Brief summary
A retrospective, observational, non-profit study designed to evaluate the use of the H42 medical device in patients with periodontitis or peri-implantitis. The study included adult subjects aged 25 to 65 years with peri-implant or periodontal pockets with probing depths (PD) between 5 and 8 mm and 1-5 defects, treated with H42® according to standard clinical practice. The primary outcome involved comparing the periodontal parameters-Periodontal Pocket Depth (PPD), Plaque Index (PI), Clinical Attachment Level (CAL), and Sulcus Bleeding Index (SBI)-before the application of H42 (baseline) and at follow-up visits after 30 and 90 days. The secondary outcomes, on the other hand, assessed soft tissue healing, pain levels via Numeric Rating Scale (NRS 0-10), recurrence of infection, and any unexpected side effects observed. These parameters were assessed at 7, 14, 21, 30, and 90 days after the use of H42.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Periodontal Pocket Depth (PPD) at 30 and 90 days | Baseline before H42 treatment; 30 days and 90 days after H42 treatment. | PPD defined as the distance, measured in millimeters (mm) from the gingival margin to the bottom of the gingival sulcus/pocket. |
| Change from Baseline in Plaque Index (PI) at 30 and 90 days | Baseline before H42 treatment; 30 days and 90 days after H42 treatment. | PI will be used to evaluate the presence and thickness of plaque at the gingival margin. Scoring is based on the Silness and Löe Plaque Index criteria on a scale from 0 to 3, where: 0 = no plaque; 1 = a film of plaque adhering to the free gingival margin and adjacent area of the tooth, recognized only by running a probe across the tooth surface; 2 = moderate accumulation of soft deposits within the gingival pocket, or on the tooth and gingival margin, visible to the naked eye; 3 = abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin. Higher scores indicate greater plaque accumulation. The final value represents the patient's average score across all examined surfaces. |
| Change from Baseline in Clinical Attachment Level (CAL) at 30 and 90 days | Baseline before H42 treatment; 30 days and 90 days after H42 treatment. | CAL will be evaluated to assess periodontal tissue regeneration. Measurement is calculated using the formula: CAL = PPD - (CEJ to FGM distance), where PPD is Probing Pocket Depth, CEJ is Cemento-Enamel Junction, and FGM is Free Gingival Margin. Measurements will be taken in millimeters (mm). |
| Change from Baseline in Sulcus Bleeding Index (SBI) at 30 ad 90 days | Baseline before H42 treatment; 30 days and 90 days after H42 treatment. | SBI evaluated as ordinal variable with a scale from 0 to 5, where: 0 = gingiva of normal texture, color, no bleeding; 1 = gingiva apparently normal, bleeding on probing; 2 = bleeding on probing, color change, no edema; 3 = bleeding on probing, color change, slight edema; 4 = either bleeding on probing, color change, obvious edema; 5 = spontaneous bleeding on probing, color change. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Patient-Reported Pain Score at five predefined follow-up timepoint | Baseline before H42 treatment and at 7, 14, 21, 30, and 90 days after the use of H42. | Patient-reported pain will be assessed using an 11-point Numeric Rating Scale (NRS). The scale ranges from 0 to 10, where 0 indicates "no pain" and 10 indicates "the worst possible pain". Higher scores represent greater pain intensity. |
| Change from baseline in inflammation grade at five predefined follow-up timepoints | Baseline before H42 treatment and at 7, 14, 21, 30, and 90 days after the use of H42. | Inflammation was assessed using the Gingival Index (GI), a scale ranging from 0 to 3, where GI = 0 indicates the absence of inflammation, GI = 1 indicates mild inflammation, GI = 2 indicates moderate inflammation, and GI = 3 indicates severe inflammation. Higher scores indicate greater nflammation. |
| Change from Baseline in soft tissue healing at five predefined follow-up timepoint | Baseline before H42 treatment and at 7, 14, 21, 30, and 90 days after the use of H42. | Soft tisssue healing was assessed using a scale ranging from 0 to 3, where 0 indicates the absence of healing, 3 indicates severe healing. |
