Problems solved by technology

[0027] The embodiment of the present application provides a composition paste for tooth sealing treatment, its preparation method and application. It is difficult to control the hydration and solidification time of the paste, and the shrinkage of the paste after hydration is not conducive to tight filling. A ready-to-use multi-composition paste for tooth sealing treatment. The composition paste can be poured or injected directly, solidifies efficiently, and at the same time achieves anti-microleakage through remineralization, and achieves high-efficiency antibacterial and long-term maintenance according to its chemical composition. Effective anti-infection, anti-inflammation, promotion of tissue repair and other functions

Abstract

The invention provides a composition paste for tooth sealing treatment as well as a preparation method and application thereof. The paste contains a multifunctional active substance component capable of rapidly self-curing, an X-ray blocking agent and a shaping liquid, the inorganic active substance is superfine particles of a mixture of partial hydrates of silicate, phosphate and the like of calcium, magnesium and strontium and bioglass or bioceramic; the shaping liquid is an organic liquid. According to the invention, the active component capable of rapidly self-curing, the X-ray blocking agent and the shaping liquid are premixed to form paste, the paste is filled into an injector, and during application, the paste can be directly injected into root canals, root apex holes and root apex peripheries of teeth and then can be rapidly solidified and seal the area where the paste is located. The method has practical values of preventing and treating bacterial intervention, promoting dental pulp regeneration, inducing remineralization in a root canal system, preventing micro-leakage and tooth sensitivity, promoting periapical tissue repair and the like.

Description

technical field [0001] The application relates to the field of oral care materials, in particular to a composition paste, a preparation method and an application for tooth root canal or periapical sealing treatment. Background technique [0002] Due to poor oral cleaning habits, or various diseases, accidents, etc., any part of the root canal, apical foramen, and periapical area of ​​the tooth will be infected by bacteria, which will cause pain, persistent inflammation, and even tissue necrosis. In general, root canal therapy is the first choice for tooth preservation in irreducible pulpitis, pulp necrosis or periapical disease. However, the effect of root canal treatment depends not only on root canal cleaning, root canal disinfection, etc., but also on whether the root canal filling is tight, especially if the root canal filling is not tight, whether the physical and chemical reactions of the filling material can avoid microleakage or secondary infection. Secondly, peria...
