Prevalence study of oral leukoplakia in a selected population of 1000 patients from the Netherlands

Abstract

A survey of a special population, the outpatients of a Department of Oral Surgery of a Teaching Hospital in Amsterdam, revealed a comparatively low prevalence rate for oral leukoplakia of 14/1000 patients (1.4%). No difference was found in the age distributioncompared with similar investigations elsewhere in the world. However, in contrast with previous findings, which show a significant difference between prevalences of leukoplakia for men and women, leukoplakia was equally distributed between both sexes.
