摘要： A method and system for inserting a dental post (51) into a tooth root canal is provided. The method comprises the steps of cutting out a post hole (17) in the tooth (11) and inserting a threaded tap (19) into the post hole (17) for creating at least one groove (45) along the hole (17). Significantly, the tap (19) includes at least one slot (31) defined by a pair of flexible legs (27, 29) and running at least a portion of the length thereof for reducing stress along the post hole (17) during threaded insertion. Also provided is a lentulo drill (37) comprising a spiraled wire (41) with a reverse spiral configuration at the apical end (43) thereof for confining cement placement in the post hole (17) prior to insertion of the dental post (51).

摘要： A method and system for preparing a cast post and core in a dental root canal procedure is provided. The method comprises the steps of removing the root canal material from the tooth (49); cutting out a posthole (47) in the tooth having a substantially uniform width; cutting out at least one annular tier (56) along the hole (47); placing a burnout post (61) having at least one flange (67) into the posthole (47) so that the flange (67) is seated on the annular tier (56); applying an acrylic resin onto the tooth and over the burnout post (61) in order to form a core (75), and finally removing the core (75) with the burnout post (61) from the tooth in order to form a casting.

摘要： An endodontic instrument includes a cutting portion having upper and lower ends spaced apart along an axis, a cutting surface extending helically along the axis, and a non-contact surface extending helically along the axis. A cross section of the cutting portion in a plane perpendicular to the axis has a non-circular circumference. The cutting surface extends about a first portion of the non-circular circumference, and the non-contact surface forms a linear segment that extends about a second portion of the non-circular circumference. The cutting portion can further include a second cutting surface extending helically along the axis, and a second non-contact surface extending helically along the axis.

摘要： A non-circular endodontic instrument (110) is provided for reduced stress to the tooth, and to the cutting instrument during the removal of dentin from a root canal. The non-circular endodontic instrument (110) includes at least one area of non-contact (140), i.e., one portion of the instrument does not contact, and does not cut the dentin material. The non-contact area (140) extends the length of the endodontic instrument (110), about a portion of the circumference of the instrument, and interrupts a generally circular cutting face (120) of the instrument. This non-contact area (140) reduces stress, provides a place for debris to gather during cutting so as to not interfere with the cutting face (120), and serves to direct the debris out of the root canal. The endodontic instrument (110) can be D-shaped in cross-section. It could have circumferential opposing non-contact, areas and/or can be elliptical in cross-sectional shape.

摘要： A composition for endodontically treating a root canal is provided. The composition uses a thermoset resin based material adapted for insertion into the root canal of a dental patient and an adhesive material suitable for maintaining the polymer based material in the root canal. Either one or both of the thermoset resin based material and the adhesive material is conductive. As a result, the dental practitioner is able to determine where the apex of the root canal is located by means of measuring the conductance between the thermoset resin based material and the oral mucosa and periodontal ligament. This facilitates the filling of the root canal with the polymer based material.
