Indian Institute of Technology, Madras (IIT-M), researchers have developed a new pain-free, long-lasting formulation of dental filling that does not shrink.

Dental restorationMadha Dental College and Hospital professor and head, department of conservative dentistry and endodontics, Dr V Susila Anand said conventional dental composites shrink by up to 5% which not only leads to postoperative sensitivity or pain, but also causes gaps between the teeth and fillings.

The composition of the new filling contains unique organic resins and inorganic fillers that will not affect the endocrine system, Anand said. She also stated that the research had a three-speared approach – to reduce the sensitivity post the filling, prevent shrinkage and improve biological safety for patients.

Venkatesh Balasubramanian, department of engineering design professor at IIT-M, said the new chemical formulation was put through rigorous chemical tests to check its stability.
