Teeth are small and translucent
Introduction
Introduction Pediatric dentine hypoplasia syndrome involves the deciduous and permanent teeth, which can occur in the long teeth after birth. The teeth are small, translucent, with a brownish-yellow or orange-yellow color. The enamel is easily lost, especially the joint of the incisor and the molar is prone to enamel loss, and the dentin is exposed, but there is no looseness. The main reason is the imbalance of systemic nutrition, especially the imbalance of calcium, phosphorus, vitamin A, vitamin D and vitamin C. 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.
Cause
Cause
Causes of small, translucent teeth
(A) the cause of the disease: the disease is an autosomal dominant hereditary disease.
1. Systemic malnutrition: especially disorders of calcium, phosphorus, vitamin A, vitamin D, and vitamin C.
2. Systemic or local infections: high fever or metabolic disease, pediatric measles, scarlet fever, deciduous apical inflammation.
3. Genetic factors.
(two) pathogenesis
The disease is caused by enamel and essential dysplasia, and the disease is formed after birth. Pathological examination showed that the roots were slender, the medullary cavity was small, the dentin hardness was significantly reduced, and the structure was destroyed, but the pupil was rare.

Small, translucent examination of the teeth
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.
1. Mild: The enamel is normal in shape and has no substantial defects. The enamel is white and opaque, the surface is loose and rough, and sometimes it is yellowish brown.
2. Severe: enamel substantial defects There are banded or nest-like depressions on the surface of the teeth. The coloration is white or yellowish brown. In severe cases, there is no enamel formation or crown shape change or shrinkage.
3. Caused by systemic factors: enamel hypoplasia caused by systemic factors, the left and right teeth of the same name are symmetrical, and the development of the teeth at the same time is involved.
Diagnosis can usually be made according to clinical manifestations, and the removal of the diseased teeth can be confirmed by pathological examination.
Diagnosis
Differential diagnosis
Smaller, translucent, confusing symptoms
Abnormal dental morphology: the shape and size of the teeth, like the physical appearance, affected by genetic factors, the mode of action, is still unclear. A few under the influence of environmental factors, such as mechanical pressure, can also cause variations in tooth morphology Common tooth morphology abnormalities are as follows: malformed cusps, deformed sockets, deformed teeth, deformed teeth, curved teeth, etc.
The teeth are small and dull: the shape of the teeth is small, and the dullness is mostly due to the administration of tetracycline drugs during the mineralization period of the teeth, which can be incorporated into the dental tissues to form teeth. Mostly due to the use of tetracycline drugs in the developmental mineralization period of the teeth.
The teeth are small and sparse: the shape of the tooth is small, the shape of the jaw is normal, etc., and the gap between the teeth is formed to form a sparse tooth. Small and sparse teeth can easily jam food and damage periodontal tissues, causing gingivitis, periodontitis, and easy to change. Severe cases can affect the appearance of the patient and cause mental and mental disorders. The disease is treated differently according to the cause of sparse dentition.
