Effect of omega-3 and vitamin E supplementation on dry mouth in patients with Sjögren's syndrome.

Abstract

To determine whether omega-3 (n-3) increases saliva production in patients with Sjögren's syndrome, 61 patients with Sjögren's received either wheat germ oil (n = 23) or n-3 supplement (TheraTears Nutrition®) (n = 38) in a prospective, randomized, double-masked trial. The outcomes assessed were salivary secretion and markers for oral inflammation. The differences between the n-3 group and wheat germ oil group were not statistically significant for either unstimulated (US) or stimulated (SS) salivary secretion (p= 0.38 and p= 0.346, respectively) nor for the number of sites with probing depth (PD) ≥ 4 mm (p= 0.834). In this pilot study, supplementation with n-3 was not found to be significantly better than wheat germ oil in stimulating saliva production in patients with Sjögren's syndrome.
