About this study

Official title: Effect of Non-surgical Periodontal Therapy in Hypertensive Patients With Assessment of Endocan and TNF-a Levels in Gingival Crevicular Fluid (Case Control Study)

There is a strong crossway relationship between periodontitis and hypertension. Hypertension is the most prevalent of cardiovascular diseases and its prevalence is increased by the presence of periodontitis. Periodontal attachment loss is higher in hypertension patients when compared to healthy subjects. Both are examples of non-communicable diseases (NCDs), also known as chronic inflammatory diseases, they tend to be of long duration and are the result of a combination of genetic, physiological and environmental factors. The lack of an appropriate balance between these factors results in cellular changes as well as the levels of cytokines with subsequent changes in clinical manifestations of periodontal diseases. Both periodontitis and hypertension are associated with inflammation and an increase in specific proinflammatory cytokines.

Aim of the study: To investigate the correlation between the clinical parameters and the levels of Endocan and TNF-α in gingival crevicular fluid (GCF) before and after non-surgical periodontal therapy (NSPT) in stage II periodontitis patients with hypertension in comparison to non-hypertensive patients.

Read the detailed description

Clinical assessment of specific clinical parameters: plaque index, gingival index, probing depth, clinical attachment level (CAL) as primary outcome. Biochemical assessment of Endocan and TNF-α levels in GCF by Enzyme Linked Immunosorbent Assay (ELISA) as well as measurement of blood pressure at baseline and after 3 months as secondary outcomes.

Study procedures:

Details of the interventions, testing and follow up:

Group Case (I):

This group will include 20 patients diagnosed with stage II periodontitis and controlled hypertension. They will receive NSPT and oral hygiene measures will be instructed following treatment.

Group Control (II):

This group will include 20 patients diagnosed with stage II periodontitis and no hypertension. They will receive NSPT and oral hygiene measures will be instructed following treatment.

Study protocol and surgical steps:

Before enrollment, a detailed case history will be recorded. A calibrated standard aneroid sphygmomanometer. The average of 3 blood pressure values (systolic blood pressure SBP and diastolic blood pressure DBP), will be taken at 1 minute interval, this will be used in data analyses.

For all patients who are suitable for the study the following clinical evaluation parameters will be measured:

Plaque index (PI) Gingival index (GI) Probing depth (PD) Bleeding on probing (BOP) Clinical attachment level (CAL) Standardized periapical radiograph.

Note: Full mouth assessment will be done and then the deepest site will be evaluated for the GCF sample.

Baseline GCF samples will be taken the day after patients were clinically evaluated to prevent contamination with blood related to the probing of inflamed areas.

The sample areas will be insulated with cotton rolls to prevent saliva contamination and all supragingival plaque will be eliminated. The paper strips will be placed into the periodontal pocket and then permitted to remain for 30 seconds.

All patients will undergo full mouth NSPT, this will be done using ultrasonic and hand instruments.

The patients will receive oral hygiene instructions including tooth brushing using modified bass technique. All patients will be provided with toothbrush (soft), toothpaste (signal) and interdental cleaning with dental floss or interdental brush.

Two weeks follow-up to ensure that appropriate oral hygiene instructions are followed. The clinical parameter to be assessed will be PI and BOP, patients with PI 2 and BOP > 10% will be eliminated from the study.

Then clinical evaluation, collection of samples and measuring of SBP and DBP will be performed at 3 months after NSPT in both groups.

The Outcomes Assessment:

Clinical assessment. Biochemical assessment. Blood pressure measurement.

For clinical assessment the following clinical parameters including PI, GI, PD, BOP and CAL will be recorded for each individual at 1 site at baseline and 3 months postoperatively. Clinical parameters of PI and BOP will be assessed at 2 weeks, 4 weeks and 6 weeks follow ups to ensure proper oral hygiene. Regarding biochemical analysis, GCF samples will be collected preoperative and 3 months after NSPT. Blood pressure measurements will be taken before and after 3 months of NSPT.

Clinical Assessment The following clinical parameters will be taken using UNC15 Probe at baseline and 3 months postoperative.

Plaque index:

  • no plaque.
  • plaque recognized only by running a probe across the tooth surface.
  • plaque visible to the naked eye.
  • abundance of soft matter.

Gingival index:

  • Normal gingiva
  • Mild inflammation - slight edema. No bleeding on probing
  • Moderate inflammation -redness, edema and glazing. Bleeding on probing.
  • Severe inflammation - marked redness and edema. Ulceration. Tendency for spontaneous bleeding

Probing depth :

Will be measured from the gingival margin to the depth of the pocket at four points (mesio-facial, mid-facial, disto-facial and mid-lingual) to the nearest millimeter using UNC-15 periodontal probe. The average of the three facial points will be recorded as the facial probing depth (FPD) while the mid-lingual point will be recorded as the lingual probing depth.

Clinical attachment level (CAL):Will be measured from the CEJ to the depth of the periodontal pocket.

  1. Biochemical Assessment:

Biochemical assessment will be done at the deepest pocket at baseline and 3 months after non-surgical periodontal therapy. Endocan and TNF-α levels will be determined using commercial human Endocan (ESM-1) and TNF-α ELISA Kits. Measurements will be performed according to the manufacturer's instructions.

  1. Blood Pressure measurement: Systolic and diastolic Blood pressure measurement will be done according to, 2020 International Society of Hypertension Global Hypertension Practice Guidelines.

IX. Statistical Analysis The obtained results will be collected, tabulated, and subjected to appropriate statistical analysis.
