Study summary

The objective of this observational study is to assess the correlation between the severity of periodontal involvement and masticatory performance in patients with periodontitis.

The secondary objectives are to identify periodontal parameters that may be associated with a reduction in masticatory performance.

This study includes a single group.

Participants will be asked to perform a masticatory performance test consisting of chewing a piece of gum for 20 cycles.

Read the detailed description

The study will be conducted over a one-year period. Patients diagnosed with periodontitis during their treatment within the Department of Dentistry will be invited to participate in the study. After being provided with clear information about the study and after their lack of objection has been recorded, they will be asked to undergo a masticatory performance test consisting of chewing a piece of chewing gum. The chewing gum samples collected at the end of this test will be analyzed in the CROC laboratory to determine a masticatory performance value. All collected data will then be analyzed to address the study objectives.

What researchers measure

Primary outcomes

  1. Value of the patient's masticatory performance

    Value of the patient's masticatory performance, obtained from the masticatory performance test (two-color chewing gum test) (quantitative variable).

    Time frame: Baseline

Secondary outcomes

  1. Severity of periodontal disease assessed by stage.

    Stage of periodontitis according to the Chicago classification. Categorical (Stage 1 (early-stage periodontitis) to Stage 4 (severe periodontitis) as defined by classification)

    Time frame: Baseline (T0)

  2. Pocket Depth

    Periodontal probing depth. Unit of Measure: Millimeters (mm)

    Time frame: Baseline

  3. Gingival recessions

    Measurement of gingival recession depth. Unit of Measure : Millimeters (mm)

    Time frame: Baseline

  4. Bleeding on Probing (BOP)

    Percentage (%) of sites showing bleeding on probing.

    Time frame: Baseline

  5. Plaque Index

    Plaque accumulation assessed using a validated plaque index (specify full name of index).

    Time frame: Baseline

  6. Tooth Mobility

    Tooth mobility assessed using the Miller classification (Grade 0-3). Higher scores indicate greater mobility and worse periodontal condition. Unit of Measure: Millimeters (mm)

    Time frame: Baseline

  7. Edentulism

    Presence or absence of edentulism.

    Time frame: Baseline

Started Oct 2026 (actual). Primary completion is estimated for Oct 2027, 12 months after the start.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 16, 2026: start Sep 2026 → Oct 2026, primary completion Sep 2027 → Oct 2027 and completion Sep 2027 → Oct 2027.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
