What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adjusted Mean Change From Baseline in Tooth Hypersensivity to Air Stimuli Immediately Following Treatment

    Response to a constant (duration, pressure, temperature, distance from target) jet of air applied to a hypersensitive tooth was evaluated using Schiff Cold Air Sensitivity Scale. According to this analog scale hypersensitivity scores for the stimulated tooth is 0, 1, 2 or 3 (lower the score, lower the hypersensitivity).0= no response; 1= response and no discontinuation request; 2= response and discontinuation request; 3= painful response and discontinuation request. Change was calculated as Schiff score immediately after treatment minus Schiff score at baseline.

    Measured: Baseline and immediately after treatment administration

Secondary outcomes (5)
  1. Adjusted Mean Change From Baseline in Tooth Hypersensitivity to Air Stimuli at Day 3

    Response to a constant (duration, pressure, temperature, distance from target) jet of air applied to a hypersensitive tooth evaluated using Schiff Cold Air Sensitivity Scale. According to this analog scale hypersensitivity scores for the stimulated tooth is 0, 1, 2 or 3 (lower the score, lower the hypersensitivity). 0=No participant response to stimulus, 1=responds but will continue, 2=responds and moves or requests discontinuation, 3=Painful response to stimulus, discontinuation requested. Change was Schiff score on Day 3 minus Schiff score at baseline.

    Measured: Baseline and Day 3

  2. Adjusted Mean Change From Baseline in Tooth Hypersensitivity to Air Stimuli at Day 14

    Response to a constant (duration, pressure, temperature, distance from target) jet of air applied to a hypersensitive tooth evaluated using Schiff Cold Air Sensitivity Scale. According to this analog scale hypersensitivity scores for the stimulated tooth is 0, 1, 2 or 3 (lower the score, lower the hypersensitivity). 0=No participant response to stimulus, 1=responds but will continue, 2=responds and moves or requests discontinuation, 3=Painful response to stimulus, discontinuation requested. Change was Schiff score on Day 14 minus Schiff score at baseline.

    Measured: Baseline and Day 14

  3. Adjusted Mean Change From Baseline in Tooth Hypersensitity to Touch Stimuli (Tactile) Immediately After Treatment

    Measured with an electronic force sensing probe (Yeaple Probe): 10, 20, 30, 40, up to 80 grams of force applied to hypersensitive tooth until pain was elicited. Grams of force needed to elicit pain was recorded as hypersensitivity score for the tooth. The higher the score, the lower the hypersensitivity. Hypersensitivity scores on a per study participant basis was recorded as mean scores of all hypersensitive teeth. Change was calculated as mean score immediately after treatment minus mean score at baseline.

    Measured: Baseline and immediately after treatment administration

  4. Adjusted Mean Change From Baseline in Tooth Hypersensitity to Touch Stimuli (Tactile) Immediately at Day 3

    Measured with an electronic force sensing probe (Yeaple Probe): 10, 20, 30, 40, up to 80 grams of force applied to hypersensitive tooth until pain was elicited. Grams of force needed to elicit pain was recorded as hypersensitivity score for the tooth. The higher the score, the lower the hypersensitivity. Hypersensitivity scores on a per study participant basis was recorded as mean scores of all hypersensitive teeth. Change was calculated as mean score at Day 3 minus mean score at baseline.

    Measured: Baseline and Day 3

  5. Adjusted Mean Change From Baseline in Tooth Hypersensitity to Touch Stimuli (Tactile) Immediately at Day 14

    Measured with an electronic force sensing probe (Yeaple Probe): 10, 20, 30, 40, up to 80 grams of force applied to hypersensitive tooth until pain was elicited. Grams of force needed to elicit pain was recorded as hypersensitivity score for the tooth. The higher the score, the lower the hypersensitivity. Hypersensitivity scores on a per study participant basis was recorded as mean scores of all hypersensitive teeth. Change was calculated as mean score at Day 14 minus mean score at baseline.

    Measured: Baseline and Day 14

Questions about this trial

What is this clinical trial studying?

A study testing Test Toothpaste in people with Dentinal Sensitivity and Hypersensitivity, run by GlaxoSmithKline at 1 site in United States.

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 12 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?

The record says: finished, as of the sponsor's last update on 8 May 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 May 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Adjusted Mean Change From Baseline in Tooth Hypersensivity to Air Stimuli Immediately Following Treatment (time frame: Baseline and immediately after treatment administration). 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 NCT01494649, which also lists 1 linked publication.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2013.
