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
Pulpectomy is the treatment of choice for pulpally involved deciduous teeth, which potentially eliminates inflamed or necrotic pulp, bacteria, and toxins, relieving pain and promoting periradicular healing by cleaning and shaping the root canals. Over the years, cleaning and shaping of the root canals are done by manual endodontic instruments like files and reamers which are still considered to be the gold standard. With the advent and advances in Nickel Titanium rotary files, rotary endodontic instruments have been widely used for cleaning and shaping the root canals in Pediatric Dentistry. Of rotary files is less time-consuming thereby reducing stress to both the child and the dentist, giving consistent and predictable results even in narrow and curved root canals due to superelasticity and shape memory of nickel-titanium alloy.
