What is being measured

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

Gingival Severity Index (GSI) Based on the Gingival Index (GI)
Measure of gingival severity averaged across whole mouth site; each site scored 0, 1, 2, 3 based on GI and,
1. GSI = 0 if GI is 0 or 1 (no bleeding)
2. GSI = 1 if GI is 1 or 2 (bleeding)
Measured: Change from baseline to 6 weeks

Secondary outcomes (3)

Gingival Index
The GI was assessed on the facial and lingual surfaces at six sites on each tooth (facial and lingual - distal papillae, margin and mesial papillae). These assessments were performed on all evaluable teeth using moderate pressure sweeping a blunt ended probe, which was engaged in approximately 1 millimetre (mm) into the gingival crevice. The scores could range from 0-3 (0=Absence of inflammation; 1=Mild Inflammation-Slight change in color slight change in texture, no bleeding on probing; 2=Moderate Inflammation -glazing, redness edema and hypertrophy, bleeding on probing; 3= Severe inflammation-marked redness and hypertrophy, tendency for spontaneous bleeding)
Measured: Change from baseline to 6 weeks
Turesky Modification of Quigley & Hein Plaque Index for Overall Plaque Scores
Overall plaque scores were calculated taking the average over all tooth sites for a participant. The scores could range from 0-5 (0=No plaque; 1=Slight flecks of plaque at the cervical margin of the tooth; 2= A thin continuous band of plaque (1 mm or smaller) at the cervical margin of the tooth; 3=A band of plaque wider than 1 mm but covering less than 1/3 of the area to be graded of the crown of the tooth; 4=Plaque covering at least 1/3 but less than 2/3 of the area to be graded of the crown of the tooth; 5=Plaque covering 2/3 or more of the area to be graded of the crown of the tooth)
Measured: Change from baseline to 6 weeks
Turesky Modification of Quigley & Hein Plaque Index for Interproximal Plaque Scores
Interproximal plaque scores were analyzed on the mesiofacial, distofacial, mesiolingual and distolingual surfaces, and calculated taking the average over all tooth sites for a participant. The scores could range from 0-5 (0=No plaque; 1=Slight flecks of plaque at the cervical margin of the tooth; 2= A thin continuous band of plaque (1 mm or smaller) at the cervical margin of the tooth; 3=A band of plaque wider than 1 mm but covering less than 1/3 of the area to be graded of the crown of the tooth; 4=Plaque covering at least 1/3 but less than 2/3 of the area to be graded of the crown of the tooth; 5=Plaque covering 2/3 or more of the area to be graded of the crown of the tooth)
Measured: Change from baseline to 6 weeks

Questions about this trial

What is this clinical trial studying?

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 9 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 28 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United Kingdom. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Jul 2014). 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?

Gingival Severity Index (GSI) Based on the Gingival Index (GI) (time frame: Change from baseline to 6 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 NCT01751178.

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 28 Jul 2014; AzTrials last refreshed its copy on 6 Nov 2026.
