Study summary

This is a randomized controlled clinical trial (RCT). After signing the informed consent, patients satisfying the inclusion criteria will undergo supragingival and subgingival professional oral hygiene of both arches performed with ultrasonic instrumentation with PEEK inserts, manual instrumentation with PEEK curettes and air polishing with glycine powder.

After that, the sample will be randomly divided into 2 groups based on the domiciliary assigned treatment:

  • Aftoral® Oral Gel solution with Hyaluronic Acid, Xylitol and glycerophosphoinositol for the domiciliary use for 15 days for 2 peri-implant mucositis sites.
  • Unidea® Chlorhexidine digluconate Mouthwash 0,20% administration for the domiciliary application for 15 days for 2 peri-implant sites.

The study will last 6 months. Patients will be visited at: T0, after 1 month from T0 (T1), after 3 months (T2), after 6 months (T3), after 9 months (T4) and after 12 months (T5). Professional hygiene will be performed again at T3.

At each recall session were collected a satisfaction questionnaire of the products (taste, smell, consistency, persistence and ease of application) and the following periodontal clinical indices, using a PEEK probe on each peri-implant site:

  • conditions of the marginal mucosa (swelling and erythema),
  • migration of the marginal mucosa,
  • PPD (Probing Pocket Depth),
  • BOP% (Bleeding on Probing),
  • BS (Bleeding Score),
  • Suppuration,
  • PCR% (Plaque Control Record),

What researchers measure

Primary outcomes

  1. Change in Probing Depth (PD)

    Evaluation (in mm) of the depth of the gingival sulcus, through a millimeter periodontal PEEK probe; it is detected from the gingival margin to the bottom of the gingival sulcus or periodontal pocket, evaluated at 6 sites.

    Time frame: Baseline (T0), after 1 (T1), 3 (T2), 6 (T3), 9 (T4) and 12 months (T5)

  2. Change in Bleeding on Probing (BOP%)

    Quantitative assessment (percentage) of the bleeding sites (6 per tooth in total). Formula = n ° bleeding sites / n ° probed sites x100

    Time frame: Baseline (T0), after 1 (T1), 3 (T2), 6 (T3), 9 (T4) and 12 months (T5)

  3. Change in Bleeding Score (BS - Mombelli et al.)

    Scoring criteria: 0: no bleeding 1. isolated visible spots 2. blood forms a confluent red line on the mucosal margin 3. profuse and copious bleeding

    Time frame: Baseline (T0), after 1 (T1), 3 (T2), 6 (T3), 9 (T4) and 12 months (T5)

  4. Change in Plaque Control Record (PCR%)

    Evaluation of the presence of plaque on the 4 surfaces of teeth on the total amount of dental surfaces. Formula = n ° sites with plaque / total n ° of dental surfaces x100

    Time frame: Baseline (T0), after 1 (T1), 3 (T2), 6 (T3), 9 (T4) and 12 months (T5)

  5. Change in marginal mucosa condition

    Scoring criteria: 0: normal mucosa 1. minimal inflammation with color change and minor edema 2. moderate inflammation with redness, edema and glazing 3. severe inflammation with redness, edema, ulceration and spontaneous bleeding without probing

    Time frame: Baseline (T0), after 1 (T1), 3 (T2), 6 (T3), 9 (T4) and 12 months (T5)

  6. Change in Suppuration (%)

    Dichotomous scoring (yes/no) of suppurating sites

    Time frame: Baseline (T0), after 1 (T1), 3 (T2), 6 (T3), 9 (T4) and 12 months (T5)

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.
No changes since tracking began. The registry record was last updated on Jun 25, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
