The CPITN Survey on Industrial Workers (II)

Application of the CPITN to Industrial Dental Health

Abstract

The purpose of this study was to examine the prevalence of periodontal disease in an industrial population, and to evaluate the effectiveness of introducing the CPITN into the industrial dental health. The CPITN survey was performed on 126 persons aged between 20 and 64 using the WHO periodontal examination probe.
Modified visible plaque index (VPI) examination and a conventional oral examination for periodontal disease were also carried out, and a questionaire about subjective periodontal symptoms was given to all subjects.
From the results of the CPITN code, subjects requiring periodontal treatment (TN-II) were over 92% in all age groups. The severity of periodontal disease increased with age. There were correlations between the CPITN and the VPI, and between the CPITN and subjective symptoms.
As a result, it is recognized that in this industry, nearly all subjects require treatment for periodontal disease, including dental health education. The CPITN is a simple and efficient method to evaluate the periodontal status in industrial workers.
