title: Evaluation of the effect of enamel preparation on retention rate of fissure sealant.
abstract: BACKGROUND
  Prevention from caries is a principle in dentistry and fissure sealant therapy is being used as a preventive method success of sealants is directly depending on their retention.
  
  
  OBJECTIVE
  The Aim of the present study is to evaluate effects of enamel preparation on sealant retention.
  
  
  METHODS
  Clinical trial.
  
  
  METHODS
  About 57 children aged 6-8 year old took part in this study. 200 first molar teeth of these children has been randomly separated into two groups: A case group (Mechanically preparation of enamel) and a control group (conventional method, without preparation). After applying fissure sealants children were followed up 6 months later.
  
  
  METHODS
  Mann- U- Whitney Test was used.
  
  
  RESULTS
  Complete retention after 6 month follow up was 86.7% in case group and 82.8% in control group. No significant difference was seen between the groups after 6 month follow up. (P = 0.508).
  
  
  CONCLUSIONS
  Although statistical evaluation didn't show significant difference, but sealant retention was more after preparation technique.
