title: [A study on the state of periodontal health of 400 professional adults by random sampling in Shanghai].
abstract: OBJECTIVE
  To investigate and analyze the state of periodontal health of 400 adults at their post and risk factors in Shanghai.
  
  
  METHODS
  400 subjects (249 male, 151 female), aged from 25 to 59, were requested to fill a questionnaire. The probing depth (PD), clinical attachment level (CAL), tooth mobility (TM) and bleeding on probing(BOP) on 6 sites of each indicated tooth were measured and recorded. SAS 6.12 software package was used for statistical analysis.
  
  
  RESULTS
  OHI-S of Shanghai adults at their post was 2.16 +/- 0.99 and GI = 1.2227, indicating moderate gingivitis. The difference of periodontal disease among the adults at varied occupations in Shanghai municipality was significant. Periodontal destruction of the clerk group was the lightest The difference of periodontal disease among the adults at varied age groups in Shanghai municipality was also significant. Periodontal destruction of the elder group was heavier than of the lower age group. 146 subjects suffered from initial to moderate periodontitis. 140 subjects suffered from advanced periodontitis. 79, 317 and 4 subjects had received college education, high school education and postgraduate school education respectively. There was no relationship between the severity of periodontitis and educational level. 330 out of 400 (82.5%) subjects had never been treated, 70 out of 400 (12.5%) had scaling,and only 3.25% of subjects had received regular periodontal treatment.
