Randomly in all subjects one quadrant will be allotted as test site for placing stevia gel in the gingival sulcus having probing depth ≥ 5mm after performing thorough scaling and root planing.

Other quadrant will be allotted as a control site for placing placebo in the gingival sulcus having PD≥ 5mm after performing thorough scaling and root planing.

Periodontitis

Stevia has an anti-plaque effect because of its ability in decreasing the formation of bacterial insoluble polymers.It significantly decreases the production of TNF-R and IL-1a and slightly decreases the production of NO in stimulated cells with LPS and THP-1 showing its anti-inflammatory properties.These characteristics in combination with anti-diabetic properties could results in the effective treatment of periodontal diseases.

Efficacy of Stevia Rebaudiana Bertoni on Levels of GCF Glucose and Bio-markers in Diabetic Patients With Periodontitis-A Split Mouth Randomized Controlled Trial.

GCF samples can be eluted from the strips by placing them in Eppendrof® tubes that contained 500 micro-litre of buffer and will be stored at -80℃ until analysis was done. The levels of GCF Ghrelin will be evaluated by using commercially available ELISA kit.

Probing depth (PD): Distance from the gingival margin to the bottom of gingival sulcus in mm.

Test whether preloads of tea and crackers with cream cheese sweetened with Stevia lover postprandial insulin levels compared to preloads of tea and crackers with cream cheese sweetened with Sucrose or Aspartame by measuring blood insulin and glucose levels immediately prior to the lunch preload,immediately before lunch test meal, and at thirty minutes, one hour, and two hours after the lunch test meal.

Test whether preloads of tea and crackers with cream cheese sweetened with Stevia have different hedonic ratings compared to preloads of tea and crackers with cream cheese sweetened with Sucrose or Aspartame by examining hunger and satiety ratings after the preload.
