Molar

Introduction to molars Bruxism refers to a person who has habitual molars or white sputum during sleep and has a habit of grinding teeth. It is a long-term vicious circle disease. Night molars are trigeminal dysfunction caused by abnormal excitation of part of brain cells in the cerebral cortex of the central nervous system. The trigeminal nerves exert a strong persistent non-functional contraction of the masticatory muscles, causing the chewing movement of the teeth. Generally divided into 3 types: molar type, tight bite type and mixed type. People between the ages of 6 and 13 are in the period of changing teeth, and there will be molars in order to adapt to the upper and lower teeth. However, if adolescents and adults who have passed the tooth-changing period often have molars, it is a pathological condition. basic knowledge The proportion of illness: 0.03%--0.05% Susceptible people: children Mode of infection: non-infectious Complications: wear, headache, constipation, bad breath

Cause of molars

The effects of children's emotions and lifestyle:

Nowadays, children usually learn to be nervous and stressful. At the same time, there are many children watching the thrilling fighting TV in the evening, and playing too much before going to sleep. These factors will cause the molars. In addition, if you have been scolded by your father and mother for a long time, Repression, uneasiness and anxiety can also occur at night.

The teeth are not aligned:

Excessive use of masticatory muscles or long-term chewing with one side of the teeth, and poor occlusion of the teeth, dysfunction of the temporomandibular joint, can also cause nighttime molars, and the teeth are not arranged neatly, the position of his masticatory muscles is often Not normal, when sleeping at night, the masticatory muscles often contract unconsciously, causing molars.

Intestinal parasitic diseases:

In particular, intestinal tsutsugamushi is quite common among children.

Gastrointestinal diseases, oral diseases:

Before going to sleep, give the children a food that is not easy to digest, so that after the baby sleeps, it may stimulate the corresponding parts of the brain, and the masticatory muscles continue to contract through the nerves.

Nervous system disease:

Such as psychomotor epilepsy, rickets and so on. Children have emotional factors such as emotional excitement, excessive fatigue or emotional stress during the day.

Lack of vitamins:

Children with vitamin D deficiency rickets, due to calcium and phosphorus metabolism in the body, can cause bone decalcification, muscle soreness and autonomic disorders, often sweating, night terrors, irritability and nighttime molars.

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. If it is serious, it needs treatment. After this stage, it usually disappears 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. It is easy to form a habitual molar, especially if the gastrointestinal disease is improved, but the gastrointestinal dysfunction still exists, so the molar movement can not be corrected in a short time, and it must be maintained for a long time to improve.

Molar prevention

1. Try to relax yourself before going to bed, especially before going to sleep, you can do some gymnastics, bubble hot bath, and listen to light music.

2. Avoid excitatory foods and smoking, and improve the sleeping environment.

3, try to avoid containing caffeine and other beverages or food, such as coffee, chocolate, cola, etc. try to avoid.

4, eat more foods rich in vitamins.

5, to know how to relieve stress, relax, adjust mentality.

6, hot compress the upper and lower jaws, can loosen the muscles of the jaws, but also reduce the chance of headache.

7, keep the correct posture, bending over the hunchback will lead to the molars.

8, must brush your teeth before going to bed, do not have enough dinner.

9, daily diet pay attention to calcium, regular deworming.

10. Keep your mouth in a healthy rest during the day, that is, keep your teeth relaxed.

Molar complications Complications, abrasion, headache, constipation, bad breath

Because the night molars cause strong slamming of the teeth together, and no food is alleviated, the protective material on the surface of the teeth is excessively worn, and the dentin under the protective substance is exposed, and the food is allergic to cold, heat, acid, sweetness and the like. In severe cases, the gums may often bleed, become inflamed, loosen or even fall off.

The most serious hazards are the clenching teeth and the night molars at night. The children's night molars are more common. Although the night molars will not feel any pain for a while, but in the long run, it can cause serious wear and tear of the occlusal surface and adjacent faces, and concurrent In the above-mentioned various conditions, refractory bruxism can lead to destruction of periodontal tissues, loose or displaced teeth, gingival recession, loss of alveolar bone, and we also rub the teeth during the day to rub the teeth, but there is little damage to the teeth. When chewing, the food between the upper and lower teeth is like a mat, and there is enough saliva to make the teeth smooth, so it is not easy to wear. It seems to chew for a long time when eating, but most of the time is moving up and down, really Direct tooth contact has been studied for only about 4 minutes. If you grind your teeth at night, the situation is very different. There is no food in the mouth, the secretion in the mouth is reduced, the teeth are not lubricated, and the "dry grinding" is formed. It is like pushing a grinder, so the wear of the teeth is very big, and the consequences are quite serious. At this time, the worn teeth tend to have no The acidity or pain of the same procedure sometimes causes temporomandibular joint dysfunction, which destroys the shape and function of the occlusal system, which can cause abnormal function of the masticatory muscles, such as hyperfunction of the masticatory muscles, paralysis, fatigue, pain, etc. Muscle contraction imbalance, abnormal occlusal position, vertical height change between the jaws, imbalance of position of the discoid, directly affecting the normal shape and function of the temporomandibular joint, showing pain at the mandibular joint, joint bounce, restricted mouth opening, etc. Symptoms, pain is oppressive and blunt, especially in the morning to get up, night molars can affect others' sleep.

