Abstract
A periodontal screening and recording (PSR) system was used to examine the periodontal disease state in a mass oral examination. The results of the PSR were compared with those from a selfevaluation by questionnaire survey. The patients were 100 newly-enrolled participants in dental screening at a certain factory (74 males and 26 females: average age, 49.1 years). The oral cavity was divided into six regions for the PSR evaluation, and the results of the PSR were classified into 5 codes. Plaque adhesion was examined for plaque control record (PCR) evaluation. Questionnaire survey items included : identification of periodontal disease, understanding of periodontal disease, brushing method, brushing frequency, brushing time, and the presence or absence of scaling. A statistical relationship between the PSR codes and both the PCR points and the questions was examined by the x2 test and F-test. Code 3 was the most common in PSR evaluation in this study. The PCR scores of Code 3 and Code 4 were higher than Code 1 (p< 0.05). The results of the identification of periodontal disease were at a higher ratio following the Code (p <0.01, p< 0.05). These results indicate that PSR can serve as a screening, evaluating and recording tool for periodontal disease and will be useful for the early detection, early treatment, and management of periodontal diseases, especially when supplemented with self-evaluation by questionnaire survey.
