title: Oral piercings among first-year university students.
abstract: OBJECTIVE
  The aim of the study was to examine oral piercings among first-year university students.
  
  
  METHODS
  First-year university students in 2002 were invited to a dental examination (n = 234; 49 men and 185 women). Students with piercings formed the study group and the rest served as controls. The methods included decayed, missing, and filled teeth (DMF) index, stimulated salivary flow rates, panoramic tomograms, and questionnaires including the Depression Inventory of Beck. Fisher's 2-sided exact test was used for statistical analysis.
  
  
  RESULTS
  The prevalence of oral piercings was 3.4%. In the DMF indices, no statistically significant differences existed between the groups. Increased salivary flow rates were noted among students with piercings (63% vs 26%, P < .05). Use of tobacco and illicit drugs, and also depression, were more prevalent in the study group than in the controls.
  
  
  CONCLUSIONS
  Because of the possibility of oral implications, follow-up of oral piercings is essential.
