Sohail Rana noticed a trend in patients while studying at the University of Pittsburgh School of Dental Medicine. He saw that patients often selected the cheapest treatment options instead of best-quality treatments. “I didn’t feel that was fair for the individual who is really driven to maintain their oral health. I wanted to develop a way where we could catch problems much earlier and make people aware of the dangers of tooth decay,” said Rana, a fourth-year student in the school. Since he started seeing patients during his third year at Pitt, Rana and colleagues have been working on ways for people to practice better oral hygiene habits at home to avoid costly visits to the dentist’s office.
