What causes molars? Treating molars requires a two pronged approach

Some people have the habit of grinding their teeth when they sleep, not only in children, but also in adults. So how to treat it?

1. Occlusal factors

Uncoordinated occlusal relationship is considered to be a major factor in bruxism, including malocclusion, missing teeth, tooth defect or length, unilateral mastication and so on. Early contact of median occlusion or lateral occlusion is the most common initiating factor of bruxism. During the tooth change period, most children can't fit the upper and lower teeth well due to the uncoordinated occlusal relationship and high contact point. Therefore, patients often have a subconscious idea. If they want to make most of the teeth in close contact, in deep sleep, this daytime idea will turn into masticatory muscle spasm and contraction, resulting in night molar.

2. Neural factors

Research shows that bruxism is a manifestation of sleep disorder, which is related to mild abnormal arousal in sleep. Studies on the central nervous system and neurochemistry show that bruxism is related to the abnormal changes of dopamine and norepinephrine, the mediators of information transmission in the central nervous system.

3. Mental and psychological factors

Mental tension is one of the causes of bruxism. Emotional tension, excessive fatigue, mental stress or children's too excited or too nervous during the day often lead to failure to fall asleep at night. That is, although most of the cerebral cortex is in an inhibitory state after falling asleep, some are still in an excited state, resulting in the contraction of masticatory muscles and molars. Patients with bruxism often have the characteristics of anxiety and psychological immaturity, and the higher the degree of anxiety, the higher the frequency of bruxism.

4. Systemic factors

Bruxism may be caused by intestinal parasitic infection, gastrointestinal dysfunction, endocrine imbalance, allergic diseases, vitamin D deficiency rickets, hyperuricemia, hyperthyroidism and bladder stress. When children have accumulated food and indigestion, the toxins secreted by bacteria in the gastrointestinal tract are absorbed and stimulated to the cerebral cortex, resulting in imbalance in the process of excitation or inhibition, resulting in nocturnal molars.

5. Genetic factors

Research shows that bruxism in childhood often persists, and genetic factors can not be ignored.

How should molars be treated?

1. Psychological and behavioral therapy

(1) Psychotherapy does have the effect of mental and psychological factors, resulting in excessive jaw muscle tension. Eliminate tension, remove unnecessary concerns and arrange work reasonably. If necessary, take diazepam orally (dependent).

(2) Reducing brain excitement, resting and relaxing before going to bed, doing appropriate gymnastics, avoiding excitable food and smoking, and improving sleep environment are conducive to reducing brain excitement. Mobilize patients' self-awareness and self-control to reduce the occurrence of teeth. It has little effect.

(3) Muscle relaxation therapy jaw muscle tension is one of the causes of bruxism. Relieving muscle tension in treatment is a necessary means to control bruxism. The commonly used methods are: the application of muscle relaxation instrument; Physical therapy, physiological function training of masticatory muscles; Massage; Audio visual suggestion and other methods. It has little effect.

2. Biofeedback therapy

(1) Arousal stimulation during sleep can wake patients up by electrical signals such as sound when molars occur through biofeedback, so as to temporarily stop molars. Some scholars conducted temporary afferent electrical stimulation on the lips, and the results were effective in controlling bruxism. However, this method interferes with the sleep of patients and cohabitants, and the effect is not long-term.

(2) Taste biofeedback some scholars sealed the disgusting but safe liquid into the capsule and put it in a comfortable position between the patient's upper and lower posterior teeth. When the patient grinds, the liquid in the capsule will squeeze out to the mouth. The strong stimulation caused by bad taste acts through the biofeedback mechanism to stop the action of grinding teeth.

3. Treatment of occlusal teeth

(1) Adjust the occlusal relationship of teeth, remove occlusal interference by grinding a small amount of tooth tissue, and establish occlusal balance relationship, so as to achieve the physiological balance among tooth jaw, masticatory muscle and temporomandibular joint, and eliminate bruxism. For patients with occlusal deformity, orthodontics or repair should be carried out first. Correct bad habits such as unilateral chewing, pencil biting and chewing gum.

(2) The use of occlusal board makes a dental pad, which is worn on the teeth before going to bed at night and removed in the morning to relieve muscle tension. At present, it is most easily accepted by doctors and patients to prevent tooth wear, but it can not treat bruxism.

4. Medication

(1) Botulinum toxin mainly focuses on trying to adjust dental and maxillofacial dyskinesia and dystonia. Local use of botulinum toxin (BTX) is effective in the treatment of dyskinesia. BTX was injected into both masseter muscles of perennial molar patients. Results most patients began to stop tooth grinding immediately to 4 weeks after injection, but some patients had difficulty swallowing.

(2) Central nervous system drugs use L-dopa to regulate the central nervous system, which can significantly reduce the number of molars, but it is easy to cause nausea, vomiting, insomnia, arrhythmia, psychotic attack and so on. It can only be considered when drug treatment for bruxism is ineffective.

(3) Other drug treatments are targeted for intestinal parasitic infection, gastrointestinal dysfunction, endocrine imbalance, allergy, vitamin D deficiency, children's food accumulation, dyspepsia and other diseases, so as to remove the possible causes of molars.

Summary: the above are the factors that cause molars in babies, especially during the period of growing teeth. If molars occur, they should pay attention to them from childhood, but some are still genetic factors, which can not be ignored. But if adults always have the habit of grinding teeth, they should also be treated in time, because this seemingly small thing actually does some harm to the body. We should find out the cause to fundamentally solve the situation of grinding teeth. Otherwise, when you sleep with your favorite partner, this small thing will affect others' feelings about you, which is not worth the loss.
