Effect of Two Desensitizing Agents in Reducing Dentin Hypersensitivity: An in-vivo Comparative Clinical Trial.

OBJECTIVE A randomized, double blind, split mouth, controlled clinical trial was conducted to evaluate the effect of two desensitizing agents on reduction of Dentin Hypersensitivity (DH). MATERIAL AND METHODOLOGY A sample of 73 teeth from 13 patients, among which at least 3 teeth had dentin hypersensitivity, was randomly allocated into 3 treatment groups: Group A: treated with 30% ethenolic extract of Indian Propolis, Group B: treated with GC tooth mousse, and Group C: treated with sterile water. A Verbal Rating Scale (VRS) was used to record the degree of hypersensitivity, based on patient's response to tactile and air blast stimuli. The baseline scores were obtained. Each intervention group received applications of their respective agents consecutively on 1(st), 7(th), 14(th) and 21(st) days. After each application, the scores were recorded. RESULTS Both the 30% Indian Propolis and GC tooth mousse showed significant reductions in dentin hypersensitivity. CONCLUSION GC tooth mousse was found to be significantly better in reducing the dentinal hypersensitivity as compared to Propolis and sterile water (p< 0.01).
