“…The main difference between our study and that of Eroglu et al [21] may be the energy density of laser, which was 4 J/cm 2 in their study and 10 J/cm 2 in our study. In a recent study and inconsistent with our research, LLLT with 660 nm or 810 nm lasers or their combination was demonstrated to be ineffective for pain relief following tooth extraction [31]. Reduction of pain, swelling, and trismus after the surgical extraction of third molars was also demonstrated using LLLT [24].…”

Background This study aimed to assess the effect of extraoral 940 nm low-level diode laser on pain, edema, and trismus following surgical extraction of impacted mandibular third molars. Materials and methods This split-mouth, randomized, placebo-controlled clinical trial evaluated 25 patients with bilaterally impacted mandibular third molars. One side of the jaw was randomly assigned to the laser and the other side to the control group. The laser quadrant received 940 nm diode laser irradiation (0.5 W, 10 J/cm2, continuous-wave mode, 20 s) at three points in the master muscle in contact mode immediately after surgical extraction of third molar. The third molar in the placebo quadrant was extracted after 2 weeks by the same surgeon using the same standard approach. The pain score was measured at 2 and 7 days postoperatively using a visual analog scale (VAS). To assess trismus, the distance between the incisal edges of the upper and lower central incisors was measured in maximum opening. To assess edema, the distance between the tragus and chin point was measured before and immediately after surgery and after 2 and 7 days. Data were analyzed using t-test, ANOVA, and Bonferroni test. Results The mean pain score in the first 7 days was significantly lower in the laser group (P < 0.05). Edema and trismus were the same in both groups (P > 0.05). Number of analgesics taken was significantly lower in the laser group (P < 0.05). Conclusion Single-session irradiation of 940 nm diode laser can effectively decrease pain following third molar extraction surgery. Trial registration number: IRCT20141209020258N91 on 29/12/2018.

“…In contrast, Eroglu and Keskin Tunc [38] did not show effectiveness with the application of 940 nm extraoral diode laser for reducing pain. Ahrari et al [39] also did not found any significant effect of 660 nm and 810 nm laser (200 mW, 30 seconds radiation to lingual, buccal and occlusal surfaces of the socket, 6 J/area) for reducing pain.…”

Objective — Postoperative pain, facial swelling, and limitation of mouth opening are common sequеlae of lower third molar surgery. The objective of the study was to evaluate the effect of Low- level laser irradiation in controlling these sequеlae. Material and Methods — This randomized, single-blinded, split-mouth pilot study was carried out at the department of oral and maxillofacial surgery, university affiliated hospital, Erbil, Iraq. The study was conducted on 20 patients (13 males and 7 females), with a mean age of 26.3±7.4 years, who needed surgical removal of symmetrical bilateral impacted lower third molars. In each patient, one side was treated by low level laser and the other side was control. Laser irradiation was performed by postoperative single intraoral application of 940 nm laser beam at four points. Pain, trismus, and facial swelling were evaluated at the first, third, and seventh postoperative days. The data were analyzed using Mann–Whitney U test and unpaired t -test. Results — As compared to the control sides, low- level laser irradiated sides showed a significant reduction in visual analogue pain scales (VAS) during the first three postoperative days (P<0.05). The VAS scores of the laser treated sides were 4.46, 4.00, and 3.35 as compared to 6.58, 5.82, and 5.17 for the control sides. The swelling, and trismus were significantly reduced on the first and third postoperative days in the laser treated sides, as compared to the control sides (P<0.05). The facial measurements during the first and third postoperative days were 108.72 mm and 114.77 mm in the laser sides and 113.57 mm and 118.43 mm in the control sides. The degree of mouth opening during the first and third postoperative days were 33.48 mm and 30.37 mm in the laser sides and 27.93 mm and 25.58 mm in the control sides Conclusions — Single intraoral application of low- level laser is effective in reducing pain, swelling and trismus after mandibular third molar surgery. Therefore, it can be used as an adjuvant in controlling postoperative complications after lower third molar surgery.

“…Tabela 1 -Resultados selecionados dos artigos incluídos no estudo, através da análise do formulário adaptado de URSI A abordagem investigativa, focou na avaliação dos diferentes protocolos que utilizaram a fotobiomodulação em casos de exodontias, tendo como um dos intuitos a redução ou eliminação da dor. Os trabalhos avaliados mencionaram o laser vermelho, com comprimentos de onda que podem ocorrer em um intervalo de 630-690 nm; o laser infravermelho, com comprimento de onda acima de 700 nm; a densidade de energia, considerada pela literatura como a relação entre a energia do laser administrada e a superfície irradiada, variou de 2.1-300 J/cm 2 ; a densidade de potência apresentou variação de 4 -300 mW; e a redução ou não da dor (MILETO;AZAMBUJA, 2017;HOSSEINPOUR et al, 2019;AHRARI et al, 2020;FRAGA et al, 2020;DUARTE DE OLIVEIRA et al, 2021).…”

“…O tipo do laser está diretamente relacionado ao comprimento de onda e pode-se verificar a sugestão do laser infravermelho, com comprimentos de onda que variaram na faixa de 780-810 nm (MILETO; AZAMBUJA, 2017;DUARTE DE OLIVEIRA et al, 2021;AHRARI et al, 2020). Apesar do laser infravermelho ter sido indicado em todos os trabalhos, verificou-se protocolos que associaram o laser vermelho e mencionaram benefícios pós-operatórios.…”

Introdução: Procedimentos cirúrgicos envolvidos na exodontia, invariavelmente, geram dor pós-operatória, requerendo atenção do profissional e a administração de estratégias medicamentosas e/ou terapias, com o intuito de fornecer ao paciente maior conforto durante o período de cicatrização. Objetivo. A presente revisão integrativa tem como objetivo analisar a literatura a respeito dos protocolos de fotobiomodulação, que visam a redução ou eliminação da dor pós-operatória, nos casos em que são realizadas exodontias. Material e Métodos: Ampla busca da literatura foi realizada, utilizando as bases de dados PubMed, Lilacs e Cochrane, permitindo o levantamento bibliográfico para a execução do trabalho proposto. Resultados: O levantamento bibliográfico resultou na seleção de cinco estudos que foram analisados através de um formulário modificado de URSI, permitindo o entendimento quanto ao tipo de laser, energia, comprimento de onda, densidade de potência e resposta positiva ou negativa com relação à diminuição ou eliminação da dor. Conclusões: A maioria das análises mostraram resultados positivos quando a fotobiomodulação foi associada às estratégias de redução ou eliminação da dor pós-exodontia. No entanto, padronização e o desenho de novos estudos são cruciais a resultados clínicos ainda mais previsíveis.
