This study was designed to assess the ability to prevent glucose penetration of a bioceramic putty ready-to-use repair cement comparing to white mineral trioxide aggregate (WMTA). After root canal instrumentation, the apical 3 mm of maxillary incisors were resected and root-end cavities with depth of 3 mm were prepared with ultrasound and filled with the tested materials (15 roots per group). All roots were mounted in a double chamber system to assess glucose penetration using 15 psi pressure application. After 1 h, glucose concentrations in the lower chamber were measured following an enzymatic reaction. Four roots were used as controls. The Mann-Whitney test verified differences in glucose leakage between groups and the Tukey's test was used for multiple comparisons. Significance level was set at 5%. There was no significant difference in glucose leakage between iRoot BP Plus and White MTA groups. iRoot BP Plus had a similar ability to that of white MTA in preventing glucose leakage as a root-end filling material.

En 1998 el Hospital Clínico Universitario de Barcelona inició un proceso de reorganización interna general, aplicando un modelo de rediseño de la atención basado en procesos asistenciales centrados en el paciente (Proyecto Prisma). La identificación de grupos homogéneos de pacientes, tributarios de ser atendidos conjuntamente por un grupo de servicios asistenciales médicos y quirúrgicos organizados a su alrededor (institutos de gestión clínica), según sus necesidades clínicas y consumo equivalente de recursos, constituye su componente organizativo más destacado 1 . Así, de 44 servicios se pasó a 12 institutos y 2 centros. Los institutos están dotados de autonomía de gestión y, entre otros objetivos, pretenden hacer un uso más racional de los recursos asistenciales.
