Benefits to the Dentist

►Saves time - More income►Keeps the Dentist Healthy►Increases Patient Comfort►Enhances reputation►Reduces emergencies►More referrals

Understanding Low Level

Laser Therapy

Electromagnetic Spectrum

Laser Terminology

►Photons * Amplitude►Coherence * Phase►Wavelength * Interference►Frequency * Constructive ►Power Density Interference►Joules * Destructive►Soliton Wave Interference

PHASE

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

INTERFERENCE

•When two waves are in phase & overlap each other

CONSTRUCTIVE INTERFERENCE

When the combined amplitude of waves is greater than individual amplitude, the signal

gets stronger.

DESTRUCTIVE INTERFERENCE

When one wave is peaking & the other is troughing, they cancel

each other out

Canceling Waves

How Energy Heals

►Frequency is the key

►Canceling waves

►Ability to penetrate

►Jack Schwartz

►Yogi

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

Polarization

►Your body’s way of protecting itself against unpredictable energy

Penetration

►The ability to get laser energy deep into the tissue is a key to success

Soliton Wave

AMPLITUDE

Is the Speed that Waves moves

Osmosis

►Nutrients cannot pass through the depolarized cellular membrane of an injured cell

HOW LASER ENERGY HEALS

►Low Level Lasers re-energize sick and injured cellular membranes allowing nutrients to pass through.

Best Laser Results

►STIMULATE• Nerves, bone, joints, tendons,

cartilage & ligaments

►RESONATE• Muscles, organs, glands

►Acupoint Therapy with the right laser

Proprioception to the Brain

Proprioception

Receiving stimulations within tissues of the body

Proprioception

Feedback from the oral area that regulates significant brain

functions

Proprioception Affects

►Over 50% of body functions

►Blood supply to the brain

►Low level electrical feedback to the brain

Dental Distress Syndrome (DDS)

►Affects over 75% of the people in this room!

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.”

CEREBELLUM HYPOTHALAMUS

POSTURE STRESS

Mandibular nerve has fibers connecting with

the Vagus Nerve.

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

Proprioception

►Controls the sympathetic nervous system

►Controls the parasympathetic nervous system

Autonomic Nervous System

►Regulates organ function

►Coordinates sympathetic and parasympathetic nervous systems

Autonomic Nervous System

Stimulation of sympathetic system:►Increases stress►Raises blood pressure►Increases heart rate►Speeds breathing rate►Decreases glandular, stomach &

intestinal function

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
