Efficacy of light-emitting diode (LED) photobiomodulation in pain management, facial edema, trismus, and quality of life after extraction of retained lower third molars

Abstract

Background:In dentistry, one of the most common surgical procedures is the removal of retained third molars. This surgery generates great morbidity to the participants for causing pain, edema, and trismus due to surgical trauma. The objective of the present study is to evaluate the efficacy of photobiomodulation with light emitting diode (LED) in the control of pain, facial edema, trismus, and quality of life resulting from the extraction of retained lower third molars.Methods:A randomized, double-blind, placebo-controlled clinical trial involving 38 adult participants, who meet the criteria of eligibility and agree to participate in the study. Before the surgeries are performed, the facial and mouth opening measures of all the participants will be taken. Immediately after the surgeries, participants will be randomized into 2 groups. In the LED group, participants will receive LED applications (intra oral with 660 nm, 12J and extraoral with 850 nm, 108J) in the immediate postoperative, first and second days after the surgical procedure. In the control group, the participants will be attended in the same way as in the LED group, however, the person in charge of the application will simulate the irradiation. Pain (EVA and NRS-101), postoperative edema, trismus, temperature, dysphagia, and hematoma will be evaluated after 1, 2, 5, and 7 days. The oral health impact profile (OHIP-14 Questionnaire) and anxiety analysis (Beck anxiety inventory -BAI) questionnaires will be applied preoperatively and 7 days after treatment. The appropriate statistical tests will be applied for each specific analysis in a significance level of 5%.Discussion:Although the use of low-power laser in the postoperative has shown good results in the control of postoperative sequelae, this is the first study on the efficacy of the use of LED in this situation.

O estudo comparativo do pós-operatório em exodontias com utilização do laser e sem utilização do laser

“…Esses aparelhos são nomeados de acordo com as substâncias radioativas que eles contêm e essas substâncias podem estar na forma de cristais sólidos, ou na forma de semicondutores diodos que também são classificados pela potência, dividindo-se em laser de alta potência ou de baixa potência (Convissar, et al, 2019;Zerbinati, et al, 2014). Sua eficácia depende dos parâmetros, como o comprimento de onda, potência e energia e diferentes situações clínicas na odontologia requerem diferentes protocolos de LBI (Tenis, et al, 2018). Pedreira e Medrado, et al, (2013) Acrescenta, que o laser é capaz de gerar um feixe de luz monocromático quando provocado por uma fonte de energia.…”

Phototherapy With LED as an Effective Treatment for Chemotherapy-Induced Oral Mucositis in Hamsters

“…15 Clinical studies have also provided promising results of LED therapy. 17,18,28 Corti et al evaluated 12 patients who were affected by hematological tumors and developed OM after high-doses of chemotherapy and were treated with LED. The study showed that LED treatment was safe and capable of reducing the duration of oral lesions.…”

Uso De Laserterapia De Baixa Potência No Pós-Operatório De Exodontia De Terceiro Molar: Uma Revisão De Literatura

“…Além disso, o laser de baixa potência tem sido de grande valia em casos de aftas, tratamento de afecções orofaciais, alveolite, disfunções da ATM, sensibilidade pós restaurações, úlceras, queilite, lesões herpéticas, inflamações de mucosa, remodelação óssea, osteorradionecrose e xerostomia (SANTOS et al,2021). Considerando que a eficácia depende dos parâmetros: comprimento de onda, potência e energia, visto que em diferentes situações clínicas odontológicas requerem diferentes protocolos (TENIS et al, 2018).…”
