Five-Year Study Confirms High-Viscosity Glass Ionomers Deliver Reliable, Composite-Level Results in Small Class II Restorations
A five-year randomised clinical trial has assessed the performance of high-viscosity glass ionomer restorative systems in small Class II restorations, providing valuable evidence for everyday dental practice.
Conducted by Dr. Ramy Ahmed Wafaie, Dr. Ashraf Ibrahim Ali, Dr. Salwa Abd El-Raof El-Negoly, and Dr. Salah Hasab Mahmoud, the study evaluated the durability, fluoride release, and overall clinical reliability of these materials compared with traditional composite restorations.
The trial demonstrates that modern high-viscosity glass ionomers, including Riva, deliver outcomes comparable to composites while offering additional benefits such as fluoride release and chemical bonding to tooth structure. These findings reinforce the role of glass ionomers as a practical, bioactive, and minimally invasive solution, particularly for patients where moisture control is challenging or rapid placement is needed. The study provides dentists with evidence-based guidance to confidently incorporate high-viscosity glass ionomers into routine restorative procedures.
