  • The exact mechanism is still being explored and debated
  • These chemicals are located in energy compartments in the cell called mitochondria.  When you stimulate cytochromes with the correct wavelength and power of light it provides the cell with extra energy to grow, regenerate and heal. This bio-chemical reaction increases the production of Adenosine Triphosphate (ATP) which initiates vasodilation bring more oxygen rich blood to injured area.

    • 1. LightAmplification byStimulatedEmission ofRadiation http://spaceplace.nasa.gov/en/kids/laser/index.shtml
    • 2.  Gas laser (CO2-welding, surgery) Excimer UV laser (LASIK) Solid-State laser Semiconductor (Telecom, Optical Storage, Laser Pointers) Fiber Hosted (the PILOT Diode Laser) Others-- ◦ Chemical Laser, ◦ Photonic Crystal Laser, ◦ Dye Laser, ◦ Free Electron Laser, etc.
    • 3. High Power Lasers and Low Level Lasers
    • 4. High Power Lasers:Used to cut, coagulate and evaporate tissues. Often called surgical lasers because they can replace the scalpel of the surgeon. i.e. CO2 laserLow Level Lasers:Used for the stimulation of cell function. Their biological effect is not thermal, as is the case with surgical lasers. i.e. LED laser
    • 5. Based on Various Settings: High Power Laser Actions ◦ Vaporization ◦ Hemostasis ◦ Decontamination Low Level Laser Therapy ◦ Biostimulation ◦ Modulation of Pain
    • 6. Vaporization = Cutting◦ The diode laser’s wavelength is absorbed by pigmented tissues and cellular structures resulting in an incision similar to a surgical blade◦ Less thermal damage than other Surgical lasers!  CO2 laser works by boiling water in tissues and rupturing cell membranes
    • 7. CO2 Laser works by thermal action, therefore,some thermal damage is inevitable!
    • 8. Less thermal damage results in less inflammation,and therefore, less swelling and pain
    • 9.  The diode laser’s wavelength is absorbed by hemoglobin Surrounding tissue collagen contraction results in the restriction of blood vessels in the targeted area
    • 10. Active Bleeding Greatly Reduced on Treated Half
    • 11. OPTIONS:“Cut & Sew”HemorrhageDifficult in small mouthElectrosurgeryPost-op swellingCO2 LaserRisk of charring or lasing pharynxDiode Laser ?
    • 12. •Zero bleeding•Limited charring in portionused as “cutting”•Portion used as “pre-coag”followed by blade worked well•No dyspnea during recovery•Eating baby food in 18 hours
    • 13. Treatment with Diode Laser
    • 14. Simple, Fast Extraction Site Closure
    • 15.  Also Known As ◦ Biostimulation ◦ Photobiomodulation ◦ “Cold Laser” therapy ◦ 3LT Because… The mechanism is photochemical rather than thermal
    • 16. Light is absorbed by mitochondria in cells Stimulation of cellular ATP production and up-regulation of nitric oxide Secretion of growth factors, activation of enzymes and other secondary messengers ◦ Enhanced cell proliferation and differentiation
    • 17.  Increased neovascularization and temporary vasodilation “Photomodulation of Blood”– new term in medicine ◦ Enhanced leukocyte (WBC) infiltration ◦ Increased macrophage activity
    • 18.  Increased proliferation of cells ◦ Fibroblasts ◦ Endothelial cells ◦ Keratinocytes Shown to be true of hypoxic or stressed cells Healthy cells show little or no response
    • 19.  Rapid Regeneration of: ◦ Skin ◦ Muscle ◦ Tendon ◦ Ligament ◦ Bone ◦ Nerves
    • 20. 24 Hours– no “red line” Gingivitis Resolved
    • 21. Chronic Scalp Wound Following TraumaMinimal healing over 1st month-Duoderm Paste used
    • 22. Lesion size after 1 month– outlined in redLesion size 24 hours later, following treatment with the Pilot Diode Laser- outlined in green
    • 23.  Lesion-- 7 days, four treatments later
    • 24. •Base of skull on right to caudal scapula•E. Coli was cultured from the wound•Littermates also affected
    • 25.  Immediately Post-OpTreated only caudal half of incision with diode laser following typical debridement
    • 26. Day 4 post-op-Caudal (treated) half shows epithelialization
    • 27. Day 4 post op-Cranial (non-treated) half has more scabbing and inflammation, no epithelialized areas Following day 4, the entire the wound was treated with the Pilot Diode Laser
    • 28. At 15 days post-op, the entire wound was nicelyhealed with an atypically large amount of new hair growth.
    • 29. Infectious dermatitis inthis frog was non-responsive to antibioticbaths and topicaltreatment.The prognosis wasterminally poor.
    • 30. When laser therapy was introduced, antimicrobial treatment was discontinued. Diode laser therapy was applied at 2.0 watts for 2 seconds, twi ce weekly for four weeks. Leg after 2 Weeks of Diode Laser Therapy
    • 31.  Leg following 4 weeks of Diode Laser Therapy
    • 32.  Complete Degloving Injury of Left Humerus
    • 33. Treated with Diode Laser at 2.0 watts for 2 minutes Every Other Day for 2 Weeks
    • 34. No scabbing of the wound was ever noted The owl was released into the suburban wild at 2 weeks
    • 35. In General Increases release of endorphins Increases serotonin Resolution of inflammation at least equivalent to NSAIDs Suppression of nociceptor action ◦ Inhibits nerve conduction in small and medium diameter peripheral nerves
    • 36. Joint Pain Specifically Joint capsule and synovial membrane stimulation result in increased intra-articular circulation and ◦ healthier synovial fluid is generated ◦ Chondroblastic cellular formation is accelerated
    • 37.  Suppression of nociceptor action ◦ Localized treatment ◦ Inhibits nerve conduction in small and medium diameter peripheral nerves Induces neural blockade reducing central nerve sensitisation (pain memory) ◦ Spine and trigger point treatment
    • 38. There are > 50 positive Double Blind studies thatshow clear evidence that Low Level Laser Therapy(LLLT) is highly effective for the following conditions:  chronic pain  acne, eczema  migraines  acute  inflammatory (traumatic) skin conditions pain  wounds and  sinusitis, tonsil  tendonitis burns litis  carpal tunnel  non-healing  TMJ disorders syndrome ulcers  tennis/golfer  rheumatoid  Minere’s elbow arthritis disease  fibromyalgia  Tinnitis  lymph edema  vertigo  osteoarthritis http://www.drz.org/asp/cp/laser2.asp
    • 39.  Cosmetic Uses ◦ Hair Re-growth ◦ Dental bleaching ◦ Non-surgical face lift and wrinkle correction and body contouring ◦ Non-surgical liposuction ◦ Laser enhanced breast augmentation
    • 40.  Back Pain Bowed tendons Navicular disease Bucked shins Laminitis Cellulitis Joint Pain Suspensory ligament desmitis
