Claim:
A method of performing a dental procedure, comprising: applying a curable dental composition to tissue of a patient for sealing a root canal, wherein said curable dental composition comprises: (a) a monomer component comprising (a1) one, two or a plurality of polymerizable monomers with a molar mass of less than 4,000 g/mol selected from the group consisting of compounds (monomers) with the structure Q(Y x Z e ) b , wherein the following applies: Q represents a saturated or olefinically unsaturated polyalicyclic structure element selected from the group consisting of bicyclic, tricyclic, tetracyclic, pentacyclic and hexacyclic hydrocarbon radicals, wherein optionally one, two or a plurality of the hydrogen atoms of this polyalicyclic structure element Q not substituted by substituents Y x Z e are substituted by alkyl groups, alkoxy groups, halogen atoms or trifluoromethyl groups, b is an integer selected from the group of integers 2, 3 and 4, each Z represents a structure element, which independently of any other structure elements Z is selected from the group consisting of —O—(C═O)—CH═CH 2 , —O—(C═O)—C(CH 3 )═CH 2 , —(C═O)—CH═CH 2 , —(C═O)—C(CH 3 )═CH 2 , —CH═CH 2 , —C(CH 3 )═CH 2 and —O—CH═CH 2 , each index e is an integer, which independently of any further indices e is selected from the group of integers 1, 2, 3 and 4, each index x independently of any further indices x represents 0 or 1, each Y in the structure Q(Y x Z e ) b where x=1 represents a structure element, which bonds the polyalicyclic structure element Q with e structure elements Z, wherein each Y is selected independently of any further structure elements Y, wherein at least one x=1 and at least one Y comprises a structure element selected from the group consisting of amine, N-acyl urea, allophanate, biuret, and amide, wherein the amide function is not directly linked with an N atom, an O atom or a carbonyl group, and (a2) one, two or a plurality of further polymerizable monomers from the group consisting of acrylates and methacrylates with a polyether structure element, wherein none of these further polymerizable monomers is one of those with the structure Q(Y x Z e ) b according to the definition (a1), wherein the ratio of the total weight of the (a1) polymerizable monomers to the total weight of the (a2) one, two or a plurality of further polymerizable monomers from the group consisting of acrylates and methacrylates with a polyether structure element is in the range of 1:3 through 3:1, (b) one or a plurality of initiators and/or catalysts, and (c) a filler component comprising (c1) one, two or a plurality of radiopaque fillers, and optionally one or a plurality of further additives.
