Oral mucositis (OM) affects children and young people with cancer treatment, where low-level laser therapy (LLLT) has been suggested as a preventive method. The objective of this article was to analyze, by means of a synopsis, the effects of LLLT on the prevention and treatment of the clinical picture of OM in a pediatric cancer population treated with radiotherapy and/ or chemotherapy. An electronic search of systematic reviews published between 2018 and 2021 was performed in the Medline database, Epistemonikos metasearch engine, and the Google Scholar registry. The search strategy was "low-level light therapy AND oral mucositis AND pediatric patient". Two hundred and seventy-three articles were found, analyzing two systematic reviews. LLLT was shown to reduce the risk of OM (OR = 0.50, 95% CI, 0.29 to 0.87), improving the clinical picture on the 7 th day (RR = 0.90, 95% CI = 0.46-1.78) with few adverse events. LLLT seems to reduce the risk of OM and the severity of the condition, although more studies are required to identify an optimal dose.
La mucositis oral (MO) afecta a niños y jóvenes con tratamiento oncológico, donde se ha sugerido la terapia láser de baja potencia (o LLLT por sus siglas en inglés) como método preventivo. El objetivo de este trabajo fue analizar mediante una sinopsis, los efectos de la LLLT sobre la prevención y tratamiento del cuadro clínico de MO en población pediátrica oncológica tratada con radioterapia y/o quimioterapia. Se realizó una búsqueda electrónica de revisiones sistemáticas publicadas entre 2018 y 2021 en la base de datos Medline, metabuscador Epistemonikos y registro Google Académico. La estrategia de búsqueda fue "low-level light therapy AND oral mucositis AND pediatric patient". Se encontraron 273 artículos, analizándose dos revisiones sistemáticas. La LLLT mostró disminuir el riesgo de MO (OR = 0.50, IC 95%, 0.29 a 0.87) mejorando el cuadro clínico al séptimo día (RR= 0.90, IC 95%, 0.46 a 1.78) con pocos eventos adversos. La LLLT parece disminuir el riesgo de MO y la gravedad del cuadro, aunque se requieren de más estudios para identificar una dosis óptima.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
