Background technique

Nowadays, various dental diseases caused by changes in tooth structure due to personal dental habits or oral hygiene are not uncommon. Pulp disease is one of the most common dental diseases, mainly divided into caries and pulp Periapical disease, when the caries develops severely, it will also lead to pulp necrosis and develop into periapical disease of the dental pulp. For endodontic diseases of mature permanent teeth whose roots have fully developed, the main treatment method is root canal therapy.

Root canal therapy is a treatment method for pulp and apical lesions of teeth. It is divided into three parts: pulp removal, root canal shaping preparation, and root canal filling. Common root canal fillings in clinical practice include solid, paste Generally, different filling types are selected according to different filling objects. The principle is to remove most of the infected substances in the root canal through mechanical and chemical methods, and to prevent the occurrence of root apex by filling the root canal and sealing the crown. periapical lesions or promote the healing of periapical lesions that have occurred.

At present, with the advancement of medical science, the selection of fillings for endodontic root canal treatment is becoming more and more extensive. Clinically, a kind of dental pulp stem cells of deciduous teeth have been gradually tried to fill the root canals of teeth, but due to the Dental pulp stem cells themselves are not in good shape, and cannot provide effective support when placed in the root canal, resulting in poor root canal treatment effects. Therefore, there is an urgent need for a mold that can shape the dental pulp stem cells of deciduous teeth, so that the dental pulp stem cells of deciduous teeth can be solidified into the desired shape and placed in the root canal of the tooth to achieve better therapeutic effect.
