Have you heard the buzz about using cold lasers for healing countless ailments? Cold lasers are being used by Doctors, Dentists, Acupuncturists, DO’s, Oral Surgeons, Veterinarians, Chiropractors and the list goes on. Treatment with cold laser therapy is quickly becoming one of the fastest growing segments of alternative medicine.
The first cold lasers were used over 30 years ago. In Europe, Asia and Canada cold lasers have been used routinely for about 20 years and yet in America they are relatively new to mainstream medicine. Why is this? Just 3 short years ago the United States FDA started to give clearance to cold lasers for use in specific areas. For example the treatment of carpal tunnel syndrome (CTS), neck and shoulder pain, and other pain treatment applications.
Additional names that are often used interchangeably with cold laser are: low level laser (LLT), photobiostimulation laser, photobiomodulation laser , biostimulating laser, bioregulating laser, soliton laser and soft laser. Until a consensus is reached, the two most important names to remember are cold laser and low level laser, which is often used interchangeably with low level laser therapy (LLLT).
Why is it called a cold laser? A laser that utilizes a diode that is 500 mW or less is called a cold laser because it does not produce enough thermal output to heat the tissue being treated. A variety of cold lasers are available on the market with different power outputs and different wavelengths. Common diode power outputs include: 5 mW, 30 mW, 50 mW, 100 mW, 200 mW and 500 mW. The higher the power output, generally the shorter the treatment.

Is there a difference between a laser and an LED? Yes, it is an important difference, which comes down to coherence and depth of penetration. A cold laser uses coherent, polarized light that is highly focused and columnated, allowing it to travel in a straight line for long distances or to penetrate into the deeper layers of the body. The light from LED’s is monochromatic, non coherent light, which is useful for treatment of superficial tissues such as wounds and skin conditions. In comparative studies, lasers have been shown to be more effective and faster working. Some of the most effective and versatile lasers on the market utilize both laser and LED light output.
Is cold laser therapy scientifically well documented? LLLT will naturally not work on anything, however due to the fact that it treats at a cellular level, it is successful at treating an astounding level of conditions. Some research has failed to demonstrate effect in several indications, however proper treatment is dependant upon numerous factors including dosage, diagnosis, frequency of treatment and treatment technique. More than 2500 research reports are published and more than 100 double-blind positive studies confirm the clinical effect of cold laser therapy. Over 90% of the 370 studies revealed in the limited LLLT dental literature alone verify the clinical value of cold laser therapy.
