title: Can a workplace preventive programme affect periodontal health?
abstract: OBJECTIVE
  To evaluate an oral health awareness campaign in an adult population.
  
  
  METHODS
  Four workplaces in north-east London were selected, matched in two pairs and randomly allocated to test and control groups. Completion occurred in 1995.
  
  
  METHODS
  98 volunteer employees in good general health.
  
  
  METHODS
  Two oral examinations were carried out, six weeks apart. The test group received the programme immediately after baseline examination and the controls after the second visit.
  
  
  METHODS
  Gingival bleeding on probing (BOP) and probing depths (PD) were measured on each occasion using a controlled pressure probe.
  
  
  RESULTS
  The mean percentage of sites with BOP per subject reduced from 56% to 25% in the test group, while remaining static in the control group at 46% to 48%. The mean percentage of sites probing 4 mm and above per subject reduced from 38% to 25% in the test group and from 28% to 25% in the control group. These differences between groups were statistically significant when submitted to analysis of covariance (P < 0.001).
  
  
  CONCLUSIONS
  The study showed the clinical effectiveness of a workplace-based oral health awareness campaign, which is ideally suited to the skills and resources of the primary care dental team.
