The disclosure relates to oral delivery compositions that transition from a flowable state to a hardened or semi-hardened state. The flowable hardening composition may be delivered to oral tissues, including teeth and/or gums, directly or using a barrier strip or a tray-like device. Such compositions may be configured as a multi-part system wherein reactive materials (e.g., catalyst and reactive resins) are kept separate until use. Dispersion of the agents in a viscous carrier within the hardened composition enables a gradual release the desired agent(s) to reduce or eliminate sensitivity that may be caused by certain agents (e.g., dental whitening agents). The hardened delivery composition may include a reverse image of the oral tissue, allowing it to be removed and replaced multiple times during a single use, giving users more flexibility during treatment.

Compositions, systems, and methods for oral delivery

Dental compositions (e.g., adhesives, cements, primers, sealants, and etchants) and related methods of use are disclosed herein. The dental compositions can include diamond particles. The diamond particles can have an average size of below 10 microns. In some instances, the dental adhesives can act as a one-part dental adhesive, and can be configured to remove portions of the smear layer and act as an adhesive or bonding agent.

Dental compositions and related methods of use

Dental cement compositions (including two-part compositions), kits, and related methods are used for bonding a dental prosthetic appliance to a tooth. A first part includes an amine activator component and a zinc oxide reactive filler, while a second part includes a polymerization initiator (e.g., benzoyl peroxide) and a polymerizable component having a structure including at least one acrylate or methacrylate group at one end and a carboxylic acid group at another end. A temporary cement composition advantageously exhibits reduced compressive and/or bonding strength relative to permanent cement compositions, which provides sufficient strength to facilitate normal use of the teeth while the provisional appliance is in use, while also facilitating easy removal of the provisional appliance for replacement with a permanent appliance at a later time.

Resin reinforced zinc polycarboxylate temporary cement compositions and related kits and methods

Two-part resin-reinforced cement compositions, kits, and related methods are used for bonding a dental prosthetic appliance to a tooth. A first part includes an amine activator component and a zinc oxide reactive filler, while a second part includes a polymerization initiator (e.g., benzoyl peroxide) and a polymerizable component having a structure including at least one acrylate or methacrylate group at one end and a carboxylic acid group at another end. A temporary cement composition advantageously exhibits reduced compressive and/or bonding strength relative to permanent cement compositions, which provides sufficient strength to facilitate normal use of the teeth while the provisional appliance is in use, while also facilitating easy removal of the provisional appliance for replacement with a permanent appliance at a later time.

Fluoride varnish compositions for temporary application and adhesion to a person's teeth. The composition includes a carrier comprising a resin and an adhesion promoting agent comprising an alkyl phosphoric acid. A fluoride ion source (e.g., a fluoride salt such as sodium fluoride) is dispersed within the carrier so as to provide biologically available fluoride ions to the tooth tissue being treated. The composition adheres only temporarily to tooth tissue (e.g., for a period of at least about 4 minutes, but not more than about 1 year), after which the composition spontaneously wears away as a natural result of the action of the tongue, saliva and/or other factors.
