Background: Dentinal hypersensitivity is one of the most common painful conditions to visit dental clinic. Identification of the etiological factor and management of the same is of prime concern. Till date no universally accepted treatment modality is available. Thus the aim of the present study is to evaluate and compare the efficiency of sodium fluoride varnish, dentin bonding agent and acidulated phosphate fluoride (APF) gel iontophoresis in treating dentinal hypersensitivity.
Materials and Methods: Eighteen individuals with 92 teeth diagnosed with hypersensitivity were selected. Patients with VAS score of ≥5 on application of tactile or air-blast stimuli were included. The desensitizing agents used were Sodium fluoride varnish, dentin bonding agent and APF gel Iontophoresis. The teeth were evaluated immediately after treatment and at 1, 2 and 4 week recall interval.
Results: The results were statistically analyzed using Repeated measures ANOVA and One way ANOVA test. There was a significant decrease in the mean VAS scores from baseline to 4 week in all groups.
Conclusions: All three agents showed statistically significant reduction in sensitivity compared with baseline. However, APF gel iontophoresis showed immediate as well as sustained desensitizing effect at all time intervals with lesser need of retreatment.
