Evaluation of Masticatory Performance in Patients With Periodontitis

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.

About this study

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.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients followed at the university hospital (CHU) with a diagnosis of periodontitis.
  • No objection from the patient to participate in the study.
  • Patients able to speak and understand French.

Exclusion criteria

  • Patients who refuse to participate in the study.

Treatment and study plan

Primary outcomes

  1. Value of the patient's masticatory performance

    Time frame: Baseline

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

Secondary outcomes

  1. Severity of periodontal disease assessed by stage.

    Time frame: Baseline (T0)

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

  2. Pocket Depth

    Time frame: Baseline

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

  3. Gingival recessions

    Time frame: Baseline

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

  4. Bleeding on Probing (BOP)

    Time frame: Baseline

    Percentage (%) of sites showing bleeding on probing.

  5. Plaque Index

    Time frame: Baseline

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

  6. Tooth Mobility

    Time frame: Baseline

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

  7. Edentulism

    Time frame: Baseline

    Presence or absence of edentulism.
