Abstract

The incidence of dental problems is increasing owing to the modern lifestyle, sticky food and poor dental hygiene. Root canal treatment is one of the most common clinical practices in conservative dentistry. Despite the availability of various GIC materials, strength and durability remain the most common concerns. The mechanical properties of tooth filling material are compromised due to disturbances in glass and liquid composition or powder/liquid ratio, glass particle size, pretreatment, manual mixing. The intrinsic porosity is also influenced by reduced viscosity or compared with proportionate liquid ratio, resulting in increased porosity in the cement structure. The availability of nanoparticles, specifically that of perovskites, opens a new dimension. Since they are relatively smaller in size, they can offer stronger binding and cementing properties.
