Case Report: A 59-year-old female patient, diagnosed with infiltration by squamous cell carcinoma in the left cervical region, underwent adjuvant cervical-facial radiotherapy with a total dose of 66.6 Gy of radiation. Eight years after the diagnosis, the patient underwent multiple extractions and, subsequently, the installation of osseointegrated implants, evolving to extensive intraoral bone exposure associated with oral cutaneous fistula. The patient was initially exposed to photobiomodulation therapy (PBMT), with a low-power laser at wavelengths of 660 nm and 808 nm, and thereafter to antimicrobial photodynamic therapy (aPDT). After an improvement in the clinical condition and resolution of the oral cutaneous fistula, a surgical procedure with the Er: YAG laser was performed to remove the remaining necrotic bone. Once the ORN condition was completely treated, the patient\u2019s oral rehabilitation was implemented by the installation of an upper mucous-supported total prosthesis and a lower implant-supported prosthesis. Conclusion: The patient is in a clinical follow-up and has no signs of bone necrosis recurrence, suggesting that low and high-power laser treatment can be an effective therapeutic alternative to resolve this condition.<\/jats:p>","DOI":"10.34172\/jlms.2023.58","type":"journal-article","created":{"date-parts":[[2023,12,10]],"date-time":"2023-12-10T07:11:42Z","timestamp":1702192302000},"page":"e58","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Use of Phototherapy and Er-YAG Laser in the Management of Mandible Osteoradionecrosis: A Case Report"],"prefix":"10.34172","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2900-0023","authenticated-orcid":true,"given":"Larissa Couto","family":"de Freitas","sequence":"first","affiliation":[{"name":"School of Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elenice Lika","family":"Kawamoto","sequence":"additional","affiliation":[{"name":"ADOCI Implant Dentistry Improvement Course; S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Maria Aparecida","family":"Souza","sequence":"additional","affiliation":[{"name":"Master\u2019s Professional Program on Lasers in Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo Yataro","family":"Kawasakami","sequence":"additional","affiliation":[{"name":"ADOCI Implant Dentistry Improvement Course; S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alyne Gon\u00e7alves","family":"Sim\u00f5es","sequence":"additional","affiliation":[{"name":"School of Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luciane Hiramatsu","family":"Azevedo","sequence":"additional","affiliation":[{"name":"School of Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"20123","published-online":{"date-parts":[[2023,11,26]]},"reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1007\/s10006-009-0198-9"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1111\/idj.12318"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.1080\/0284186x.2019.1643037"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.1053\/ctrv.2002.0254"},{"key":"R5","doi-asserted-by":"publisher","DOI":"10.4317\/medoral.24132"},{"key":"R6","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2010.02.005"},{"key":"R7","doi-asserted-by":"publisher","DOI":"10.1016\/j.surge.2014.07.003"},{"key":"R8","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjoms.2020.07.031"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.1089\/pho.2013.3493"},{"key":"R10","unstructured":"de Paula Eduardo C.
