Effect of two desensitizing agents on dentin hypersensitivity: A randomized split-mouth clinical trial

Area of Science:

• Dentistry
• Dental Materials Science

Background:

• Dentin hypersensitivity is a common clinical condition.
• Effective desensitizing agents are crucial for patient comfort and oral health.
• Evaluating novel agents like Uno Topical Gel and Profluorid Varnish is essential.

Purpose of the Study:

• To compare the immediate and one-week desensitizing efficacy of Uno Topical Gel versus Profluorid Varnish.
• To assess the dentin tubule occlusion potential of both agents using scanning electron microscopy (SEM).

Main Methods:

• A randomized clinical trial involving 35 patients with dentin hypersensitivity.
• Application of Uno Topical Gel or Profluorid Varnish to quadrants, with sensitivity assessed via Visual Analog Scale (VAS).
• SEM analysis of dentin discs treated with agents to evaluate tubule occlusion at 1 and 24 hours.

Main Results:

• Uno Topical Gel showed significantly better immediate relief from evaporative stimuli (P=0.01).
• After one week, Uno Topical Gel demonstrated superior efficacy for both tactile (P=0.000) and evaporative (P=0.000) stimuli.
• SEM revealed over 90% tubule occlusion by Uno and 80% by Profluorid at 1 hour; occlusion decreased to over 50% and 60% respectively at 24 hours.

Conclusions:

• Uno Topical Gel is significantly more effective than Profluorid Varnish in alleviating dentin hypersensitivity pain.
• The findings support Uno Topical Gel as a preferred treatment option for dentin hypersensitivity.
• Both agents showed tubule occlusion, but Uno demonstrated more sustained effectiveness.
