Background: Oral mucositis (OM) is a debilitating complication of cancer therapy, particularly in head and neck cancer patients, with significant adverse effects on quality of life (QoL). Although numerous interventions have been investigated, their impact on QoL remains inconsistently reported and poorly synthesized. Methods: An umbrella review was conducted following PRISMA 2020 and Joanna Briggs Institute (JBI) guidelines. Five databases (PubMed, Embase, Scopus, Web of Science, and Cochrane Library) were searched from inception to March 2024. Reviews were eligible if they evaluated any therapeutic intervention for OM and reported QoL‐related outcomes using validated tools. Methodological quality was appraised using AMSTAR 2, and findings were narratively synthesized and thematically categorized. The protocol was registered in PROSPERO (CRD420251044088). Results: Eight systematic reviews (257 primary studies) met the inclusion criteria. Photobiomodulation, honey, black mulberry, and botanical agents such as SAMITAL showed consistent improvement in QoL domains, including pain relief, oral function, and emotional well‐being. Gabapentin demonstrated potential in reducing opioid use and early mucositis‐related pain, though findings were mixed across trials. QoL was most commonly assessed using the EORTC QLQ‐C30, FACT‐HN, and UW‐QOL. Overall, heterogeneity in intervention protocols and QoL instruments limited comparability. Conclusions: This review highlights the most promising interventions for improving QoL in patients with OM. Standardizing QoL measurement and prioritizing patient‐reported outcomes in future trials is essential to inform evidence‐based supportive oncology care.

Lately, the use of laser in endodontics has gained acceptance, being considered as a complement to endodontic therapy, which aims to carry out an effective shaping, cleaning and disinfection of the root canal system (RCS), allowing an effective elimination of microorganisms present, and thus prevent reinfection of the canal. Different laser application methods have been adopted to improve the disinfection of the RCS, which could be effective in reducing the microbial population present inside the canals, by activating the irrigant used. The use of laser could also be useful in surgical endodontic procedures which aim to maintain the tooth and its roots when conventional treatment has failed, the positive effects of laser would focus on reducing inflammation and increasing volume, in addition of the reduction in the filtration of orthograde seal materials in apicoectomized teeth. Another use of laser in this area is related to post-endodontic therapy pain management, which has shown promise. Two types of lasers are defined; low-power, which produces a biostimulant, analgesic and anti-inflammatory action of biological tissues, also used in RCS decontamination processes, and high-power or surgical laser, with which incisions, excision, performing cutting functions and coagulation.
