Study Notes
Halitosis Classification
- Halitosis can be categorized by origin and psychological factors
- Genuine halitosis is further divided into physiologic and pathologic
- Physiologic halitosis is a temporary, non-pathological bad breath
- It often occurs in the morning due to reduced saliva, allowing anaerobic bacteria to produce volatile sulfur compounds (VSCs)
- Other factors can lead to temporary halitosis, like foods with high sulfur content and lifestyle factors like smoking
- Pathologic halitosis originates in the oral cavity
- It accounts for 85% of cases, with causes including oral bacteria in biofilm, periodontal disease, dry mouth increasing VSC production, and extraoral causes such as respiratory, gastrointestinal, or metabolic disorders like GERD, sinusitis, and diabetes
- Pseudohalitosis is a belief of bad breath without objective evidence, linked to psychological or misinterpretation of sensory information
- Halitophobia is the intense, persistent fear of bad breath, requiring psychological intervention to address this fear
Methods to Measure Halitosis
- Various methods, both direct and indirect, are used to diagnose and quantify halitosis
- Direct measurement techniques include organoleptic assessment and portable sulfide monitors
- Organoleptic measurement is a subjective assessment of breath odor using a scale from 0 to 5 (0 no odor, 5 very strong odor)
- Portable sulfide monitors (e.g., Halimeter) measure VSC levels in exhaled breath electrochemically.
- Indirect measurement techniques include the BANA test, chemical sensors (electronic nose), and beta-galactosidase activity
- The BANA test detects bacteria like Treponema denticola and Porphyromonas gingivalis.
- Chemical sensors detect specific compounds in breath
- Beta-galactosidase activity measures bacterial degradation in saliva relating to potential halitosis
Halitosis Causes
- Halitosis causes are broadly categorized as oral and extraoral
- Oral causes include bacterial biofilm, especially on the posterior dorsum of the tongue, which breaks down proteins leading to volatile sulfur compound (VSC) production. Periodontal diseases, like gingivitis/periodontitis, present anaerobic environments supporting VSC-producing bacteria.
- Extraoral causes encompass respiratory infections, gastrointestinal issues such as GERD, systemic conditions like diabetes (fruity acetone odor), and liver/kidney disease
Halitosis Management
-
Effective management of halitosis requires a multi-faceted approach
-
Oral hygiene practices, such as tongue cleaning, brushing, and flossing are important
-
Professional treatment like scaling and root planing (addressing periodontal disease) and plaque removal is crucial
-
Lifestyle modifications like avoiding odor-causing foods and staying hydrated are beneficial
-
Alternative treatments such as probiotics (reducing VSC producing bacteria), green tea polyphenols (reducing bacterial growth) alongside standard care are being explored.
