Abstract
OBJECTIVES to compare the parameters of pain, oedema, temperature, and soft tissue closure in dental sockets that received two different photobiomodulation (PBM) protocols following extractions. MATERIALS AND METHODS Thirty-one participants had their teeth 38 and 48 extracted. Subsequently, one of the dental sockets received PBM at a wavelength (WL) of 808 nanometers (808 group- nm) and the other dental socket received the PBM at WLs of 808 nm and 660 nm, simultaneously (808 + 660 group). The PBM was applied immediately after the surgical procedure and on the 3rd and 7th days. RESULTS The mean of Visual Analogue Scale (VAS) values for pain were 1.45 for the 3rd day and 0.52 for the 7th day in the 808 + 660 and 808 group, respectively. The mean the pogonion-tragus measurement, used to assess facial oedema on the 3rd day, was 15.38 cm (range 13.5-17.5) in the 808 + 660 group and 15.48 cm (range 14.0-17.5) in the 808 group. The mean facial temperatures in the 808 + 660 group were 34.9 degrees Celsius (ºC) (range 33.5-36.4) on the 3rd day and 35 ºC (range 33.4-36.4) on the 7th day. In the 808 group, the mean temperatures were 34.9 ºC (range 33.9-36.2) on the 3rd day and 34.9 ºC (33.7-36.2) on the 7th day. Regarding the dimensions of the dental socket, the mean were similar for both groups. Significant differences between the groups were only observed in the pain parameter and only on the 7th day, being greater for the 808 + 660 group (p = 0.031). CONCLUSIONS The association of the 660 nm with 808 nm, and the increase in energy did not showed more benefits in pain reduction oedema, or acceleration of the closure of the soft tissues of the dental sockets of lower third molars, in the protocols used here. CLINICAL RELEVANCE There is no need to combine lasers at wavelengths of 660 and 808 nm to reduce oedema, pain and repair of soft tissues after extraction of lower third molars. CLINICAL TRIAL REGISTRATION This trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with the following code: RBR-66pyrh8, on 29th December, 2022.

Abstract
Objective: To evaluate the local and systemic application of photobiomodulation (PBM) to reduce pain after third molar extraction. Background: PBM has been applied locally to reduce pain after third molar extraction, but there are no published studies evaluating its systemic application for this purpose. Methods: Thirty patients with two erupted third molars indicated for extraction were included in this split-mouth clinical trial. Extractions were performed 3 weeks apart in each patient, with one extraction socket being randomly assigned to local and systemic PBM (PBM group) and the other to no PBM (control group). Postoperative analgesia consisted of oral acetaminophen for 3 days. Outcomes included pain (visual analog scale), swelling, and quality of life (14-item Oral Health Impact Profile) assessed before and immediately, 24 h, 48 h, and 7 days after extraction. Results were analyzed by Kruskal-Wallis test, followed by Student-Newman-Keuls test. Results: In the control group, pain increased significantly at 24 and 48 h after extraction (p = 0.0000), decreasing after 7 days (before: 0.36; immediately after: 1.06; 24 h: 4.26; 48 h: 2.53; 7 days: 0.36). In the PBM group, patients reported no pain at all time points, indicating effectiveness of local and systemic PBM in relieving pain after third molar extraction (p = 0.2151) (before: 0.30; immediately after: 0.36; 24 h: 0.86; 48 h: 0.30; 7 days: 0.03). PBM also had a modulatory effect on the inflammatory process and improved comfort after extraction. Conclusions: Combined local and systemic PBM can be useful for pain relief, swelling control, and quality-of-life improvement in patients undergoing third molar extraction.
