COMPOSITION FOR FILLING TEETH Russian patent published in 1997 - IPC

FIELD: medicine; clinical stomatology; production of tooth-filling materials. SUBSTANCE: proposed tooth-filling composition traditionally contains calcium oxide hydrate. Inventive novelty of composition resides in fact that it further contains feedstock used for making aluminofluorosilicate glass; 2,3-bis-(hydroxymethyl) quinoxaline 1,4-di-N-oxide and 40%-aqueous polyacrylic acid solution, said components being taken in following weight ratio, wt. %: Calcium oxide hydrate 3.10-4.60 Aluminofluorosilicate glass feedstock 94.20-96-10 2,3-bis-(hydroxymethyl) quinoxaline 1,4-di-N-oxide 0.10-0.70 Polyacrylic acid in form of 40%-aqueous solution balance. In order to ensure complete reaction between aluminofluorosilicate glass feedstock and polyacrylic acid solution without formation of residual products and to thereby obtain material harmless for patient's teeth, it is recommended to use aluminofluorosilicate glass containing quartz sand, aluminium hydroxide, aluminium orthophosphate, synthetic cryolite, calcium fluoride, and aluminium fluoride, said components being taken in following weight ratio, wt.%: Quartz 16.40-16.80 Aluminium hydroxide 29.30-29.70 Aluminium orthophosphate 12.90-13.30 Synthetic cryolite 16.00-16.40 Calcium fluoride 12.30-12.70 Aluminium fluoride 11.90-12.30. EFFECT: proposed composition possesses all merits of conventional tooth-filling compositions and, in addition, produces bactericidal effect and has self-hardening base, thereby providing good sealing for filled teeth, reducing occurrence rate of recidives and carious complications. 2 cl
