Changes in the bacterial flora composition and count in the saliva and tongue coating
The change in oral microflora at the genus level for each sampling time of saliva and tongue coating samples is shown as a bar chart in Figure Changes in oral microflora at each sampling time. Levels of bacterial genus with an occupancy of 1% or more are shown, and those of less than 1% are described as “other.” (a) saliva/CPC spray group. (b) Saliva/control group. (c) Tongue/CPC spray group. (d) Tongue/control group. LEfSe analysis was performed 3 weeks after the intervention with CPC spray. (e) Saliva/3 weeks and (f) tongue/3 weeks, the CPC spray group is shown in red and the control group is shown in green. CPC, cetylpyridinium chloride; LDA, linear discriminant analysis; LEfSe, LDA effect size.Changes in the total bacterial count in the saliva and tongue coating samples are shown in Figure
