title: Effectiveness of two different desensitizing varnishes in reducing tooth sensitivity: a randomized double-blind clinical trial.
abstract: OBJECTIVE
  The aim of this study is to evaluate and compare the effectiveness of two different desensitizing varnishes.
  
  
  METHODS
  Ninety healthy adults suffering from tooth sensitivity were divided into three groups. Two different varnishes were used for the study: Fluor Protector S, containing 7700 ppm fluoride (group I), and Cervitec F, containing 1400 ppm fluoride and 0.3% chlorhexidine (group II). A placebo containing water and ethanol was applied for the third group. Tooth sensitivity was collected according the Schiff' scale at baseline and after 30 and 90 days.
  
  
  RESULTS
  Group I and group II improved with statistically significant results. Group III did not show any improvements.
  
  
  CONCLUSIONS
  Desensitizing varnishes are a valid treatment for tooth hypersensitivity.
