ORAL HYGIENE, PERIODONTAL STATUS AND QUALITY OF LIFE

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.

Treatment and study plan

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.

Primary outcomes

  1. Oral health-related quality of life (OSHIP-Perio score)

    Time frame: Baseline (single visit)

    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.

Secondary outcomes

  1. Probing Pocket Depth (PPD)

    Time frame: Baseline (single visit)

    Probing pocket depth (PPD) will be measured in millimeters using a calibrated periodontal probe at six sites per tooth.

  2. Periodontitis Stage (2017 Classification)

    Time frame: Baseline (single visit)

    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.

  3. Clinical Attachment Level (CAL)

    Time frame: Baseline (single visit)

    Clinical attachment level (CAL) will be measured in millimeters using a periodontal probe at six sites per tooth.

  4. Bleeding on Probing (BOP)

    Time frame: Baseline (single visit)

    Bleeding on probing (BOP) will be assessed as the presence or absence of bleeding within 15 seconds after probing and recorded as percentage (%).

  5. Periodontitis Grade (2017 Classification)

    Time frame: Baseline (single visit)

    Periodontitis grade will be determined according to the 2017 World Workshop Classification, based on rate of progression, risk factors, and clinical parameters.
