Mouthwashes Module: Founda0ons for Clinical Skills and Prac0ce Tutor: Rhona Mann Aim: To gain an insight into the range of mouthwashes and their poten3al role in oral health. 3 Learning Outcomes Acknowledge the range of the various constituents found in mouthwashes. Appreciate the potential benefits of the constituents on patient’s oral health. Have an understanding of the potential disadvantages of certain constituents on patient’s oral health. Be able to analyse the information gained in order to advise patient’s accordingly.  GDC Learning outcomes 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, 6.3 4 6 What is a mouthwash?

When there is oral ulceration and/or certain oral conditions e.g. Lichen planus, Aphthous ulcers. After oral surgery. Xerostomia sufferers. Caries control (Fluoride component) At a different time to brushing Cosmetic: Fresh taste, fresh breath Can you think of anything else? ‘x 9 So what are the general constituents of a mouthwash? Water Alcohol (acting mainly as a preservative) Flavouring Colouring Sweeteners Active Ingredients ………we will discuss these in more detail Ac0ve Ingredients 1 1 As the consumer, what are you thinking?

What does the patient need? Can you justify it? 1 3 Actions of Active Ingredients 1 4 Oxygenating agents Their action is as a cleansing effervescent, introduction of O2 E.g. Sodium Perborate, Hydrogen Peroxide. Will have some antibacterial effect on anaerobic bacteria but are not broad spectrum. What will the bubbles do? Cleanses periodontal pockets 1 5 Astringents Tissue shrinkage Minor role Slight shrinking of soft tissues to certain extent Stingy effect and taste E.g. Zinc Chloride, Zinc Acetate, Citric acids Google images 2021 1 6 Anodynes Help alleviate pain e.g. Phenol derivatives, Essential oils images 2021Google 1 7 Buffering Agents Reduce acidity, reduce soreness e.g Sodium Perborate, Sodium Bicarbonate Google images 2021 1 8 Deodorising agents Masking underlying problem May help in short term but not long term solution Neutralize odours from e.g decomposing food Example: Chlorine Dioxide Google images 2021 Challenge with these products?  Fluoride The addition of Fluoride in mouthwashes has the benefit of caries prevention, prevention and management of demineralisation, patients with certain conditions such as Xerostomia and dental sensitivity. Amounts vary and certain products e.g. Duraphat Google images 2021 Mouthwash contain a higher percentage. Refer to Fluoride and tooth surface lecture 2 0 Pain relief There are products (for example ELUDRIL) that not only contain an an3microbial (in the case of Eludril this is Chlorhexidine) but also contain a mild local anaesthe0c. In Eludril this is CHLOROBUTANOL 0.5% This makes it poten3ally useful in the management of certain oral condi3ons that are painful, e.g. Apthous ulcers Antimicrobials Bisbiguanides (e.g. Chlorhexidine ) Bispyridines (e.g. Ocetedine) Pyrimidines (e.g. Hexetidine) Halogens (e.g. Fluoride and Iodine) Phenols/Phenolic : Phenol, Thymol Quaternary Ammonium Compounds (eg Cetylpyridium Chloride) Herbal: Sanguinarine Oxidising agents Fluoride 21 General considerations Active ingredient Indication (when would you recommend it?) Duration of use Side effects Cost Access Google images 2021 2 3 Chlorhexidene Chlorhexidine is broad spectrum Antimicrobial Well evidenced usage comba3ng periodontal disease related bacteria Absorbed onto ALL oral surfaces Good substan0vity….released slowly and stays ac3ve for up to 24 hours, binding onto surfaces, pellicle, etc 2 4 Effects of Chlorhexidine Bactericidal – High Concentration Bacteriostatic – Low Concentration Causes cell lysis Causes cell content leakage loss of Incorporates into bacteria potassium & phosphates Extreme leakage loss of potassium Reduces replication & phosphates But can recover Impacts cell membrane & thus lysis 2 5 Chlorhexidine – Indications of use Gingvitis Periodontal disease Case to case basis If interferes with patients oral hygiene 2 6 Potential side effects Staining can be a significant problem and increases with prolonged use Taste can be disturbed Reported cases of tongue discomfort and burning Oral Desquamation Swelling of the Parotid ( rare side effect) Can effect certain constituents of toothpastes Google images 2021 2 7 What is available in the Corsodyl mouthwash range? Daily range contains Chlorhexidine 0.06% GSK Website 2021 2 8 Corsodyl original contains 0.2% Chlorhexidine Gluconate GSK website 2021 2 9 Phenolic compounds Not as effective as Chlorhexidine Poor oral retention Has some anti inflammatory effects Reduction of plaque by up to 30% Works by altering the bacterial cell wall Works in association with essential oils Common products – Listerine Google images 2021 3 0 Essential Oils Menthol , a natural antibacterial Eucalyptus , a natural anti inflammatory Thymol, a natural antiseptic Google images 2021 Tend to be incorporated into a phenolic compound in many products. 3 1 Triclosan Triclosan is a derivative of Phenol and is used in toothpastes but can also be found in some mouthwashes. Has a broad spectrum anti bacterial effect as well as some anti inflammatory effects.

Dentyl is an oil &water based product mixed before use. Lifts and absorbs bacteria & debris( including food particles, epithelial cells etc) Google images 2021 3 3 Hexetidine………… ORALDENE antimicrobial found in e.g. Oraldene Broad sprecturm Google images 2021 Sanguinarine Plant based, appears to have effective anti plaque properties Google images 2021 34 Oxygena0ng agents Eg Hydrogen peroxide Beneficial in certain conditions, for example AUG as it inhibits anaerobic bacteria.
