Abstract
A periodontal survey applying CPITN was carried out in almost 500 male and female factory workers, 35-44 yr of age, in Shanghai, P.R. China. Calculus and shallow pockets were most frequent. Deep pockets of 6 mm and over were seldom found. The mean number of missing teeth was only 2.7 (out of 32). Problems associated with third molars seem to provide the largest immediate oral health problem.Entities:
