As a qualitative addition to her research trajectory and a reinforcement of her presence on the international scientific landscape, Lecturer Dr. Ithmar Ali Kadhim, a faculty member at the College of Health and Medical Technologies / Kufa, one of the formations of Al-Furat Al-Awsat Technical University, contributed—within a specialized international research team—to the publication of a distinguished scientific paper entitled:
“Organosilica nanoparticle-reinforced resin-based dental composites: synthesis, characterisation, and evaluation of physicochemical properties,”
published in RSC Advances, a journal of the Royal Society of Chemistry (UK), classified ضمن الربع الأول عالميًا (Q1) according to Scimago (SJR) rankings, with a CiteScore of 7.6, SJR of 0.777, and SNIP of 0.964, placing it among the top-tier scientific journals worldwide.
The research team included a group of scholars from the Colleges of Dentistry, Pharmacy, and Engineering at the University of Babylon, in coordination with research centers in Hungary.
The study focused on providing fundamental solutions to the technical challenges associated with conventional composite materials in dentistry. The team successfully developed advanced hybrid nanoparticles based on a core–shell structure, consisting of a solid silica core surrounded by a porous organosilica shell.
Laboratory results substantiated the feasibility of this innovation, as the team succeeded in transforming the filling material from hydrophilic to hydrophobic, resulting in a 75% reduction in oral fluid absorption. Moreover, polymerization shrinkage was significantly reduced by up to 78.5%.
Collectively, these indicators contribute to the production of dental restorations with enhanced resistance to fracture and chemical degradation, thereby substantially reducing the likelihood of long-term failure of dental fillings and opening promising prospects for the development of next-generation restorative dental materials.
