Effect of modified intravascular laser irradiation of blood in the oral and systemic conditions during dental treatment-A systematic review

The aim of this study was to investigate the scientific evidence regarding the effectiveness of modified-ILIB (intravascular laser irradiation of blood) in the control of systemic conditions and/or oral changes during dental care. This systematic literature review study aimed to answer the question, "Is modified-ILIB an effective adjuvant therapy in the control of systemic conditions and/or oral changes in children and adults during dental treatment?". The protocol for this systematic review was registered in the PROSPERO database under number CRD42023493800. The search was carried out in the PubMed, Web of Science, LILACS, SCOPUS and EMBASE databases on June 10, 2024. Google Scholar was used as a search source for gray literature. Randomized clinical trials were included, without restrictions on language or year of publication. The RoB 2.0 tool was used to assess the risk of bias and GRADE was used to check the quality of the evidence. A total of 750 articles were retrieved and five studies were selected for this review. All studies were in English and were carried out in Brazil. The outcomes were periodontal parameters and glycemic control in patients with periodontitis and type II diabetes, anxiety control in pediatric dentistry, postoperative pain after third molar extraction and improving taste in post-COVID-19 patients. The majority of studies had a low risk of bias, while only one study was considered to have some concerns. The quality of evidence from the studies was considered very low. The current evidence does not overwhelmingly support the effectiveness of modified-ILIB in controlling oral and/or systemic conditions in dentistry.
