X-ray visibility especially at the outer margin of the post is significantly improved.

Abstract: A root canal instrument includes a twisted strip having a titanium-nickel alloy or a plastics material. The strip has a cross-section having three exterior surfaces or four exterior surfaces. A coating is disposed on at least one exterior surface, the coating includes abrasive particles. A method of making the root canal instrument includes making a basic plate having a thickness of less than one millimeter, coating the basic plate with a coating having the abrasive particles; dividing the basic plate into longitudinally extended strips, twisting the strip to form a root canal drill bit having a cutting edge with abrasive particles disposed on the cutting edge.

Abstract: A method of manufacturing a dental post according to the present invention comprises the steps of: (i) overjacketing extrusion of at least one thermoplastic material over at least one filament or yarn, such that the thermoplastic material cross-sectionally enwraps the at least one filament or yarn; (ii) solidifying the extruded product of step (i); (iii) equipping the solidified extruded product of step (ii) with a surface texture, such that the thermoplastic wrapping is not modified in a way as to expose or damage the at least one filament or yarn. The invention allows for more flexibility in the manufacturing of dental posts, especially in generating surface textures of such dental posts.

Abstract: The invention relates to an obturation device (1) for blocking an apical foramen of a root canal of a tooth by means of an obturation plugging mass. The obturation device (1) has a carrier (5), wherein the obturation plugging mass is arranged in slidingly displaceable manner, and has an applicator (6), by means of which the obturation plug (4) comprising obturation plugging mass is applied in the apical foramen. The applicator (6) has a housing (7) with a pushing mechanism (8), which mechanism is arranged to be brought into engagement with the carrier (5) and pushes the obturation plugging mass from the carrier (5) into the apical foramen.

Abstract: The invention concerns a method of retraction of sulcus, in which, in a first step, a flowable retraction material (1) is applied onto the sulcus (5) of at least one tooth (4). In a second step, a dental dam (2) is applied onto the tooth (4) and brought into contact with or in the vicinity of the retraction material (1). According to the invention, the retraction material (1) and the material of the dental dam (2) are chosen such that they can form a chemical bond with each other. Moreover, the invention concerns a dental kit (9) for performing the method, which dental kit (9) contains at least one flowable retraction material (1) and at least one dental dam (2), wherein the retraction material (1) and the dental dam (2) can form a chemical bond. Additionally, the invention concerns the use of a dental kit (9) in the method. Finally, the invention concerns a dental retraction device (10) containing a retraction material (1) and a dental (2), which have formed a chemical bond with each other.
