LASERS IN DENTISTRY
A laser is a device that uses light energy to perform work. Lasers are
unique because they can treat targeted tissue while leaving surrounding
tissue unaffected. It is this property among others that allows your dentist
to perform very precise procedures. In addition lasers may seal off blood
nerve endings during a procedure thereby reducing pain and
many cases due to their gentle and precise nature lasers are used with
little or no anesthetic.
How are lasers used in Endodontics
A laser may be used to gain access to
the infected nerve and clean, shape, enlarge and
disinfect the root canal.
Sometimes Dr. Browdy will choose to use the laser to perform only parts of
the procedure. Advantages of using a laser to perform a root canal are that
the procedure oftentimes may be performed without anesthesia and its use
conserves as much natural tooth structure and strength as possible. The
endodontistís goal in root canal therapy is to disinfect the root canal and
fill the area with an
inert material while maintaining as much
strength of the tooth as possible. The precision and disinfecting qualities of
the laser help dentists achieve these goals.
Is this a new procedure?
have been used in medicine and dentistry for many years. The FDA has
approved the use of lasers for many dental procedures including those within
the spectrum of endodontics.
Why does Dr. Browdy use a laser in
addition to other instruments?
Lasers are used because of the precise control they afford the dentist and
the comfort they provide to patients. Lasers perform many functions at once.
Not only can a laser remove tissue but it can also be used to seal blood
vessels and nerve endings, reducing bleeding and postoperative pain and
swelling. Dentists and patients also appreciate that many times a laser may
be used with minimal or no anesthetic.
What about pain?
One of the biggest advantages of laser
therapy is the fact that many times procedures can be performed with much
less postoperative discomfort than with
conventional methods alone. This
is due to the laserís ability to seal off nerve endings and blood vessels
and to be tissue specific during treatment. Hard tissue lasers have been
reported to have an analgesia type effect making the use of anesthetic
unnecessary in many cases. Since hard tissue lasers are used in a non
contact manner there is also less heat and vibration produced versus a
traditional hand-piece or drill which can cause microscopic cracks or
fractures in the tooth.
