The paper presents epidemiologic data of malignant oral tumors in Sweden 1958-77 including the total number of cases, the number and relative frequency of cases in different sublocations of the oral region and the mean annual age standardized incidence rate, all ages, per one million population, by site and sex. An analysis of different histopathologic types of oral tumors is also presented. A comparison is made between the two 10-yr periods 1958-67 and 1968-77. Errors involved in epidemiologic studies are discussed.
