Infrared, sometimes called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from the nominal red edge of the visible spectrum around 700 nanometers, to 1 millimeter.

LASER SURGERY
Class 4 > 500 mW Surgical lasers
Introduction
Surgery using a laser to cut tissue instead of a scalpel
Laser scalpel
Highly focused laser beam efficiently ablates (either vaporize or chip away) the living tissue.
At the same time, it seals (welds) capillaries, small blood vessels, lymphatics, and nerve endings, with significant benefits to both patients and surgeons.
MECHANISM OF ACTION
Photovaporolysis
Char – remnant of non-fluid cellular component.
Photoplasmolysis
Crater
Zone of carbonization- the limit of vaporization
Zone of coagulation and thermal necrosis- Slightly farther away from the center. This zone will eventually die.
Zone of hyperthermia- Farthest from the center. Beyond these zones there is no effect Depth of the crater and the diameter of these zones are directly related to power density.
20-watt Carbon Dioxide laser with plume evacuator
Highly absorbed by water, making it perfect for tissue cutting, vaporization and acoustical destruction.
Thermal injury to surrounding tissue is very superficial.
Lateral thermal injury of 0.05 mm to 0.1 mm
Because there is such minimal lateral thermal damage, injury to surrounding tissues is limited to what you see during application of the laser energy.
General parameters for CO2 laser use
Routine incision: Spot Diameter: 0.4 mm
Power Setting: 6 to 10 W
Routine ablation/vaporization Spot Diameter: 0.8 mm
Power Setting: 10 to 20 W
Delicate location incision: Spot Diameter: 0.3 to 0.4 mm
Power Setting: 3 to 6 W
Routine excision: Spot Diameter: 0.8 mm
Power Setting: 8 to 15 W
LASER USES
Less Pain - The laser seals nerve endings as it cuts. So the patient will have less pain.
Less Bleeding - The laser seals small blood vessels during surgery and speeds up surgery by minimizing bleeding.
Less Swelling - No physical contact except the invisible laser beam. The tissue will not be crushed.
Sterilization - The laser sterilizes the surgical site as it cuts. Bacteria and viruses are vaporized by the laser during laser surgery.
Faster Recovery - Less bleeding and swelling will result in faster healing.
Precision - The beam direction and power can be controlled precisely to remove thin layers of tissue and produce minimal side effects on the surrounding healthy tissue.
Reduced hospitalization time - All above factor will greatly reduce the procedure time.
Laser surgery benefits for surgeons
Unique surgical capabilities: Laser surgery improves many surgical procedures by making them simpler and reducing risk. This enables surgeries that are not practical with conventional methods.

Light is an integral part of our life. Advances in technology are increasing and changing the ways that the patient experience dental treatment. One of the milestones in technological advancements in dentistry is the use of lasers The early 20th century saw one of the greatest inventions in science & technology, in that LASERS which later went on to became a gift to health sciences. Albert Einstein is usually credited for the development of the laser theory. He was the first one to coin the term “Stimulated Emission” in his publication “Zur Quantentheorie der Strahlung”, published in 1917 in the “Physikalische Zeitschrift”
Lasers are devices that produce beams of coherent and very high intensity light. The word LASER is an acronym for “Light Amplification by Stimulated\Emission of Radiation”. A crystal or gas is excited to emit light photons of a characteristic wavelength that are amplified and filtered to make a coherent light beam. The effect of the laser depends upon the power of the beam and the extent to which the beam absorbed. Several types of lasers are available based on the wavelengths. These range from long wavelengths (infrared), to visible wavelengths, to short wavelengths (ultraviolet), to special ultraviolet lasers called excimers. Lasers are used nowadays in many areas in the field of dentistry It is of the most captivating technologies in dental practice. Even though, introduced as an alternative to the traditional halogen curing light, laser now has become the instrument of choice, in many dental applications. Its advancements in the field of dentistry are playing a major role in patient care and well being.

10. MONOCHROMATIC The light emitted from a laser is monochromatic , on other words, one wavelength (color). In contrast, ordinary white light is a combination of many different wavelengths (colors). LASER PROPERTIES
12. LASER PROPERTIES COLLIMATED A laser has a very tight beam that is strong and concentrated. A flashlight, by comparison, releases light in many directions, the light is weak and diffuse.
13.
14. Pulsed Emmissions The words pulsing and frequency are used interchangeably to describe the same concept, which is the interruption of energy flow on a predetermined basis. Some manufacturers have laid claim to special frequencies, claiming that they produce better clinical outcomes. Peak Power = pulse energy/pulse x duration A 75 W peak power system with a 1 ms pulse has a pulse energy of 75 mJ… Power = pulse energy x rep rate; 75 mJ laser at 10 Hz = 750 mW
15. Continuous Wave Emission Continuous wave emission lasers have no interruption during the delivery of their energy

25. Absorbtion Cellular action spectra has been determined to be from 500 nm to 1100 nm The Chromophore (photoreceptor) is believed to be Cytochrome C Oxidase, which is in the mitochondria and is instrumental in cellular respiration .
26. Important Factors For effective penetration, light needs to avoid scattering and surface absorption.
27. Scattering A beam of light focused on tissue may be reflected, absorbed, or scattered. Scattering is wavelength dependent. Longer wavelengths have less scattering. Scattering in tissue broadens the incident beam, decreasing the effective fluency in the intended target area. Doubling the spot size will increase the effective volume by a factor of eight.
28. The Importance of Power The main reason cited for negative findings in therapeutic laser studies have primarily been because of the use of very low dosages.
29. The Power of the Pilot DVM Laser Power = Energy/Time 1 Watt = 1 Joule/Second Your 9 watt Pilot DVM Therapy Laser™ delivers 9 joules/sec. Over a period of one minute your laser delivers 9 joules/sec x 60 sec/min = 5400 Joules/min .
30. Power Density vs. Energy Density Power Density (irradiance) The power of the laser per unit area Irradiance (PD) = W/cm2 Energy Density (fluence) The power density multiplied by the exposure time, measured in Joules/square centimeter Fluence (ED) = Joules/cm2
31. Power Comparison The Erchonia 3LT™ laser PL3000 5mW laser delivers 0.005 joules/sec. Over a period of one minute this device delivers 0.005 joules/sec x 60 sec/min. = 0.3 joules /min. The Respond 2400XL500P™ has a 500mW head delivering .5 joules/sec. Over a period of one minute this device delivers .5 joules/sec x 60 sec/min. = 30 joules/min. The Pilot DVM Therapy Laser™ delivers 540 joules/min
32. Spot Size & Power Density Spot Size The advanced solid state technology and the innovative hand-piece of the Pilot Therapy Laser™ safely delivers a high dose of photons over a large area Power Density Indicates the degree of concentration of the power output. It is measured in watts per centimeter squared (W/cm2). PD = W/cm2

41. Acute Inflammation Reduction How does Photobiomodulation reduce inflammation? Stabilization of the Cellular Membrane • Ca++, Na+ and K+ concentrations, as well as the proton gradient over the mitochondria membrane are positively influenced. This is accomplished in part by the production of beneficial Reactive Oxygen Species aka (ROS). • These ROS’s modulate intracellular Ca++ concentrations and laser therapy improves Ca++ uptake in the mitochondria.
42. Acute Inflammation Reduction Stabilization of the cellular membrane Enhancement of ATP Production and Synthesis ATP production and synthesis are significantly enhanced, contributing to cellular repair, reproduction and functional ability Photonic stimulation of Cytochromec Oxidase, a chromophore found on the mitochondria of cells, plays a major role in this rapid increase in production and synthesis of ATP.
