title: Risk group assessment of oral precancer attached to X-ray lung-screening examinations.
abstract: The mortality rate of oral tumours in Hungary, as in some other countries, is increasing. In order to assess risk groups for oral cancer and precancer, oral examinations were carried out as part of the X-ray screenings for lung cancer in the 3rd district of Budapest, Hungary. There were 5,034 adults who participated voluntarily in these investigations. After completing a questionnaire with 23 questions, a short oral examination was performed. Males comprised 57.7% of the group, and the age-distribution among men and women was similar. Oral precancerous lesions were found in 3.7% of the whole group, in 3.3% of those with leukoplakia, and in 0.4% of those with oral lichen planus. The prevalence of leukoplakia in men was 5.8%, and in women 1.5%, with significantly higher prevalences in men and women over 40. Among the examined persons there were 31% who were smokers, and 6% reported that they were regular consumers of alcohol. Fifty-four percent of those examined reported that they did not visit the dentist regularly. Oral complaints came mostly from those with lichen planus. The described model, where the oral screening examinations are done in conjunction with other examinations, in a so-called multiphasic screening system, seems to be a worthwhile approach for early diagnosis of oral cancer and precancer.
