Evaluation of Plaque Removal Efficacy & Patient Acceptability of Knotted Floss Technique in Type II Gingival Embrasures

The subjects use the knotted floss technique. In this modification of conventional flossing technique, a knot is tied in the floss at any distance in the middle third of the floss length. The floss is inserted past the interdental contact point by the conventional finger flossing technique in the non-knotted area and then during the 'to and fro movement' on the tooth surface cervical to contact point, the knotted area is engaged through the embrasure (Gomes et al 2016)

"The subject will wrap the floss around their middle or index finger and gently slide the floss between the teeth and move it along the gum margin, curved into C shape. After this, they will have to move the floss up and down several times between each tooth without using excessive pressure, finally allowing it out through embrasure."

The subject will gently insert the interdental brush into the interdental area with an inclination akin to the angle of the interdental gums (gingiva), and perform to and fro buccal to lingual movements and a little apico-coronal movement such that the gingiva is not impinged, and finally removing the brush out buccally.
