Teeth are small and dull
Introduction
Introduction The shape of the tooth is small, and its dullness is mostly due to the administration of a tetracycline-based drug during the developmental mineralization period of the tooth, and can be incorporated into the dental tissue to form a tooth. Causes dullness of the teeth. During the mineral development mineralization period, the tetracycline-based drugs taken can be incorporated into the dental tissue to color the teeth. The main effect of tetracycline on teeth is coloration, which can also be combined with enamel hypoplasia. In the early stage of chronic fluorosis, the enamel loses its color and becomes dark or spotted. In the late stage, there are chronic cough, back and lower limb pain, osteosclerosis, tendon, ligament calcification and joint capsule hypertrophy, bone hyperplasia, joint deformation and so on.
Cause
Cause
During the mineral development mineralization period, the tetracycline-based drugs taken can be incorporated into the dental tissue to color the teeth. The main effect of tetracycline on teeth is coloration, which can also be combined with enamel hypoplasia. The effect of tetracycline on tooth coloration and enamel hypoplasia is related to the following factors:
1. The color of the tetracycline drug itself, such as: demethylated chlortetracycline is cadmium yellow, oxytetracycline is lemon yellow.
2. The color of tetracycline is degraded because tetracycline is sensitive to light and can change color under ultraviolet light or sunlight.
3. Tetracycline In the dentin, the degree of dentin coloration is different due to the depth of the binding site. When the coloring band is closer to the enamel dentin, the coloring is easier, so when the outer layer of dentin is formed in the early stage of the baby, The drug has the greatest impact.
4. It is related to the structure of enamel itself. When severe enamel is underdeveloped and enamel is completely lost, the dentin is obviously exposed. If the enamel is not fully developed, the enamel loses transparency and is white and succulent. Covering the pigmented dentin, the teeth are close to normal.

Small and dull examination of teeth:
In the early stage of chronic fluorosis, the enamel loses its color and becomes dark or spotted. In the late stage, there are chronic cough, back and lower limb pain, osteosclerosis, tendon, ligament calcification and joint capsule hypertrophy, bone hyperplasia, joint deformation and so on.
The diagnosis of typical skeletal fluorosis is not difficult:
1. People who have been living in and drinking high fluoride water for more than two years in endemic areas of skeletal fluorosis, or those with dental fluorosis.
2. The clinical manifestations are consistent with the symptoms and signs of typical skeletal fluorosis.
3. Radiological examination revealed a change in bone specificity.
4. Those with a diagnostic laboratory test positive.
5. Bone biopsy is consistent with skeletal fluorosis.
Diagnosis
Differential diagnosis
Symptoms of small, dull teeth and confusion:
Abnormal teeth: The development of human teeth is a complex and lengthy process. In this long process, various unfavorable factors inside and outside the body can cause different types of developmental abnormalities in different stages of tooth development, such as abnormal teeth eruption, abnormal number, abnormal morphology and abnormal tooth structure. 1. Look at the number, shape, color and arrangement of the teeth for abnormalities. Whether there is white color, light yellow, yellow brown. Ink immersion, dark brown. Whether the damaged part is at the tip of the crown or the neck is linear, dotted or full crown discolored. 2. Probing to explore the defect area of the tooth with a sharp probe to understand the hardness of the tooth. The dentin is soft and the caves are mostly rickets, such as hard dentin, rough tooth surface, and uneven enamel dysplasia.
Large gaps in the teeth: It is because of the poor development of the teeth or the large gap between the teeth caused by the damage of the posterior teeth, which leads to eating teeth or affecting the appearance of the teeth.
The teeth are small and translucent: the dentate hypoplasia syndrome affects the deciduous teeth and the permanent teeth, which can occur when the teeth are long after birth. The teeth are small, translucent, with a brownish-yellow or orange-yellow color. This condition affects both the deciduous and permanent teeth, which can occur when the teeth are born after birth. The teeth are small, translucent, with a brownish-yellow or orange-yellow color. The texture is fragile and easy to break, but there is no looseness. All or most of the teeth can be gradually worn out.
Abnormal color of teeth: Because the surface of the tooth is covered with a layer of enamel, it is transparent or translucent, and its deep part is dentin, which is pale yellow. The color of the teeth is related to the degree of calcification of the enamel. The higher the degree of calcification, the more transparent the enamel is, and the true color of the deep dentin through it makes the teeth pale yellow, and the color of the teeth is abnormal in various dental diseases.
In the early stage of chronic fluorosis, the enamel loses its color and becomes dark or spotted. In the late stage, there are chronic cough, back and lower limb pain, osteosclerosis, tendon, ligament calcification and joint capsule hypertrophy, bone hyperplasia, joint deformation and so on.
