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...

“…In recent years, a widely discussed alternative treatment of chronic periodontitis, are lasers. There are many types of lasers like Er: YAG, CO 2 , Nd: YAG, diode, and others, that are used in various dental treatments [3][4][5]. The Er:YAG laser is the most promising laser in periodontal treatment because of its wavelength of 2940nm.…”

Summary Chronic periodontitis is a result of polymicrobial infection and its treatment aims removal of dental calculus and biofi lm from the periodontal pocket. Many hand and power-driven instruments are created for this purpose. In recent years, lasers are widely discussed tools for periodontal therapy. The aim of the present study is to evaluate the early microbiological and clinical effectiveness of the Er:YAG laser in the treatment of chronic periodontitis. 30 patients with moderate chronic periodontitis were enrolled in the study. Using a split-mouth design they were treated either with Er:YAG laser (chisel tip, 100 mJ, 15 Hz, 5-6 water spray)-test group or with Gracey curettes- control group. Probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL), bleeding on probing and plaque presence were evaluated at baseline and one month after the therapy. Microbiological samples were taken from the deepest four pockets of each quadrant from 20 randomly selected patients (n = 80). They were evaluated using real time PCR for periodontal pathogens from the red complex (Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia). One month after therapy in the control group PPD decreased from 4.59 mm to 3.36 mm, the CAL gain was 1.09 mm and the reduction of bleeding and plaque - from 87.9% to 33.7% and from 75.9% to 40.9%, respectively. In the test group PPD decreased from 4.58 mm to 3.15 mm, the CAL gain was 1.37mm and the reduction of bleeding and plaque was from 85.6% to 25.9% one month after the treatment. The results were statistically significant in favour of the laser group (p < 0.05). Microbiological analysis revealed that the pathogens from the red complex decreased 3 times in the control and 6 times in the test group. Therefore, the Er:YAG laser demonstrate pronounced early effectiveness in chronic periodontitis treatment and would be appropriate alternative of the conventional periodontal therapy.

“…In the present clinical report, a severe limited open mouth occurred after the surgical removal of right maxillary thirdmolar in an adult patient and persisted for 56 days. As the use of low level laser therapy (LLLT) for the treatment of musculoskeletal pain syndromes has become common (Kulekcioglu et al, 2003;Grossi et al, 2007;Mazzetto et al, 2007) and the lasertherapy promotes cellular bio-stimulation, accelerates tissue regeneration and wound healing and decreases pain and swelling (Coluzzi and Convissar, 2004), the authors of the present study selected this therapy to be applied in association with an anterior bite plane (occlusal deprogramming) and acupuncture applications, looking for better results.…”

The traumatic removal of the mandibular third molar may promote post chirurgic consequences such as orofacial pain and limited mandibular movements. The aim of this case report is to describe the use of an anterior bite plane and complementary therapies (low level laser therapy and acupuncture) to treat the muscular dysfunction and the painful symptoms. A 33 year-old male patient who had a severe malocclusion and signs and symptoms of temporomandibular dysfunction was submitted to an initial clinical examination: electromyography of the masticatory muscles and IRM of the temporomandibular joint. After treatments, the results showed reduced pain symptoms and an increase of the mandibular movements and adequated electromiographic activities. The authors concluded that the combination therapies may be used as an alternative treatment because it satisfied the functional requirements of the patient and provided an asymptomatic clinical condition.
