Nanotechnology and Dental

Jamia Millia Islamia is planning to set up its own dental college from the next academic session. As per the Dental Council of India (DCI), if any varsity wants to open a dental college, it must sign an MoU with a government hospital within a 10-km radius, or have a 100-bedded hospital facility of its own.
Course coordinator of the Faculty of Dentistry Professor Arif Ali said the university is signing an MOU with ESI Hospital, which is located three kilometres away. The CPWD has assured that by August, 42,000 square metres will be ready for the college. The university will be ready for the DCI inspection . The college, which is being designed by renowned architect, Romi Khosla, will be built by the CPWD on an area of 1.25 lac sq metres.
The six winged six floor buildings, which will be built at an estimated cost of Rs 45 crore, will be equipped with at least 24 dental chairs imported from Brazil. Once operational, the college will offer a four-year Bachelors in Dental Sciences with an intake of 50 students.

An Application of Nanotechnology in Advanced Dental Materials :-

Researchers have investigated the potential for nanotechnology to improve the durability of dental fillings. Dental fillings are used to repair the damage caused by tooth decay. The decayed portion of the tooth is removed and the remaining hole is filled with the restoration material. However, these fillings do not last a lifetime. They may crack or loosen, and additional decay may develop in the surround tooth. Among the most common restorative materials is composite resin. Composite resin is composed of glass or quartz fillers and an acrylic plastic material. A decay-fighting additive is included in many composites. The additive releases a steady supply of calcium and phosphate ions, which strengthen the surrounding tooth and help prevent further decay. However, these additives are structurally weak, and their addition to the composite mix weakens the filling as a whole. Some Researchers developed new forms of the decay-fighting additive that are 20 times smaller than the additive currently in use. Due to their smaller size, far fewer of these nanoparticles are required than their predecessors for the same effect. This allows more room for the stronger materials in the composites, resulting in a composite material that is stronger, overall. According to the Paffenbarger scientists, these newly developed nanocomposites may be nearly twice as strong as the variety currently available to dentists.
