A yearlong clinical study conducted by researchers from institutions in Brazil and the United States, including Albert Einstein Israelite Hospital, Guarulhos University, the University of Taubaté, the Ribeirão Preto School of Dentistry at USP, and Harvard University, found that a combination of omega-3 fatty acids and low-dose acetylsalicylic acid (ASA) was nearly as effective as a standard antibiotic regimen in treating severe periodontitis. The study, published in the Journal of Periodontology, involved 109 participants with advanced periodontitis who were divided into four groups: one receiving a placebo, another receiving antibiotics (metronidazole and amoxicillin), a third receiving omega-3 and ASA, and a fourth receiving both antibiotics and the supplement regimen. After one year, approximately 58% of patients treated with antibiotics and 57.7% of those treated with omega-3 and ASA reached the clinical target of having no more than four remaining deep periodontal pockets, compared to only 23.1% in the placebo group. The combination of antibiotics and the supplement regimen did not yield additional benefits over either treatment alone.
The researchers suggest that the omega-3 and ASA combination could offer an alternative treatment for severe periodontitis, particularly for patients who cannot take antibiotics due to allergies or intolerances. This potential alternative is significant in the context of growing concerns about antibiotic resistance, a major global health threat. Omega-3 fatty acids are thought to modulate inflammation differently from conventional anti-inflammatory medications by promoting the production of molecules that help resolve inflammation and promote tissue repair. Low-dose ASA is believed to enhance this effect. The study’s lead authors, dental surgeon Nídia Cristina Castro dos Santos and dental surgeon Magda Feres, noted that the benefits of the omega-3 and ASA regimen persisted even six months after supplementation ceased, indicating a possible longer-lasting impact on the body’s inflammatory response. However, the researchers caution that while the findings are promising, omega-3 and ASA should not yet be considered a routine replacement for antibiotics in treating severe periodontitis, and further studies are needed to confirm the results in more diverse populations and to identify which patients are most likely to benefit from each treatment strategy.
