About this study

Official title: Clinical Evaluation of Different Potassium Oxalate Concentrations in Dentin: A Randomized Clinical Trial

This study aims to evaluate the longevity and efficacy of two products potassium oxalate-basedin two concentrations, 10% and 5%, by triple randomized blind clinical trial (split-mouth) . The desensitization approach (single agent) and the long-term effectiveness (baseline, 1 week, 2 weeks, 3 weeks). Data will be collected, tabulated and submitted to statistical analysis.

Read the detailed description

Dentin hypersensitivity (DH) is characterized as a short, intense and sudden pain caused by thermal, chemical and evaporative stimuli. There are several types of desensitizing agents, used to aid in the control of this pathology, but they are not very effective and have short longevity. The agents based on potassium oxalate have been used by dental surgeons because they have mixed action, both neural and obliterating. Therefore, the aim of this study is through a triple blind randomized clinical trial (split-mouth), evaluate the longevity and efficacy of two products potassium oxalate-based in two concentrations, 10% and 5%. Thirty-two with DH at least 2 teeth and adequate oral hygiene will be randomly divided into two different groups according to the desensitization approach (10% and 5%) The dentin hypersensitivity level will be evaluated immediately after desensitization and after 1, 2 and 3. Data will be collected, tabulated and submitted to statistical analysis.

Questions about this trial

What is this clinical trial studying?

A study testing Potassium Oxalate 5% and Potassium Oxalate 10% in people with Dentin Sensitivity and Hypersensitivity Dentin, run by Federal University of Uberlandia at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

What does the primary outcome measure?

Level of cervical dentin hypersensitivity by using visual analog scale (time frame: 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03083496, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
