Omega-3 and aspirin combination matches antibiotics in treating severe gum disease

A yearlong clinical study suggests modulating inflammation could offer a viable alternative to antibiotic treatments for periodontitis.

The short version

A study of 109 patients with advanced periodontitis found that a daily regimen of omega-3 and low-dose aspirin was about as effective as a standard course of antibiotics.
Both the supplement group and the antibiotic group achieved an approximate 58% success rate in reducing deep periodontal pockets to four or fewer.
The findings could eventually help reduce reliance on antibiotics, though researchers caution that more diverse clinical trials are required before the combination can routinely replace them.

The yearlong clinical study involved 109 patients with advanced periodontitis divided into four treatment groups, all of whom underwent standard scaling.[ScienceDaily]
The target goal of having four or fewer remaining deep pockets was met by 57.7% of patients receiving three grams of omega-3 daily and low-dose aspirin for six months, compared to 58% of patients taking the antibiotics metronidazole and amoxicillin for 14 days.[ScienceDaily]
Only 23.1% of patients in the control group, who received scaling alongside placebos, met the clinical goal.[ScienceDaily]
Combining antibiotics with the omega-3 and aspirin regimen yielded no additional clinical benefits over either treatment strategy on its own.[ScienceDaily]
The research was a collaborative effort by scientists from Albert Einstein Israelite Hospital, Guarulhos University, University of Taubaté, the Ribeirão Preto School of Dentistry at USP, and Harvard University, and was published in the Journal of Periodontology.[ScienceDaily]

The study only included patients without significant systemic or oral diseases, leaving it unclear whether these findings will hold true for broader, more diverse patient populations.[ScienceDaily]
Researchers are still conducting microbiological analyses to determine exactly how the treatments alter bacterial species and affect the body's inflammatory response inside the periodontal pockets.[ScienceDaily]
