Abstract
Objectives: The aim of this study was to evaluate appropriate timing of topical fluoride application using iontophoresis in case of composite resin restoration for non-carious cervical lesions.
Methods: Eighty teeth were sound premolars extracted for the orthodontic treatment and randomly assigned to 4 groups. According to the timing of topical fluoride application (TPA), groups divided into 1) 1 st group (control group): ordinary composite resin filling, 2) 2nd group: TPA before acid etching, 3) 3rd group: TPA after acid etching, 4) 4th group: TPA after composite resin filling. The effect of topical fluoride application on retention of restorations was tested by shear bond strength.
Results: Average shear bond strength was 39.84 N/mm2 in control group, 40.52 N/mm2 in 2nd group, 36.71N/mm2 in 3rd group and 40.39 N/mm2 in 4th group. One-way Analysis of Variance (ANOVA) testing revealed that there was no statistically significant difference in all groups (JJ ) 0.05).
Conclusions: It would be better to apply topical fluoride using iontophoresis before composite resin filling for non-carious cervical lesions. It will help to reduce the dentinal hypersensitivity of patients and practitioners could expect better results of restorations.
