Patent ID: 7780449

Claim:
A method for treating a tooth following or during an endodontic procedure comprising: providing a tooth that includes an access hole drilled into and extending through the crown of the tooth, said access hole providing access to at least one root canal of the tooth that has been cleaned by an endodontic procedure; mixing together initially separate parts of a multipart endodontic composition to form a mixed filling and sealing composition which is initially flowable and suitable for placement into a root canal during a root canal procedure and which hardens over time, the mixed composition initially comprising: a polymerizable resin portion contained in at least one of the initially separate parts and consisting essentially of a hydrophilic polymerizable adhesive resin that is at least one of a hydrophilic acrylate or methacrylate capable of bonding to dental tissue found within a root canal and which includes one or more acrylate and/or methacrylate ester linkages, wherein at least a portion of the at least one acrylate or methacrylate is substituted with at least one hydrophilic group in addition to the one or more acrylate and/or methacrylate ester linkages, wherein the at least one hydrophilic group comprises at least one of an oxysulfur radical, borate radical, carboxyl radical, or nitro radical; and a two-part chemical cure system comprised of: at least one peroxide-based component contained in at least one of the initially separate parts; and at least one amino component contained in at least one other of the initially separate parts that does not contain the peroxide-based component; wherein the two-part chemical cure system, upon mixing the initially separate parts together, causes at least a portion of the polymerizable resin portion to polymerize over a period of time; introducing the mixed composition into the at least one root canal of the tooth; allowing the mixed composition to at least partially polymerize and harden within the root canal; and filling the access hole with a filling material.
