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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Control group: Dental model
Patients diagnosed with periodontal disease stage I/II/III
Behavioral: Control group: Dental Model
- Patients receive a demonstration of plaque control methods (modified Bass dental brushing technique and the use of the electric toothbrush) using a dental model.
Computer-assisted teaching format group
Patients diagnosed with periodontal disease stage I/II/III
Behavioral: Computer-assisted teaching format group
- Patients receive a Powerpoint presentation containing:
Plaque-disclosing group
Patients diagnosed with periodontal disease stage I/II/III
Behavioral: Plaque-disclosing group
- Patients place a few drops of a plaque-disclosing solution on the tongue and run the tongue over all the teeth and gums. With the aid of a hand mirror, patients can observe the stained plaque residue on their teeth
Intra-oral Camera group
Patients diagnosed with periodontal disease stage I/II/III
Behavioral: Intra-oral camera group
- An ACTEON Soprocare® intraoral camera is used during the examination and explanation of oral hygiene strategies.

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
Evaluation of the plaque index
Time Frame: 3 months

Plaque Index (Loë and Silness, 1963): Six surfaces per tooth (buccal, mesio-buccal, disto-buccal, lingual, mesio-lingual and disto-lingual) are examined in every permanent tooth (except for third molars).

Each tooth is assessed with a score between 0 and 3.

  • 0 : absence of dental plaque
  • 1 : plaque disclosed after running the periodontal probe along the gingival margin
  • 2: visible plaque; absence of plaque in the interdental spaces
  • 3: abundant plaque; presence of plaque in the interdental spaces
3 months
Evaluation of the gingival index
Time Frame: 3 months

Gingival Index (Loë 1967):

Six surfaces per tooth (buccal, mesio-buccal, disto-buccal, lingual, mesio-lingual and disto-lingual) are examined in every permanent tooth (except for third molars).

  • 0: absence of visual signs of inflammation
  • 1 : slight change in color and texture o 2: Visual inflammation and bleeding tendency from the gingival margin right after a periodontal probe is briefly run along the gingival margin
  • 3: Overt inflammation with tendency for spontaneous bleeding
3 months

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
Evaluation of probing pocket depth
Time Frame: 3 months
Probing pocket depth (distance from the top of the marginal gingiva to the bottom of the pocket)
3 months
Evaluation of the gingival attachment level
Time Frame: 3 months
Gingival attachment level (distance separating the cemento-enamel junction from the bottom of the pocket)
3 months
Psychological determinants of the HAPA (Health Action Process Approach)
Time Frame: 3 months
Change in the psychological determinants of the HAPA questionnaire adapted to oral health, using a 7-point Likert scale from "strongly disagree" (1) to "strongly agree" (7)
3 months
