Introduction: Dentin Hypersensitivity (DH) is known to be a relatively common condition that affects a considerable portion of the population, and manifests itself in the form of acute pain, due to the exposure of dentin and open dentinal tubules, after the removal of enamel or root cement. It has a multifactorial aetiology.
Aim: To compare the efficacy in DH treatment using Biosilicate and Gluma Desensitiser.
Materials and Methods: This randomised clinical trial pilot study with a split-mouth design included seven participants. Two teeth presenting Gingival Recession (GR)-related DH were selected in each participant and allocated to treatment groups by simple randomisation. Gluma® desensitiser (GD) and Biosilicate® (BIO) were applied once a week for four weeks. The pain intensity under a volatile stimulus was measured using a Visual Analogue Scale (VAS) at baseline and after treatment, at 15 days and 6 months follow-up. Data analysis were performed by means of descriptive statistics, Paired t-test for inter-group comparison and Friedman test for intra-group comparison (p-value <0.05).
Results: The mean age of seven participants were 19.9 years, from which five were women (71.4%). The GD and BIO groups presented initial mean VAS values of 4.86±2.55 and 6.14±1.57, respectively. Fifteen days after treatment, both groups showed a significant improvement (GD group p-value=0.03 and BIO group p-value=0.02, Wilcoxon test) in pain intensity, with 71.4% teeth without sensitivity (VAS=0).
Conclusion: Both treatments resulted in a reduction in painful sensitivity under volatile stimuli 15 days after treatment. BIO group presented a better outcome regarding reduction in DH, without recurrence at the 6th month evaluation, when compared to GD group.
