Tetracycline is a drug used to treat bacterial infections. It has a staining effect on children's teeth. In the past, the medical field did not pay attention to the staining effect of tetracycline on teeth. Now these drugs are no longer used in children and pregnant women, but some parents lack common sense in this area. When the child is sick, they blindly apply tetracycline drugs. So tetracycline teeth can still be seen in children.
Although this disease is called tetracycline tooth, it is actually not only caused by tetracycline, but also drugs like oxytetracycline, norchlortetracycline, etc. Because the structure of these drugs is similar to tetracycline. These above belong to the tetracycline drug family. Among them, tetracycline and norchlortetracycline have the strongest effect on discoloration. They damage teeth during the mineralization period of tooth development.
At this time, the tetracycline that enters the human body combines with the calcium in the teeth to form a stable substance, which affects the calcification of the hard tissue of the tooth and causes hypoplasia of tooth enamel.
When the child is not yet born or is still in infancy shortly after birth, even from 1 to 7, 8 years old, the teeth in this period are in the mineralization period, and the use of tetracycline drugs can easily cause tooth discoloration. In addition, tetracycline is very sensitive to light, so sunlight and ultraviolet rays can make it change color, and the color will gradually deepen over time.
Perhaps you would think that there might be no problem with using tetracycline once in a while? In fact, a sufficient amount of tetracycline for once can cause lifelong regrets. Tetracycline teeth doesn’t have a uniform color, which is unevenly distributed on the teeth. It mainly stains the dentin. The color changes in light yellow, dark yellow, yellowish brown, light gray, gray and black. This is related to the size and type of drug. Some severe tetracycline teeth can also develop enamel hypoplasia, leading to tooth hard tissue defects. According to statistics, nearly 1.3 percent of students have tetracycline teeth.
BALLYA provides a tetracyclines test to tell you if there are tetracyclines residues in dairy products you eat every day.
During the period of tooth development and mineralization, the tetracycline family drugs taken can be absorbed into the tooth tissue to stain the teeth.
The main effect of tetracycline on teeth is staining, and it can also cause enamel hypoplasia. The influence of tetracycline on tooth staining and enamel hypoplasia is related to the following factors:
It is mainly suitable for patients who are unwilling to remove too many teeth and require relatively low treatment costs and rapid whitening.
Standard:
Resin cosmetic repair seems to be a simple technique, but in the clinic, many failed cases have been found. The reason is that there is no deep understanding of modern various resin materials and bonding principles. In the clinical process, it is necessary to finely compare the color, strictly prevent moisture, completely remove caries, protect the pulp, layer filling, cleverly shading, enough solidification, personality shaping, careful blending, high polishing, and edge sealing. Each step needs to be meticulous, and any negligence will cause a decline in the success rate of beauty repair. As long as it is carefully repaired, satisfactory repair effects can be obtained.
The latest treatment for severe tetracycline teeth treatment is suitable for patients with tetracycline teeth who are unwilling to remove a large number of teeth.
Porcelain veneers started in the United States in the 1980s. Because natural teeth were less removed, and the color, shape, arrangement, and size of teeth can be changed to achieve perfect and lasting cosmetic effects, so it becomes the most popular cosmetic repair method in Europe and America.
Porcelain veneers are actually shell-like tiles that are glued to the surface of teeth. Commonly used materials for porcelain veneers are feldspar porcelain and the new IPS EMPREE cast ceramics. EMPRESS is a leucite-enhanced type with low casting shrinkage and high restoration accuracy. The porcelain veneer is translucent, similar to tooth enamel. Porcelain veneers use the enamel layer of teeth and rely on high-strength resin bonding to provide sufficient retention.
Advantages
A. Safety
There is less tooth tissue produced by grinding, which can save a large amount of tooth tissue without killing nerves, basically controlling the sequelae of complete crown restoration such as pulp inflammation and necrosis after surgery, and can maintain the long-term health of natural teeth.
B. Aesthetic
Good transparency and shading, with the same optical characteristics as natural tooth tissue, without any metal components, showing the best aesthetic effect, and there will never be black lines common in porcelain teeth. There are five different colors of porcelain blocks to choose from when making the cast porcelain veneer. At the same time, external dyeing can be used to fine-tune the color. There are five different shades of adhesives and white opaque agents for clinical bonding that can be used to assist in adjusting the color of the porcelain veneer to achieve an overall coordinated beauty effect. And the high wear resistance and non-coloring of the porcelain itself can achieve permanent whitening effect.
C. Health
Porcelain veneer has excellent light transmittance, and the gums can be flattened during tooth preparation, which is conducive to impression and bonding. The area that connects with the gums is also only on the labial side, which irritates the gums less. There will be no discoloration of the gums caused by the metal ions of the metal porcelain teeth. The hardness of the porcelain crown is greater than that of the tooth enamel, which can cause wear on the jaw teeth. The hardness of IPS Empress cast porcelain is lower than enamel, which can effectively protect the opposite jaw.
D. Comfortable
Full crown restoration needs to grind off the natural teeth on the lingual side, and the teeth on the lingual side are usually healthy, and are in the most coordinated state with the tongue and antagonist teeth. The best porcelain crown cannot be restored to the previous status. Porcelain veneer restoration preserves most or even all of the lingual shape, effectively protecting the opposite jaw.
Disadvantages
It is mainly suitable for severe tetracycline teeth with dental hypoplasia or fragile dentin, re-tetracycline teeth, etc.
Tetracyclic bisque porcelain crown restoration can obtain the best aesthetic effect, but aesthetics is not the most critical issue for tetracyclic bisque porcelain crown restoration. Even the most mediocre dentist can make a porcelain crown with a completely different color from the original.
The most important thing is to obtain the best aesthetic effect while maintaining the long-term health of the teeth, because the age of patients with severe tetracycline teeth is between 30 and 40 years old, and the average life age is 80, which means that these teeth have to last for at least 40 years.
Porcelain crown restoration requires a certain amount of teeth to be abraded, so there is a certain amount of damage to the teeth. How to obtain the best aesthetic effect with the minimum physiological cost and good long-term effect? It requires doctors to have a high degree of responsibility, love, proficient operating skills and a solid theoretical foundation.
Tetracycline teeth are often caused by the absorption of tetracycline through the placenta or feeding during the child's tooth development. Tetracycline teeth can damage children's self-esteem and self-confidence. Although there are many options for later treatment, it is complicated and time-consuming. So the best way is to prevent it early.
