Summary
Human osteoblasts show better adhesion to mineral trioxide aggregate (MTA) and composite resins compared to IRM and amalgam. This suggests MTA and composite are more favorable root-end filling materials for bone cell growth.
Area of Science:
- Biomaterials Science
- Cell Biology
- Dental Materials
Background:
- Root-end filling materials are crucial for endodontic treatment success.
- Understanding osteoblast adhesion to these materials is vital for bone regeneration.
- Mineral trioxide aggregate (MTA), IRM, composite, and amalgam are commonly used materials.
Purpose of the Study:
- To evaluate and compare the adhesion and spreading of human osteoblasts on four different root-end filling materials.
- To determine the biocompatibility of MTA, IRM, composite, and amalgam concerning osteoblast interaction.
Main Methods:
- Human osteoblasts were cultured on disk-shaped samples of MTA, IRM, composite, and amalgam.
- Cell adhesion and morphology were examined using scanning electron microscopy after 1 day of culture.
Main Results:
- Osteoblasts readily attached and spread on mineral trioxide aggregate (MTA) and composite, forming a monolayer.
- Attachment was observed on amalgam, but with limited cell spreading.
- Osteoblasts remained rounded with no spreading on IRM, indicating poor adhesion.
Conclusions:
- Mineral trioxide aggregate (MTA) and composite resin demonstrate superior osteoblast adhesion and spreading compared to IRM and amalgam.
- MTA and composite are favorable root-end filling materials for promoting osteoblast response and potential osseointegration.
