Comparison of two treatment modalities for treatment of dentinal hypersensitivity following periodontal therapy.

Abstract

Brief Background To evaluate and compare efficacy of 1.23% Acidulated Phosphate Fluoride (APF) gel with iontophoresis and topically applied calcium sodium phosphosillicate in the treatment of dentinal hypersensitivity. Materials and Methods In this clinical study, a total of 72 participants with dentinal hypersensitivity (DH) after periodontal treatment were included. 36 participants were assigned to the test group, treated with 1.23% APF gel iontophoresis and 36 participants were in the control group, treated with topical application of calcium sodium phosphosillicate. The VAS score was measured using tactile, air blast and cold-water test at baseline, 2 weeks and 2 months. Results Inter group comparison showed, statistically significant reduction in difference from baseline to 2 weeks follow-up and baseline to 2 months follow-up in VAS score in test group as compared to control group (p<0.001) except for difference from baseline to 2 weeks in air blast test where test and control group showed same reduction. Difference from 2 weeks to 2 months showed no statistically significant reduction in both groups. Intra group comparison showed, statistically significant reduction in baseline to 2 weeks and baseline to 2 months in both groups and from 2 weeks to 2 months no statistically significant reduction in VAS score in both groups. Summary and Conclusions Within the limitation of the study, it can be concluded that iontophoresis with 1.23% APF gel is more effective.
