Adjuncts For Periodontal Treatment Flashcards
What factors determine toothpaste abrasiveness?
Particle hardness, size, shape, concentration, viscosity, and presence of soluble ingredients like surfactants (reduce) or polyphosphates. (reduce)
What is the maximum recommended RDA for toothpaste?
Relative Dentine Abrasivity (RDA)
250 (ADA standard)
above causes damage
What is the preferred REA value for enamel protection?
Relative Enamel Abrasivity (REA)
Less than 40.
Which fluoride formulation has significant anti-plaque and anti-gingivitis effects but may cause staining?
Stannous fluoride (SnF2)
Which ingredient provides anti-plaque and anti-gingivitis effects with no side effects?
Sodium bicarbonate
Why is Triclosan limited in use despite its anti-plaque properties?
Health concerns.
antimicrobial resistance
What is the main benefit of calcium sodium phosphosilicate (CSPS/Novamin)?
Short-term anti-caries effect.
occludes dentinal tubules
Which ingredients are beneficial for dentine hypersensitivity?
SnF2, arginine, potassium nitrate, strontium chloride, hydroxyapatite, and CSPS (Novamin)
How does SnF2 help in dentine hypersensitivity?
a protective layer over exposed dentine.
Which fluoride formulations are effective in reducing enamel loss due to erosion and abrasion?
NaF and SnF2.
What are the main concerns with charcoal-based whitening toothpastes?
High abrasiveness.
What is the effect of peroxide on whitening?
Effective in stain removal but may decrease tooth microhardness.
How does sodium bicarbonate improve stain removal?
Its efficacy increases significantly when combined with 1% hydrogen peroxide.
What role do phosphates play in whitening?
Help remove extrinsic stains with no reported side effects.
What are key active ingredients in mouthwashes?
Chlorhexidine (CHX): Gold standard in short-term plaque control.
Hydrogen peroxide (H₂O₂): Oxidizing effect, stain reduction.
Essential oils (e.g., thymol, menthol): Anti-inflammatory.
Cetylpyridinium chloride (CPC): Broad-spectrum antimicrobial.
What are the European Federation of Periodontology (EFP) recommendations for mouthwashes in periodontitis patients?
Use CHX, essential oils, or CPC-containing products for gingival inflammation control.
What is the recommended dosage of CHX mouthwash?
0.2%, 10ml, twice a day, held in the mouth for one minute.
How long should a patient wait after using CHX before eating or drinking?
30 minutes.
What is the CHX concentration in Corsodyl Daily mouthwash?
0.06%
for daily use
What are potential side effects of CHX?
Tooth/tongue staining (common).
Taste alteration.
Allergic reactions (rare).
Parotid gland swelling (rare).
Does Corsodyl toothpaste contain CHX?
No, it contains sodium bicarbonate instead.
