A compact material testing system is configured to expose multiple samples housed within separate sample chambers to simulated fluid, thermal, and mechanical loading conditions. The system includes multiple independent load actuators positioned to extend actuator rods into corresponding sample chambers to apply mechanical loading to the test sample within. A fluid control system is included to bathe each test sample in a fluid medium and replenish the fluid medium within its sample chamber as needed. Each sample chamber includes a gas inlet and gas outlet to provide non-turbulent circulation and control of atmospheric composition above the fluid medium inside the chamber. A logic programmable controller is provided for input of test parameters and automated simultaneous control of mechanical loading, fluid flow, and temperature in the sample chambers.

Compact material testing system

Provided are compositions useful as dental adhesives comprising an acrylamide compound, a methacrylate base monomer, a polymerization initiator, and a polymerization inhibitor or a polymerization stabilizer.

Methacrylamide adhesive systems

Disclosed is a method for filling a root canal in a tooth. The method includes positioning a fiber in the root canal of the tooth, filling at least a portion of the root canal with an unset hydrogel composition, such that the unset hydrogel composition contacts at least a portion of the fiber, setting the hydrogel composition, thereby forming a set hydrogel, and removing the fiber from the set hydrogel, thereby leaving a channel in the set hydrogel. Methods and kits for repairing teeth are also described.

Dental pulp construct

The present invention provides tertiary amine core-bearing acrylamides and their use in adhesive formulations, particularly including dental adhesives.

Tert-amine core-bearing acyrlamides and adhesive formulations

New methacrylate compounds are disclosed as well as compositions comprising the methacrylate compounds and thiourethane oligomers. These compositions can be used in, for example, dental composites.

Methacrylamide compounds

Disclosed herein are methacrylate compounds that can be used as components of dental composites. Also disclosed are dental composites comprising the compositions and thiourethane oligomers.
