Ultimately, 40 RCTs were included, and a meta-analysis was conducted using Review Manager 5.4. The primary outcomes included pain, pain-free opening (PFO), maximum-unassisted opening, and maximum-assisted opening (MAO).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>PBMT significantly reduced pain at the third assessment (T2). The optimal parameters included wavelengths (951\u20131070 nm) and output power (below 100 mW). Additionally, PFO and MAO significantly improved at T2. Treatment durations exceeding 10 weeks were most effective for articular\u2013muscular TMDs, whereas shorter durations were more beneficial for purely articular or muscular TMDs. Three to four sessions per week yielded the best outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Effective pain reduction was achieved with high wavelengths (951\u20131070 nm), low power (&lt;100 mW), and frequent, long-term treatment (3\u20134 times per week over 10 weeks). Avoiding high energy consumption over a short period was crucial. This approach is more effective for articular\u2013muscular TMDs than for purely articular or muscular conditions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/25785478251398315","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T06:10:00Z","timestamp":1787119800000},"page":"138-156","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Photobiomodulation Therapy Irradiation Intensity, Frequency, and Duration on Pain, and Functional Improvements in Patients with Temporomandibular Disorder"],"prefix":"10.1177","volume":"44","author":[{"given":"Soo-Min","family":"Ok","sequence":"first","affiliation":[{"name":"Department of Oral Medicine, Dental and Life Science Institute, School of Dentistry, Pusan National University, Yangsan-si, Republic of Korea."},{"name":"Department of Oral Medicine, Dental Research Institute, Pusan National University Dental Hospital, Yangsan-si, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hye-Mi","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Dental Clinic Center, Pusan National University Hospital, Busan, Republic of Korea."},{"name":"Biomedical Research Institute, Pusan National University Hospital, Busan, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Woo","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Dental and Life Science Institute, School of Dentistry, Pusan National University, Yangsan-si, Republic of Korea."},{"name":"Department of Oral Medicine, Dental Research Institute, Pusan National University Dental Hospital, Yangsan-si, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Hee","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Dental and Life Science Institute, School of Dentistry, Pusan National University, Yangsan-si, Republic of Korea."},{"name":"Department of Oral Medicine, Dental Research Institute, Pusan National University Dental Hospital, Yangsan-si, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hye-Min","family":"Ju","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Dental and Life Science Institute, School of Dentistry, Pusan National University, Yangsan-si, Republic of Korea."},{"name":"Department of Oral Medicine, Dental Research Institute, Pusan National University Dental Hospital, Yangsan-si, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi Soon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Nursing, Youngsan University, Yangsan-si, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjae.2020.11.001"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/0333102416686302"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jds.2024.08.023"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.4103\/0973-029X.185902"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/healthcare11101443"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/ptj\/86.5.710"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.4317\/medoral.18794"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10022-1054"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/joor.13555"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.48010"},{"issue":"1","key":"e_1_3_2_12_2","first-page":"1","article-title":"Spectral dependence of laser light on light-tissue interactions and its influence on laser therapy: An experimental study","volume":"5","author":"Marshall RP","year":"2020","unstructured":"Marshall RP, , Vlkov\u00e1 K.
