Quantification of Streptococcus mutans in Different Types of Ligature Wires and Elastomeric Chains

Braz. dent. j; 28 (4), 2017
Abstract This study aimed to test the hypothesis that Streptococcus mutans contamination levels differ according to the type of the orthodontic ligature. Thirteen patients were selected. Each quadrant was randomly subjected to one of the following ligature-use protocols: I) elastomeric chain, II) steel l...

Bacterial translocation and mortality on rat model of intestinal ischemia and obstruction

Acta cir. bras; 32 (8), 2017
Abstract Purpose: To develop an experimental model of intestinal ischemia and obstruction followed by surgical resection of the damaged segment and reestablishment of intestinal transit, looking at bacterial translocation and survival. Methods: After anesthesia, Wistar rats was subject to laparotomy,...

Biosynthesized silver nanoparticles: are they effective antimicrobials?

Mem. Inst. Oswaldo Cruz; 112 (8), 2017
BACKGROUND Silver nanoparticles (AgNPs) are increasingly being used in medical applications. Therefore, cost effective and green methods for generating AgNPs are required.
