Bad breath

Introduction Bad breath is a symptom of odor in the mouth. Bulimia spicy food or overeating, fatigue, excessive heat, stagnation, or certain oral diseases, such as oral ulcers, dental caries and digestive diseases can cause bad breath. Chinese medicine believes that bad breath is caused by lung, spleen, stomach heat accumulation or food accumulation. These things become a toxin when they are not deposited in the body for a long time. The formation of bad breath is mostly formed by the long-term accumulation of body toxins. Therefore, the elimination of bad breath needs to be fundamentally adjusted to the body before it can be eradicated. It must not be rushed to use some drugs that are more irritating to the gastrointestinal tract. The prescription is adjusted to fundamentally relieve bad breath.

Cause

(1) Dietary breath

Eating certain foods, such as garlic, onions, leeks, stinky tofu, etc., have specific odors. When stored in the mouth, they can emit corresponding odors, heat, vomiting, hiccups, and often the contents of the gastrointestinal tract. The smell is transmitted out of the body.

(2) Foreign body corruption

The food residue remaining in the tooth gap is rotted by bacteria to produce an odor.

(three) tissue necrosis

Human tissue is mainly composed of protein, which produces odor such as hydrogen sulfide after decomposition.

(4) Bacterial twins

Some bacteria in the mouth and respiratory tract decompose proteins and starch, and a large number of bacterial metabolites such as strontium, sulfhydryl and ammonia can cause bad breath.

(5) Substances contained in blood

In diabetic ketosis and uremia acidosis, the blood ketone and urea components increase, and the blood flows through the alveoli to distribute the ketone and the decomposed urea to the body, so that the patient may have an acetone smell or a rotten apple smell.

1. Feedback method for close people: According to the feedback from relatives, friends or spouses.

2. Sensory perception analysis method: The analysis method selects the following six parameters.

1 full mouth breathing smell;

2 speech smell, also known as 20 count test;

3 tongue anterior area smell, also known as wrist test; 4 tongue behind the area smell, also known as plastic spoon test;

4. Chemical analysis method:

1 Gas chromatography/mass spectrometry is a gas chromatograph for detecting exhaled gases from a subject.

3 High-pressure liquid chromatography (HPLC) was used to detect rancid compounds such as cadaverine in saliva.

4 The zinc oxide thin film semiconductor sensor uses a mouth exhalation into a bag for detection.
