Frequency of Self-performed Mechanical Control of Plaque

March 31, 2016 updated by: Juliana Maier, Universidade Federal de Santa Maria

Effect of Self-performed Mechanical Control of Plaque Frequency in Patients With Historic of Periodontitis and in Maintenance

The purpose of this blind randomized clinical trial is to evaluate different frequencies in self-mechanical control of plaque in individuals with historic of periodontitis and in periodic and preventive maintenance in order to assess which frequencies are compatible with maintaining gingival health.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Thirty nine subjects with at most 5% of the sites for GI= 2 (gingival health) will be randomized into three groups with different frequencies in self-mechanical control of plaque: Group 12 hours, 24 hours and 48 hours. The exams of plaque index, gingival index, probing depth, bleeding on probing, clinical attachment level and gingival crevicular fluid will be performed at baseline, 15, 30, 60 and 90 days.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

31 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes from baseline gingival index at 30, 60 and 90 days.
Time Frame: 30,60 and 90 days.
Assess how different frequencies of self-performed mechanical control of plaque interfere in gingival status.
30,60 and 90 days.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes from baseline plaque level at 30,60 and 90 days.
Time Frame: 30,60 and 90 days.
  • Assess how different frequencies of self-performed mechanical control of plaque interfere in the accumulation of supragingival biofilm.
  • Correlate changes in plaque levels with changes in gingival index.
30,60 and 90 days.
Changes from volume of gingival fluid at 30,60 and 90 days.
Time Frame: 30,60 and 90 days.
  • Assess how different frequencies of self-performed mechanical control of plaque interfere in the volume of gingival fluid.
  • Correlate volume of gingival fluid with GI scores and bleeding on probing scores.
30,60 and 90 days.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