In addition, long-term night molars may also cause a series of complications, such as: causing the masticatory muscles to get no rest, causing fatigue and pain in the masticatory muscles, and helping the pain. In severe cases, headaches, neck and back pains. It can also lead to decreased sleep quality, memory loss, bad breath or bad breath, damage to hearing and taste. Individuals with heavy molars can cause facial asymmetry. It usually manifests as a large face and a small face, which leads to psychological depression and pessimism. There are even terrible consequences such as suicide, and many severe patients are accompanied by gastrointestinal disorders, constipation, decreased sleep quality, fatigue, lack of energy, and lack of interest in things, especially because the quality of sleep is affected by molars. It is easier to be tired, so we must pay attention to it.

Long-term molars will cause extensive loss of tooth tissue, tooth shape damage, sharp edges, often stab the lips and cheeks, soft tissue of the tongue, face 1/3 of the face is old, affecting the patient's facial beauty and pronunciation, the gums often bleeding, inflammation, Causes loosening and falling off of the teeth, tooth wear causes allergies, cold and sour pain, pain in the gang and side ears, damage to the neck and neck muscles, soreness and stiffness, leading to recurrent headaches, causing biting and smashing, biting the gums, Scratching the teeth, biting off the tongue, affecting the development and psychological health of the adolescent body. The snoring of the teeth affects the rest of the family. In addition, if the child grinds his teeth, it will affect his growth and development, and there will be picky eaters, resulting in uneven nutrition and body. Short, thin, and the teeth of the child are developing, the teeth will also damage the beauty of the child's teeth, so parents must pay special attention.

Symptoms of molars Common symptoms Night molars, children love to bite nails, unconsciously bite the teeth during the day

People between the ages of 6 and 13 are in the period of changing teeth. In order to adapt to the upper and lower teeth, there will be molars. However, if the adolescents and adults who have passed the tooth replacement period often have molars, it is a pathological condition.

1 molar type: often rubbed after falling asleep at night, is the night molars that people often say, when the patient is doing molars or clenching teeth during sleep, because the teeth are often accompanied by a "squeaky" sound, usually called "biting teeth", Because it occurs mostly during sleep at night, it is also called "night molars". The patient himself is not aware of it. He is often told by others that he is more concerned about affecting others, especially his spouse.

2 bite type: often unconsciously bite the teeth when the concentration is concentrated during the day, but there is no phenomenon of upper and lower teeth.

3 mixed type: both the night molars and the phenomenon of clenching teeth during the day.

Molar examination

Clinical characteristics check: During sleep, the patient makes molar teeth or clenches the teeth. Because the teeth are often accompanied by a squeaky sound, it is usually called biting. No abnormalities in the oral mucosa.

Laboratory examination: Because the cause of the disease is related to the infection of the parasite and calcium deficiency, the main clinical examination of parasites and serum calcium levels can often be found in the stool.

Molar diagnosis

diagnosis

1. The patient has typical molars or clenched teeth during sleep.

2. Visible stubborn bruxes, the joint surface, the adjacent surface is severely worn.

3. There are changes in periodontal, alveolar bone, gingival atrophy, loose teeth, displacement and the like.

4. The muscles of the chewing muscles are weak and the bite is weak.

5. With symptoms of temporomandibular joint dysfunction.

6. After getting up, the patient has symptoms of head and neck pain.

7. More common in children, adolescent male patients.

8. I feel a pain in my ankle when I have breakfast.

Differential diagnosis

The disease is a functional disorder, and no complications occur, so the clinical identification is mainly differentiated from oral infectious diseases. For the infection with oral plaque, the damage of the teeth may occur, and the teeth may be worn at night due to itching of the teeth. Action, obvious dental caries and plaque can be found in the clinical physical examination of such cases, so it can be identified according to clinical characteristics and physical examination.
