Abstract
Los objetivos del presente estudio son los siguientes: 1. Comparar la resistencia mecánica del Biodentine (BD), Totalfill Root Repair Materials Pasta (TRRM) y ProRoot MTA White (MTA) empleados en cavidades de dentina de un espesor de tres y cinco milímetros. 2. Comparar la fuerza promedio necesaria para romper la unión al diente de los materiales biocerámicos estudiados y su resistencia mecánica en espesores de tres y cinco milímetros. 3. Valorar la predictibilidad de los tres cementos. 4. Describir el tipo de fractura (adhesiva, cohesiva, mixta) que se produce al llevarse a cabo el ensayo mecánico de push-out.
The objectives of the present study are the following: 1. To compare the push-out bond strength of biodentine (BD), Totalfill Rooth Repair Material (TRRM) and ProRoot MTA White (MTA) in dentine cavities of three and five millimetres of thickness. 2. To compare the maximum force required to break the bond to th tooth of the three bioceramic materials and their mechanical strength in dentine thickness of three and five millimetres. 3. To determine the type of failure pattern (adhesive, cohesive, mixed) which occur once the mechanical push-out test is carried out.
