tissue
-Also deals w/ prevention of calculus
Rationale for plaque control
-Identification of microbial plaque as primary etiologic agent for periodontal disease
-Good supra-gingival plaque control helps in controlling growth and composition of
subgingival plaque
Increases plaque formation
-Sugary or starchy foods/drinks
-Dry mouth
-Head and neck radiation
-Smoking
Dental biofilm
-Dense nonmineralized complex of colonies
-Adheres to acquired pellicle and hence to teeth, calculus, fixed and removable
restorations
,-Over 600 distinct microbial species
Formation of plaque
-Acquired pellicle formation
-Initial adhesion
-Coaggregation
-Maturation and diffusion
Disclosing solutions
-Plaque disclosure tool
-Patient education tool
-Stain old plaque blue/purple
-Stain new plaque red/pink
Bristle materials
-natural bristles from hogs
-activated charcoal infused bristles
-artificial filaments from nylon
Natural boar bristles

-claim to be less abrasive than nylon bristles but retain bacteria more so than nylon
bristles
***
Charcoal brushes
-Bristles made with fine grain powder obtained by oxidizing coal, olive pits, coconut

-Place at gingival margin, 45-degree angle to the long axis of teeth
, -Gentle, vibratory pressure, short back and forth motion without dislodging bristles.
-This forces tips in the sulcus as well as in embrasure
-Firm pressure to the gingiva
Charters technique
-Opposite to Bass
-Held perpendicular to long axis of teeth
-Deflect to occlusal surface
Indicated in post surgical healing phase so as not to damage attachment apparatus
Modified stillman technique
Same as roll technique
Angle at 45 degrees and point overlaps the facial gingiva
Head is then just rolled occlusally
Following periodontal surgery to treat gingiva recession
Floss
Indicated interdentally for Plaque removal
Made of nylon filaments
Waxed, unwaxed, thick, thin, flavored
Choice of floss is dependant on patient dexterity, tightness of contacts and roughness of
proximal surfaces
-Recommended based on ease of use and personal preference
Superfloss
-For cleaning around and implant as well as dental bridges
Proxy brush
-More effective in concavities of the root surface than floss
