About this study

Official title: Analysis of the Association of Products for the Treatment of Cervical Dentin Hypersensitivity

The aim of this study is through a randomized clinical trial, double blind, splith-mouth, evaluate the various types of protocols and clinical efficacy in the reduction or even elimination of dentinal hypersensitivity by the agents Desensibilize KF - FGM Dental Products, Clinpro - 3M Company, Minnesota - USA, Photon Laser III - DMC, Brazil, Desensibilize KF and laser, Desensibilize KF and Clinpro, laser and Clinpro and the association of all products.

Read the detailed description

Cervical dentin hypersensitivity is a painful condition and is a clinical challenge due to different treatment strategies available. The aim of this study is through a randomized clinical trial, double blind, splith-mouth, evaluate the various types of protocols and clinical efficacy in the reduction or even elimination of dentinal hypersensitivity. A hundred forty teeth of healthy patients of both sexes were selected. Visual Analog Scale was used pain (VAS) to measure the intensity of the patient's pain. The teeth will be randomly divided into 7 different groups according to the desensitization treatment under study: Desensibilize KF - FGM Dental Products, Clinpro - 3M Company, Minnesota - USA, Photon Laser III - DMC, Brazil, Desensibilize KF and laser, Desensibilize KF and Clinpro, laser and Clinpro and the association of all products. Data will be collected, tabulated and submitted to statistical analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Resin modified glass ionomerDrug

    Also called Clinpro

    Prophylaxis, washing and removing water excess , apply the Clinpro forming a uniform layer of 0.5mm, lightcure for 20 seconds

  • Potassium Nitrate 2%Drug

    Also called Desensibilize KF

    Prophylaxis, apply uniformly on the teeth, wait 10 minutes, remove the gel from the teeth with cotton and abundant water.

  • Low level laser therapyProcedure or surgery

    Also called Photon Lase III

    Prophylaxis, applying infrared laser at low power in points: mesial, buccal, distal and in the apical point in the foyer of fornix with power of 110MW for 11 seconds at each point.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Level of cervical dentin hypersensitivity, measured by visual analog scale (time frame: 24 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 NCT02931734, which also lists 8 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?
