Definitions
- the present invention relates to a light-polymerizable dental composition comprising a specific inhibitor. Moreover, the present invention also relates to the use of specific fullerene compounds in a dental composition.
- Light-polymerizable dental compositions comprise a polymerizable monomer, a light-sensitive polymerization initiator, and optionally further components such as an organic or inorganic filler or an organic or inorganic pigment. It is known to use a stabilizer for preventing a composition containing polymerizable acrylates and/or methacrylates from spontaneous polymerization. 2,6-Di-tert-butyl-4-cresol (BHT), hydroquinone or hydroquinonemonomethylether (HQME) are known as free radical savengers for dental compositions.
