Evaluation of Plaque Removal Efficacy and Patient Acceptability of Knotted Floss Technique in Type I Gingival Embrasures

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)
