It refers to a kind of compound of reclaimed mineral nitrogen trioxide (MTA) dental cement, including: (a) Portland puzolanico type I cement (composed of calcium silicate (3cao-sio2),Silicate (2cao-sio2),Tricalico aluminum (3cao-al2o3),2. Ferrico tetracalico aluminum (4cao-al2o3-fe2o3)；2. Casoo 4；(b) Zirconia (ZrO2)；（c）Yodoformo（CH3）。 In a preferred aspect, the composition of the recycled dental cement includes a particle size of less than 150 microns, and also refers to a package, which includes the composition of the recycled dental cement, and a safe solvent to enable it to form (preferably water). The regeneration component of the invention is useful for processing the perforation seal caused by radiation perforation, tooth decay or endocrine device.Se refiere a una composicion de cemento dental de trioxido mineral agregado (MTA) regenerativo, que comprende: (a) cemento Portland puzolanico tipo I (compuesto por silicato tricalcico (3CaO–SiO2), silicato dicalcico (2CaO–SiO2), aluminato tricalcico (3CaO–Al2O3), aluminato ferrico tetracalcico (4CaO–Al2O3–Fe2O3), y sulfato de calcio (CaSO4))； (b) oxido de zirconio (ZrO2)； y (c) yodoformo (CHI3). En un aspecto preferido, la composicion de cemento dental regenerativo comprende un tamano de particulas por debajo de 150 µm. Tambien se refiere a un kit que comprende dicha composicion de cemento dental regenerativo, y un disolvente inocuo que permite su fraguado (preferentemente agua). La composicion regenerativa de la invencion es util para el tratamiento de perforaciones radiculares, lesion por caries, o sellamiento de perforaciones creadas por instrumentos endodonticos, entre otros.
