Optimization of Sodium Iodide-Based Root Filling Material for Clinical Applications: Enhancing Physicochemical...

Area of Science:

• Dental Materials Science
• Pediatric Dentistry

Background:

• Premature loss of root canal-treated primary teeth is a significant clinical concern.
• Traditional iodoform-based materials have limitations.
• A novel sodium iodide-based material was developed to improve root canal filling in primary teeth.

Purpose of the Study:

• To enhance the physicochemical properties of a sodium iodide-based root canal filling material for clinical application.
• To evaluate the performance of the new material (L5) against controls (L0 and Vitapex).

Main Methods:

• Physicochemical testing according to ISO 6876 standards.
• Antibacterial efficacy evaluation.
• Comparison of injection and irrigation properties with Vitapex.

Main Results:

• The new material, L5, successfully met all ISO 6876 standards for root canal filling materials.
• L5 exhibited improved injection and irrigation handling compared to Vitapex.
• L5 demonstrated comparable antibacterial efficacy to the clinically used Vitapex.

Conclusions:

• The developed sodium iodide-based material (L5) shows potential as a new root canal filling option for primary teeth.
• Further verification of biological stability is recommended before clinical presentation.
• L5 could offer an improved alternative to existing materials, addressing concerns in pediatric endodontics.
