To compare the efficacy of Waterpik® Complete Care (Water Flosser and Sonic Toothbrush) vs. Sonicare® FlexCare on gingival bleeding, gingivitis and plaque removal.
One hundred and forty subjects were enrolled in this 4 week, randomized, single blind, clinical study. Subjects were assigned to one of four groups; Group 1 used a Waterpik® Complete Care — combination Water Flosser and Sonic Toothbrush, Group 2 used a Waterpik® Sonic Toothbrush only, Group 3 used a Sonicare® FlexCare only, and Group 4 used an ADA standard manual toothbrush. Bleeding on Probing (BOP), Modified Gingival Index (MGI) and Rustogi Modified Navy Plaque Index (RMNPI) were measured at 14 days and 28 days.
At 4 weeks, Waterpik® Complete Care was significantly more effective than Sonicare® FlexCare on all measures; 70% better for Gingival Bleeding, 48% better for Gingivitis, and 52% better for Plaque Removal. At 4 weeks, Waterpik® Complete Care was also significantly more effective than a manual toothbrush on all measures; 159% better for Gingival Bleeding; 135% better for Gingivitis, and 134% better for Plaque Removal.
The Waterpik® Complete Care regimen is up to 70% more effective than Sonicare® FlexCare and up to 159% more effective than a manual toothbrush for improving gingival health.
