Background: This study was designed to compare 2% sodium fluoride (NaF) iontophoresis with other cavity liners.Materials and Methods: This study was carried out in 30 patients in the age group 10-14 Refurbished Accessory 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 Home was found that 2% NaF iontophoresis was more effective in reducing the postoperative sensitivity compared with that of varnish and scotchbond multipurpose.
