Undergraduate student research in dental biomaterials is pivotal for advancing the field. Rasha Rahhal and Leen Hmood, are now working on research project related to the longeivty of CAD/CAM materials. This research aligns with current trends emphasizing the need for materials that combine excellent mechanical properties with biological functionality, ultimately aiming to improve patient outcomes in dentistry.
Dr. Abdulaziz Alhotan, in collaboration with dental interns from the College of Dentistry at King Saud University, published a research paper in the Journal of Prosthetic Dentistry titled:
“Effect of Simulated Gastric Acid Exposure on the Hardness, Topographic, and Colorimetric Properties of Machinable and Pressable Zirconia-Reinforced Lithium Silicate Glass-Ceramics”
This study examines the impact of simulated gastric acid exposure on the mechanical and aesthetic properties of zirconia-reinforced lithium silicate (ZLS) glass-ceramics, which are commonly used in dental restorations. It highlights changes in hardness, surface topography, and colorimetric stability, providing insights into the durability and performance of ZLS materials in acidic environments.
Co-supervisor for Rana Khair at the University of Khartoum, I am guiding her master’s thesis titled “The Effect of Different Cleaning Solutions on the Color Stability and Surface Roughness of Polyamide Denture Base Material.” This research investigates how various cleaning agents influence the aesthetic and mechanical properties of polyamide denture bases, which are crucial for patient satisfaction and longevity of dental prosthetics. By conducting rigorous testing, Rana aims to provide valuable insights that could lead to improved practices in denture maintenance and material selection in clinical dentistry.
Dr. Julfikar Haider supervised Ahmed Altarazi’s PhD research at the University of Manchester, focusing on the development of 3D-printed denture base resins reinforced with nanoparticles. Their collaborative work has significantly advanced dental materials science, particularly in improving the mechanical, biological, and antifungal properties of these materials.
