About this trial
This is a study to evaluate the safety and the efficacy of an electric flosser (interproximal cleaning aid), when used with a manual toothbrush, on gingivitis and dental plaque removal.

Trial outcomes
Primary outcomes
Reduction from Baseline in proximal Modified Gingival Index (MGI) scores at Day 30
Modified Gingival Index (MGI) is a noninvasive, visual assessment of gingival inflammation. Each tooth will be scored in six areas (disto-buccal, mid-buccal and mesio-buccal, disto-lingual, mid-lingual and mesio-lingual) of all scorable teeth using a scale of 0 - 4: 0 = Normal (absence of inflammation), 1 = Mild inflammation (slight change in color, little change in texture) of any portion of the marginal or papillary gingival unit, 2 = Mild inflammation of the entire gingival unit, 3 = Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit, 4 = Severe inflammation (marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration) of the gingival unit.
Reduction from Baseline in proximal Bleeding on Probing (BOP) at Day 30
Each of six gingival areas (disto-buccal, mid-buccal and mesio-buccal, disto-lingual, mid-lingual and mesio-lingual) of the scorable teeth will be probed in a similar manner, recording the number of gingival units which bleed within 30 seconds, according to the following scale: 0 = absence of bleeding 1 = bleeding observed
Change from pre-cleaning to post-cleaning proximal Rustogi Modified Navy Plaque Index (RMNPI) Scores at Day 30
A red disclosing solution will be used to make plaque visible and improve scoring accuracy. Plaque will be quantified on nine sites per facial and lingual tooth surface. Each tooth surface will be divided into 9 sites, for a total of 18 sites per tooth (A to I facial with 9 sites and lingual with 9 sites); A to C along gingival margin; D to F directly above A to C (D and F being proximal areas); G to H across middle of tooth; and I covered incisal coverage. Plaque will be scored as 0 = Absent or 1 = Present in each area. A mean plaque index (RMNPI) will be calculated for each participant on a whole-mouth basis (areas A-I) and separately for the gingival margin (areas A, B, C) and proximal regions (areas D, F).
Secondary outcomes
Reduction from Baseline in MGI Proximal, Gumline and Whole Mouth scores at Day 15
Modified Gingival Index (MGI) is a noninvasive, visual assessment of gingival inflammation. Each tooth will be scored in six areas (disto-buccal, mid-buccal and mesio-buccal, disto-lingual, mid-lingual and mesio-lingual) of all scorable teeth using a scale of 0 - 4: 0 = Normal (absence of inflammation), 1 = Mild inflammation (slight change in color, little change in texture) of any portion of the marginal or papillary gingival unit, 2 = Mild inflammation of the entire gingival unit, 3 = Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit, 4 = Severe inflammation (marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration) of the gingival unit.
Reduction in Bleeding on Probing (BOP) proximal, gumline and whole mouth scores at Day 15
