Amman, Jordan — August 24, 2025. The University of Jordan's “BioMed Materials" research group, represented by Dr. Yazan Al-Zain, held a two-hour meeting with Assoc. Prof. Dr. Taher Mohammed Nabil Al-Omari (Department of Conservative Dentistry, Jordan University of Science and Technology) and his master's student Dr. Mohammad Rahhal to explore joint research opportunities in endodontic file instrumentation and biomaterials.

Dr. Al-Omari is a clinician–scientist in restorative dentistry and endodontics whose recent work examines rotary and reciprocating root-canal file systems, debris extrusion, cyclic fatigue, and irrigation parameters—topics tightly linked to file performance and patient outcomes. Recent examples include studies on reciprocating angles and debris extrusion as well as irrigation solution temperature and heat application effects on treatment efficacy.

During the meeting, both teams mapped out synergy between clinical endodontic needs and materials-science solutions from UJ's BioMed Materials group, whose mission centers on designing and characterizing advanced biomaterials (e.g., titanium-based and high-entropy alloys, and 3D-printed polymers) for durable, biocompatible materials and devices. Potential collaboration tracks include:

• Alloy & heat-treatment optimization for NiTi-class or alternative file materials to improve fatigue and torsional resistance.
• Surface engineering & coatings to reduce debris extrusion and enhance cutting efficiency.
• Corrosion, wear, fatigue strength, bending stiffness, and sterilization durability studies under clinically relevant irrigation chemistries and temperatures.
• Additive manufacturing & micro-texturing to tune flexibility and cutting behavior in next-gen file prototypes.
• In-vitro electrochemical and cytocompatibility testing leveraging BioMed Materials' established workflows.

Dr. Al-Omari's profile and publication list on JUST's official portal and ResearchGate highlight sustained contributions to endodontic practice and dental materials—reinforcing the fit for a translational partnership bridging chairside performance with materials-level innovation.

Next steps agreed in principle:

1. Define shared research questions (debris extrusion vs. angle/kinematics; fatigue life under thermal/irrigation cycles).
2. Develop a materials–testing matrix (alloy/heat-treat/surface vs. cyclic fatigue, torsion, corrosion, sterilization).
3. Initiate a pilot study co-supervised by both teams, with joint authorship targets and clinical translation pathways.
