About this study
Official title: Evaluatıon Of The Relatıonshıp Between Perıodontal Inflammatıon Severıty And Pan-Immune System Inflammatıon Value
This cross-sectional observational study aims to evaluate the relationship between periodontal inflammation severity and the Pan-Immune-Inflammation Value (PIV) in systemically healthy adults. A total of 160 participants will be recruited from the Department of Periodontology, Faculty of Dentistry, Bolu Abant Izzet Baysal University. Clinical periodontal parameters and Periodontal Inflamed Surface Area (PISA) will be recorded, and their association with PIV calculated from complete blood count parameters will be analyzed.
Read the detailed description
Periodontitis is a chronic inflammatory disease that leads to progressive destruction of the tooth-supporting tissues and contributes to systemic inflammatory burden. Periodontal Inflamed Surface Area (PISA) is a validated quantitative measure that estimates the total inflamed periodontal surface area and reflects the inflammatory burden associated with periodontal disease.
The Pan-Immune-Inflammation Value (PIV) is a novel composite biomarker calculated from complete blood count parameters using the following formula: neutrophil count × platelet count × monocyte count / lymphocyte count. PIV has been proposed as a comprehensive indicator of systemic inflammation.
This cross-sectional observational study aims to investigate the relationship between PISA and PIV in systemically healthy adults.
A total of 160 participants aged 18 years and older will be recruited from the Department of Periodontology, Faculty of Dentistry, Bolu Abant Izzet Baysal University. Participants will be classified as periodontally healthy, gingivitis, or periodontitis according to the 2017 World Workshop Classification of Periodontal and Peri-Implant Diseases and Conditions.
Clinical periodontal parameters, including Plaque Index, Gingival Index, Papillary Bleeding Index, Probing Pocket Depth, Clinical Attachment Loss, Bleeding on Probing, and PISA, will be recorded by a single calibrated examiner.
Complete blood count results obtained within the previous three months will be used to calculate PIV.
The primary objective is to evaluate the association between PISA and PIV. Secondary objectives include assessing the relationships between PIV and other periodontal clinical parameters.
An a priori power analysis performed using G*Power indicated that at least 84 participants were required to detect a moderate correlation (r = 0.30) with 80% power at a significance level of 0.05. To allow subgroup analyses and potential exclusions, 160 participants will be enrolled.
Statistical analyses will be conducted using SPSS software, and statistical significance will be set at p < 0.05.

The record says: finished, as of the sponsor's last update on 5 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation between Periodontal Inflamed Surface Area and Pan-Immune-Inflammation Value (time frame: Baseline (single visit)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2026; AzTrials last refreshed its copy on 6 Nov 2026.
