Abstract
A dental examination, including posterior bite-wing radiographs, was conducted of freshman resident nonveteran students at Oregon State College. The study showed: (1) The DMF teeth rates are considerably higher than in students of the same age groups in other parts of the country. The avg. DMF teeth for the 17-yr.-old freshman was 12.2, while for students of the same age in Hagerstown, Md., San Francisco and New York City it is approx. 8 DMF teeth. (2) Female students have a higher DMF rate than males and also have received better dental care. (3) Freshman students have fewer missing teeth and fewer teeth requiring extraction than students of other parts of the U. S. (4) The value of bite-wing radiographs as a diagnostic tool was demonstrated. (5) Two geographic areas within the State differ in incidence of dental decay.
