“…The preliminary results observed in this study are consistent with other studies in the literature that show an analgesic effect of laser therapy on other types of diseases and procedures (16)(17)(18)(19)(20)(21) . Laser therapy stimulates cell growth and division of cells such as leukocytes and phagocytes and improves blood circulation in the irradiated tissue, facilitating the healing process; it also has analgesic effects related to the inhibition of peripheral nerve action potential (14,15) .…”

“…The results revealed that the pain level was lower in the laser group than in the placebo group on the first seven postoperative days. The differences, however, were only significant for the first postoperative day (16) . The use of low-level laser appears to be a simple atraumatic technique for the prevention of mucositis of various origins.…”

“…Thus, otolaryngologists and pediatricians need to find new alternatives to relive or even avoid pain suffered on the days following tonsillectomy. Therapeutic laser is a technological resource widely used in dentistry and oral medicine with favorable results (16)(17)(18)(19)(20)(21) . Due to their anti-inflammatory properties, therapeutic lasers have been used in the prevention of radiation-induced stomatitis and in the postoperative period after endodontic procedures with good results (16,17) .…”

Although there is no other study published to date using low-level laser after removal of palatine tonsils, low-level laser therapy was chosen in this study because our research team believed that it could reduce the child's pain after tonsillectomy, given its role in the acceleration of wound healing and postoperative pain reduction after dental surgery (9,26,27) .…”

Objective:The postoperative period of a tonsillectomy is usually very painful, requiring the use of painrelieving drugs. The aim of this study was to evaluate the efficacy of low-level laser therapy in post-tonsillectomy pain control.Methods: 18 children aged 5 to 15 years undergoing adenotonsillectomy between June 2005 and October 2006 were randomized to receive either local application of therapeutic laser immediately after surgery and 24 hours postoperatively (n=9) or routine analgesic drug therapy, if necessary. Pain was assessed by visual analog scale scores, need for analgesics, and acceptance of diet during the postoperative period.Results: Patients undergoing laser applications had lower median pain scores and required less analgesic medication postoperatively than the control group. Acceptance of diet was similar in both groups.Conclusions: Preliminary results showed that low-level laser therapy is effective in the reduction of post-tonsillectomy pain, minimizing the need of analgesic medication in children and adolescents.Key-words: laser therapy; tonsillectomy; pain; child. RESUMOObjetivo: O pós-operatório da tonsilectomia é, em geral, bastante doloroso e os pacientes necessitam de analgésicos. Este estudo visou avaliar a eficácia da aplicação do laser terapêutico no controle da dor no pós-operatório de tonsilectomia.Métodos: 18 crianças de cinco a 15 anos de idade foram submetidas à adenotonsilectomia, no período de junho de 2005 a outubro de 2006, sendo randomizadas para receber aplicações de laser terapêutico na área cirúrgica imediatamente após o procedimento e 24 horas após a cirurgia (n=9) ou seguir a rotina, com analgesia farmacológica, se necessário. A avaliação da dor foi realizada por escala analógica de dor, pela necessidade de analgésicos e pela aceitação da dieta no pós-operatório.Resultados: Os pacientes submetidos à aplicação do laser apresentaram medianas das notas da escala de avaliação da dor menores e utilizaram menos analgésicos no pós-operatório em comparação aos pacientes controles. A aceitação da dieta nos dois grupos não foi diferente.Conclusões: Os resultados preliminares mostraram que o laser terapêutico foi eficaz na diminuição da dor e na redução de uso de analgésicos no pós-operatório de tonsilectomias em crianças e adolescentes.

Assessment of Low-Level Laser Therapy Effects After Extraction of Impacted Lower Third Molar Surgery

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...
