Infusion type deciduous teeth root canal cataplasm

Abstract

The invention discloses an injection type deciduous tooth root canal paste which is applicable to the treatment of primary teeth pulp diseases and periapical diseases of children, the paste can not be solidified during the long-term storage in a closed container and can be directly filled in a root canal. The components of the formula of the injection type deciduous tooth root canal paste are that: powder contains the following components according to weight percentages: 80 to 94 percent of zinc oxide powder; 4.6 to 19.6 percent of iodoform powder; 0.2 to 0.6 percent of dexamethasone powder and 0.2 to 0.5 of percent metronidazole power; liquid contains 40 to 60ml of propylene glycol in each 100g of the powder. The deciduous tooth root canal paste is mixed into the even paste by stirring according to a conventional method and is contained in a disinfected disposable plastic syringe for standby.

Description

technical field [0001] The invention relates to the technical field of dental materials, in particular to an injection-type deciduous root canal paste. Background technique [0002] Root canal paste, also known as root canal filling, is an indispensable material for the treatment of pulp disease and periapical disease. The root canal of the affected tooth is mechanically prepared and chemically sterilized, and the root canal is filled with root canal paste to isolate the communication between the root canal and the periapical tissue, prevent reinfection, and promote the healing of the apical tissue. The performance and function of root canal paste have an important influence on the curative effect of periapical disease. So far, there is no special root canal paste for the treatment of children's deciduous apical diseases in the domestic market. Clinicians use adult root canal pastes to treat children's deciduous pulp and periapical diseases, or use commonly used materials t...

Problems solved by technology

[0011] ① Disadvantages of the mixing method: the existing commercially available root canal pastes are packaged in two components of powder and liquid before mixing, and need to be mixed temporarily for each use, which is inconvenient to use; generally, doctors need nurses or Dental assistant assists in mixing, otherwise it will affect the quality of root canal filling

[0012] ②Disadvantages in clinical application: a. Due to the short solidification time of the above-mentioned root canal paste, the paste needs to be slowly fed in with the help of root canal instruments during filling, which makes it difficult to fill the root canal tightly, thereby affecting the quality of filling; The solidification time is only enough for a general skilled doctor to operate a tooth (about 30 minutes). If the operation time is prolonged, a new root canal paste should be mixed

b. The above-mentioned root canal paste is not suitable for the treatment of children's deciduous pulp disease and periapical disease. Since the paste needs to be fed slowly with root canal instruments, the operation time is long, and it is difficult for children to cooperate; in addition, it is difficult to mix it into a paste After contact with water, the solidification speed is accelerated, and the sealing effect with the root canal wall is poor. It is difficult to keep the root canal dry for a long time when treating children.

[0013] Because the liquid component of the above-mentioned root canal paste is mostly phenolic, which has a strong irritating smell, it is unbearable for children. It has been reported that phenolic can induce mutations in tissue cells and thus have the risk of carcinogenesis
