Study Notes

Halitosis: Definition and Types

Halitosis (bad breath) is an unpleasant odor originating from the oral cavity or extraoral sources.
Classified into:
- Genuine halitosis: Objectively confirmed odor with a clinical basis.
- Pseudohalitosis: Patients believe they have bad breath, but there is no clinical evidence.
- Halitophobia: Persistent, irrational fear of having bad breath with no objective evidence.

Causes of Halitosis

Oral causes:
- Bacteria on the tongue: The primary source in most cases, producing volatile sulfur compounds (VSCs).
- Periodontal disease: Inflammation and infection of the gums, leading to VSC production.
- Poor oral hygiene: Inadequate brushing and flossing allow bacteria to thrive.
Extra-oral causes:
- Systemic conditions: Including respiratory infections, gastrointestinal disorders, metabolic diseases, and certain medications.

Diagnosis of Halitosis

Organoleptic measurement: Clinician smells the patient's breath and rates the odor directly.
Gas Chromatography: Detects specific VSCs in breath, providing a quantitative measure.
Portable Sulfide Monitors: Measure VSC levels in the mouth, but less specific than gas chromatography.
Self-Assessment Methods: Smelling floss or licking the wrist.

Management of Halitosis

Oral Hygiene:
- Regular brushing and flossing, especially targeting the tongue.
- Mouthwashes and tongue scrapers reduce bacterial load.
Professional Dental Care:
- Treatment of periodontal disease and regular check-ups.
Diet and Lifestyle Changes:
- Avoiding foods and habits that worsen bad breath, such as smoking.
Treatment of Underlying Conditions:
- Managing systemic issues when halitosis has an extra-oral cause.

Prevalence of Halitosis

Halitosis is one of the most common reasons for dental consultations.
Up to 50% of the population may experience halitosis, with prevalence rates varying based on evaluation methods.

Volatile Sulfur Compounds (VSCs)

Primary compounds causing halitosis are VSCs, including:
- Hydrogen sulfide.
- Methyl mercaptan.
- Dimethyl sulfide.
Other contributing compounds:
- Aromatic compounds: Indole and skatole.
- Organic acids: Acetic acid, propionic acid.
- Amines: Cadaverine, putrescine.

Treatment Approaches

Primary goal: Reduce bacterial biofilm, mainly on the tongue and periodontal structures.
Self-performed biofilm control:
- Use of a soft toothbrush twice a day, interdental cleaning, and tongue scraping.
Professional biofilm control:
- Scaling, root planing, and oral hygiene education.
Adjunctive use of mouth rinses:
- Zinc-based or chlorhexidine (CHX) mouth rinses reduce VSCs, though long-term CHX use may cause side effects (e.g., staining).
Probiotics: Emerging evidence suggests probiotics may help in managing intra-oral halitosis and periodontitis.

Practical Considerations for Healthcare Providers

Dentists and Dental Hygienists:
- Play a primary role in initial diagnosis and management.
- Employ a step-wise approach to manage intra-oral halitosis, addressing oral hygiene and, if needed, recommending mouth rinses.
Other Medical Practitioners:
- Increased awareness and knowledge about halitosis among non-dental HCPs can help in referrals and better patient outcomes.
- Collaborative practice, especially with ENT specialists, is essential for cases where halitosis has an extra-oral cause.

Public Awareness and Patient Education

Many patients do not understand that halitosis is mainly of oral origin.
Education about the importance of oral hygiene, including tongue cleaning, is critical.
Addressing halitosis openly can reduce stigma and improve patients' quality of life.

Key Takeaways for Healthcare Professionals

Intra-oral halitosis constitutes 90% of cases and is usually due to dental or tongue biofilm.
Volatile sulfur compounds are primary odorants in intra-oral halitosis.
Diagnostic Methods: Organoleptic testing and VSC measurement are standard.
Treatment: Emphasizes mechanical cleaning (e.g., tongue scraping) and adjunctive mouth rinses.
Collaboration among healthcare providers enhances diagnosis and treatment.
