Penn Dental Medicine to receive $20M estate gift honoring alumnus

One hundred and four years after Penn Dental Medicine alumnus Dr. Arthur E. Corby, Class of 1917, earned his dental degree, his daughter, alumna Carol Corby-Waller, has gifted the Dental School with an anticipated $20 million honoring her father.
A gentler strategy for avoiding childhood dental decay

An enzymatic treatment significantly weakened a bacteria-yeast biofilm on a tooth-like surface. This therapeutic approach, using beta-mannanase (right panel) breaks down the links between the bacteria and yeast, could be used to treat early childhood caries, a severe form of tooth decay.

A gentler strategy for avoiding childhood dental decay

By targeting the bonds between bacteria and yeast that can form a sticky dental plaque, a new therapeutic strategy could help wash away the build-up while sparing oral tissues, according to a new study by a team from the School of Dental Medicine.
