Mod 5 Flashcards
What does LASER stand for
light amplification by stimulated emission of radaiation
how are lasers classified
by wavelengths on electromagnetic spectrum
where are all therapeutic dental lasers in the spectrum
infared
does each laser have 100% predictable tissue interaction
yes
lasers are______ color of light
a single color
are lasers visible
most are not
what is the typical tissue interaction of lasers
thermal
what is the term for vaporization of tissue
ablation
what do lasers minimize to promote healing
inflammatory response
what is the effect of the laser dependant on
target tissue and appropriate wavelength
What are the types of lasers
-argon diode nd:yag er: yag ho:yag CO2
what are the lasers that are commonly used in dentistry
diode, nd:YAG, CO2
What is the mechanism of the Diode laser
uses heat to melt the tissue (ablation, vaporization)
what are characteristics of diode
- good hemostsis
- continuous beam
is a diode good in deep pockets
no
what are uses of a diode laser
cosmetic, perio, biopsies, gingivectomies, frenectomies, desensitization, whitening
what does the diode claim to do
regenerate cementum, bone and PDL
what is the first laser in dentistry which cuts quickly and deeply
CO2
what kind of wavelength does a CO2 have
high
CO2 is highly absorbed in what
watery tissues
what does the CO2 create
a char, biological bandaid
what does nd:YAG stand for
neodymium doped ytrium aluminum garnet
how far does the nd:YAG penetrate
deeper than CO2, can remove soft tissue
what kind of beam does the nd: YAG have
pulsed beam for short periods of time
