Q:l Whatl typel ofl laserl isl bestl suitedl forl usel onl hardl tissuesl suchl asl inl cavityl prepsl orl tol arrestl bleedingl inl vascularl tissues?
Answer:
Er:YAGl (**Notl surel ifl thisl isl truel orl not.l Can'tl evenl findl wherel it'sl from.)
Q:l Whatl typel ofl laserl isl bestl suitedl forl usel onl softl tissuesl asl inl orall surgery,l implantology,l andl conservativel restorativel work?
Answer:
UltraSpeedl CO2l (**Notl surel ifl thisl isl truel orl not.l Can'tl evenl findl wherel it'sl from.)
Q:l Whatl typel ofl laserl isl bestl suitedl forl usel onl softl tissuesl asl inl softl tissuel management?
Answer:
Diodes
Q:l Diodel lasers
Answer:
-800-1064l nml wavelength
-Infraredl spectrum
-Thel 1064l nml andl 980l nml wavelengthsl arel morel highlyl absorbedl inl waterl thanl thel lowerl wavelengthsl suchl asl thel 810l nm.
-Absorbedl byl darkerl tissuesl andl metalsl thereforel mustl bel carefull whenl usingl nearl implantsl sol asl notl tol heatl metall -->l killl bone
