Abstract
Background and aims. Gingivitis is a common periodontal disease which involves different parts of gingiva to various
degrees and severity. Unsaturated fatty acids have the potential to decrease the inflammation and can be effective in
treatment of gingivitis. The aim of this study was to evaluate the effect of omega-3 unsaturated fatty acids in treatment of
moderate gingivitis.
Materials and methods. This evaluation is a double blind clinical trial which was performed on 50 patients, 20 to 40
years old, with moderate gingivitis. Patient with same oral hygiene were assessed during 28 days and divided in to two
groups. The test group received omega3 unsaturated fatty acids and the control group got the placebo for 10 days. Gingival
Index (GI; Loe & Silness) and bleeding On Probing (BOP; Barnet) were recorded on the ramfjord teeth in the day of the
prescription and the 5, 10 and 20 days after that. Data were analyzed by Friedman and Man-Whitney statistical tests.
Results. The indices showed decrease in both groups significantly (p<0.0001), but the omega3 unsaturated fatty acid was
more effective (GI and BOP =p<0.0001) compared to the placebo group.
Conclusion. Results of present study showed that good oral hygiene and using omega-3 unsaturated fatty acid are
effective in treatment of gingivitis
