Elektrovozoremontnij teeth with neuritis lower alveolar nerve

With the defeat of the lower alveolar nerve clinic face often. The reason is purely anatomical terms that make it easily accessible for injuries block anesthesia, while pushing the filling material through the root channels in the channel of the lower jaw, surgeries, etc. To the more rare etiological factors include osteomyelitis of the mandible, infection, intoxication.
Damage signalvaluerole nerve on deletes the bottom of the tooth is so great that some foreign authors recommend each time to warn patients about possible complications. The clinical picture with neuritis lower alveolar nerve is mainly reduced to the following. Patients complain of numbness in the lower teeth, lower lip and chin on the corresponding side. Very often join complaints about some feeling of awkwardness in half lips and chin, particularly sharply manifested during the call, and affecting the clarity of pronunciation. Often along with paresthesia there are strong pain in teeth, innerved by the relevant nerve. Some of these constant pain; they subside, then increase, but not pass. In others they alternate with more or less long bright intervals. Mechanical irritation teeth provoke or exacerbate pain. The influence of temperature stimuli little, and often not expressed.
An objective study noted the loss or reduction of surface sensitivity to the corresponding half skin chin, skin and mucous membrane of the lower lip, gums lower jaw with vestibular surface (with the exception of a small area from the second premolar to the second molar, innerved buccal nerve). Percussion teeth (especially vertical) painful. In some cases there is a slight omission of the corresponding corner of the mouth that is often mistaken for the defeat of the facial nerve, meanwhile, there is a reduction of reflex appropriate tone of mimic muscles in the reduction or complete loss of sensation in the area of innervation chin nerve (like language becomes paretic - clumsy, heavy - under anesthesia in mandibular a result of loss of sensitivity in the area of innervation of the lingual nerve).
Elektrovozoremontnij teeth on the corresponding half of the lower jaw is reduced or absent. In the front teeth complete absence of excitability are very rare, since they receive innervation from the opposite side. Until relatively recently, it was assumed that from the opposite side innervation receive only cutters. Our studies of elektrovozoremontnij when mandibular the anaesthetic has shown that this applies to Fang. Sometimes not all teeth are equally affected. This is because not all the branches of the lower alveolar nerve suffer equally. Irritation shock when neuritis alveolar nerves sometimes causes the teeth feeling dull, long lasting pain (symptom indicating reaction rebirth).
