Laser History
 Laser – Acronym for word light amplification by
“stimulated emission”
 Principle founded by- Albert Einstein in 1917
 1960, Synthetic ruby laser: Theodore Maimam[2]
 1961, the first gas laser and first continuously operating
laser
 1988, Er:YAG laser
 1989, Nd:YAG laser, soft tissue surgery
Laser Components
 Active medium : solid, liquid or gas
 Laser tube having two mirrors
 Power source of mechanical, chemical and optical
Laser Characteristic
 Laser energy is made of small particle call photon
 Monochromatic (light of one specific wavelength)
 Directional (low divergence)
 Coherent (all waves are in certain phase relationship to
each other)
Why Consider Laser:
 Laser is more efficacious
 Bactericidal properties
 Tissue sterilization and coagulation
 Pain relief
 Inflammation reduction
 Wound healing
 Accelerated tissue repair and cell growth
 Use of laser on implants
Advantages of Laser
 High patient acceptance
 Less bleeding during surgery and post surgery
procedure
 Reduce surgery time and post surgery pain
 Minimal swelling and scaring
 Reaches difficult areas without scaring and
trauma
 No requirement of sutures
Disadvantages of Laser
 Laser irritation
 Need special equipment
 Protective eye wear must be selected based on the laser wave length
 Multiple wavelengths lasers will require switching of safety lens during
procedure
 Cost and size
 Proper training and causes
 Can cause serious ocular injuries if used without appropriate eye safety
devices
 Retinal damage may result in permanent eye problems in the form of diminish
night vision, decreased ability to see color, and even blindness
 Texas Administrative Code, Title 22 Rule #115.2 section
7B states that “Dental Hygienists may use lasers in the
practice of dental hygiene under the direct supervision
of a dentist, so long as they do not perform any
procedure that is irreversible or involves the intentional
cutting of hard or soft tissues.
 Dental Hygienist can use laser for sulcular
debridement, reduction, of subgingival bacterial load,
inflammation control, and homeostasis of bleeding
Recent Advances
 Waterlase system: The ease of laser water that is
energized to cut soft and hard tissues.
 Periowave system: Utilizes nontoxic dye in combination
with low intensity lasers to destroy bacteria by enabling
oxygen.
Laser Safety
 Laser warning sign outside of
clinic
 Use barriers within the operatory
 Use of eye wear to protect
against reflected laser light or
accidental direct exposure
 High volume suction must be
used to evacuate the plume from
tissue ablation.

Conclusion:
 Lasers are advancing and exciting tools providing ease of
access to anatomical areas unavailable with traditional
scalers.
 Laser light have bactericidal properties whereas handheld
tools can themselves become contaminated.
 Lasers in dentistry are invaluable technology improving
upon dental methods of yesterday for benefits of dentist and
patients tomorrow.
