What Is Tetracycline Staining?
Tetracycline is an antibiotic synthesized by tetracycline-catalyzed dehalogenation. It has low toxicity. Tetracycline is deposited on teeth, bones, and even nails, which causes hypoplasia of dental enamel. In this regard, it has attracted attention in China until the mid-1970s.

Basic Information
Causes of Tetracycline Teeth
- Tetracycline drugs taken during the mineralization of teeth can be incorporated into tooth tissue to stain the teeth.
- Tetracycline's main effect on teeth is coloration, which can also be combined with enamel hypoplasia. The influence of tetracycline on tooth staining and enamel hypoplasia is related to the following factors:
- 1. The color of the tetracycline family drugs, such as: demethyl amycin is cadmium yellow, oxytetracycline is lemon yellow.
- 2. The color of tetracycline, because tetracycline is sensitive to light and can change color under ultraviolet or sunlight.
- 3. Tetracycline in dentin has different degrees of dentin coloring due to the depth of the binding site. The closer the coloring band is to the enamel dentin boundary, the easier it is to color. Therefore, when the outer dentin is formed in the early stages of the baby, Medication has the greatest effect.
- 4. It is related to the structure of the enamel itself. When the enamel is severely underdeveloped and the enamel is completely lost, the colored dentin is obviously exposed; if the enamel is mildly underdeveloped and the enamel loses transparency and appears chalky, Covering the stained dentin, it makes the tooth color close to normal.
Tetracycline teeth clinical manifestations
- 1. It is yellow, showing bright yellow fluorescence under sunlight, and then gradually changes from yellow to tan or dark gray. This transition is slow and can be promoted by sunlight, with the discoloration of the lip surface of the incisors first.
- 2. The anterior teeth are more stained than the posterior teeth; the deciduous teeth are more stained than the permanent teeth, because the enamel of the deciduous teeth is thinner and more transparent, and it is difficult to cover the color of the tetracycline conjugate in the dentin.
- 3. The degree of tooth staining is related to the type, dose and number of administration of tetracycline. It is generally believed that tetracycline, nortetracycline, and tetracycline hydrochloride cause more staining than oxytetracycline and chlortetracycline. In permanent teeth, the number of cycles of tetracycline is proportional to the degree of coloration, but a large dose in a short period of time has a greater effect than an equivalent total dose in the long term.
- 4. Tetracycline causes tooth staining and enamel hypoplasia, which can only be manifested by administration during tooth development. Usually after 6 to 7 years of age, it will not cause noticeable tooth discoloration.
Tetracycline teeth diagnosis
- Combined with medical history, oral inspection can be diagnosed.
Tetracycline teeth differential diagnosis
- Differentiated from hereditary opalescent dentin. The crowns of hereditary opalescent teeth are translucent opalescent, which can be light yellow or brownish yellow. The enamel is easily broken, especially the incisor incisors and the conjunctiva of the molars are prone to enamel loss and dentin exposure. After dentin is exposed, it is easily abraded, and it appears as the appearance of dentin plane after severe abrasion.
Tetracycline Teeth Treatment
- Visible light composite resin restoration method: remove lip enamel 0.1mm or not, because tetracycline is mainly stained in dentin, if too much enamel is removed, or dentin is exposed, it will not only increase the ground color, but also seriously affect the strong adhesion Sex.
