The clinical manifestations of hereditary papillary dentition are translucent papillary, which can be light yellow or brownish yellow. The translucent milky color of the crown is usually, hereditary dentin hypoplasia. It is a common oral disease with a high incidence in children. The main presenting symptoms are abnormal calcification and defects in dentin, normal enamel development, but easy separation and loss from the dentin surface, leaving the dentin exposed and causing crown wear. The disease is autosomal dominant and can affect both milk and permanent teeth. What are the preventive and therapeutic measures for translucent opalescent crowns? It is a genetic disease and there are no effective preventive measures. The principle of treatment is to prevent pathological wear of the teeth and to protect the crowns. The anterior teeth can be restored with hooded crowns or light-cured composite resin, and the posterior teeth can be restored with metal crowns. Because the dentin itself is not hard enough, local restorative treatment alone is not effective. The affected tooth should not be used as a bridge abutment or for orthodontic treatment because it is highly susceptible to root fracture when under pressure. Depending on the symptoms, there are different dietary requirements for different conditions. Ask your doctor to set different dietary standards for the specific disease. The disease is autosomal dominant and can involve both papillary and permanent teeth. The gene that causes the disease is located at 4q13, and some patients also have systemic skeletal developmental abnormalities (osteogenesisimperfecta), so it is thought that the disease is associated with abnormal mesodermal development. Abrasion may occur, and the dentin is exposed and highly susceptible to wear, as evidenced by the appearance of dentin planes after heavy abrasion. It can be distinguished from hereditary tetracycline dentin by the excitation fluorescence observed in tetracycline teeth with a UV lamp, which can be distinguished from hereditary papillary dentin.
