The Effect of Sonicare AirFloss + MTB Treatment Versus the Control Group [ Time Frame: Four Months ]
The primary objective of the study is to compare the effect of Sonicare AirFloss + MTB treatment versus the Control Group on gingival inflammation (as measure by number of bleeding sites, and reduction in MGI) after four weeks of use.

Philips AirFlosser Study
An Investigation of the Effects of a Oral Hygiene Regimen in Irregular Flossers on Gingivitis and Plaque

In the current study, Sonicare AirFloss (AF) will be used in combination with a Manual Toothbrush (MTB) in a population of manual toothbrush users who are irregular flossers and who exhibit signs of moderate gingivitis. The alternate test arm will be allocated to a No Intervention group and will be given no test products or instruction other than to change none of their typical at home oral hygiene habits.

The aim of this study is to investigate how an AF and MTB oral hygiene intervention will affect a population of irregular flossers using the residual protein concentration method as an interproximal plaque efficacy assessment. Gingivitis reduction will be assessed using the Modified Gingival Index (MGI) and Gingival Bleeding Index (GBI) indices
