Peri-implant Mucositis
Conditions
Brief summary
This is a split-mouth 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 titanium curettes and air polishing with glycine powder. After that, the following treatment will be randomly assigned: * Ozoral Pro and Ozoral gel administration and home application for 2 peri-implant mucositis sites. * Curasept chlorhexidine gel 1% administration and domiciliary application for 14 days for 2 peri-implant contralateral 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). Professional hygiene will be performed again at T2 and T3. At each recall session, the following periodontal clinical indices were collected using a probe on each peri-implant site: BOP, GBI, conditions of the marginal mucosa (swelling and erythema), suppuration, migration of the marginal mucosa, PD, PI ,BS.
Detailed description
This is a split-mouth randomized controlled clinical trial (RCT). 30 patients is expected to be enrolled. 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 titanium curettes and air polishing with glycine powder. After that, the following treatment will be randomly assigned: * Ozoral Pro and Ozoral gel administration and home application for 2 peri-implant mucositis sites. * Curasept chlorhexidine gel 1% administration and domiciliary application for 14 days for 2 peri-implant contralateral sites. The study will last 6 months. Patients will be visited at: T0, after 1 month from T0 (T1), after 3 months (T2), and after 6 months (T3). At T2 and T3, professional hygiene will be performed again. At each recall session, the following periodontal clinical indices were collected using a probe on each peri-implant site: BOP (bleeding on probing) and GBI (gingival bleeding index) Conditions of the marginal mucosa (swelling and erythema) Suppuration Migration of the marginal mucosa PD (probing depth) PI (plaque index) BS (bleeding score)
Interventions
Peri-implant mucositis sites will receive in-office Ozoral Pro administration after non-surgical therapy. Patients will use Ozoral Gel for the domiciliary administration once a day for 14 days after the visits (no rinsing and eating for 30 minutes after gel application).
Peri-implant mucositis sites will receive in-office Curasept chlorhexidine gel 1% administration after non-surgical therapy. Patients will use chlorhexidine gel 1% for the domiciliary application once a day for 14 days after the visits (no rinsing and eating for 30 minutes after gel application).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Bleeding on Probing (BOP%) | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | Dichotomous scoring (yes/no) of bleeding sites |
| Change in Gingival Bleeding Index (GBI%) | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | Quantitative assessment (percentage) of the bleeding sites (6 per tooth in total). Formula = n ° bleeding sites / n ° probed sites x100 |
| Change in Suppuration (%) | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | Dichotomous scoring (yes/no) of suppurating sites |
| Change in marginal mucosa condition | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | 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 |
| Change in mucosal margin | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | Dichotomous scoring (migrated/non migrated) |
| Change in Probing Depth (PD) | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | Evaluation (in mm) of the depth of the gingival sulcus, through a millimeter periodontal probe; it is detected from the gingival margin to the bottom of the gingival sulcus or periodontal pocket, evaluated at 6 sites. |
| Change in Plaque Index (PI% - O' Leary Index) | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | 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 |
| Change in Bleeding Score (BS - Mombelli et al.) | Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3) | 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 |
