“…Both studies examined the effect of LLLT on post-extraction pain using a randomized double-blind design. In the first study, 75 64 patients undergoing the extraction of bilaterally impacted mandibular third molar teeth were assessed. One side was treated with LLLT, while the other side was treated using an apparently identical but non-operating laser.…”

Despite more than 30 years of experience with low level laser therapy (LLLT) or 'biostimulation' in dentistry, concerns remain as to its effectiveness as a treatment modality. Controlled clinical studies have demonstrated that while LLLT is effective for some specific applications, it is not a panacea. This paper provides an outline of the biological basis of LLLT and summarizes the findings of controlled clinical studies of the use of LLLT for specific soft tissue applications in dentistry. Areas of controversy where there is a pressing need for further research are identified.

“…Considerable basic research has been undertaken since the 1970's. Latest investigations, in particular animal [4][5][6][7][8][9][10][11] and well controlled clinical studies in the field of dentistry [12][13][14][15][16][17][18], however, were often contradictory about the presumed benefits of the laser treatment. Difficulties in measuring operating variables related to pain and tissue repair in an animal model or a clinical setting emphasizes the need of basic cellular research on laser biology.…”

“…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) .…”

“…In general, the average power of these lasers ranges between 10-to 20W. Lasers used for analgesic, anti-inflammatory and healing purposes are known as low-level lasers or therapeutic lasers, with much lower power (around 30mW) (1,(9)(10)(11)(12)(13) . Pain relief promoted by therapeutic laser application results from inhibition of peripheral nerve action potential, affecting the conduction of the nerve stimuli, reducing or interrupting the transmission of impulses evoked from the nociceptors to the spinal cord (14) .…”

“…Despite these good results, the analgesic properties of low-level lasers remain controversial in the current literature. Some reports have not identified improvements in healing or postoperative pain in patients undergoing the extraction of the third molar teeth under general anesthesia after intraoperative application of therapeutic laser (9) .…”

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.
