Purpose: Desquamative gingivitis (DG) is characterized by desquamative erosion, edematous erythema, and vesicle formation on the gingiva. Because of its prevalence in women during the pre- and postmenopausal period, its potential association with female hormones has been suggested. Equol is a soy isoflavone metabolite with a chemical structure similar to estrogen. Scientific evidence suggests that equol helps in alleviating menopausal symptoms. This study evaluated the clinical effect of a 12-month equol supplementation as a substitute for estrogen to alleviate DG symptoms.
Methods: The study enrolled 16 women with DG who regularly visited Nihon University School of Dentistry Dental Hospital. Urinary equol levels, periodontal tissue examination, O’Leary’s plaque control record, stimulated saliva flow rate, and gingival pain-related questionnaires were evaluated before and after the 12-month daily intake of 10 mg equol supplement.
Results: Equol supplementation led to a statistically significant improvement in bleeding on probing, visual findings, and reductions in the frequency and severity of gingival pain.
Conclusion: Urinary equol testing and equol supplementation may be novel treatment options for female patients with DG.
