DISEASES OF THE TEETH AND ALVEOLAR PROCESS : HYPERSENSITIVITY OF DENTIN (HYPERAESTHESIA DENTINI) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
Etiology. Most often, the exposure of dentin due to exposure of the neck of the tooth as a result of atrophy of the gums. In some cases, increased sensitivity arises due to the soshlifovyvaniye enamel for the preparation of a tooth to fixing the crown.
The pathogenesis. The outer layer of tooth enamel, protecting the delicate tissues of the tooth, plays the role of a barrier, isolating the dentin and the pulp from the coarse outer stimulations. With the loss of this external skin develops hyperesthesia.
Symptoms. Pain on contact with cold, sour, sweet, from mechanical stimuli - touch neutral food, toothbrush, dental Bora. The pain quickly terminated after removal of the stimulus.
Course and complications. A characteristic feature of hyperesthesia is a gradual increase in pain response to external stimuli. Complications depend on the underlying causes of hyperesthesia. The most dangerous are hypersensitivity resulting from soshlifovyvaniye enamel with dentures.
The presence of a naked dentin, anatomic failure of the enamel. Functional deficiency of enamel. The pain from the cold, sour, touch, quickly disappearing after the cessation of the irritation is a common symptom.
Immediate replacement of lost enamel cover using those or other artificial measures (crowns, fillings) in cases of artificial soshlifovyvaniye.
Local flyuorizatsiya with fluoride toothpaste (natalizie 75% Lukomsky). Rubbing a paste of chloride of strontium, sulfidina, soda. Lighting ultraviolet rays.
