摘要： A dental mixing device with a barrel, a mixing tip, and a plunger. The plunger moves dental material through the barrel where it is mixed using a mixing tip. The mixing tip includes an auto-aligning fitting female element configured to align with an auto-aligning fitting male element of the barrel. This auto-alignment simplifies the attachment between the mixing tip and the barrel. The mixing tip also includes a seal component with a soft material (or component) to insert into the auto-aligning fitting element which is a hard material (or component) to achieve seal. The seal component and auto-alignment fitting element can be combined together into one component instead of two components.

摘要： The invention relates to nano-sized complexes formed by associating or attaching amorphous calcium phosphate (ACP) and/or amorphous calcium fluoride phosphate (ACFP) with an amphiphilic polymer surfactant (APS) and a bioadhesive polymer. The bioadhesive polymer may serve as a connector or an anchor to attach the nano ACP-APS or ACFP-APS to the tooth surface and to chemically bond the calcium in the enamel to the calcium ions in the nano ACP-APS or ACFP-APS complexes, thus allowing for more controlled release of remineralizing components into the oral cavity. Methods of use of the composition and kits are also disclosed.

摘要： A dental syringe device that provides air and water to a dental patient. The device includes an adapter that connects a dental tip to a dental syringe body. The dental syringe body provides a conventional syringe body with a handle for a dentist to hold onto and a source of air and water. The tip delivers the air and water to the dental patient. The adapter is an improved adapter having a unique release and attachment component allowing for a quick connect and disconnect between the dental syringe body and the tip. The tip advantageously includes an inner portion with large and uniform air channels for smooth transfer of air and an outer portion made from a rigid plastic that provides an improved cheek retraction feature.

摘要： The invention relates to nano-sized complexes formed by associating amorphous calcium phosphate (ACP) and/or amorphous calcium fluoride phosphate (ACFP) with an amphiphilic polymer surfactant. The amphiphilic polymer surfactants can form nano-sized assemblies in aqueous solution, serving as a nano dispersant preventing ACP and/or ACFP from aggregation, and as a nano carrier associating or attaching ACP and/or ACFP, stabilizing ACP and/or ACFP against the conversion to a crystalline form as well, thus maintaining calcium and phosphate/and fluoride ions in a bioavailable state for dental re-mineralization and prevention of dental caries, dental calculus and dental hyper-sensitivity. A method for the nano-sized complex preparation and compositions comprising the nano-sized complexes are also provided.
