LINCOLN, Neb. (AP) — The University of Nebraska Medical Center’s College of Dentistry museum in Lincoln will open for public tours later this month.

The museum holds the largest public display of dental artifacts dating back to the 1850s.

Stan Harn, professor of oral biology and curator of the museum, says the museum has added a huge number of new items this year. The display will include six period dentist offices from the 1850s to the 1930s, several dental chairs dating from 1840 to 1880, and a collection of tooth extraction instruments dating from the 16th century.

The public tours will be held daily from Sept. 22 through Sept. 27. Free parking is available on the east side of the building in the patient parking lot.
