|Gingivitis||Device: IB = Interdental brush, the intervention Device: DF = Dental floss, the positive control||Phase 3|
|Study Design:||Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Prevention
|Official Title:||Comparison of Inter-dental Brush to Dental Floss for Reduction of Plaque and Bleeding in Areas With Intact Papilla: A Clinical Trial|
- Plaque and bleeding reduction [ Time Frame: 12 weeks ]
- Product preference between dental floss and interdental brush [ Time Frame: 12 weeks ]
|Study Start Date:||August 2008|
|Study Completion Date:||November 2010|
|Primary Completion Date:||November 2010 (Final data collection date for primary outcome measure)|
Active Comparator: 1
Interdental brush (IB), the intervention is a small multi-tufted brush on a wire attached to a long angled handle that is inserted in a horizontal plane between the teeth. The IB is inserted once and removed.

Placebo Comparator: 2
Dental floss (DF), the positive control, is waxed dental floss; nylon covered with a water soluble unflavoured wax to facilitate easier access the contact points of teeth. DF is rubbed against the interproximal surfaces of the teeth 2-4 times on each surface.

To determine if the interdental brush is just as effective at removing plaque and reducing bleeding gums between the teeth as dental floss.
Many people find dental floss difficult to use and thus, do not floss daily to maintain oral health and prevent gum disease. These individuals may find the interdental brush easier to use and may be motivated to use it daily for optimal oral health.
Study subjects will use the dental floss AND the interdental brush for 12 weeks. Plaque and bleeding scores will be measured before the study begins (week 0), mid-way (week 6), and at the end of the 12 weeks. All study subjects receive a teeth cleaning prior to the first measurements and oral hygiene instructions on how to floss and use the interdental brush. Subjects will also answer 4 short questions about their product preference and ease of use.
32 healthy adult volunteers with bleeding gums. To be included in the study, subjects require 8 bleeding sites, 4 areas that can accommodate the interdental brush, dexterity to dental floss, and willingness to come for 4 study visits. Exclusion criteria include smokers because this can affect the bleeding scores; individuals with braces (orthodontia) which affects plaque levels; individuals using chlorhexidine which is a prescription strength mouthwash used to treat moderate to severe gum disease; pregnant women; and those individuals requiring antibiotics prior to dental appointments. Enrolled study subjects receive a teeth cleaning (value $180), $75 for completing the study, and all study related supplies.
