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...

OBJECTIVE: To investigate the efficacy of intrapartum vaginal flushings with chlorhexidine compared with ampicillin in preventing group B streptococcus transmission to neonates. METHODS: This was a randomized controlled study, including singleton pregnancies delivering vaginally. Rupture of membranes, when present, must not have occurred more than 6 h previously. Women with any gestational comp...

A major drawback to clinicians prescribing and patients using chlorhexidine rinse is the development of extrinsic staining. In order to assess the effectiveness of a whitening dentifrice in controlling chlorhexidine stain, fifty-seven subjects rinsed with chlorhexidine twice daily while brushing twice daily with either fluoridated whitening or a fluoridated regular dentifrice. Stain was assesse...

Despite continued advances in preoperative preventive measures and aseptic technique, surgical site infections remain a problem. The purpose of this study was to evaluate the time-dependent effectiveness of chlorhexidine, a common surgical preparation solution, at various concentrations. Agar plates containing a Mueller-Hinton medium were inoculated with Staphylococcus aureus (lux) bacteria. Th...

The fi rst and main goal of root canal treatment is the elimination of microorganisms from the contaminated root canal system and providing an environment for the healing of periapical tissues. Instrumentation alone cannoteffectivelyclean the complex root canal system. Souse of irrigantsalong mechanicalpreparationis required. But no single solution is able to fulfi ll these actions completely. ...

To the Editor—We read with great interest the article ‘‘Guidelines for the Prevention of Intravascular Catheter-related Infections’’ in the May 2011 issue [1]. We commend the authors for their excellent extensive review of the literature and subsequent guidelines. These guidelines, however, recommend the use of ‘‘.0.5% chlorhexidine preparation with alcohol for skin antisepsis during CVC insert...

OBJECTIVES Oil pulling is an age-old practice that has gained modern popularity in promoting oral and systemic health. The scientific verification for this practice is insufficient. Thus, this study evaluated the effect of coconut oil pulling on the count of Streptococcus mutans in saliva and to compare its efficacy with that of Chlorhexidine mouthwash: in vivo. The null hypothesis was that coc...

PURPOSE 1) To evaluate the effects on the conjunctival flora of gentamicin ophthalmic eye drops 0.3%, given four times in 45 minutes, and a conjunctival rinse with 10 ml chlorhexidine 0.05% solution. 2) To investigate retrospectively the rate of endophthalmitis after cataract operations when these antimicrobials were applied preoperatively. METHODS Seventy-six patients undergoing standard pha...

AIM Recent advances including the incorporation of antibacterial substances, such as chlorhexidine, into restorative materials such as glass ionoer cement (GIC), might alter the physical properties of the material, which might affect the marginal seal of the restorations. Hence, the objective of this study was to compare the marginal sealing ability of GC Fuji IX modified with 1% chlorhexidine ...

* Correspondence: [email protected] Protothecosis is an infection reported in humans and in many other animal species caused by achlorophyllous algae of the genus Prototheca. These algae are primitive unicellular organisms considered to be chlorophylllacking mutants that have adopted a heterotrophic mode of nutrition. These organisms are widely disseminated in different environments...
