Comparison of Dentin Hypersensitivity Reduction Over a 1-month Period

Not Applicable

Completed

• Conditions: Dentin Sensitivity
• Interventions: Other: Gluma; Other: fluoride varnish; Other: Tetric N-Bond self-etch adhesive

• Registration Number: NCT04351412
• Lead Sponsor: King Abdulaziz University

Brief Summary

Here we assessed the clinical effectiveness of Gluma, fluoride varnish, and the Tetric N-Bond one-step self-etch system in alleviating DH instantly and over 1 month, after a single topical application.A randomized, double-blind, clinical trial was conducted on 55 patients (25 males, 30 females; age: 20-49 years). Seventy teeth were randomly assigned to three groups: Gluma (n = 24); fluoride varnish (n = 23); and Tetric N-Bond adhesive (n = 23). Sensitivity to tactile, air blast, and cold stimuli were investigated.. A visual analogue scale was used to assess tactile stimuli, and the Schiff Cold Scale to assess air blast and cold stimuli. DH was evaluated immediately post-treatment, and at the 2-week and 1-month follow-up. Between-group and within-group comparisons were made.

Arm && Interventions

Group	Intervention	Description
Air blast stimulus	fluoride varnish	For air blast stimuli, air was delivered by a three-way syringe from a typical dental unit air syringe at 40 psi (± 10 psi) and 70 °F (± 5 °F). The air flow was aimed at the tooth surface of concern, for 1 second, from a distance of 1 cm. The air blast stimulus scores were assessed by the Schiff Cold Air Sensitivity Scale 18. DH was assessed for air blast stimuli at baseline and immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.
Tactile stimulus	Gluma	The tactile stimulus was examined using an explorer (# 17/23), passing at a right angle to the bucco-cervical tooth surface of concern. Contributors evaluated participants' pain score on a 10-point visual analogue scale (VAS). The stimulus was used to assess dentine hypersensitivity at baseline and immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.
Cold stimulus	Tetric N-Bond self-etch adhesive	For cold hypersensitivity assessment, the tooth was isolated using cotton rolls; then, a few drops of extremely cold water were delivered to the tooth from a syringe that had previously been cooled. The cold stimulus scores were assessed by the Schiff Cold Air Sensitivity Scale 18. DH was assessed for cold stimulus at baseline and immediately after completion of treatment. Subjects were also recalled for re-evaluation at 2 weeks and at 1 month after desensitizing treatment.

Primary Outcome Measures

Name	Time	Method
Assess dentine hypersensitivity score to stimuli immediately after treatment by intervention	From baseline to immediately after treatment with intervention	Scores of DH for tactile stimulus were recorded using visual analogue scale and for cold, and air blast stimuli using the Schiff Cold Air Sensitivity Scale 18 were recorded immediately after treatment with intervention and compared score to baseline.

Assess dentine hypersensitivity to stimuli at one month follow up after treatment by intervention	From baseline to one month follow up after treatment with intervention	Scores of DH for tactile stimulus were recorded using visual analogue scale and for cold, and air blast stimuli using the Schiff Cold Air Sensitivity Scale 18 were recorded at one month (30 days) follow up after treatment with intervention and compared score to baseline and immediate treatment, and two weeks follow up visit scores.
