What reason is the child often molar?
summary
Molars in sleep are more common in children, adults can also occur. The contraction of masticatory muscle is controlled by trigeminal nerve. When trigeminal nerve is excited, it will lead to repeated contraction of masticatory muscle. The upper and lower teeth collide with each other and make a sound, which leads to molar phenomenon. When molting teeth at night, the teeth form "dry grinding",. Ah, wear is very serious, leading to varying degrees of sensitivity. This kind of excessive chewing can also lead to the destruction of the tissue around the teeth, make the teeth loose and shift, and even cause gingival atrophy or alveolar bone loss. The main causes of molars at night are as follows
What reason is the child often molar?
Biliary parasites are mainly caused by biliary Ascaris. Ascaris lumbricoides can secrete a variety of toxins. In addition, the metabolites of Ascaris lumbricoides can stimulate the corresponding parts of the brain in deep sleep, causing some people to have continuous contraction of masticatory muscles and molars.
Occlusal dysfunction is the most important cause of nocturnal molars. Occlusal dysfunction destroys the coordination of masticatory organs, so the body increases tooth grinding to remove occlusal dysfunction. Dental caries is not treated in time, and then pulpitis, periapical periodontitis, pain, abscess, and even premature loss of deciduous teeth will occur, which will lead to unilateral mastication habit, long-term unilateral mastication, uneven occlusion and occlusal disorder, resulting in persistent nocturnal molars; Uneven dentition, such as crowding, reverse occlusion, open occlusion, etc., will make the occlusion uncoordinated, resulting in molars at night.
Psychological factors include mental stress, fright, emotional excitement and fatigue. After sleeping, although the cerebral cortex is in a state of inhibition, there are still some areas (such as the trigeminal nerve) in an excited state, leading to molars.
matters needing attention
To treat molars at night, we should first find out the causes, symptomatic treatment can be cured. Children's tooth change period, may appear because of gingival itching molar symptoms, this phenomenon is normal, after the tooth change period will basically disappear.
