, Surgical lasers cut tissue; and are used for performing surgery, removal of
'lumps and bumps', and other ablative laser procedures. What is the
mechanism of action for surgical lasers? - 🧠ANSWER ✔✔Photothermal: the
laser light has a very high power density and causes excessive heating of
water molecules, which vaporizes the water, "explodes" the cells, and thus
cuts the tissue.
Therapeutic lasers help to enhance tissue healing, and are used for pain
management, wound and injury healing, and other uses. What is the
mechanism of action for therapeutic lasers? - 🧠ANSWER ✔✔Both A and C
are correct (Photochemical and Photobiostimulative)
Wavelength measures the distance between two corresponding points on
adjacent light waves, for example from one peak to the next, or from one
trough to the next. Which is the proper unit for measuring wavelength? -
🧠ANSWER ✔✔nanometers (nm)
t or f- Compared to healthy cells, compromised or unhealthy cells in tissues
that are injured or damaged are more 'reduced'. This means that damaged
cells will more readily absorb oxygen; and therefore damaged tissues will
respond more readily to laser therapy. - 🧠ANSWER ✔✔true
