Abstract

The invention relates to a calcium hydroxide root canal disinfection paste and a preparation method thereof, belonging to the technical field of oral care. In order to solve the problems of poor stability and easy early absorption and diffusion of existing calcium hydroxide pastes, the present invention provides a calcium hydroxide paste for root canal disinfection. The components include calcium hydroxide, clove basil oil, bioactive glass, water-soluble polymers, X-ray opaque fillers, solvents, and purified water. In the calcium hydroxide root canal disinfection paste provided by the present invention, the colloidal polymer formed by the water-soluble polymer and the solvent can completely wrap the calcium hydroxide solid, which can not only increase the calcium hydroxide content in the disinfection paste, but also improve its disinfection effect. It can also improve the stability of the disinfection paste, and adjust the absorption and diffusion speed of calcium hydroxide by controlling the dissociation speed of hydroxyl groups. The disinfectant paste of the present invention has stable and long-lasting antibacterial and antiviral effects when applied to root canal treatment, can reduce the probability of secondary pollution, and relieve irritation and pain.

Description

technical field [0001] The invention belongs to the technical field of oral care, and in particular relates to a calcium hydroxide root canal disinfection paste and a preparation method thereof. Background technique [0002] Root canal therapy, also known as endodontic therapy, is an operation in dentistry to treat pulp necrosis and root infection. The main goal is to remove bacteria, biofilm, seal the root canal to prevent infection, and promote the healing of the periapical tissue. Root canal treatment consists of three stages: root canal preparation, disinfection and filling. Due to the complexity of the root canal system, conventional mechanical preparation can only remove most of the infected tissue, but cannot completely remove it, and the remaining bacteria and toxins in the deep dentin tubules and side branch root canals rely solely on manual instruments or machine-use nickel-titanium instruments Still difficult to remove. Therefore, root canal disinfection plays a...
