Abstract
Methods for sealing a root canal using sealant or other filling materials. The compositions may include one or more resins that promote adhesion to hydrophilic dental tissues. The compositions are introduced into the root canal using a narrow cannula coupled to a high pressure hydraulic delivery device. In the case where a chemical cure composition is used to seal the root canal, a chemical initiator can be used to cause the mixed composition to harden over time. Hardening of at least a portion of the composition can be accelerated by including a photoinitiator and irratiating the mixed composition with radiant energy (e.g., from a dental curing lamp).
Claims22
A method for filling and sealing a root canal during an endodontic procedure comprising:
- providing a tooth that includes an access hole through the crown of the tooth, said access hole providing access to at least one root canal of the tooth that has been treated by an endodontic procedure, the at least one root canal terminating at an apex;
- placing a cannula into the root canal so that a tip of the cannula is near the apex of the root canal;
- expressing an endodontic filling and sealing composition from the tip of the cannula so as to begin filling the root canal with the composition;
- and
- continuing filling the root canal with the filling and sealing composition while withdrawing the cannula from the root canal in order to minimize formation of air pockets or bubbles as the composition is progressively placed within the root canal.
A method for filling and sealing a root canal during an endodontic procedure comprising:
- providing a tooth that includes an access hole through the crown of the tooth, said access hole providing access to at least one root canal of the tooth that has been treated by an endodontic procedure, the at least one root canal terminating at an apex;
- placing a cannula into the root canal so that a tip of the cannula is near the apex of the root canal;
- expressing a hydrophilic endodontic filling and sealing composition from the tip of the cannula so as to begin filling the root canal with the composition, the hydrophilic endodontic filling and sealing composition being at least one of chemical cure or photo cure;
- and
- continuing filling the root canal with the filling and sealing composition while withdrawing the cannula from the root canal in order to minimize or eliminate formation of air pockets or bubbles as the composition is progressively placed within the root canal.
A method for filling and sealing a root canal during an endodontic procedure comprising:
- providing a tooth that includes an access hole through the crown of the tooth, said access hole providing access to at least one root canal of the tooth that has been treated by an endodontic procedure, the at least one root canal terminating at an apex;
- mixing together initially separate parts of a chemical cure hydrophilic endodontic filling and sealing composition;
- placing a cannula into the root canal so that a tip of the cannula is near the apex of the root canal;
- expressing the chemical cure hydrophilic endodontic filling and sealing composition from the tip of the cannula so as to begin filling the root canal with the composition;
- continuing filling the root canal with the filling and sealing composition while withdrawing the cannula from the root canal in order to minimize or eliminate formation of air pockets or bubbles as the composition is progressively placed within the root canal;
- and
- allowing at least a portion of the filling and sealing composition to chemically cure.
