•Plaque control is the regular removal of
microbial plaque and the prevention of its
accumulation on the teeth and adjacent
gingival surfaces.
•Microbial plaque is the major etiology of
periodontal diseases
•Patient cooperation in daily plaque removal is
critical to long-term success of all periodontal
treatment.

• In 1965, Löe et al conducted the classic study-
relationship between plaque accumulation and
the development of experimental gingivitis in
humans.
•Stopped brushing and other plaque control
procedures, resulting in the development of
gingivitis in every person within 7 to 21 days.
•The composition of the plaque bacteria also
shifted so that gram negative organisms
predominated, and these changes were shown

•Plaque formation begins on the interproximal
surfaces where the toothbrush does not reach.
•Masses of plaque first develop in the molar and
premolar areas, followed by the proximal
surfaces of the anterior teeth and the facial
surfaces of the molars and premolars.
•Patients consistently leave more plaque on the
posterior teeth than the anterior teeth, with
interproximal surfaces retaining the highest
amounts of plaque, exactly the places in which

TOOTH BRUSH
•Chewstick as tooth brush by Chinese about 1600BC.
•Hippocrates given commentaries on removing
deposits from teeth(460-377BC)
• First bristle toothbrush was introduced by Chinese in
sixteenth century.
![Page 7: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/7.jpg)
•Oral health- regular personal plaque removal.
•Mechanical removal of oral biofilm via toothbrushing
is the most widely accepted.
• The most commonly used device-the manual
toothbrush,
•Well designed to remove plaque from the facial,
lingual, and occlusal tooth surfaces
![Page 8: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/8.jpg)

• Powered toothbrushes are recommended for:
1. Individuals lacking fine motor skills.
2. Small children or handicapped or hospitalized patients
3. Patients with orthodontic appliances.
4. Patients who prefer them.
![Page 13: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/13.jpg)
Various types of motions used in powered toothbrushes
are:

2. Circular.
3. Elliptical or combination.
![Page 14: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/14.jpg)
DENTIFRICES
• These are the aids for cleaning and polishing of teeth
surfaces.
• They are used in the form of powders, pastes and gels.
Composition:
•Abrasives: CaCO3, Ca3 (PO4)2
•Humectants: glycerine, sorbitol, mannitol, propylene
glycol
• Thickening agents: sodium carboxy-methyl cellulose
![Page 15: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/15.jpg)

