Refers to a dental Cement Composition of Mineral TRIOXIDE aggregate (MTA) regenerative, comprising: (a) pozzolanic Portland Cement Type I (composed of tricalcium silicate, dicalcium silicate (3cao\u2013sio2) (2cao\u2013sio2), tricalcium Aluminate (3cao\u2013al2o3), tetracalci FERRIC Aluminate Co (4cao\u2013al2o3\u2013fe2o3) and calcium sulphate (CaSO4) (b) zirconium oxide (ZrO2) and (c) iodophor (chi3).In a Preferred aspect, the composition comprises a Regenerative dental Cement particle size below 150 micrometres. Also relates to a kit comprising Said Composition of Regenerative dental Cement and harmless Solvent which allows setting (preferably Water).The Composition of the invention is useful for Regenerative Treatment of root caries lesion, perforations, or Sealing of Holes created by endodontic Instruments, among others.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.
