In vitro antioxidant potential of medicinal plant extracts and their activities against oral bacteria based on Brazilian folk medicine.

Background And Objectives: This study aims to determine antibacterial activities of Cocos nucifera (husk fiber), Ziziphus joazeiro (inner bark), Caesalpinia pyramidalis (leaves), aqueous extracts and Aristolochia cymbifera (rhizomes) alcoholic extract against Prevotella intermedia, Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus mutans and Lactobacillus casei. The antioxidant activity and acute toxicity of these extracts were also evaluated.

Material And Methods: The plant extracts antibacterial activity was evaluated in vitro and the minimal inhibitory concentration (MIC) was determined by the broth micro-dilution assay.

Treatment protocol to control Streptococcus mutans level in an orthodontic patient with high caries risk.

The purpose of this article is to report a protocol for treating an orthodontic patient with a high risk of developing caries. The salivary level of Streptococcus mutans was evaluated during various stages of orthodontic treatment. It was significantly high before professional application of 1% chlorhexidine collagen gel, daily mouth rinsing with 0.

An ectophosphatase activity in Candida parapsilosis influences the interaction of fungi with epithelial cells.

This study describes the biochemical characterization of a phosphatase activity present on the cell surface of Candida parapsilosis, a common cause of candidemia. Intact yeasts hydrolyzed p-nitrophenylphosphate to p-nitrophenol at a rate of 24.30+/-2.
