Stable and substantially filled cationic dental compositions are described which include:
(1) at least one cationically reactive compound (A);
(2) at least one dental filler (B);
(3) optionally, at least one dispersant (C) composed of at least one organic polymer or copolymer;
(4) at least one cationic photoinitiator (D); and
(5) optionally, at least one photosensitizer (E). The dental filler (B) is treated with at least one organosilicon coupling agent (F), and
at least one compound (G). The organosilicon coupling agent (F) has at least one reactive function (rfA) directly linked to a silicon atom forming after activation of a chemical bond with the dental filler, and at least one reactive function (rfB) not directly linked to a silicon atom, forming after activation, a chemical bond with a reactive function (rfC) of the compound (G).
