Dental materials and associated methods are described based on multicyclic allyl sulphides with general Formula (I): ##STR00001## in which R.sup.1 is H or a C.sub.1-C.sub.10 alkyl radical; R.sup.2 is H or a C.sub.1-C.sub.10 alkyl radical; R.sup.3 is absent or is a C.sub.1-C.sub.20 alkylene radical which can be interrupted by O or S, a cycloaliphatic C.sub.4-C.sub.12 radical, a bicyclic C.sub.6-C.sub.12 radical, a C.sub.6-C.sub.14 arylene or C.sub.7-C.sub.20 alkylene arylene radical; R.sup.4 is an n-times substituted aliphatic C.sub.2 to C.sub.20 hydrocarbon radical which can be interrupted by O or S, a cycloaliphatic C.sub.4-C.sub.12 radical, an aromatic C.sub.6-C.sub.14 radical, an aliphatic-aromatic C.sub.7-C.sub.20 radical or a heterocyclic radical which can contain 4 to 20 carbon atoms and 1 to 6 heteroatoms which are selected from N, O, P and/or S atoms, or which is formed exclusively by these heteroatoms; R.sup.5 is absent or is a C.sub.1-C.sub.10 alkylene radical; X is absent or is O, S, --O--CO-- or --O--CO--NH--; Y is absent or is O, S, --O--CO-- or --O--CO--NH--; m is 0 or 1 and n is an integer from 3 to 6.
