UM, Fla. firm develop Bioglass toothpaste

Maryland Watch

September 11, 1997

University of Maryland School of Dentistry researchers said yesterday that a toothpaste they've developed with a Florida biotechnology company has been shown in a study to provide lasting relief for a painful condition known as hypersensitive teeth.

The gel toothpaste was co-developed by USBiomaterials Corp., a former White Marsh-based company now in Florida. The toothpaste contains Bioglass, which contains a glass compound that bonds to human bone and tissue.

USBiomaterials said it anticipates that a Bioglass toothpaste will be on the market in the United States within two years. The privately held company said it is in marketing discussions with several companies.

In the study, a group that used a toothpaste containing high concentrations of Bioglass showed a statistically significant decrease in tooth sensitivity, according to Dr. Leonard Litkowski, associate professor and director of bioactive materials and devices research at the University of Maryland dental school.

The study also evaluated people who used a toothpaste with lower concentrations of Bioglass.
