Examination of the reaction kinetics and internal porosity of 8 resin based composites placed in a patient simulator
This project will improve how tooth-coloured fillings are placed and hardened in everyday dentistry. Using advanced infrared spectroscopy, the team will track how eight modern filling materials react when cured with powerful blue light, showing when the reaction starts, how quickly it proceeds, and how completely each material hardens. High-resolution micro-computed tomography (micro-CT) will also be used to examine fillings placed in artificial teeth to detect tiny internal air bubbles or gaps in the fillings that cannot be seen on standard X-rays. By comparing 8 different materials and placement techniques, the study will identify combinations that harden well and contain fewer voids, helping fillings last longer, reduce emergency visits, and lower dental costs for Canadians.
