This cross-sectional study aims to evaluate the relationship between oral hygiene habits, periodontal status, and oral health-related quality of life in adult individuals. A total of approximately 160 participants attending the Department of Periodontology will be included. Periodontal status will be assessed using standard clinical parameters, including probing depth, clinical attachment loss, bleeding on probing, and plaque index. In addition, the Periodontal Inflamed Surface Area (PISA) will be calculated to quantify inflammatory burden. Oral health-related quality of life will be evaluated using the OSHIP-Perio questionnaire, a validated patient-reported outcome measure specific to periodontal conditions. The study will investigate the association between clinical periodontal findings, oral hygiene practices, and quality of life outcomes. The findings are expected to provide a comprehensive understanding of both clinical and patient-centered aspects of periodontal disease and contribute to improved individualized treatment approaches.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| PERIODONTITIS PATIENTS | Patients with a diagnosis of periodontitis, irrespective of its stage and grade.This group will include individuals diagnosed with periodontitis, characterized by interdental clinical attachment loss (CAL) at ≥2 non-adjacent teeth and/or buccal/oral CAL ≥3 mm with pocketing >3 mm at ≥2 teeth, not attributable to non-periodontal causes. Participants will present with increased probing pocket depths (PPD ≥4 mm), bleeding on probing (BOP), and radiographic evidence of alveolar bone loss. The diagnosis and staging of periodontitis will be established according to the criteria defined by the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. |
| |
| GINGIVITIS PATIENTS | This group will include individuals diagnosed with gingivitis, characterized by the presence of gingival inflammation without clinical attachment loss or radiographic evidence of alveolar bone loss. Participants will exhibit bleeding on probing (BOP) ≥10%, with probing pocket depths (PPD) ≤3 mm at all sites. The diagnosis of gingivitis will be established according to the criteria defined by the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. |
| |
| periodontally healthy individuals | This group will consist of systemically healthy individuals presenting with clinically healthy periodontal tissues. Participants will have no clinical signs of gingival inflammation, no periodontal pocket formation, no clinical attachment loss (CAL), and no radiographic evidence of alveolar bone loss. All individuals in this group will demonstrate probing pocket depths (PPD) ≤3 mm at all sites and bleeding on probing (BOP) <10%, in accordance with the criteria defined by the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. |

| Oral Health Assessment and OSHIP-Perio Questionnaire | Other | Participants will undergo a comprehensive periodontal clinical examination, including assessment of probing pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), and plaque and gingival indices. In addition, participants will complete the OSHIP-Perio questionnaire to evaluate the impact of periodontal status on oral health-related quality of life. No invasive or therapeutic intervention will be performed as part of this study. |
| Measure | Description | Time Frame |
|---|---|---|
| Oral health-related quality of life (OSHIP-Perio score) | The primary outcome is the Oral and Systemic Health Impact Profile for Periodontal Disease (OSHIP-Perio) total score obtained from a 21-item questionnaire assessing the impact of periodontal status on oral health-related quality of life. | Baseline (single visit) |
| Measure | Description | Time Frame |
|---|---|---|
| Probing Pocket Depth (PPD) | Probing pocket depth (PPD) will be measured in millimeters using a calibrated periodontal probe at six sites per tooth. | Baseline (single visit) |
| Periodontitis Stage (2017 Classification) |

Periodontitis stage will be determined according to the 2017 World Workshop Classification of Periodontal Diseases, based on clinical attachment loss, radiographic bone loss, and tooth loss.
| Baseline (single visit) |
| Clinical Attachment Level (CAL) | Clinical attachment level (CAL) will be measured in millimeters using a periodontal probe at six sites per tooth. | Baseline (single visit) |
| Bleeding on Probing (BOP) | Bleeding on probing (BOP) will be assessed as the presence or absence of bleeding within 15 seconds after probing and recorded as percentage (%). | Baseline (single visit) |
| Periodontitis Grade (2017 Classification) | Periodontitis grade will be determined according to the 2017 World Workshop Classification, based on rate of progression, risk factors, and clinical parameters. | Baseline (single visit) |
