Abstract

Dental compositions are described which are photocurable by radiation with a wavelength greater than 390 nm. The compositions include a cationically active compound, a dental filler, optionally a dispersant, a cationic photoinitiator and a photosensitizer which is a thioxanthone salt substituted by at least one group containing an ammonium function. The composition has the advantage of remedying the color stability problems of finished dental products after crosslinking.
