Brief summary
The objective of this clinical study is to evaluate the efficacy of multi-component oral hygiene regimens as adjunctive to non-surgical periodontal treatment in patients with stage II periodontitis.
Detailed description
This is a Phase III, multicenter, controlled, randomized, double-blind clinical trial with two parallel arms. A total of 100 participants, aged 30 to 70, diagnosed with stage II generalized periodontitis will undergo non-surgical periodontal treatment and be randomized to one of two at-home oral hygiene regimens. Participants will be monitored over a 12-month period to assess clinical periodontal parameters.
Interventions
Participants use a 0.12% chlorhexidine mouthwash and stannous fluoride toothpaste for 3 weeks (Regimen I). Afterwards, they switch to a 0.09% CPC and 0.28% Zinc Lactate mouthwash with fluoride and stannous fluoride toothpaste (Regimen II). Both regimens include a soft bristle toothbrush and dental floss.
Participants use a fluoride placebo mouthwash, standard fluoride toothpaste, soft bristle toothbrush, and dental floss for the duration of the study.

Masking description
All products will be covered with white over-wrapping in order to conceal product identity. The examining dentist and their staff will remain blinded to product assignments.
Eligibility
Inclusion criteria
* Males and females, between 30-70 years of age, inclusive. * Good general health. Minimum of 15 uncrowned permanent natural teeth (excluding third molars and crowns). * Clinical diagnosis of stage II generalized periodontitis.
Exclusion criteria
* Periodontal treatment undergone 3 months before the beginning of the study. - Mucosal oral pathology. * Uncontrolled systemic chronic disease that may interfere with host response. - Use of anti-inflammatory and antibiotic within 3 months prior to the start of the study, scheduled to start such intake during the treatment phase, or use of therapeutic mouthwash within the last three months. * Need for antibiotic prophylaxis. * Participation in any other clinical study. * Pregnant, breastfeeding, or intended to get pregnant during the study. * Allergic to oral care products, personal care consumer products, or their ingredients. * Ongoing use of medications known to affect the gingival tissues (e.g., calcium channel blockers, phenytoin, cyclosporine). * Current smokers and subjects with a history of alcohol or drug abuse. - Orthodontic appliances or presence of fixed or removable prosthodontics dentures that may interfere with the evaluations.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pocket depth (PD) reduction | Baseline, 3 months, 6 months, 9 months, and 12 months post-treatment | The distance measured between the gingival margin and the bottom of the gingival sulcus or the periodontal pocket, assessed at six sites per tooth using a calibrated periodontal probe. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in subgingival microbiological composition | Baseline, 3 weeks, 3 months, 6 months, 9 months, and 12 months post-treatment | Subgingival plaque collected via sterile curette and analyzed by qPCR to determine total and relative bacterial quantification. |
| Change in levels of immunological mediators in gingival crevicular fluid (GCF) | Baseline, 3 weeks, 3 months, 6 months, 9 months, and 12 months post-treatment | GCF collected via sterile paper strips and analyzed for host biomarkers using enzyme-linked immunosorbent assay (ELISA) techniques |
| Change in Gingival Index (GI) | Baseline, 3 weeks, 3 months, 6 months, 9 months, and 12 months post-treatment | Evaluated using the Löe-Silness Gingival Index (score 0-3) on all scorable surfaces to determine a whole mouth mean score representing gingival inflammation and bleeding. |
| Change in Plaque Index (PI) | Baseline, 3 weeks, 3 months, 6 months, 9 months, and 12 months post-treatment | Evaluated using the Löe \& Silness Plaque Index (score 0-3) on all scorable surfaces to determine a whole mouth mean score representing microbial plaque accumulation. |
| Clinical Attachment Level (CAL) gain | Baseline, 3 months, 6 months, 9 months, and 12 months post-treatment | The distance measured between the cemento-enamel junction and the bottom of the gingival sulcus or periodontal pocket, assessed at six sites per tooth. |
| Number of residual pockets | 3 months, 6 months, 9 months, and 12 months post-treatment | The quantity of sites exhibiting residual pockets (PD \>= 4 mm with bleeding on probing). |
| Change in Bleeding on Probing (BOP) | Baseline, 3 months, 6 months, 9 months, and 12 months post-treatment | Evaluated using the Ainamo \& Bay Index, scoring the presence or absence of bleeding in the gingival sulcus after gentle probing, expressed as a percentage of bleeding sites over total sites. |
