- Public TitleInterdental brush and waterflosser on gingival bleeding and gingival abrasions. A 4 weeks randomized clinical trial.
- Scientific TitleThe effect of an interdental brush and a water flosser on gingival bleeding and gingival abrasions. A 4 weeks randomized clinical trial.
- ACRONYMWATER
- hypothesisTo assess the effect of the commercially available Water Flosser compared to interdental brushes evaluating gingival bleeding and gingival abrasions in a group of systemically healthy participants with gingivitis but without periodontitis.
- Healt Condition(s) or Problem(s) studiedGingivitis, Gingival abrasion
- Inclusion criteria- Male and female
- Age 18-65 years
- Right handed brusher and writer
- Classified as systemically healthy
- Non-smokers (Lie et al. 1998) definition non-smoker: <1 cigarette every day for at least one year
-Moderate gingivitis (level of gingival bleeding assessed BOPP ; 50%)
- Minimum of 20 natural teeth, at least 5 evaluable in each quadrant available
- Buccal accessible interdental spaces to apply the interdental brush
-The interdental brushes must fit between at least 4 spaces per quadrant when approached buccally, of these 2 should be interdental spaces involving at least two spaces of the molar area.
- The other 2 spaces can be between the pre-molars, cuspid and incisors.

- PublicationsN/A
- Brief summaryThe toothbrush does not adequately reach the interproximal surfaces of the teeth. As gingivitis and periodontitis are usually more pronounced in the interdental areas than on the oral or facial surfaces in susceptible patients. The rationale is to determine the effectiveness of product Water Flosser with water and interdental brush on gingival bleeding and gingival abrasion and to evaluate subjects’ attitudes towards the used products in this study.
