SUMMARY
Since the laser was introduced in dentistry, acontinuing
interest has been shown by clinicians andresearchers. The Er:YAG
laser is a promisingtechnology with various applications in every
field ofDentistry. Compared with other lasers, the Er:YAGlaser can
effectively alter enamel and dentin surfaces
due to its 2.94 µm wavelength emission.
The LightWalker device is a very effective
device which combines the advantages of two
different wavelengths (2.940 and 1.064 µm). The
LightWalker’sX-Runner handpiece further provides a higherprecision
of irradiation and depth of ablation with areduced treatment
time.
Er:YAG lasers are also very effective in ceramicrestoration
debonding. It is well known that theEr:YAG laser is highly absorbed
in composite resins
and is a safe and effective option, which is alreadyused for the
removal of composite resin fillings in theclinic. The transmission
of the Er:YAG laser beamthrough ceramic restorations enables the
debonding ofceramics from the tooth structure.
In the past 30 years, there has been growinginterest in
investigating the effects of Low Level Laser
Therapy and its various clinical applications indifferent
medical specialties, as either a single or acomplementary therapy.
According to the results of arecent clinical study, Low Level Laser
irradiation with
Nd:YAG laser (1064 µm) for pain reduction was verysuccessful in
patient treatments with myofascial paindysfunction syndrome.
This presentation summarizes the differenttreatment
options of the LightWalker device in thelight of current literature
and case presentations.

SUMMARY
A comparison is presented of the abilities of theneodymium
lasers and diode lasers, both of whichemit near-infrared light.
Based on quotes from theglobal scientific literature in the field,
the presentationhighlights the advantages and disadvantages
ofdifferent wavelengths allocated to the differentspecialties in
dentistry. The near-infrared zone ischaracterized by an excellent
absorption of energy inpigments - chromophores (strong absorbers)
in thetissue, most preferably hemoglobin and melanin. Thisfact
qualifies the use of lasers for soft tissues, such as
periodontal applications and surgery, but also forendodontic
disinfection.
A good balance between absorption and
controlledpenetration provides opportunities for popular
diodelasers, with effects approaching those of the gold-standard
Nd:YAG lasers. Laser-tissue interactions,
with a different specificity for each wavelength, evenin
the narrow range of around 1 micrometer, demandsthat we make the
best selection and use of lasers forany particular
manipulation.
The intent of this Laser and Health Academy publication is
to facilitate an exchangeof information on the views, research
results, and clinical experiences within themedical laser
community. The contents of this publication are the sole
