Photobiomodulation: Benefits to Endodontics and Other Potential Applications

Photobiomodulation is a relatively new “secret weapon” in endodontics and other forms of medicine. It almost sounds like something out of a science fiction movie. “Using laser light to make human cells regrow and heal faster? Really?” You bet!

We use photobiomodulation (PBM) as a treatment for certain conditions here at Advanced Endodontics often because it works. Here’s a closer look at what this treatment is, its benefits to endodontic treatment, and some other uses for it.

What is Photobiomodulation (PBM)?

PBM was first developed in the late 1960s, and it was originally known as Low-Level Laser Therapy. Most people are familiar with high intensity lasers, which generate intense amounts of heat. Low intensity lasers are at a different frequency on the light spectrum. PBM treatments are performed these days with low intensity lasers, or high intensity LEDs.

How it Works

The laser light is applied to an area of the body for treatment. The low intensity light from the laser penetrates into the mitochondria level of the cells. When a cell is distressed from pain, a nitric oxide molecule binds to it. The cell stops working and functioning properly due to the nitric oxide.

The laser light used for photobiomodulation knocks that nitric oxide molecule off the cell. Once the cell is free from the nitric oxide molecule, its natural function kicks into high overdrive, and it starts functioning properly. The nitric oxide also binds to an oxygen module and suddenly functions as a vasodilator — meaning it suddenly improves blood circulation and cell oxygenation in the affected area.

In layman’s terms, the low level laser light causes a reaction in pain cells that makes them function properly and increase circulation.

Benefits

The main benefits of PBM include faster healing of wounds and lesions, reduction of inflammation, and pain relief that is sometimes immediate. A PBM treatment session usually only takes about 15 minutes and many patients are surprised by the immediate effect of the laser light. It can take multiple treatment sessions for a wound, lesion, or surgical incision to fully heal from PBM. But the accelerated rate of healing and cell regeneration that it provides is a big surprise to many patients.

Uses in Endodontics

There are a lot of different ways that we can use PBM to benefit endodontics patients. Here is a look at some of the applications of this form of treatment:

  • Post-surgical pain management
  • Improved healing of grafts, implants and other treatments
  • Treatment of dry socket
  • Treatment of facial pain, TMD pain and more
  • Reduces the need to use opioid painkiller and in some cases none is needed at all for post op
  • Regeneration of nerve tissue
  • Treatment of ulcers, cold sores and other soft tissue lesions
  • Treatment of mucositis (oral pain typically caused by chemotherapy)
  • Reduced need for antibiotics (laser light sterilizes treated area)

Other Applications of PBM

Initial clinical testing of low level lasers was done on small animals. It worked so well that pet laser therapy is now one of the most popular pain management methods in veterinary medicine today. For many animals, there are no pain medications that have ever been developed. Yet photobiomodulation works the same way in most types of animals as it does in humans. Veterinarians use laser therapy on everything from iguanas to horses because it works so well.

Medical researchers are continually finding additional ways to use laser light therapy in humans for applications beyond endodontics. Here are some areas where PBM research is showing initial promise:

  • Concussion treatment
  • Alzheimer’s
  • Parkinson’s disease
  • Brain injury
  • Stroke
  • Autoimmune disorders
  • Multiple sclerosis
  • Fibromyalgia
  • Neuralgia (therpetic and trigeminal)

Some chronic pain conditions can last for years. Thus, when those patients undergo PBM therapy, they may suddenly experience pain relief for the first time in a very long time. A side benefit that doctors are noticing in these patients is relief from the depression that often accompanies their condition!
