Oral mucositis represents one of the most common and debilitating adverse reactions to cancer therapies, particularly in patients undergoing chemotherapy, radiotherapy, and stem cell transplantation. This painful inflammation of the oral mucosa can significantly limit a patient's ability to eat, communicate, and maintain adequate oral hygiene, thus profoundly affecting the quality of life and even the course oncological treatment.
In recent decades laser therapy low-level light therapy (LLLT) has been gradually integrated into international practice guidelines for Prevention and treatment of oral mucositis.
Recent clinical studies and meta-analyses confirm the effectiveness of this non-invasive intervention, with an excellent safety profile, in reducing the severity and duration of mucositis episodes.
Photobiomodulation PBMT sau Low-Level Laser Therapy This involves applying a coherent (laser) or incoherent (LED) light source with precise wavelengths to the affected tissues. This type of cellular stimulation leads to increased ATP production, reduced local inflammation, stimulated circulation, and accelerated epithelial regeneration. Therapeutic effects are observed in both the prevention of mucositis and the acceleration of healing for existing lesions.
Proven effects of photobiomodulation on oral mucositis:
- Decreased incidence of grade 3-4 mucositis, particularly among patients undergoing
intensive oncological therapy; - Reduction of oral pain and the need for opioid analgesics;
- Maintaining oral feeding, which contributes to nutritional status and
treatment adherence; - Reducing hospital stays and interruptions in oncological treatment;
- Improving the quality of life for pediatric and adult patients, at all stages
treatment.
Protocols Current clinics recommend the use of photobiomodulation in a daily preventive regimen or at a frequency adjusted according to the intensity of oncological treatment.
Application is done at the level of exposed mucous membrane regions (floor of the mouth, inner surface of the lips, tongue, soft palate), with standardized doses and respecting therapeutic wavelengths.
Recommended parameters for therapeutic efficacy:
- THOR laser wavelengths: 660–810 nm, for superficial and deep penetration;
- Session duration: 2–5 minutes per area;
- Duration of therapy: throughout the entire oncological treatment, in a preventive regimen and
therapeutic.
It is important to mention that the technology used in the application PBMT directly influences the efficiency and reproducibility of results. Within our clinic, the protocol is implemented with the help of THOR® system – the solution for oral mucositis is a state-of-the-art laser for photobiomodulation, dedicated to advanced medical applications. THOR is currently the only company holding FDA, CE, TGA, and NATO approvals simultaneously and collaborates with over 70 countries and thousands of reference clinics worldwide. Over time, the devices
THOR has been involved in over 700 randomized clinical trials and over 7,000 scientific publications. This infrastructure and global recognition provide the guarantee of safe therapy and validated, and its integration within the framework Our clinic allows us to offer treatments personalized, in accordance with the latest international scientific recommendations.
The essential role of THOR advanced laser technology PBMT/LLLT:
- Precise intraoral application with a dedicated loop for hard-to-reach areas.;
- Strict control of dose and exposure time;
- Inter-session reproducibility, important in oncology protocols;
- Safety and comfort for the patient, including pediatric cases.
The integration of this therapy within oncological care is supported by prestigious international scientific communities, and the experience gained in centers that constantly use PBMT confirms its effectiveness and clinical relevance.
It is not a therapy complementary, but rather an integrative one, intended to ensure treatment continuity
oncologic and to reduce the risks of severe complications.
Conclusions
- Photobiomodulation is a therapeutic option with excellent safety profile and efficiency in managing oral mucositis;
- It can be used both preventive as well as curative, and supported by solid scientific evidence;
- The implementation within our clinic benefits from standardization, technology adequate and trained teams;
- It's a therapy that brings real benefits in quality of life and continuity of oncological treatment.

Top 10 FAQs from Romanian patients seeking laser treatment for oral mucositis, comparing classic treatments with laser treatments:
Mucositis is a painful inflammation of the oral mucosa, common after chemotherapy or radiotherapy, which leads to ulcerations and difficulty eating or speaking.
- Classic treatments: lidocaine gels, baking soda/salt mouthwash, painkillers (Nurofen, opioids), cryotherapy
- Laser treatment Low-Level Light Therapy/Pulsed-Light and Laser Therapy stimulates tissue regeneration, reduces inflammation and pain, and prevents worsening of mucositis
Patients often feel immediate improvement, right from the first session; treatments only take a few minutes.
- In treating canker sores or mild mucositis: 2–3 sessions,
- In more severe cases (after chemotherapy/radiotherapy): up to 5-10 sessions
- Before or after each radiation therapy session, laser treatment is recommended to minimize damage to the mucosa/soft tissues.
- In traditional treatment, there is a continuous need for gels, analgesics, and daily rinses.
LLLT treatment is very sure, without burns, pain, or side effects, with minimal contraindications – pregnancy or epilepsy.
- Faster healing and no strong medications
- No treatment-induced pain
- Reduce inflammation and local pain
- The possibility of patients continuing a quasi-normal diet.
Yes! The laser is a perfect addition to soothing gels, antiseptic mouthwash, physiotherapy, and a bland diet.
At La Innovation Medical Center, a meeting of Mucositis treatment laser cost 250 RON.
- Classic requires daily medication, can be painful, with possible side effects
- With laser: This is minimally invasive, rapid, relaxing, safe, and reduce or eliminate the need for medication (e.g., Nurofen, anti-inflammatories)
In short, for patients
- Laser treatment (LLLT/PBMT) is a solution modern, painless, care reduction Inflammation, pain, and healing speed, without medication.
- Classic treatments can help, but they come with discomfort, require painkiller consumption, and a longer treatment duration.
- The Medical Innovation, A session costs 250 RON., and customized packages are offered based on severity.
