With the increase in the incidence of diabetes and obesity, among other artificial sweeteners the need of natural non-caloric sweetener with acceptable taste and without any adverse effects is demanding.So,the use of stevia presents beneficial effects to general and oral health and its properties could result potentially effective in the treatment of periodontal diseases.

Stevia is considered as a novel molecule, because it is 100% natural and non caloric sweetener, with more sweetness than sucrose, without any adverse effects. It also demonstrates multiple benefits like anti-plaque effect, anti-diabetic effect, anti-periodontophatics properties, anti-hypertensive properties, anti-cariogenic properties etc. There are many studies conducted on stevia in humans, which justifies my study.
