What is the determining factor of the level to which laser energy is absorbed by the
intended tissue? - Answer -Wavelength of a dental laser
The term 'laser' is an acronym for? - Answer -Light amplification by stimulated emission
of radiation
The primary effect of a laser within target tissues is? - Answer -Photothermal
Does caries-affected tissue have a higher or lower water content than healthy tissue? -
Answer -Higher
The non-contact of which laser with hard tissue eliminates vibratory effects of
conventional handpieces? - Answer -Erbium lasers
Diode wavelength for soft tissue ablation (eg, frenectomy)? - Answer -810-980 nm
Er, Cr:YSGG wavelength for hard tissue procedures and soft tissue ablation? - Answer
-2,780 nm
ErYAG wavelength for hard tissue procedures? - Answer -2,940 nm
CO2 wavelength for hard tissue procedures? - Answer -9,300 nm
CO2 wavelength for soft tissue ablation? - Answer -10,600 nm
Which lasers have been shown to have an analgesic effect on hard tissues, eliminating
injections and use of LA during tooth preparation? - Answer -Nd:YAG and erbium
lasers
How does OSA occur? - Answer -When the pharyngeal dilating muscles relax, causing
the airway to narrow on inspiration. This in turn lowers oxygen and increases CO2
levels in the blood
How does CSA occur? - Answer -When the brain fails to transmit signals to the
muscles of respiration
