An observational study in Psoriasis and Periodontal Diseases, sponsored by Kahramanmaras Sutcu Imam University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-05-10.
Sponsored by Kahramanmaras Sutcu Imam University · Observational
This study aimed to compare the levels of IL-17 (interleukin- 17), Bcl-3 (B-cell lymphoma 3-encoded protein), and IκBζ (NF-kappa-B inhibitor zeta) in the gingival crevicular fluid of psoriatic and healthy individuals and the clinical parameters such as periodontal health, gingival index, plaque index and mobility (using periotest device)in the patient and control groups.
Patient selection
Ten patients previously diagnosed with psoriasis who visited the Van 100. Yıl University Faculty of Dentistry Oral and Maxillofacial Radiology dental clinic were included in the study. Non-psoriasis individuals were selected from volunteer patients attending the same dental clinic.
Clinical measurements
A periodontist conducted the periodontal evaluation, which included a comprehensive assessment of clinical periodontal status, a full mouth manual periodontal charting, measurement of probing depth, clinical attachment level, bleeding on probing, and evaluation of mobility using a periotest device. Additionally, information regarding the patient's smoking status, frequency of smoking, and oral hygiene habits was obtained.
Gingival crevicular fluid (GCF) collection
Samples were taken from two mandibular molar teeth. Before sampling, the sites were isolated with cotton rolls and then carefully dried with an air syringe to avoid saliva contamination. GCF was collected using sterile periodontal strips by gently inserting them into the gingival sulcus or pocket until slight resistance was noticed. After 30 s, the strips were collected into sterile tubes and immediately transported to the laboratory for storage (-40 °C) and posterior analysis.
1,928 studies on the registry are indexed under Psoriasis; 234 are open to participants now.
This study's enrollment of 12 is below the median of 200 across 400 observational studies indexed under Psoriasis.

Level of Gene expression
In the real-time polymerase chain reaction (PCR) results of the β-actin gene, which was used as a housekeeping gene in the study, the automatic threshold value was determined by the device as 0.02. It was observed that all samples were above the threshold value and gave a ct value. According to the housekeeping gene, IL-17, IκBζ, and Bcl-3gene expression values were determined.
Time frame: Sample collection during examination, approximately 2 months
Plaque index
To determine the plaque index of the patients, their dental plaque thickness was evaluated by probing surfaces of selected teeth using a periodontal probe. Scores range from 0 to 3.
Time frame: Baseline, week 2
Gingival index
To determine the gingival index of the patients, gingival bleeding caused by running a Williams periodontal probe inside the pocket on the mesial, distal, buccal, and palatal surfaces of selected teeth was evaluated. Scores range from 0 to 3.
Time frame: Baseline, week 2
Clinical attachment level
This parameter represents the extent of periodontal support that has been lost around a tooth and is measured with the periodontal probe as the distance from the cemento-enamel junction (CEJ) to the base of the pocket (in mm)
Time frame: Baseline, week 2
Tooth Mobility
The amount of tooth mobility can be displayed by a value called periotest value (PTV) ranging from -8 to +50
Time frame: Baseline, week 2
Plan to share: No
