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

Abstract

Objective: A randomized, double blind, split mouth, controlled clinical trial was conducted to evaluate the effect of two desen sitizing 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).

Prevalence of dentinal hypersensitivity and study of associated factors: a cross-sectional study based on the general dental population of Davangere, Karnataka, India

“…reported mean VRS scores of 1.7 ± 0.9 and 1.5 ± 0.8 in the placebo group with AS and TS, respectively. Torwane et al . reported 16% of teeth with mild pain and 56% with moderate pain after AS in their Group A (treated with 30% ethenolic extract of Indian Propolis), whereas in the same group 32% of teeth had mild pain and 36% had moderate pain after TS; the authors stated that moderate DH was more prevalent than severe or mild DH.…”

Comparative evaluation of the effectiveness of desensitizing agents in dentine tubule occlusion using scanning electron microscopy

“…and Sales‐Peres et al . Propolis has also recently been proven to be clinically effective in reducing DH . This may be attributed to the interaction between the high content of flavonoids in RPE and the dentine, forming crystals that are able to adhere to the dentine surface and occlude the dentinal tubules .…”

“…RP has been reported to have a high concentration of phenolic acids and flavonoids which have been associated with a variety of health benefits . Propolis has been used in the treatment of DH and found to be effective . However, no study has compared the effect of red propolis extract (RPE) with other desensitizing agents in relieving DH.…”

Effect of Low-Level Laser Therapy in Reducing Dentinal Hypersensitivity and Pain Following Periodontal Flap Surgery

“…Air blast (thermo evaporative stimuli) with an air syringe at a distance of 1 cm from the site was used on test and control sites for 1-2 sec for assessing DH. 26 …”
