Low-Level Laser Therapy (LLLT) is a light source treatment that generates light of a single wavelength. Low-level laser therapy (LLLT) has been used in the medical world for decades. Lasers can be classified as high-powered, low powered, surgical or therapeutic. There is evidence and research that shows that low-powered or therapeutic lasers have anti-inflammatory and bio-stimulatory properties when used on live tissue. Laser technology has the advantage of improving treatment techniques as well as aiding in the healing process.
LLLT is known to offer therapeutic benefits to patients, such as accelerated wound healing and pain relief, however, there is much to be learned about the mechanisms, recognition of the therapeutic area, and how to use the technique in certain medical procedures to reach the treatment goals.
As stated, laser therapy has a long history of medical applications and has started showing a promising future in the dental world. Although laser technology has been used for decades, it is considered a newly developing technique in dentistry and is used by many clinicians in dentistry and we are proud to be one among the many. The healing process, less time consumption and pain relief are some of the reasons for its popularity and use. There is evidence that laser therapy is useful when compared to conventional routine dental care and is rising in popularity among dentists, especially in developing countries.
LLLT is beneficial in controlling orthodontic post-adjustment pain; Low-level lasers do not cut or ablate the tissue. It reduces the secretion of highly pro-inflammatory molecules prostaglandin E2 and interleukin-1 from fibroblast cells that reduces pain after orthodontic tooth movement.
Below are some of the benefits low-level laser therapy in dentistry offers:
In traditional dental procedures, pain occurs due to tissue trauma and the release of inflammatory mediators. This happens once the effect of local anaesthesia is reduced or disappeared. There is evidence that LLLT has an antibacterial effect and acts as an inflammatory agent, also allowing bone growth and simulating collagen. Using LLLT helps relieve pain and repair the wounds easily. The mechanism of this pain reliever is not yet clear however, studies and research show that laser decreases swelling, redness, heat, pain and inflammation by the following mechanisms:
The applications of LLLT in the dental world are wide, we would want to highlight a few of the many applications of LLLT in dentistry:
There are 4 types of low-level lasers that are normally used to treat aphthous ulcers: CO2, Nd:YAG, diode and GaAlAs lasers. Each one is named according to the active medium present. For example, Nd:YAG laser uses neodymium-doped (Nd) yttrium aluminium garnet (YAG) crystals and CO2 laser uses carbon dioxide.
LLLT is currently being followed in all the specialities including orthodontics. At Dental Solutions, we have seen great results with the use of LLLT, wherein it has resulted in a better and patient satisfaction practice. Additionally, decreased treatment timings along with less or no pain procedures. For more information, reach us on WhatsApp
