1. USES & BENEFITS of LLLT in DENTISTRYExhibitors SymposiaALD Mar 5, 2004 Dr. Larry Lytle BS, DDS, Ph.D Low Level Laser Consultant

2. Benefits to the Dentist • Saves time - More income • Keeps the Dentist Healthy • Increases Patient Comfort • Enhances reputation • Reduces emergencies • More referrals

3. Understanding Low Level Laser Therapy

4. Electromagnetic Spectrum

6. Laser Terminology • Photons * Amplitude • Coherence * Phase • Wavelength * Interference • Frequency * Constructive • Power Density Interference • Joules * Destructive • Soliton Wave Interference

7. PHASE • Two waves are peaking and troughing at the same time even though they have different frequencies or amplitudes

8. INTERFERENCE • When two waves are in phase & overlap each other

9. CONSTRUCTIVE INTERFERENCE When the combined amplitude of waves is greater than individual amplitude, the signal gets stronger.

10. DESTRUCTIVE INTERFERENCE When one wave is peaking & the other is troughing, they cancel each other out

11. Canceling Waves

12. How Energy Heals • Frequency is the key • Canceling waves • Ability to penetrate • Jack Schwartz • Yogi

13. Power Density • Light concentration – W/cm2 • More power is not better • Body sets up impedance, or polarizes against, too much power and becomes less effective

14. Polarization • Your body’s way of protecting itself against unpredictable energy

15. Penetration • The ability to get laser energy deep into the tissue is a key to success

16. Soliton Wave

17. AMPLITUDE Is the Speed that Waves moves

18. Osmosis • Nutrients cannot pass through the depolarized cellular membrane of an injured cell

19. HOW LASER ENERGY HEALS • Low Level Lasers re-energize sick and injured cellular membranes allowing nutrients to pass through.

20. Best Laser Results • STIMULATE • Nerves, bone, joints, tendons, cartilage & ligaments • RESONATE • Muscles, organs, glands • Acupoint Therapy with the right laser

21. Proprioceptionto the Brain

22. Proprioception Receiving stimulations within tissues of the body

23. Proprioception Feedback from the oral area that regulates significant brain functions

24. Proprioception Affects • Over 50% of body functions • Blood supply to the brain • Low level electrical feedback to the brain

25. Dental Distress Syndrome (DDS) • Affects over 75% of the people in this room!

26. Disease & Stress “Stress, particularly stress of dental origin, pervades man’s life in health and disease. Medicine would benefit by a closer alliance between members of the medical and dental professions.” Hans Selye, MD, Ph.D

27. OVUM Embryology (4 weeks) Ectodermal thickening Neural tube Neural crest Peripheral nervous system Central nervous system

28. Neural Tube Neural Crest Brain & Spinal cord Central Nervous System ½ of master pituitary Thalamus & hypothalamus Outgrowths of forebrain All sensory Receptors Peripheral Nervous System ½ of master pituitary All other hormonal glands Midnose Upper lip Premaxilla Four maxillary incisors Balance of the dental system, except tooth enamel

29. Almost half of the sensory and motor aspects of the brain are devoted to the “dental area.” The Cerebral Cortex of Man by Penfield & Rasmussen Published 1950 by Macmillan Co

30. PROPRIOCEPTION THALAMUS CEREBELLUM HYPOTHALAMUS POSTURE STRESS

32. Mandibular nerve has fibers connecting with the Vagus Nerve.

33. Mandibular Function • 68 Pairs of muscles above and below the mandible determine head, cervical, shoulder, and jaw posturization • The 136 muscles must function at their endowed contracting and relaxing lengths and be in reciprocal balance

36. Proprioception • Controls the sympathetic nervous system • Controls the parasympathetic nervous system

37. Autonomic Nervous System • Regulates organ function • Coordinates sympathetic and parasympathetic nervous systems

38. Autonomic Nervous System Stimulation of sympathetic system: • Increases stress • Raises blood pressure • Increases heart rate • Speeds breathing rate • Decreases glandular, stomach & intestinal function

39. Autonomic Nervous System Stimulation of parasympathetic: • Reduces stress • Lowers blood pressure • Decreases heart rate • Slows breathing rate • Increases glandular, stomach & intestinal function • Builds up body reserves

40. SYMPATHETIC PARA-SYMPATHETIC Sympathetic / Parasympathetic Imbalance

41. Balanced Sympathetic & Parasympathetic PARA-SYMPATHETIC SYMPATHETIC
