Abstract
The purpose of this study was to examine the availability of the CPITN and the B.I. (Bleeding Index) for adults in the dental health administration system of preventive dental clinics. At the outpatient clinic in the hospital of Nagasaki University School of Dentistry, we have managed to control periodontal disease using a maintenance dental care system consisting of oral examination, motivation, tooth brushing instruction, scaling, and periodic recall based on an original screening method.
We analyzed the data obtained over a 2-year period from 472 patients (aged 15 to 70, who were new cases from April, 1984 to September, 1986). As the result of continuous administration of this dental care system, the B.I. decreased to about half the value of the first examination. In addition, we could easily estimate the manpower necessary to provide preventive treatment of periodontal disease to the public. If a dental team composed of one general dentist and two dental hygienists works 6 hours a day, 5 days a week, they can offer this program to 1, 167 people, excluding serious patients with CPITN code 4.
We concluded that the application of CPITN with B.I. was useful in the screening of patients, the evaluation of prognosis at each recall examination, and the estimation of manpower.
