Fluoride Silicon-Toothpaste Associated With Calcium Booster for Dentin Hypersensitivity Treatment

Objectives: Dentin hypersensitivity affects a significant portion of the world's population, causing pain and negatively impacting oral health and quality of life. This clinical study investigated the effectiveness of a desensitizing fluoride silicon-rich dental gel associated with a calcium booster.
Methods: In this single-blind, randomized, parallel-group clinical trial, forty-eight volunteers diagnosed with dentin hypersensitivity and qualified to participate were randomized into 2 groups: (1) fluoride silicon-rich dental gel (REFX Technology)/calcium booster (Si/Ca protocol); (2) Pumice stone diluted in saline. A draw was carried out between the right and left sides of the patients so that either a prophylaxis with the dental gel associated with calcium or with fine pumice stone diluted in saline was carried out. An evaporative test was used to check for dentin hypersensitivity in the subjects before and immediately after treatment and scored using the Schiff scale, rated 0 to 3. Data were statistically analyzed (ANOVA/Tukey test, α=5%).
Results: The average age of the subjects in this clinical study was 46 years, and 53.84% of the 48 participants were female. The treatment with Si/Ca protocol drastically reduced dentin hypersensitivity (from 2.58 to 0.67) immediately after the use. In the control group (Pumice stone), similar results were observed before and after treatment (2.67 and 2.82, respectively). Immediately after the application of the Si/Ca protocol, the evaporative analysis indicated that 24.4% of the teeth obtained complete remission of sensitivity (score 0). Additionally, 40.0% experienced a higher decrease in sensitivity levels (around 70%), and 35.6% experienced one third of pain relief. Conversely, when the teeth were treated with pumice stone diluted in saline, 84.4% of the subjects reported no pain relief, whereas 15.6% reported pain augmentation by one third.
Conclusions: The Si/Ca protocol was fast and effective in reducing pain caused by dentin hypersensitivity.
