Background:

Effective light transmission to the apical region of root canals is crucial for complete resin cement polymerization.
Challenges exist in achieving adequate light penetration for reliable cement adhesion within root canals.

Purpose of the Study:

To compare the cement-polymerizing ability, microstructure, and radiopacity of the iLumi fiber optic post against the DT Light Post.
Evaluate the performance of a novel fiber optic post in simulated root canal environments.

Main Methods:

A modified depth-of-polymerization protocol was employed using a light-polymerized resin cement.
Scanning electron microscopy (SEM) analyzed post microstructure.
Radiopacity was assessed using an aluminum step wedge.

Main Results:

The iLumi fiber optic post exhibited significantly greater polymerized resin cement weight and length.
SEM revealed a higher density of parallel fibers in the iLumi post.
The iLumi post demonstrated superior radiopacity compared to the control fiber post and a titanium alloy post.

Conclusions:

The iLumi fiber optic post possesses a unique fiber composition enhancing light transmission for superior resin cement polymerization.
Its excellent radiopacity and light-transmitting properties surpass those of the DT Light Post.
This suggests improved clinical efficacy for the iLumi post in endodontic restorations.
