Lasers regenerate teeth

TV, radio and newspapers all over the world got very excited last week reporting that "laser regenerates teeth" following a Harvard study. The study showed that LLLT stimulates the stem cells resident in the tooth pulp to form dentin (details here). This is the highest profile announcement for any LLLT paper ever and will add significant awareness and credibility for everyone in the field. Congratulations and huge thanks to the author Dr Praveen Arany B.D.S., M.D.S., M.M.Sc., Ph.D. who is now a Clinical Investigator at NIH.

Clinical data on Traumatic Brain Injury

ALSO the VA, Boston University and Harvard Medical School published the results of a Transcranial LLLT (LED) pilot study on mild Traumatic Brain Injury. Incredibly; TBI is a leading cause of death and disability among children and young adults in the United States. Each year an estimated 1.5 million Americans sustain a TBI, 50,000 people die as a consequence, 230,000 are hospitalized and an estimated 5.3 million currently live with a permanent TBI-related disability (because there is no cure). This study showed significant improvement in Executive Function, Verbal Learning, Long Delay Free Recall and fewer post-traumatic stress disorder (PTSD) symptoms. Participants and family reported better ability to perform social, interpersonal, and occupational functions. This was a small pilot study on just eleven patients with chronic mTBI, there was no placebo control group so further studies are necessary to truly establish the effect size. Details here.

Literature Watch

173 new LLLT papers for you this time (including the two above). There is my latest review paper on LLLT in dentistry, an LED vs Laser study on oral mucostits and a cost effectiveness study for OM, laser vs corticosteroid for subacromial impingement syndrome, LLLT reduction of postoperative complications Post Myocardial Revascularization, a single case report on LLLT for retinitis pigmentosa, an RCT on carpal tunnel syndrome, a multicentre RCT on Male and Female Pattern Hair Loss, a study on the effect of LED on resorption during orthodontic treatment, a systematic review of LLLT for accelerating tooth movement during orthodontic treatment, the effect of LED on implant stability, LLLT treatment of Chronic Plantar Fasciitis, a TMJ RCT, a wrist fracture RCT, a review of LLLT and photosensitive medication, a fibromyalgia RCT, and another misleading Class IV vs 3B laser study (on knee osteoarthritis).

Two Special Conferences

A joint meeting of the North American Association for Laser Therapy (NAALT) and the World Association for Laser Therapy in Washington DC, USA in 9-12 September 2014. click here. Call for abstracts is still open.

The Optical Society of America hosts "LLLT - the path forward" : LLLT/PBM, is will soon be 50 years old. Hundreds of positive clinical trials and thousands of laboratory studies have been published yet it has not been adopted by mainstream medicine. This meeting will address the reasons for this failure and identify paths forward. Washington DC 20-22 August 2014. This is a small invited guests only meeting, if you would like an invitation then submit your credentials here for consideration.

THOR Training dates and cities:

We study LLLT relentlessly (had you noticed?). We use our knowledge to develop our training, treatments and products. Come see what we have learned since your last training. Now available with Continuing Medical/Dental Education credits.

  • What is the difference between the anti-inflammatory effects of LLLT, the healing and the analgesic mechanisms?
  • Have you thought about treating lymphatics?
  • Are you de-activating trigger points (and how does that work!)?
  • How much LLLT is enough, how much is too much?
  • Joules or J/cm2 - which is the right way to express dose and how is it calculated?
  • Lasers or LEDs, red or infrared wavelengths, high or low power density, pulsed or continuous?
  • Treatment times and treatment intervals and when to expect a result.
  • Safety, contraindications, adverse effects, regulations and reimbursement

It seems like a lot to learn in one day but we use videos, cartoons and a 50 page illustrated book to help you so very little note-taking is required. A certificate of attendance is provided.

Discounts for groups, repeat attendees and early registration.

Rant and Praise - My United Nations presentation (video)

I had 15 mins at the United Nations (Global Health Impact Forum) to pitch LLLT and the startup business I co-founded (Lumithera) to develop LLLT treatments specifically for diseases of the eye. 15 mins was not enough to do LLLT justice but here is the video of my presentation (click here).

ALSO: Ret. Major General Gale Pollock has joined the Scientific Advisory Board of Lumithera. She was acting Surgeon General of the United States Army and Commander of the US Army Medical Command.

More Class IV laser misinformation

The paper "High-intensity versus low-level laser therapy in the treatment of patients with knee osteoarthritis: a randomized controlled trial" Kheshie et al 2014 pitches the 3B BTL laser against the HIRO class IV "High intensity" laser. The results appear to show that the HIRO class IV "High intensity laser" was more effective than the "Low Level Laser", the HIRO class IV "High intensity" laser was delivered over a large area (not adequately defined but approx 100cm2 by my estimation) so the intensity was actually very low (about 13mW/cm2 which is less than most LED systems), and the 3B BTL "Low Level Laser" was actually very high (4 x 200mW small, high intensity beams) and were held stationary on the patella for over half an hour, YES, HALF AN HOUR IN ONE SPOT! This is insane.

This paper leads people to think that the class IV Hiro laser was more effective because it was higher intensity when in fact the beam distribution meant the average intensity distribution was low (13mW/cm2). The 3B laser was not so effective because it was held stationary such that it would cause an overdose. If the 3B laser treatment had been delivered using the same scanning technique as the class IV then they would likely have achieved the same result. (I am not a fan of scanning because you can never be sure how much energy you have delivered to an area, better to use a low intensity device and hold it still in my view).

This paper misdirects the reader towards favouring class IV lasers rather than 3b or LED by misinforming the reader.
