POSITIVE EFFECT OF 635 NM LOW LEVEL LIGHT THERAPY ON POSTOPERATIVE HEALING OF SECONDARY CHRONIC OST


ABSTRACT:Introduction: Osteomyelitis of the jaws is a common disease of the maxillofacial region. The goal of each treatment modality for osteomyelitis is to alleviate pain, reduce infection, inhibit the progression of the disease, and induce bone and mucosal healing. Besides antibiotic therapy, surgical management, and oxygen hyperbaric therapy new therapeutic strategies for the treatment of osteomyelitis are developed. One of the novel approaches is photobiomodulation therapy, or Low-Level Light Therapy (LLLT). Material and methods: After surgical treatment, test group patients (n=4) were treated with LLLT for five sessions with an extraoral pulsed 635 nm LED lamp (Repuls7, Repuls Lichtmedizintechnik GmbH, Austria), maximum output power: 140 mW/cm2, frequency: 2,5 Hz, duty cycle: 50%. Clinical achievement and patient pain perception (via VAS score) were evaluated at 1, 3, and 6 months follow-up appointments and compared with control group (n=4) patients, treated with standard therapy. Results: At 3 and 6 months clinical achievement was better in patients treated with LLLT. Pain and discomfort resolution was significantly greater in the experimental group. Conclusions: Taking into consideration the results of this study it can be concluded that low-level light therapy (LLLT) improved the clinical outcome of surgical and medical treatment of secondary chronic osteomyelitis of the jaws. Also, pain and discomfort were significantly reduced in patients treated with LLLT.
