Oral local disease is the main cause of halitosis, but what should not be
ignored is that halitosis is also often oral manifestation of some serious
systemic diseases. There are some organic disorders that can also cause
halitosis.
Here we would like to offer you some halitosis professional diagnosis.
1. Clinical testing method: mainly includes the add shanghai dental experiment and
plastic spoon experiment;
2. Professional doctor’s direct nose measurement method: is an objective
evaluation method of halitosis that is easy to perform, and is one of the most
accurate methods. The diagnosis is made by professional physicians of nasal
test, using the standard of 0 ~ 5 score to measure the degree of halitosis and
the repeatability of the result is accurate.
3. The laboratory tests: chemical analysis (gas chromatography/mass
spectrometry sulfide monitor, high performance liquid chromatography analysis,
zinc oxide thin film semiconductor sensor, BANA), milk gargle oxygen depletion
experiment, the cultivation of microorganisms and fungi detection, saliva
cultication.
4. Artificial nose: including portable sulfide meter and electronic nose,
which is using the principle of chemical reaction, demonstrating the PPB
concentrations of H2S in the mouth in the form of digital. The method is simple,
easy to operate, but vulnerable to the effects of oral other scents, such as
alcohol, volatile flavor (perfume, hairspray, etc.). Electronic nose is a way to
diagnose the bad breath by identifying the characteristic odor in the mouth of
patients, but at the moment, its function is yet to be improved. Shanghai dental
can diagnose out your halitosis scientifically.
According to statistics, 80% ~ 90% of the halitosis comes from the mouth. In
the mouth, the untreated dental caries, residual roots and residual crowns, bad
repair body, abnormal anatomy, gingivitis and periodontitis, and oral mucosal
disease can cause bad breath. The dental caries and periodontal disease is the
most common related disease. In the deep hole of caries socket and under the bad
repair body suspension, there is often remaining food residue and plaque, and
bacteria can break down after fermentation, producing odor. Untreated pulp
necrosis or purulent pulpitis, also can produce stinking odor. Periodontal
disease patients are often accompanied by a large number of plaque and the
bacteria inside the periodontal pocket can produce hydrogen sulfide, indoles and
ammonia class after fermentation, thus producing bad smell. In addition,
overflow pus of periodontal abscess and periodontal pocket is more likely to
have been infected by staphylococcus aureus merger periodontal pathogens, which
also can stink. The quantity and quality of the saliva also play an important
role. The reducing of saliva quantity and the increasing of organic ingredients
such as protein reduce the flushing action and cushion of saliva and make the
bacteria multiply. The decomposition of saliva and gingival sulcus fluid and
food residue of organic composition produce a large number of substances such as
volatile sulfide, indole, causing bad breath.
Oral adjacent tissue diseases such as suppurative tonsillitis, chronic
maxillary sinusitis, and atrophic rhinitis and so on, can produce purulent
secretion and stink. Clinically common medical diseases such as acute or chronic
gastritis, peptic ulcer will also make stink. Pyloric obstructions, advanced
gastric cancer often appear duck eggs fetor smell. Other diseases such as
leukemia, lack of vitamin, heavy metal poisoning can also cause bad breath.
