About this study

Official title: Cleansing Efficacy of Waist-shaped Interdental Brushes. A Randomized-controlled Crossover Study.

The aim of the present randomized and single-blinded cross-over study was to compare the cleansing efficacy of waist-shaped interdental brushes with that of cylindric interdental brushes in interproximal sites.

Read the detailed description

Brushing efficacy of cylindric and waist-shaped interdental brushes was evaluated in a randomized, controlled, examiner-blinded, two-period crossover study. 20 periodontal maintenance patients of the University Hospital of Dental Prosthetics and Restorative Dentistry were recruited. Each subject was asked to attend three appointments. In the first visit (day one), baseline plaque and bleeding indices were assessed. Each proband was instructed by the same experienced dental hygienist with two sizes of waist-shaped and cylindric interdental brushes, respectively. Primary outcome measure plaque index and secondary outcome measure papillary bleeding index were assessed by two blinded and calibrated examiners at four sites per tooth.The odds ratio and confidence interval for establishing plaque free interdental sites were calculated with logistic regression analysis.

What is being measured

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

  1. Turesky modification of the Quigley and Hein Plaque Index

    This is a plaque index scored as 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 < 1/3 of the crown of the tooth; 4 = plaque covering at least 1/3 but < 2/3 of the crown of the tooth or 5 = plaque covering 2/3 or more of the crown of the tooth. A higher grade is worse (more plaque) than a lower grade. After measuring plaque grades on four sites per tooh, the mode is calculated, which is defined as the plaque grade most often measured in an individual.

    Measured: 11 weeks

Secondary outcomes (1)
  1. papillary bleeding index by Saxer and Mühlemann

    A periodontal probe is inserted into the gingival sulcus at the line angle on the mesial and distal aspect of the papilla and then moved coronally to the papilla tip (score 0 - no bleeding; score 1 - a single discreet bleeding point; score 2 - several isolated bleeding points or a single line of blood; score 3 - the interdental triangle fills with blood; score 4 - profuse bleeding occurs after probing and flows immediately into the marginal sulcus). A higher bleeding grade is worse (more inflammed tissues) than a lower grade. After measuring papillary bleeeding grades on four sites per tooh, the mode is calculated, which is defined as the papillary bleeding grade most often measured in an individual.

    Measured: 11 weeks

Questions about this trial

What is this clinical trial studying?

A study testing waist-shaped interdental brush and cylindric interdental brush in people with Periodontitis, Adult, run by Medical University Innsbruck at 1 site in Austria.

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 7 inclusion and 5 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 22 Feb 2019. 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 Austria. 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?

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?

Turesky modification of the Quigley and Hein Plaque Index (time frame: 11 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 NCT03851757, which also lists 4 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Feb 2019.
