NCT03851900

Brief Summary

This randomized, controlled, clinical trial aimed to compare the 6- month clinical performance of a desensitizer that contains calcium phosphate TM with a two-step self-etch adhesive SE and placebo (distilled water). At least 150 teeth wil be treated with desensitizing products and placebo randomly one third usig TM, one third using SE and one third using placebo. The efficiency of the materials will be evaluated at baseline, 1 week, 1 month, 3 months and 6 months after treatment.

Outcome Measures

Primary Outcomes (1)

  • The effectiveness of desensitizers through long-term period

    The clinical efficacy of a desensitizer that contains calcium phosphate with a two-step self-etch adhesive and placebo through a long-term period. Evaluation will be performed usig the Visual Analog Scale(VAS). VAS values will be according to the following parameters: 0 - no discomfort;1 to 3 - light discomfort;4 to 6 - mild discomfort;7 to 9 - severe discomfort;10 - Unbearable discomfort. After each stimulus to the suspected site the degree of hypersensitivity will be determined from 6 to 10 as the preop VAS score for each individual painful tooth.

    6 months

Secondary Outcomes (1)

  • Subjective satisfaction of patients

    6 months

Study Arms (3)

Teethmate Desensitizer (TM)

EXPERIMENTAL

Calcium phosphate biomimetic material that forms hydroxyapatite from tetracalcium phosphate and dicalcium phosphate anhydrous and plug the dentin tubules causing remineralization and dentin hypersensitivity relief.

Other: Teethmate Desensitizer (TM)

Clearfil SE Bond 2 (SE)

ACTIVE COMPARATOR

Two-step self etch adhesive resin treating dentin hypersensitivity b covering a film layer after light-curing.

Other: Clearfil SE Bond 2

Distilled water

PLACEBO COMPARATOR

Distilled water with no desensitizing components.

Other: Distilled water

Interventions

Desensitizing agent will be applied to sensitive teeth.

Teethmate Desensitizer (TM)

Desensitizing agent will be applied to sensitive teeth.

Clearfil SE Bond 2 (SE)

Placebo will be applied to sensitive teeth as a negative control.

Distilled water
