title: Comparative evaluation of 2% sodium fluoride iontophoresis and other cavity liners beneath silver amalgam restorations.
abstract: BACKGROUND
  This study was designed to compare 2% sodium fluoride (NaF) iontophoresis with other cavity liners.
  
  
  METHODS
  This study was carried out in 30 patients in the age group 10-14 years with bilateral carious permanent first molars. The study evaluated the use of 2% NaF iontophoresis as a cavity liner and also compared its desensitizing effect with varnish and an adhesive bonded liner. Sensitivity gradings were done on a subjective verbal rating scale.
  
  
  RESULTS
  All the liner treatments decreased the sensitivity following liner application. However, decrease of sensitivity in the case of 2% NaF iontophoresis was more compared with that of varnish and adhesive bonded liner. The results were statistically significant.
  
  
  CONCLUSIONS
  It was found that 2% NaF iontophoresis was more effective in reducing the postoperative sensitivity compared with that of varnish and scotchbond multipurpose.
