Abstract (sommario):
This thesis examines the factors affecting the stability of chlorhexidine salts (principally gluconate) in dilute aqueous solution (0.001 to O.05%w/v). Such studies are pertinent to the use of chlorhexidine as a preservative in aqueous pharmaceutical products. The introduction details the factors affecting the stability of pharmaceuticals in solution. Published work on the physico-chemical properties of chlorhexidine and structurally related compounds is then reviewed together with methods available for the quantitative analysis of chlorhexidine. The experimental section describes the evaluati

Abstract (sommario):
Dental implants are a popular solution to missing teeth; they are predominantly formed from titanium due to its biocompatibility, corrosion resistance and high rate of osseointegration. While micro-roughening of the surfaces has been shown to increase osteoblast adhesion and proliferation, it has also been shown to increase the adhesion of bacteria and therefore the likelihood of implant infection and implant failure. Chlorhexidine is a broad spectrum antimicrobial agent used extensively in healthcare, particularly in oral care products such as mouthwash. It has previously been shown to adhere

Abstract (sommario):
Surgical site infections (SSI) are a prevalent health care-associated infection (HAl). Prior to the mid-19th century, surgical sites commonly developed postoperative wound complications. It was in the 1860's, after Joseph Lister introduced carbolic acid and the principles of antisepsis that postoperative wound infection significantly decreased. Today, patient preoperative skin preparation with an antiseptic agent prior to surgery is a standard of practice. Povidone-iodine and chlorhexidine gluconate are currently the most commonly used antimicrobial agents used to prep the patient's skin. In t

Abstract (sommario):
Effective skin antisepsis prior to incision of the skin, for example, during surgery, is essential in preventing subsequent infection. However, infections associated with invasive procedures remain a significant cause of morbidity and mortality and impose additional costs upon the Health Service. Current evidence-based guidelines recommend that 2% (w/v) chlorhexidme digluconate (CHG), preferably in 70% (v/v) isopropyl alcohol (IPA), is used for skin antisepsis prior to incision of the skin. However, many antiseptics poorly permeate the skin and microorganisms residing in the deeper layers and

In response to improving quality patient care, combined with the growing rates of surgical site infections (SSIs) in vascular patients, the need to explore current practice trends with current evidence has been identified. SSIs affect quality patient care and compromise patient safety. Empirical evidence has recommended the use of a chlorhexidine wash preoperatively to reduce SSIs. Despite this recommended practice, vascular patients were not receiving it in their routine plan of care within a hospital organization in southern Ontario.

Staphylococcus epidermidis are common Gram-positive bacteria and are responsible for a number of life-threatening nosocomial infections. Treatment of S. epidermidis infection is problematic because the organism is usually resistant to many antibiotics.

The aims of this thesis were to investigate and evaluate the susceptibility of isolates of S. epidermidis from various infections to chlorhexidine (CHX) and to other disinfectants such as benzalkonium chloride (BKC), triclosan (TLN) and po

Abstract (sommario):
<p>Dental plaque is the most important etiological factor of periodontal diseases. Mechanical plaque control is the most effective way in preventing periodontal diseases. Chemical plaque control methods (such as mouthrinses) have been recommended to be used because of some drawbacks in the mechanical methods in some areas of the dentition (such as interproximal areas). But are these mouthrinses really effective in those areas? The aim of this study was to compare the effectiveness of Essential Oils mouthrinse (Listerine) on plaque formation in interproximal areas with Chlorhexidine and Sterile

Abstract (sommario):
Background: Gingivitis, which is an inflammatory response of the gingival tissues to bacterial plaque, can be treated by brushing and flossing or using chlorhexidine (CHX). Objective: To determine whether floss presoaked in CHX would improve oral health relative to floss presoaked in placebo solution. Materials and methods: A 3 month, double-blinded, parallel, randomized control trial was conducted on 27 adults with a minimum of 10 bleeding sites, who were randomly assigned to dental floss with 0.12% CHX or a placebo solution (QS). Scaling, rubber cup prophylaxis, and flossing instructi

Abstract (sommario):
<p> It is often observed that the slimy matrixes of various bacterial-formed biofilms can limit their disinfection. This investigation demonstrated that disinfection effectiveness by either photodynamic therapy (PDT) or chlorhexidine irrigation is significantly improved by collapse of that matrix using the non-bactericidal reagent delmopinol as part of the treatment sequence. Cyclic shear-producing conditions were used to grow 4-day, whole salivary and growth media biofilms on glow-discharge-treated polystyrene (N=46) and mini-germanium internal reflection prisms to serve in a periodontal cryp

Abstract (sommario):
In the field of Paediatric Dentistry, brushite cement has potential as an endodontic medicament and bone substitute material. Clinical applications however are limited due to their inherent properties, such as rapid setting time and poor mechanical properties. Antimicrobial e.g. chlorhexidine (CHX) could be incorporated into the cement for localised drug release. Aim and objectives: The aim of this study was to assess if partial replacement of citric acid (CA) by polyacrylic acid (PAA) can improve the properties of conventional brushite cements. The objectives were to assess the effects of var
