Abstract: The present invention relates to oral composition and the method of preparation and use of such composition for inhibiting, reducing, and/or disrupting oral biofilm. The composition comprises a stabilizing matrix, a cationic biocide, and a peroxide source.

Abstract: The present disclosure discloses the application of calcium aluminate in pre-mixed dental filling materials, the pre-mixed dental filling materials themselves, and their preparation methods. In the pre-mixed dental filling materials of the present disclosure, calcium aluminate is used as the primary hydraulic setting material, supplemented by calcium oxide as a curing accelerator and expansion agent, and may also include calcium pyrophosphate. The resulting material is a biologically hydraulic paste with excellent injectability. This material remains fluid under sealed conditions and hardens upon hydration when placed in a physiological environment and exposed to physiological fluids. The disclosure leverages the excellent biocompatibility and bioactivity of calcium aluminate to prepare pre-mixed aluminate hydraulic dental filling materials, which can be used for medical and dental applications, including pulp capping, root canal therapy, and hard tissue repair.

Abstract: The present disclosure discloses a disinfectant and a disinfection method for effectively killing endospores. The disinfectant includes a certain amount of polyhexamethylene biguanide as an active ingredient to kill endospores of Bacillus subtilis var. niger. The disinfectant can effectively kill endospores at room temperature and the atmospheric pressure. The disinfectant can be used for disinfection in environments including hospitals, crowded places, enclosed spaces, public transportation, and livestock and poultry breeding farms.

Abstract: The present disclosure relates to a carrier for sustained-release of a drug and use thereof. The carrier is used to carry a drug. The carrier is in a gel state, a semi-solid state, or a solid state. The carrier includes a polyol fatty acid ester as a main component and a hydrogenated vegetable oil dissolved in the polyol fatty acid ester. The state of the sustained-release carrier can be adjusted by adjusting the amount of the dissolved hydrogenated vegetable oil.
