background : this study investigated the in vitro and in vivo antibacterial effects of three mouthwashes on su-pragingival plaque microbiota. the three mouthwashes under study were 0.2% chlorhexidine (chx), listerine®, and persica (pm). water was used as negative control. methods : supragingival plaque samples were collected from 32 patients with gingivitis in the dental school of shahid behesh...

background and objectives: recently, use of herbal medicine and plant extracts as a substitute for commercially available chemical drugs for control of infectious diseases such as dental caries and periodontal disease has become increasingly popular. the present study was aimed to evaluate the effect of rhus coriaria l. water extract on five common oral bacteria and bacterial biofilm formation ...

Supragingival plaque is permanently in contact with saliva. However, the extent to which the microbiota contributes to the salivary bacterial population remains unclear. We compared the compositional shift in the salivary bacterial population with that in supragingival plaque following periodontal therapy. Samples were collected from 19 patients with periodontitis before and after periodontal t...

Introduction: One of the most common problems we confront in orthodontic therapy is periodontal diseases. Initial factor which causes these diseases is colonization of anaerobic microorganisms in subgingival plaque. Technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque. However, it seems necessary to assess va...
