Symptoms of enamel corrosion confusing
1, tetracycline teeth
a. It is yellow, showing a bright yellow fluorescence under sunlight, and then gradually changes from yellow to brown or dark gray. This transformation is slow and can be promoted by the sun, so the lip of the incisor is first discolored.
b. The anterior teeth are more colored than the posterior teeth; the deciduous teeth are more colored than the permanent teeth, because the enamel of the deciduous teeth is thinner and more transparent, and it is not easy to cover the color of the tetracycline conjugate in the dentin.
c. The degree of tooth coloration is related to the type, dose and number of doses of tetracycline. It is generally believed that the coloration caused by tetracycline, normycin, tetracycline hydrochloride is more pronounced than oxytetracycline and chlortetracycline. In permanent teeth, the number of treatments for tetracycline is directly proportional to the degree of coloration, but a short-term high-dose dose is more effective than a long-term uniform dose.
d. Tetracycline causes tooth coloration and enamel hypoplasia, which can only be manifested when administered during tooth development. In general, administration after 6 to 7 years of age does not cause distracting tooth discoloration.
2. Caries: It is a disease in which the tooth undergoes progressive destruction of the tooth enamel, dentin or cementum under the influence of external factors.
3, opalescent teeth: opalescent teeth are autosomal dominant inheritance, can appear in a family for several generations, but there may be intergenerational genetic phenomena. If one of the parents is a sick person, the number of sick children is about half, and the male and female morbidity rates are equal. Both milk and permanent teeth can be affected. The opalescent teeth can coexist with bone insufficiency (bone fragile, blue sclera, otosclerotic deafness), albinism and cardiac malformation.
4, pigmentation: generally deposited on the surface of the crown of plaque, tartar, soft scale and pigment (smoke, tea) stains, etc., often the tongue of the teeth is heavier than the cheeks, the lower jaw is heavier than the upper jaw. Careful observation shows that it adheres to the tooth surface, and external force can be removed.
