Study Notes

Mouthwashes

  • Mouthwash is a chemotherapeutic agent used as an adjunct to a patient's home care oral regime.
  • The aim of the presentation is to provide insight into the range of mouthwashes and their role in oral health.
  • Learning objectives include: acknowledging the range of constituents in mouthwashes; appreciating the potential benefits of constituents on oral health; understanding potential disadvantages of certain constituents on oral health; analyzing information to advise patients accordingly.
  • GDC learning outcomes are listed as 1.1.1, 1.1.8, 1.2.3, 1.9.1, 1.10.2, 1.10.3, 1.10.4, 1.10.5, 6.1, 6.2, and 6.3.
  • Mouthwashes are not a replacement for mechanical plaque removal.
  • Recommended for those with difficulty with good oral hygiene (medically, physically, or mentally compromised).
  • Recommended for oral ulceration and certain oral conditions like lichen planus, or aphthous ulcers.
  • May be recommended after oral surgery or for those with xerostomia.
  • Also recommended for caries control (fluoride component) and cosmetic purposes (fresh taste, fresh breath).

General Constituents of Mouthwash

  • Water

  • Some antibacterial effect on anaerobic bacteria, but not broad spectrum.

Astringents

  • Tissue shrinkage
  • Examples: Zinc Chloride, Zinc Acetate, Citric acids

Anodynes

  • Help alleviate pain.
  • Examples: Phenol derivatives, Essential oils

Buffering Agents

  • Reduce acidity and soreness.
  • Examples: Sodium Perborate, Sodium Bicarbonate

Deodorising Agents

  • Neutralize odors from decomposing food.
  • Example: Chlorine Dioxide

Fluoride

  • Addition of fluoride in mouthwashes benefits caries prevention and management of demineralization.
  • Patients with conditions like xerostomia and dental sensitivity may benefit.
  • Amounts vary in different products, with some containing a higher percentage (e.g., Duraphat). Refer to the lecture on Fluoride and tooth surface.

Pain Relief

  • Some products, like Eludril, contain both an antimicrobial (like chlorhexidine) and a mild local anesthetic (like chlorobutanol).
  • This combination may be beneficial for managing certain painful oral conditions.

Antimicrobials

  • Bisbiguanides (e.g., chlorhexidine)
  • Bispyridines (e.g., ocetedine)

  • Quaternary Ammonium Compounds (e.g., cetylpyridinium chloride)
  • Herbal (e.g., sanguinarine)
  • Oxidising agents
  • Fluoride

General Considerations

  • Active ingredient
  • Indication for use
  • Duration of use
  • Side effects
  • Cost
  • Access

Chlorhexidine

  • Broad-spectrum antimicrobial.
  • Well-documented use in combating periodontal disease-related bacteria.
  • Absorbed onto all oral surfaces, with good substantivity (released slowly and stays active for up to 24 hours).

Effects of Chlorhexidine

  • Bactericidal (high concentration): cell lysis, incorporates into bacteria, extreme potassium and phosphate leakage, impacts cell membrane.
  • Bacteriostatic (low concentration): cell content leakage, reduces replication, but bacteria can recover.

Chlorhexidine - Indications of Use

  • Gingival conditions
  • Compromised oral hygiene
  • Ulcerations
  • Oral conditions

Potential Side Effects

  • Staining (significantly with prolonged use)
  • Taste disturbances
  • Tongue discomfort/burning
  • Oral Desquamation
  • Parotid swelling (rare side effect)
  • Effects on certain toothpaste constituents

Corsodyl Mouthwash Range

  • Contains chlorhexidine 0.06% (daily range)
  • Contains chlorhexidine gluconate 0.2% (original)

Phenolic Compounds

  • Not as effective as chlorhexidine.
  • Poor oral retention.
  • Has some anti-inflammatory effects.
  • Reduces plaque by up to 30%.
  • Works by altering bacterial cell walls.
  • Works in association with essential oils.
  • Common products: Listerine

Essential Oils

  • Menthol (natural antibacterial)
  • Eucalyptus (natural anti-inflammatory)
  • Thymol (natural antiseptic)
  • Often incorporated into phenolic compounds

Triclosan

  • Derivative of phenol.
  • Used in toothpastes and mouthwashes.
  • Has a broad-spectrum antibacterial effect and some anti-inflammatory effects.
  • Originally used as a hospital scrub in the 1970s.

Cetylpyridinium Chloride

  • Moderate plaque inhibitory effect.
  • Higher initial oral retention and equivalent antibacterial activity to chlorhexidine.
  • Less effective in inhibiting plaque and preventing gingivitis.
  • Found in products like Dentyl (oil and water based).

Hexetidine

  • Antimicrobial found in products like Oraldene.

Sanguinarine

  • Plant-based with effective anti-plaque properties.

Oxygenating Agents (Hydrogen Peroxide)

  • Beneficial in certain conditions, for example AUG, as it inhibits anaerobic bacteria.

Mouthwashes and Alcohol Content

  • Many mouthwashes contain alcohol (up to 26%).
  • Caution is needed if accidentally swallowed
  • Alcohol content can cause soft tissue discomfort and affect some restorative materials.
  • Links to various research articles and papers about mouthwash.
