Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
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.
