The blue curing light used to harden dental fillings may stunt tumour growth as well, a team of researchers that included an Indian origin scientist has found. The findings are based on a study of 10 tumour-bearing mice, five treated with the light and five untreated.

An international team of researchers have come up with a novel technique that may offer a treatment option for dental caries or tooth decay. Dental caries, or tooth decay, continues to be the most prevalent infectious disease in the world, which leads to the loss of the hard tissues of the tooth, followed by inflammation and necrosis (cell death in living tissues) of the subjacent dental pulp.
