The activity report of the oral cancer screening in tokyo dental college

—Mass screening of the oral cancer screening in all area and individual screening in Chiba-city—

Abstract

Recently, the incidence of oral cancer in Japan has been increasing. Tokyo Dental College started oral cancer screening in cooperation with a local dental association in 1992. Here, we report the actual results of mass screening and individual screening for oral cancer.
Mass screening for the public was performed in each region. Individual screening was performed in a general dental clinic of a cooperating physician. In mass screening, we checked 18,590 subjects from 1992 to 2017; the ratio of males to females was 1：3 and the oral cancer detection rate was 0.13％. In individual screening in Chiba city, we checked 4,369 subjects from 2006 to 2017; the ratio of males to females was 1：2.1 and the oral cancer detection rate was 0.14％. We also detected many potentially malignant oral disorders.
We are now developing an oral cavity cancer navigation system and fluorescence optical equipment, and are planning to perform further activities for the early detection and treatment of oral cancer.
