Laser Exam UPDATED Exam Questions
and CORRECT Answers
Laser stands for - CORRECT ANSWER - light amplification by stimulated emission of
radiation
Who laid the foundation for the invention of the laser by theorizing that photoelectric
amplification could emit a stimulated emission - CORRECT ANSWER - -Albert Einstein
(1917)
Who first developed the laser? - CORRECT ANSWER - Theodore Maiman
First FDA approved dental laser for clinical use was used in ? - CORRECT ANSWER -
1990 (dLase 300 Nd:YAG-fiberoptic delivery system)
Nd:YAG laser was developed from Neodymium and crystals of Yttrium-Aluminum-Garnet -
CORRECT ANSWER - 1961
First CO2 laser was developed - CORRECT ANSWER - 1964
*Not every laser is cleared for every conceivable use. For any specific laser device, the specific
indications for use, as marketing clearances, can be found in the professional section of the
operator's manual for the device. - CORRECT ANSWER - A FACT
Indications for Diode laser - CORRECT ANSWER - Soft tissue:
-Exposure of unerupted teeth
-Frenectomy
-Gingivoplasty
-Gingivectomy
-Operculectomy
, -Soft tissue crown lengthening
-Gingival troughing
-Biopsy
-Apthous ulcer treatment
-Uncovering dental implants
-Caries exposure
Light - CORRECT ANSWER - -A form of energy that travels in a wave and exists as a
photon particle
Stimulated emission - CORRECT ANSWER - -An excited atom that is stimulated to emit
energy by a direct radiation source.
Work - CORRECT ANSWER - -Stimulated emission that produces a tissue effect
Energy - CORRECT ANSWER - The ability to do work; expressed in Joules or mJ
Joule - CORRECT ANSWER - -Laser energy transferred to an object with 1 Newton of
force for a distance 1 meter
Power - CORRECT ANSWER - -The measurement of work over time; power is
adjustable.
Frequency - CORRECT ANSWER - -Electromagnetic laser were defined as 1 cycle per
second
Energy density/Fluence - CORRECT ANSWER - -Is the measurement of energy per area
of spot size
