El objetivo del presente estudio es determinar la microfiltración de tres biocerámicos indicados para reparar perforaciones laterales iatrogénicas, teniendo en cuenta el tiempo de fraguado. El grupo de estudio estuvo conformado por 80 dientes humanos extraídos con fines ortodónticos y periodontales, los cuales fueron divididos aleatoriamente en cuatro grupos y tres de ellos en dos subgrupos según el tiempo de fraguado del biocerámico: grupo A: MTA Repair HP (A1: MTA Repair HP, fraguado por 24 horas, A2: MTA Repair HP, fraguado por 0 horas), grupo B: Biodentine (B1: Biodentine, fraguado por 24 horas, B2: Biodentine, fraguado por 0 horas), grupo C: NeoMTA 2 (C1: NeoMTA 2, fraguado por 24 horas, C2: NeoMTA 2, fraguado por 0 horas), grupo D: control negativo. Las muestras fueron perforadas, reparadas con biocerámicos, expuestas a azul de metileno al 1%, cortadas y observadas en el estereoscopio
para finalmente ser medidas a través de referencias milimétricas. Se encontró que existe diferencias significativas al comparar la filtración entre biocerámicos; pero no hay diferencias significativas al relacionar cada bioceramico según su tiempo de fraguado. Se concluye que cada bioceramico, presenta distintos valores de microfiltración y el tiempo de fraguado es independiente a su capacidad de sellado. / The objective of this study is to determine the microleakage of three bioceramics indicated for repairing iatrogenic lateral perforations, taking into account the setting time. The study group was made up of 80 human teeth extracted for orthodontic and periodontal purposes, which were randomly divided into four groups and three of them into two subgroups according to their repair with bioceramics: group A: MTA Repair HP (A1: MTA Repair HP, setting for 24 hours, A2: MTA Repair HP, setting for 0 hours), group B: Biodentine (B1: Biodentine, setting for 24 hours, B2: Biodentine, setting for 0 hours), group C: NeoMTA 2 (C1: NeoMTA 2, setting for 24 hours, C2: NeoMTA 2, setting for 0 hours), group D: negative control. The samples were drilled, repaired with bioceramics, exposed to 1% methylene blue, cut and observed in the stereoscope to finally be measured through millimeter references. It was found that there is a statistically significant difference when comparing microfiltration between bioceramics; but there are no significant differences when relating each bioceramic according to its setting time. It is concluded that each bioceramic presents different microfiltration values and the setting time is independent of its sealing capacity.
