The four indexes including plaque index (PI), gingival index (GI) [In this study, at baseline (Day 0), forty-two potential patients were examined by a single clinician. Indeed, at the beginning (Day 0), clinical parameters of gingivitis were measured by a single calibrated clinician who was blinded to group assignment. In both groups, the mean score of all BOP, GI, PI, and OHI-s parameters were measured and compared over time to investigate the effects of probiotic 
Gingival index (GI).One of the significant indexes influential in the condition of the gums is the gingival index, which has four levels. Each tooth is divided into four levels, and each one is given 3 points according to the table. If the total score of each level is being divided by four, a gingival index is obtained. The diagnostic criteria for GI employed in this study are described by Loe & Silness (1963) (Table 
Plaque index (PI).The diagnostic criteria used for the PI, based on Loe & Silness (1963), are given in Table 
Presence/absence of bleeding on probing (BOP).Bleeding gums is caused by probe stimulation, indicating the progression of the disease. BOP was assessed upon probing at four sites (mesio-buccal, mid-buccal, disto-buccal, and mid-lingua) and sorted according to the description by Mühlemann (1977) (Table 
Oral hygiene index (OHI-s).An index for measuring oral health as demonstrated according to the assortment in Table
