Growth of the Omega 3 industry applied in non-surgical periodontal therapies in dental practitioners

The aim of this systematic review is to recognise the effects of dietary supplementation of Omega 3 (fatty acids) as an adjuvant in non-surgical periodontal therapy in patients with periodontitis. In the present research work, a Systematic Review of Randomised Clinical Trials on the supplementary use of Omega 3 in the diet of patients with periodontitis was carried out. The guidelines of the CONSORT 2010 statement were followed using different search equations and previously selected articles. The results show the synthesis of 12 articles selected for this study, providing information such as author, year, journal and quartile classification, among other parameters such as blood biomarkers present and periodontal clinical parameters. In conclusion, the analysis of the efficacy of Omega-3 as an adjunct to non-surgical periodontal therapy (NSPT) shows that, although improvements in clinical indicators such as calculus index (CIN), periodontal pocket depth and bleeding on probing are observed, the additional impact of Omega-3 has not been shown to be statistically significant. The variability in results may be due to differences in study designs, doses administered, and sample sizes, which limits the ability to establish a clear benefit of Omega-3 on these specific parameters.
