Micro-CT Assessment of Hydraulic Calcium Silicate Cements for Perforating Internal Resorption in 3D-printed Tooth Replicas at Different Root Thirds: An In Vitro Study

Why it matters for dental
Endodontists and restorative dentists managing internal root resorption can use this micro-CT data to select the hydraulic calcium silicate cement with the lowest voids and best adaptation when perforations occur in different root thirds.
Key points
- The study used 3-D printed replicas to compare three hydraulic calcium silicate cements in coronal, middle, and apical third perforations.
- Micro-CT quantified internal voids and adaptation at the perforation site, providing objective metrics beyond conventional radiographs.
- Findings can guide material choice in cases where traditional MTA or bioceramic putties are considered interchangeable.
- Published in the Journal of Endodontics (Sept 2026); results are immediately applicable to perforation-repair protocols in both specialist and general practice.
