Introduction

Introduction Bruxism refers to a brux that has a habitual molar when sleeping or an unconsciously used tooth when it is awake. The disease is common in the clinic, and the treatment effect is not obvious, and often brings a mental burden to the patient. After a long time, the patient may suffer from chewing weakness and temporomandibular joint fatigue. Serious nighttime bruising can also affect the rest of others, and even have adverse consequences.

Cause

Cause

There are four main reasons:

(1) psychological factors such as nervousness, psychological anxiety, depression, and anger.

(2) Gastrointestinal diseases, endocrine disorders can also cause this disease.

(3) Excessive fatigue, engaged in fine workers, such as athletes, watchmakers, etc.

(4) The lack of trace elements in the body is prone to this disease.

In addition to the above-mentioned people, people who are introverted, emotional, and often bitten into the mouth are also prone to bruxism.

Common causes of children:

1. Intestinal parasitic diseases, especially intestinal ascariasis, are quite common in children.

2, gastrointestinal diseases, oral diseases.

3, before going to sleep to the children to eat non-digestible food, so that after the baby sleeps may stimulate the corresponding parts of the brain, through the nerves cause the masticatory muscles continue to shrink.

4, nervous system diseases, such as psychomotor epilepsy, rickets and so on.

5. Children's mental factors such as emotional excitement, excessive fatigue or emotional stress during the day.

6, lack of vitamins, children with vitamin D deficiency rickets, due to calcium and phosphorus metabolism disorders, can cause bone decalcification, muscle soreness and autonomic disorders, often sweating, night terrors, irritability and night molars .

7, the teeth are not aligned, the masticatory muscles are too strong or long-term chewing with one side of the teeth, and the tooth occlusion is not good, temporomandibular joint dysfunction, can also cause night molars. Moreover, children with irregular teeth are often in an abnormal position in their masticatory muscles. At night, the masticatory muscles often contract unconsciously, causing molars.

8. In addition, during the period of changing teeth between 8 and 11 years old, it is easy to produce slight molars due to itching of the gums. During this period, mild molars are normal, and if it is serious, it needs treatment. After this stage, usually Will disappear on its own.

It can be seen that the molars are basically caused by certain diseases. Some children have a long time for grinding. Although they have been treated accordingly, the cerebral cortex has formed a strong conditional reflection, so the molar movement at night will not disappear immediately. In particular, although the gastrointestinal disease has improved, but the gastrointestinal dysfunction still exists, so the molar movement can not be corrected in a short time, must adhere to a longer period of treatment to get better.
