# Microleakage and bond strength analysis of zirconia-reinforced fiber posts using different resin cements in endodontically treated teeth

## TL;DR

This study compares how well different resin cements work with zirconia-reinforced fiber posts in treated teeth, focusing on leakage and bond strength.

## Contribution

The study introduces new insights into the performance of various resin cement systems with zirconia-reinforced fiber posts in endodontically treated teeth.

## Key findings

- Self-adhesive resin cements showed the least microleakage, indicating better sealing.
- Total-etch systems had the highest push-out bond strength, especially in the coronal region.
- Bond strength decreased from coronal to apical regions across all cement types.

## Abstract

Microleakage and push-out bond strength of zirconia-reinforced fiber posts cemented with three resin cement systems in endodontically
treated maxillary central incisors is of interest. Ninety extracted teeth were divided into three groups based on the use of
self-adhesive, self-etch and conventional total-etch resin cements. Self-adhesive resin cements showed the least microleakage,
indicating superior sealing ability. Total-etch systems exhibited the highest push-out bond strength, particularly in coronal regions.
Bond strength decreased progressively from coronal to apical regions across all cement groups.
