesia, no drill


Less blood loss,Less pain hemostatic, analgesic effect.


Reduce post-Operative edema


Less Post-op Scarring.