![Page 16: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/16.jpg)
INTERDENTAL CLEANING AIDS
• Toothbrush does not completely remove interdental
plaque
•Dental floss and interdental cleaners such as wooden
or plastic tips and interdental brushes.
![Page 17: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/17.jpg)
Factors determining the selection of interdental aids:
• Type 1: The interdental papilla fills up the embrasure.
Dental floss is advised
• Type 2: Moderate papillary recession, miniature
interdental brushes and wood tips are recommended.
• Type 3: Complete loss of papilla (seen in diastema).
Unitufted brushes are recommended.
![Page 18: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/18.jpg)
DENTAL FLOSS
•Most commonly recommended method of removing
plaque.
•Made from nylon filaments or plastic monofilaments,
and can be waxed, unwaxed, thick, thin, and even
flavored.
•Unwaxed floss is preferred over waxed.
![Page 19: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/19.jpg)
METHOD
Spool method:
• 12-18 inches taken
•About 4 inches wound around middle finger
• 1-2 inches held tightly between index fingers.
![Page 20: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/20.jpg)
![Page 21: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/21.jpg)
Loop method:
• Loop of floss is made about 12-18 inches with 3
knots.
• Passed through contact area, firm back and forth
motion.
• Lack of dexterity, old age.
Floss holders are also available.
![Page 22: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/22.jpg)
INTERDENTAL BRUSHES
• Interdental brushes are available in various sizes and
shapes.
•Conical or tapered (like an ever- green tree)
•Designed to be inserted into a plastic, reusable handle
that is angled to facilitate interproximal adaptation.
• Interproximal brushes are equal to or more effective
than floss for plaque biofilm removal.
![Page 23: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/23.jpg)
• Insert bristles into embrasure at a 90-degree angle to
tooth surface (long axis of the tooth).
•Move brush using in and out motion from facial
and/or lingual surfaces of appropriate area.
![Page 24: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/24.jpg)
WOODEN TIPS
•Manufactured from orange wood
• Triangular in cross section.
• Base of the triangle oriented towards the gingiva
• Repeatedly moved in and out of the embrasure.
• Restricted to facial aspects of anterior teeth.
![Page 25: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/25.jpg)
UNITUFTED BRUSH
• Small brush with single, short tuft of bristles.
• Indicated in type 2 and type 3 embrasures.
•Used with a rotatory motion similar to Bass technique.
![Page 26: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/26.jpg)
GINGIVAL MASSAGE
•Massaging the gingiva with a rubber tip or other device
can lead to:
1. improved circulation
2. increased keratinization
3.epithelial thickening.
• Place side of rubbertip interdentally and slightly
pointing coronally(45˚), Move in and out with a slow
stroke, rubbing the tip against the teeth.
![Page 27: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/27.jpg)
WATER IRRIGATION DEVICES
• Valuable supplement for mechanical plaque control
• Removes unattached plaque and debris.
• Built in pump and reservoir
•Also used with antimicrobial agents.
![Page 28: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/28.jpg)
CHEMICAL PLAQUE CONTROL
• Ideal adjunct to mechanical plaque control that
includes:
1.Prescription chlorhexidine rinse
2.Nonprescription essential oil rinse
3.Antibiotics
4.Quaternary ammonium compounds
5.Enzymes
![Page 29: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/29.jpg)
CHLORHEXIDINE
•Cationic Bisbiguanide.
• Superior antiplaque activity – ‘Substantivity’
• Low concentration: bacteriostatic
•High concentration: bactericidal
• Single rinse: antibacterial activity in saliva for about 5
hours
![Page 30: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/30.jpg)
• Prevents pellicle formation- blocking acidic groups on
salivary glycoprotein reducing glycoprotein adsorption
on tooth surface.
• Prevents adsorption of bacterial cell wall on tooth
surface- binding to the bacteria
• Prevents binding of mature plaque- precipitating
agglutination factors in saliva & displacing calcium
from plaque matrix
![Page 31: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/31.jpg)
NON PRESCRIPTION ESSENTIAL OIL RINSES
• Long history of use and safety
•Demonstrated plaque reductions in long term clinical
studies
• Eg: Thymol, Eucalyptol, Menthol, Methyl salicylate.
• Listerine
![Page 32: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/32.jpg)
ANTIBIOTICS
• Vancomycin, Erythromycin, Niddamycin and
Kanamycin have been used.
• Bacterial resistance and hypersensitivity reactions.
![Page 33: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/33.jpg)
ENZYMES
•Would be able to breakdown already formed matrix of
plaque and calculus
•Certain proteolytic enzymes are bactericidal to
microorganisms.
• Effective when applied topically in the mouth.
• Eg: Mucinase
![Page 34: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/34.jpg)
QUATERNARY AMMONIUM COMPOUNDS
• Effective against developing plaque, predominant
gram +ve organisms.
•+vely charged molecule reacts with –vely charged cell
membrane phosphates, disrupts cell wall of
microorganisms
• Eg: Benzathonium chloride.
![Page 35: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/35.jpg)
OTHER AGENTS
Triclosan:
• Phenol derivative, recently included.
• Broad spectrum of activity against both gram +ve and –ve
bacteria.
• Acts on microbial cytoplasmic membrane, inducing
leakage of cellular constituents, causing bacteriolysis.
• Delays plaque maturation and also inhibits formation of
Prostaglandins and leukotrienes.
![Page 36: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/36.jpg)
Delmopinol:
•Morpholino ethanol derivative
• Interferes with plaque matrix formation and reduces
bacterial adherence.
•Causes weak binding of plaque to tooth surface, thus
aiding in easy removal of plaque by mechanical
procedures
• Pre-brushing mouthrinse.
![Page 37: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/37.jpg)
S.APARNA ET ALJOURNAL OF PERIODONTOLOGY: SEPTEMBER 2012
• The aims of this study are as follows: 1) to evaluate the
antibacterial efficacy of honey against oral bacteria and
compare the same with 0.2% chlorhexidine; and 2) to
compare antiplaque efficacy in vivo with chlorhexidine.
• The in vivo results revealed that plaque formation was
inhibited/reduced by chlorhexidine and honey rinses.
•Concluded that Honey has antibacterial action against
tested oral microorganisms and also has antiplaque
action.
![Page 38: Plaque control](https://reader034.fdocuments.net/reader034/viewer/2022052317/55ac33ee1a28abbb4b8b47bb/html5/thumbnails/38.jpg)
M.P.C. VAN LEEUWEN, D.E. SLOT AND G.A. VAN DER WEIJDENJOURNAL OF PERIODONTOLOGY: FEBRUARY 2011.
• No significant difference with respect to reduction of gingival
inflammation was found between EOMW and chlorhexidine
mouthwash
• In long-term use, the standardized formulation of EOMW
appeared to be a reliable alternative to chlorhexidine
mouthwash with respect to parameters of gingival
inflammation.

CONCLUSION
• Periodontal disease- majority of missing teeth
•Only possible solution to the problem is prevention.
• Proper oral hygiene practices- controls periodontal
disease.
• Patient education.
