IntroductionThird molar surgery is almost one of the most frequent procedures performed by maxillofacial surgeons. The surgical trauma leads to post-operation complications such as pain, inflammation and trismus.1 About 3-5 hours following surgery, the pain reaches its maximum intensity and may last 2-3 days; and then diminishes within 7 days after surgery.2,3 Moreover, post-operative inflammation disappears 5-7 days after surgery. 4 It has been recommended to use local or systemic steroid and non-steroid anti-inflammatory therapy to reduce inflammation and relieve pain after molar surgery, but these drugs present some side effects, including gastrointestinal issues, systemic bleeding and allergic reactions.5 Several studies have demonstrated that laser therapy can accelerate cell and tissue reconstruction as well as relieve post-operative pain. 5,6 Laser therapy is an open research field. However, some studies have shown useful findings in treatment of dentin hypersensitivity, temporomandibular joint disorders, inferior alveolar nerve paraesthesia resulting from third molar surgery, sagittal osteotomy, trigeminal neuralgia, labial herpes, aphthous ulcers and post-chemotherapy and ray inflammation. [7][8][9][10][11][12] As there are conflicting findings regarding the effectiveness of low-level laser therapy (LLLT) and the importance of controlling third molar surgery's complications, this study aimed to assess the effect of LLLT on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. In this study, we increased the number and variety of studied groups in order to reduce the error rate, in comparison to former researches. To eliminate the possible differences between several people in relevance to pain amount and also their reports on it, a bilateral surgery group was used to study the effects of LLLT on the post-operation pain and swelling. On the other hand, as maximum mouth The aim of this study was to assess the effect of low-level laser therapy (LLLT) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. Methods: A prospective, randomized double-blind study was undertaken on 44 patients at the Dental School, Ahvaz Jundishapur University of Medical Sciences, in 2015. A lowlevel laser was randomly applied on one of the two sides after surgery of 15 patients. The experimental side received 18 J/cm 2 of energy density, wavelength of 980 nm, and output power of 1.8 W. On the control side, a hand-piece was applied intra-orally, but laser was not activated. In addition, in order to evaluate trismus, 13 patients were treated by unilateral laser therapy and 16 patients did not receive laser therapy at all. The laser was administered intraorally on two points of vestibular and lingual sides at 1 cm from the surgery site, and extraorally at the emergence of the masseter muscle, immediately after surgery, and repeated 24 hours later. The pain, swelling and maximum mouth opening (MMO) were compared between the two groups at 24 hours and a week after surger...

“…It is believed that the light may be absorbed by chromophores in the cells (23), providing an increase in the activation of the cytochrome c oxidase pathway (6,16,20). This would generate an increase in the production of ATP and, consequently, induce cell proliferation (5,13).…”

“…The main overall mechanism of action of this therapy is the stimulation of cell metabolism and tissue repair, thus favoring a more effective and rapid response of the tissue or organ exposed to an aggression (4). It has been demonstrated that irradiation with red and infrared lights improves the ATP synthesis and stimulates cell proliferation (5,6). However, the mechanism of action of this therapy is still not completely elucidated (3).…”

Red LED Photobiomodulates the Metabolic Activity of Odontoblast-Like Cells

Phototherapy has been indicated as an adjunctive treatment for tissue repair, including the pulp tissue. However, there are no defined irradiation parameters, which is a great challenge to the clinical use of phototherapy. The aim of this study was to evaluate the effect of phototherapy with red LED on odontoblast-like MDPC-23 cells, using different parameter settings. Cells were seeded (10 4 cells/cm²), incubated for 12 h in complete DMEM and then the culture medium was replaced by DMEM supplemented with 0.5% FBS. After 12 h incubation, irradiations were performed (630±10 nm) using a LEDTable device with a 20 or 40 mW/cm² power density and 2 J/cm² energy dose. The cells were irradiated 1 or 3 times, at 1 min intervals. Non-irradiated cells served as control. The cells were evaluated for viability (MTT assay), total protein dosage (Lowry method) and number of viable cells (Trypan blue). The data (n=12 per group) were submitted to Kruskal-Wallis and Mann-Whitney tests (p=0.05). A single irradiation with 20 or 40 mW/cm² enhanced cell viability, which was negatively affected after 3 consecutive irradiations. Cells irradiated only once with 20 mW/cm² produced more proteins compared with those irradiated with 40 mW/cm². Reduction in the number of viable cells occurred only after 3 consecutive irradiations with 40 mW/cm². In conclusion, red LED was capable of biomodulating the metabolic activities of cultured MDPC-23 odontoblast-like cells. The best cell biostimulation was obtained when a single irradiation with 2 J/cm 2 energy dose and 20 mW/cm 2 power density was delivered to the pulp cells.
