of medical lasers.
The laser beam -
high-tech tool that has several unique
properties. These properties - in
particular, excellent absorptivity - led
to the use of lasers to perform a number
of special procedures in dentistry,
surgery, photodynamic therapy. Laser
systems used in dentistry is constantly
evolving. At this stage, conventional
and certified dental laser systems are
divided into working with lasers for
hard tissue and soft tissue lasers.
Lasers for hard
The laser radiation for
solid fabrics are absorbed by
hydroxyapatite (calcium phosphate
present in bones and teeth) and water.
This property makes such a beam is an
excellent tool for cutting a tooth. The
most common dental lasers for hard
tissue are the Er: YAG-laser (Erbium
laser is yttrium-aluminum garnet) and Er,
Cr: YSGG-laser (erbium-chrome laser
The main problem solved with the help of
dental lasers - cutting of bones and
teeth. The laser makes it possible to
conduct such transactions with
unparalleled accuracy. Other common
procedures in the conduct of that use
lasers for hard tissue - training
(giving the desired shape) of the tooth
before applying the composite, the
removal of small pieces of tooth
fillings and correction of defects
caused by wear and tear.
Lasers for soft
The emission wavelength
lasers for soft tissue such that their
light is very well absorbed by water and
hemoglobin (oxygenizing protein in red
blood cells). Common lasers used in
surgery of soft tissues - Nd: YAG-laser
(laser on yttrium-aluminum garnet with
laser diodes. They are frequently
used in periodontal procedures, as they
have a bactericidal action, and
stimulate tissue regeneration. Carbon
dioxide laser is also used extensively
for soft tissue shows great results in
the removal of tissue, causing damage to
a minimum while the surrounding tissue.
Lasers designed for soft tissue, can
clog blood vessels and nerve endings, so
that after surgery the patient with
their application almost feels no pain.
In addition, the laser interference
implies a more rapid healing of wounds.
This effect is the main reason for the
popularity of lasers to physicians who
are engaged in a cosmetic change in the
form of gum.
Today the market of laser medical
equipment is versatile installation
capable of generating a laser for soft
and solid tissues.
Among other ways to use lasers in
medicine should be noted optical
coherence tomography, a noninvasive
method for studying tooth cells using
laser scanning. Also, the laser beam is
used to stimulate natural healing
processes at the cellular level.
