Clinical Trial 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.

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)

Intervention

Other:
• Ozoral Pro and Ozoral gel administration
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).
• Curasept chlorhexidine gel 1%
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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Bleeding on Probing (BOP%)	Dichotomous scoring (yes/no) of bleeding sites	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in Gingival Bleeding Index (GBI%)	Quantitative assessment (percentage) of the bleeding sites (6 per tooth in total).; Formula = n ° bleeding sites / n ° probed sites x100	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in Suppuration (%)	Dichotomous scoring (yes/no) of suppurating sites	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in marginal mucosa condition	Scoring criteria: 0: normal mucosa; minimal inflammation with color change and minor edema; moderate inflammation with redness, edema and glazing; severe inflammation with redness, edema, ulceration and spontaneous bleeding without probing	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in mucosal margin	Dichotomous scoring (migrated/non migrated)	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in Probing Depth (PD)	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.	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in Plaque Index (PI% - O' Leary Index)	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	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Primary	Change in Bleeding Score (BS - Mombelli et al.)	Scoring criteria: 0: no bleeding; isolated visible spots; blood forms a confluent red line on the mucosal margin; profuse and copious bleeding	Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
