title: Oral roentgenologic findings in a Norwegian urban population.
abstract: Orthopantomograms were taken of 111 subjects constituting a random sample of 35-year-old citizens of Oslo. The most frequent pathologic finding was marginal bone loss, which was found in seventy-one persons (64%). Fifty-one impacted and unerupted teeth in twenty-eight persons were seen, the third molars predominating. Ten retained roots were found in nine persons, and apical radiolucent areas were found on forty-four teeth in thirty-three persons. In addition to the pathologic findings, 101 endodontically treated teeth in fifty-five persons were observed.
