Module II-Lasers in OS and Perio Flashcards
Laser beams _______ soft tissue and ______ blood vessels, lymphatic vessels and nerve endings.
vaporizes, seals
The NEAR ir 808-1064: does it go deep or shallow?
DEEP, difficult to determine amount of ablation
The NEAR ir 808-1064: how is its bacteria fighting capability?
EXCELLENT as long as the bacteria is pigmented
The NEAR ir 808-1064: can it cause thermal damage?
YES if used outside the proper perameters
The MID ir 2780-2940: How efficient and accurate at ablation?
HIGHLY efficient and accurate ablation tool, precise depth and penetration
The MID ir 2780-2940: how are its coagulation skills?
POOR coagulation, minimal depth of coagulation in comparison to diameter of most blood vessels
The MID ir 2780-2940: how is its bactericidal efficiency?
EXCELLENT
The ir 10,600nm: how precise and accurate?
HIGHLY efficient and accurate ablation tool, VERY precise depth of penetration
The ir 10,600nm: How is the coagulation?
EXCELLENT coagulation properties c/o depth of penetration and diameter are nearly equal
The ir 10,600nm: how is the bactericidal efficiency?
EXCELLENT
How much epithelium absorption (%) happens in the NEAR ir spectrum?
ONLY 5% (95% transmits to the connective tissue)
How much epithelium absorption occurs (%) with the MID and LONG ir lasers?
100%
Why use lasers instead of a knife?
less pain, swelling, scarring, more precision and so on
Why is there less scarring when using lasers? (think type of cell that causes scarring)
less MYOfibroBLASTS
What happens to the healing rate when using lasers?
PROLONGED- Blade 7-10days vs LASER 2-3 weeks
