Low-Level Laser Therapy in Dentistry: Applications beyond Soft Tissue Surgery

With the development of the technology of dental lasers, the field of modern dentistry has widened beyond the scope of soft tissue surgeries. There are some applications of the new type of dental laser machine that are currently under research. One of them is low-level laser therapy (LLLT). Low-level laser therapy is known as photobiomodulation therapy. This type of treatment is interesting to study, as it has the potential to be used for pain management and control of inflammatory processes. Unlike surgical laser treatment that requires ablation of tissues, LLLT applies particular wavelengths of light to influence the biological systems in order to obtain the desired effects without cutting tissues.

Pain Management and Post-Treatment Recovery

Inflammation and pain are typical issues that can appear after various kinds of dental treatments such as tooth extraction, root canal therapy, periodontal treatments, and orthodontic manipulation. Low-level laser therapy is considered to be helpful in the process of dealing with these problems. Through its effects, photobiomodulation may help in relieving pain and promoting recovery processes in the body by influencing inflammatory processes and cellular activities. Laser therapy is not an invasive procedure because there is no need to cut tissue and make any changes in the body during the procedure.

In some cases, patients will need to recover after some dental procedures, and in some cases, the low-level laser therapy will come in handy. After some dental procedures, patients may have tenderness, swelling, or pain, and laser therapy will come in handy after the procedure in such cases. But the outcomes will differ according to the nature of the procedure, patients’ individual characteristics, and laser therapy parameters. The dentist should evaluate all the available information regarding the clinical practice of using this technique and apply it accordingly.

Applications in Periodontal and Endodontic Treatments

The application of laser therapy is associated with various medical issues, but periodontal and endodontic therapy represent two different kinds of treatments that can be affected by low-level laser therapy. Photobiomodulation can be used in periodontal treatments as an adjuvant therapy to support the process of recovery and to help in the management of postoperative pain. 

Low-level laser therapy application in endodontics helps minimize the postoperative pain following root canal treatment. Some data confirm that in certain cases, low-level laser therapy can provide an extra pain-relieving effect, although results of different studies vary. 

Exploring Applications Beyond Conventional Laser Surgery

LLLT is also under study for its use in orthodontics and other fields of dentistry. Orthodontic patients often suffer from pain after the fitting or readjustment of their braces and other orthodontic appliances. LLLT has been tested to possibly help reduce the pain and affect biological reactions related to the process of orthodontic tooth movement. However, different studies provide inconsistent results and do not support the effectiveness of treatment across all protocols.

The other possible application of LLLT is to enhance wound healing after some oral surgical procedures and oral mucosa diseases. It demonstrates that the laser technique can be applied not only to cutting or ablation of soft tissues. But it would depend on the kind of disease, the wavelength, and the energy settings, as well as the mode of application. There are several articles written on this topic. The dentist should consider these articles. This will help set proper patient expectations.

Major Applications of Low-Level Laser Therapy

A. Pain Management 

• May assist in the management of pain after certain dental procedures.
• Has been researched for its possible impact on post-operative inflammation.
• May be used along with conventional therapies if there is proper clinical evidence.

B. Tissue Healing and Periodontics

• May assist in biological processes related to tissue healing.
• Has been researched as a supplementary treatment to conventional periodontal treatment.

C. Orthodontics and Endodontics

• May assist in reducing pain after orthodontic treatment in certain cases.
• Has been researched for pain after root canal treatment.
• Needs proper treatment protocols depending on the clinical condition.

Choosing Suitable Laser Equipment for Dental Practice

Specifications of the equipment must be consistent with the intended procedures that a dentist wishes to conduct. Training needs, maintenance, manufacturers’ instructions, and regulatory certifications must also be taken into account when purchasing a certain system.

Diode Laser Dentistry is capable of being used for various therapeutic approaches, which depend on the wavelength, configuration, operating modes, and power of the diode laser machine. Some types of diode lasers are designed for soft tissue procedures, while there are also configurations and diodes capable of photobiomodulation. 

Benefits, Limitations, and Clinical Considerations

The possible benefits that it can provide include assisting in tissue repair, managing pain, and being another way to treat some types of inflammation. Since photobiomodulation is concerned with biological reactions, but not with surgical intervention, it does not fit into the scope of traditional laser surgery. In this regard, it becomes applicable for dental practitioners who look for other ways to help their patients recover.

Nevertheless, there are still some issues with this type of treatment. Due to different wavelengths, dosages, application procedures, and research methodologies, it is hard to compare the results of applying this method to different dental disorders. Some of the applications have enough evidence, while others are required to undergo further research. Incorrect application of this procedure can result in reducing its efficacy or even cause some safety issues.
