A Korean company offers technology
for manufacturing compact dental lasers. The laser was
developed for treating hard tissue (teeth), e.g. caries
removal or cavity preparation, as well as for use in
soft tissue surgery. The dual-head laser of Er:YAG and
Nd:YAG series can operate on three wavelengths, namely
1.06 µm, 1.32 µm and 2.94 µm. It size
is similar to that of one-wavelength laser currently
available on the market. The wavelength selection is
done from the control panel. Each pulse duration and
repetition rates were carefully selected to ensure best
efficiency. Laser Head Nd:YAG Nd:YAG Er:YAG Wavelength

Area of Application
Medicine, dentistry, dental surgery:
Hard tissue treatment (cavity preparation; carries removal;
pits and fissures; etching) Soft tissue treatment (gingivoplasty,
gingivectomy; excision of lesions; frenectomy; etc.)
Advantages
Laser operation induces no bleeding
Anesthesia is usually not required No drill noise
