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...

“…Some authors reported the efficacy of LLLT to be superior to placebo therapy [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and other physical therapies , while, others found no significant differences between LLLT and placebo for the measures of TMJ pain [24][25][26]. However there is an advantage of using LLLT in the treatment of TMDs as it is non-invasive, cost effective and does not have any known side effects.…”

Purpose To evaluate the efficacy of low level laser therapy (LLLT) in the treatment of temporomandibular disorders (TMD) in relation to pain intensity, tender points, joint sounds and jaw movements. Materials and Methods Twenty patients received 6 sessions of LLLT (3 times a week for 2 weeks) with semiconductive diode laser (gallium arsenide; 904 nm, 0.6 W, 60 s, 4 J/cm 2 ). Pain intensity, number of tender points, joint sounds and active range of motion were assessed before and immediately after each session and after 1, 2 weeks, 1, 3 and 6 months. Results Statistically significant results were achieved in all study parameters. Conclusion LLLT promoted satisfactory results in reducing the pain intensity, number of tender points, joint sounds and improvement in the range of jaw motion. Hence it is an effective and efficient treatment method for TMDs.

“…They are reversible therapies mentioned in previous reports as the initial treatment for TMD (Bani & Bergamini, 2001;Fikácková et al;Naikmasur et al, 2008), and are effective in reducing pain and muscular tension. The laser protocol used in the present study was chosen in view to its ability to penetrate the muscle tissue, reducing pain and increasing active range of motion and according to our alterations, also similar to control group.…”

Influence of Laser Therapy and Muscle Relaxant on the Masseter Muscle under Occlusal Wear: An Ultrastructural Study

et al. 2012

SUMMARY:The aim of this study was to analyze the influence of low-intensity laser therapy and muscle relaxant in the characteristic ultra structural masseter muscle occlusal wear. Animals and Methods: 40 male Wistar rats were randomly divided into four groups: the control group (GI), occlusal wear (G-II), laser occlusal wear (G-III), and the muscle relaxant occlusal wear (G-IV). Under general anesthesia given intraperitoneally, animals in groups II, III and IV had unilateral amputation of upper and lower molar cusps to simulate an occlusal wear situation. The masseter muscle G-III received laser therapy (830nm, 4J/cm2, 40mW, f ~ 2mm) and the procedure was subsequently repeated every other day for 14/30 days. G-IV animals were treated with daily injection of dantrolene ® (2.5 mg / kg in 0.5 ml of H 2 O). From 24 hours after the elimination peak. The animals were euthanized with an overdose of anesthesia on days 14 and 30 after the removal of the cusps and the ipsilateral masseter muscle was excised and divided in two, one half was routinely processed for light microscopy and other for electron microscopy. There was no statistical difference between each experimental group and the control and between periods in each experimental group. However, the muscle fibers in the G-II showed the most pronounced changes. There is no causal relationship between muscles fibers injuries and occlusion and, despite signs of muscular tissue injury were more evident in the occlusal wear group. Results indicates a moderate action of laser therapy and muscle relaxants in skeletal muscle.
