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 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 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.

Abstract: A device, system, and method are directed towards determining a start and/or an end time for a spontaneous event. A mobile device user creates a group for the spontaneous event, and sends the members an invite. During the event, members share media content and/or text messages with other members. Based, in part, on a flow of media content and/or text messages between the members, a determination of a start time and/or end time of the spontaneous event is automatically performed. The start time may be based on when the group is created and/or revised when a flow rate of the media content and/or messages exceed a threshold. The end time may be based on the flow rate being less than another threshold. The location of the spontaneous event may also be determined based on a location of the member's mobile devices during the event.

Abstract: A device, system, and method are directed towards determining a suggested characteristic for an event. At least two events are determined. In one embodiment, at least one characteristic is determined for one of the event. A plurality of other characteristics is determined for the other event. The characteristics of the two events may be determined implicitly from communications during the events or from user input. Based on a relationship between the determined characteristics, the suggested characteristic for the event is then determined. In one embodiment, the relationship is defined as a match of characteristics. The event may then be modified based on the suggested characteristic. For example, a suggested member may be invited to join the event, or the event's time, location, or name may be changed. If the other event is current or pending, the event and the other event may be combined.
