Study Notes
Oral Bacteria and Halitosis
- Over 500 bacterial species reside in the oral cavity
- Many of these species can produce odorous compounds, causing halitosis (bad breath)
- Poor oral hygiene contributes to the multiplication of halitosis-causing bacteria
- The most common bacteria associated with halitosis are Gram-negative species and proteolytic obligate anaerobes
- These bacteria mainly reside in the tongue coating and periodontal pockets
Volatile Compounds and Halitosis
- Volatile sulfur-containing compounds, along with short/medium-chain fatty acids, alcohols, and volatile aliphatic compounds, contribute to halitosis
- Some healthy individuals may experience occasional halitosis due to bacterial retention on the tongue surface
Periodontal Health and Halitosis
- Poor periodontal health leading to periodontal pockets can increase bacterial retention and, therefore, halitosis
- The relationship between periodontal health and oral malodors is not fully understood
Other Factors Contributing to Halitosis
- Untreated deep carious lesions can trap food debris and bacterial plaque
- Reduced salivary flow, caused by factors like medications, salivary gland diseases, or xerostomia, exacerbates halitosis
- Saliva plays a role in buffering and self-cleaning of the oral cavity
- Reduced salivary flow hinders these processes, leading to bacterial build-up and halitosis
Pathological Factors in Halitosis
- Exposed tooth pulps, non-vital teeth with fistulas draining into the mouth, oral cancers, and ulcerations can contribute to halitosis
- Oral cavity pathologies, extractions/healing wounds, prosthetics, orthodontic appliances, and poorly-fitting restorative crowns can all lead to bacterial retention
Diagnostic Testing for Halitosis
- The BANA test checks for the presence of Tannerella denticola, Porphyromonas gingivalis, and Bacteroides forsythus, which are common contributors to halitosis
- The BANA test results have shown a positive correlation with increasing pocket depth
- Salivary incubation tests involve incubating saliva in anaerobic conditions to evaluate the odor produced by bacteria
- This method is less influenced by external factors like smoking, drinking coffee, and spicy food
Advantages of the Salivary Incubation Test
- Salivary incubation tests are less influenced by external factors compared to organoleptic measurements
- The test allows for controlled evaluation of halitosis without interference from other factors
Management of Halitosis
- Understanding the contributing factors is essential in managing halitosis
- Treatment strategies include improved oral hygiene, professional dental care, and addressing underlying medical conditions
- Lifestyle modifications like quitting smoking and managing dietary habits can also be helpful
