Antimicrobial activity of different disinfectants against cariogenic microorganisms

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to assess the in vitro antimicrobial effects of chlorhexidine digluconate (CHX), polyhexamethylene biguanide (PHBM), and octenidine dihydrochloride (OCT) on cariogenic microorganisms by using their minimum inhibitory concentration (MIC) and minimum bactericidal concentr...

LPS levels in root canals after the use of ozone gas and high frequency electrical pulses

Braz. oral res. (Online); 30 (1), 2016
Abstract The present study aims to verify the effect of ozone gas (OZY® System) and high frequency electric pulse (Endox® System) systems on human root canals previously contaminated with Escherichia colilipopolysaccharide (LPS). Fifty single-rooted teeth had their dental crowns removed and root length...

Clinical effect of photodynamic therapy on primary carious dentin after partial caries removal

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was conducted to assess the clinical effect of photodynamic therapy (PDT) in the decontamination of the deep dentin of deciduous molars submitted to partial removal of carious tissue. After cavity preparation, dentin samples were taken from the pulp wall of nineteen deciduous molars b...

Effect of Resveratrol on periodontal pathogens during experimental periodontitis in rats

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to investigate the antibacterial effect of resveratrol against putative periodontal pathogens during the progression of experimental periodontitis in rats. Periodontitis was induced in rats in one of the first molars chosen to receive a ligature. Animals were assi...

Enamel and dentine demineralization by a combination of starch and sucrose in a biofilm - caries model

Braz. oral res. (Online); 30 (1), 2016
Abstract Sucrose is the most cariogenic dietary carbohydrate and starch is considered non-cariogenic for enamel and moderately cariogenic for dentine. However, the cariogenicity of the combination of starch and sucrose remains unclear. The aim of this study was to evaluate the effect of this combination ...
