Study Notes
Mouthwashes Overview
- Mouthwashes are chemotherapeutic agents, supplemental to a patient's home oral care routine.
- Their aim is to provide insight into their various components and potential roles in oral health.
Learning Outcomes
- Understand the range of constituents found in mouthwashes.
- Recognize the potential benefits of constituents on oral health.
- Identify potential disadvantages of certain constituents on oral health.
- Apply knowledge to advise patients appropriately.
- Accomplish specified GDC learning outcomes.
What is a Mouthwash?
- A mouthwash is a chemical agent, not a replacement for mechanical plaque removal.
- It's used as an adjunct to a patient's home-care system.
When Mouthwashes are Recommended
- For individuals with difficulty performing adequate oral hygiene due to medical, physical, or mental limitations.
- In cases of oral ulceration or related conditions (e.g., lichen planus, aphthous ulcers).
- Post-oral surgery.
- For patients experiencing xerostomia.
- For caries control (fluoride component).
- For cosmetic purposes (fresh taste, breath).
General Constituents of Mouthwash
- Water
- Alcohol (preservative)
- Flavouring
- Colouring
- Sweeteners
- Active ingredients
Actions of Active Ingredients
- Antimicrobial
- Physical plaque removal
- Astringent
- Deodorizing
- Buffering agents
- Anodynes
- Crystalline impact
Oxygenating Agents
- Cleansing and effervescent, introducing oxygen (O2).
- Examples: Sodium Perborate, Hydrogen Peroxide.
- Primarily effective for anaerobic bacteria.
Astringents
- Tissue shrinkage.
- Examples: Zinc Chloride, Zinc Acetate, Citric acid.
Anodynes
- Pain relief.
- Examples: Phenol derivatives, essential oils.
Buffering Agents
- Reduce acidity and soreness.
- Examples: Sodium Perborate, Sodium Bicarbonate.
Deodorizing Agents
- Neutralize odors from decomposing food.
- Examples: Chlorine Dioxide.
Fluoride
- Added to mouthwashes to prevent caries and manage demineralization.
- Beneficial for patients with conditions such as xerostomia and dental sensitivity.
- Concentrations vary between products (Duraphat higher).
Pain Relief
- Some products contain an antimicrobial (e.g., chlorhexidine in Eludril) and a local anesthetic (e.g., chlorobutanol 0.5% in Eludril).
- This can be beneficial for managing certain painful oral conditions, such as aphthous ulcers.
Antimicrobials
- Various types are used, including bisbiguanides (e.g., chlorhexidine), bispyridines (e.g., ocetidine), pyrimidines (e.g., hexetidine), halogens (e.g., fluoride, iodine), phenols (e.g., phenol, thymol), quaternary ammonium compounds (e.g., cetylpyridinium chloride), herbal (sanguinarine), and oxidizing agents.
General Considerations when recommending mouthwash
- Active ingredient
- Indication (when to recommend)
- Duration of Use
- Side effects
- Cost
- Accessibility
Chlorhexidine
-
Broad-spectrum antimicrobial.
-
Well-studied for combating periodontal disease-related bacteria.
-
Absorbed onto all oral surfaces.
-
Good substantivity (released slowly).
-
Stays active for up to 24 hours
-
Bactericidal at high concentrations, bacteriostatic at low concentrations.
-
Used for gingival conditions, compromised oral hygiene, and oral conditions.
-
Potential Side Effects include staining, altered taste, oral discomfort, and parotid swelling.
Corsodyl Mouthwash
- Contains Chlorhexidine 0.06% (daily range) & Chlorhexidine Gluconate 0.2% (original).
Phenolic Compounds
- Not as effective as Chlorhexidine.
- Poor oral retention.
- Some anti-inflammatory effects & Plaque reduction (up to 30%).
- Works in association with essential oils.
- Examples: Listerine mouthwash.
Essential Oils
- Naturally occurring antibacterials, anti-inflammatories, and antiseptics.
- Examples: menthol, eucalyptus, thymol.
- Often incorporated into phenolic compounds.
Triclosan
- Phenol derivative, effective antimicrobial and anti-inflammatory agent.
- Used in mouthwashes, toothpastes, and other products.
- Safety/toxicity concerns exist.
Cetylpyridinium Chloride
- Moderate plaque inhibitor.
- Oral retention similar to Chlorhexidine, however, less effective at preventing gingivitis.
- Found in Dentyl.
Hexetidine
- Antimicrobial.
- Found in mouthwashes like Oraldene.
Sanguinarine
- Plant-based, appears to have anti-plaque properties.
- Found in some mouthwashes.
Oxygenating Agents
- Beneficial in certain conditions (e.g., AUG) by inhibiting anaerobic bacteria.
- Eg: Hydrogen Peroxide
Mouthwash and Alcohol Content
- Many contain alcohol (up to 26%).
- Accidental or intentional ingestion is a concern.
- Potential for soft tissue discomfort and interaction with restorative materials.
- Alcohol-free options available.
