DENTAL AND ENDODONTIC FILLING MATERIALS AND METHODS

摘要

Disclosed are endodontic filling materials and methods. A method for filling a dental root canal may include providing a hydrosetting filling material and inserting the hydrosetting filling material into the dental root canal, the material setting in the root canal to form a biocompatible filling. The hydrosetting filling material comprises a hydrogel former and a filler. The hydrogel former is at least one of a reactive organic hydrogel formers, an inorganic hydrogel formers, and a non-reactive organic hydrogel formers, and the filler is at least one of a self-hardening and a non-hardening filler. Plural filling material precursor compositions that collectively contain hydrogel formers and fillers may be provided.

1. A composition for filling a dental root canal, comprising:
a first filling material precursor composition and a second filling material precursor composition for creating a blend of said first and second material precursor compositions, said blend of said first filling material precursor composition and said second filling material precursor composition forming a hydrosetting, biocompatible root canal filling material, said root canal filling material, upon blending and prior to setting, comprising:
a hydrogel material selected from the group consisting of:
(1) a stable hydrogel; and(2) a hydrogel former in a non-aqueous liquid carrier, the hydrogel former selected from the group consisting of reactive organic hydrogel formers, inorganic gel formers and non-reactive organic hydrogel formers, and mixtures thereof, anda filler selected from the group consisting of a self-hardening filler and a non-hardening filler, said root canal filling material characterized as capable of storage without hardening and without forming a hydrogel polymeric mass before blending for in situ disposition in a root canal, said non-aqueous liquid carrier comprising at least about 17% to about 53% by weight of said blend, said filler comprising at least about 26% to about 80% of said blend, and a balance of said blend comprising the hydrogel material, a ratio of said filler to said hydrogel material at least greater than about 3.0.
