Abstract
An apical portion of a root canal is cleaned with an abrading portion of a file that has a taper that is greater than 0.20. Once the apical portion has been cleaned with an abrading portion that is greater than 0.20, such as 0.25, then an endodontic point, such as a gutta percha point can be easily received in the apical portion of the root canal to seal the apex. It is optimal to utilize a set of instruments. All of the instruments may have files with abrading portions that are greater than 0.25. However, only the larger files need have such abrading portions since they are the last to be used when cleaning the apical portion.
Claims24
A method for cleaning the apical root portion of an operative root canal of a tooth, the method comprising:
- selecting an endodontic point having a taper;
- obtaining at least one apical portion cleaning instrument that has a file with an abrading portion for removing pulp material, the file having a taper that is greater than the taper of the endodontic point;
- and
- cleaning the apical root portion with the at least one apical portion cleaning instrument by abrading the apical root portion with the abrading portion of the file such that the apical root portion is prepared so as to have a taper that is greater than the taper of the endodontic point.
A method for cleaning the apical root portion of the operative root canal of a tooth, the method comprising:
- selecting an endodontic point having a taper of 0.02;
- obtaining a set of apical portion cleaning instruments that each have a file with an abrading portion for removing pulp material, wherein at least one of the apical portion cleaning instruments has an abrading portion with a taper that is greater than the taper of the endodontic point;
- and
- cleaning the apical root portion with one or more of the apical portion cleaning instruments such that the instrument that is last to be used in the apical root portion has an abrading portion with a taper that is greater than the taper of the endodontic point to enable the cleaned apical root portion to more easily receive the endodontic point compared to a cleaned apical root portion having a taper that equals the taper of the endodontic point.
A method for performing a root canal procedure, the method comprising:
- selecting an endodontic point having a taper of 0.02;
- obtaining at least one apical portion cleaning instrument that has a file with an abrading portion for removing pulp material, the file having a taper that is greater than 0.02;
- and
- cleaning the apical root portion with the at least one apical portion cleaning instrument by abrading the apical root portion with the abrading portion of the file such that the apical root portion has a taper greater than 0.02;
- introducing the endodontic point into the cleaned apical portion of the root canal.
An endodontic system for preparing an apical root portion of an operative root canal of a tooth, the system comprising:
- an endodontic point having a taper;
- and
- an apical portion cleaning instrument comprising a file having a length that is sufficient to extend to the apex of a root canal, wherein the file has an abrading portion extending from a tip of the file upward with sufficient length to enable at least the apical portion of a root canal to be abraded, wherein the abrading portion has a taper that is greater than the taper of the endodontic point such that an apical root portion of a tooth that is cleaned using the apical portion cleaning instrument will have a taper that is greater than the taper of the endodontic point.
An endodontic system for preparing an apical portion of a root canal of a tooth comprising:
- one or more endodontic points having a taper of 0.02;
- and
- a set including a plurality of apical portion cleaning instruments adapted for cleaning the apical root portion of the operative root canal of a tooth, each instrument in the set having a file with a length that is sufficient to extend to the apex of a root canal, wherein each file has an abrading portion extending from a tip of the file upward with sufficient length to enable at least the apical portion of a root canal to be abraded, wherein the file of at least one of the instruments has an abrading portion with a taper that is greater than 0.02 so that the abrading portion with a taper greater than 0.02 can be used to clean an apical root portion so as to have a taper that is greater than 0.02 to thereby enable the cleaned apical root portion to more easily receive the endodontic point having a taper that is 0.20 compared to a cleaned apical root portion having a taper of 0.02.
