Brief summary

the study is about using healthy bacteria to improve the overall gingival and overall health and prevent or decrease the bad odor of the mouth caused by bad bacteria

Detailed description

The goal of this study is to verify the effect of Probiotics on oral Health Status and eliminate the gingival disease and Halitosis by measuring the levels of salivary biomarkers (cytokine IL-1b and proteases Matrix metalloproteinase (MMP-8) in saliva) and level of volatile sulfur compounds (VSCs) and their effects on improving gingival diseases clinical parameters in person age of (17-25) years old. The participants are randomly divided into two parallel groups (A, B). Group A will take probiotics and group B will take placebo for 28 days. The levels of IL-1b, MMP-8 in saliva, and VSCs measurement will be recorded respectively in different intervals of zero time and repeated on 14 days and 28 days. Statistical analysis will be done then comparative between two groups
