The Effect of Periodontal Treatment on Psoriasis

Study Overview
=================
Brief Summary
-----------------
There is a relationship between psoriasis and periodontal disease. This relationship may be double-sided.

Detailed Description
-----------------
The aim of this randomized controlled clinical study was to determine the effect of non-surgical mechanical periodontal treatment on psoriasis. The study population consisted of 92 periodontitis patients with psoriasis who had untreated periodontal disease. Two randomized groups were formed from these patients. Immediate periodontal treatment (test group, n = 46) and delayed periodontal treatment (control group, n = 46). Clinical periodontal measures, saliva interleukin 2, interleukin 6 and secretory immunoglobulin A levels and PASI scores were performed at baseline and 8th week in control and test group.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Test Group<br>Psoriatic measurements and saliva samples were taken from periodontal disease patients before treatment and after 8 weeks. Intervention: Non-surgical periodontal treatment was performed and the Psoriasis Area and Severity Index (PASI) was filled, saliva samples were taken. | Other: Psoriatic measurements<br>* Psoriasis Area and Severity Index (PASI) was performed baseline and after 8 weeks. Saliva samples were taken from patients for the evaluation of proinflammatory cytokine baseline and after 8 weeks.<br>Other: Non-surgical periodontal treatment<br>* Non-surgical periodontal treatment was performed baseline and after 8 weeks. Saliva samples were taken from patients for the evaluation of proinflammatory cytokine baseline and after 8 weeks.<br>Other: saliva samples<br>* Saliva samples were taken from patients for the evaluation of proinflammatory cytokine baseline and after 8 weeks.<br>|
| Placebo Comparator: Control Group<br>Psoriatic measurements and saliva samples were taken from periodontal disease patients at the baseline and after 8 weeks without the periodontal treatment. Intervention: Psoriasis Area and Severity Index (PASI) was filled, saliva samples were taken. | Other: Psoriatic measurements<br>* Psoriasis Area and Severity Index (PASI) was performed baseline and after 8 weeks. Saliva samples were taken from patients for the evaluation of proinflammatory cytokine baseline and after 8 weeks.<br>Other: saliva samples<br>* Saliva samples were taken from patients for the evaluation of proinflammatory cytokine baseline and after 8 weeks.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proinflammatory cytokines | The changes in proinflammatory cytokines levels within 8 weeks. Higher values represent a worse outcome. The decrease in proinflammatory cytokines levels is expected after periodontal treatment. | Baseline and after 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gingival index | The changes in gingival index level after periodontal treatment. Gingival index was measured for determining the severity of disease and clinical outcome. Higher values represent a worse outcome. After periodontal treatment, a reduction in gingival index value is expected. | Baseline and after 8 weeks | 
| PASI index | The changes in PASI index level after periodontal treatment. PASI index was measured for determining the severity of psoriasis disease. Higher values represent a worse outcome. After periodontal treatment, a reduction in PASI index value is expected. | Baseline and after 8 weeks |
