Abstract: A dental post includes a composite material such as long fibers embedded in a resin matrix, and is able to transmit visible radiation when it is lit by a dental lamp to ensure polymerization of a product for setting in a tooth's root canal. The post, which has a specific color determined at ambient temperature before insertion into said canal, and which contains at least one thermochromic substance able to provide said specific color, loses its color when in place in the canal. A method for forming the dental post and a kit including a plurality of dental posts and drills are also disclosed.

Abstract: Prosthetic dental element is obtained by machining a rod of composite material including fibres embedded in a matrix containing resin. The matrix also contains at least one agent with an antimicrobial effect at a concentration between 0.05 and 30% by weight of the prosthetic element. The agent is in powder form.

Abstract: Dental post made of a composite material contains a central core constituted of a resin matrix in which fibres are embedded. The core is surrounded by a sheath. The sheath is free of fibres and contains at least one substance which can make the post radiopaque.

Abstract: Prosthetic dental element is obtained by machining a rod of composite material made of fibres embedded in a matrix containing resin. All or part of a surface of the machined rod is coated with at least one layer containing at least one agent with an antimicrobial effect.
