Antimicrobial susceptibility and composition of microcosm dental plaques supplemented with sucrose.
The aims of this study were to evaluate the effects of repeated chlorhexidine gluconate (CHG) pulsing on the viability and bacterial composition of microcosm dental plaques derived from human saliva. The biofilms were grown on bovine enamel discs in a constant-depth film fermentor fed with an artificial saliva which was supplemented thrice daily with sucrose. The microcosm plaques had total via...
متن کاملResponse of single species biofilms and microcosm dental plaques to pulsing with chlorhexidine.
The aim of this study was to determine the effect of pulsing chlorhexidine gluconate, at concentrations commonly used in mouthwashes, on Streptococcus sanguis biofilms and microcosm dental plaques in vitro. Biofilms were grown on bovine enamel and nutrients were supplied in the form of artificial saliva. Pulsing experiments were carried out on steady-state biofilms using 0.05 or 0.2% chlorhexid...
متن کاملStructural studies of microcosm dental plaques grown under different nutritional conditions.
The aim of this study was to investigate the structure of intact oral biofilms using confocal laser scanning microscopy (CLSM). Mixed-species biofilms were grown on enamel discs in a constant depth film fermentor. The biofilms were fed with a mucin-containing artificial saliva with or without sucrose supplementation. Biofilms were examined using a Wild-Leitz CLSM, operating in reflected light m...
متن کاملLethal photosensitization of bacteria with 8-methoxypsoralen to long wave length ultraviolet radiation.
Severe, or even lethal, cellular damage can follow the conjoint action of a chemical photosensitizer and effective frequencies of the electromagnetic spectrum. The fact that bacteria, as well as other cellular systems, are subject to photosensitization by such compounds as methylene blue was known fifty years ago (Reitz, 1908). The relatively limited number of studies of bacterial photosensitiz...
متن کاملnandrolone plus moderate exercise increases the susceptibility to lethal arrhythmias
conclusions the findings suggest that chronic coadministration of nandrolone with moderate-intensity endurance exercise facilitates the vf occurrence in rat. complementary studies are needed to elucidate the involved mechanisms of this abnormality. results nandrolone, exercise, and their combination were associated with heart hypertrophy. exercise could prevent the incremental effect of nandrol...
