BACKGROUND To investigate the antifungal activity of propolis, triple antibiotic paste (TAP), 2% chlorhexidine gel and calcium hydroxide with propylene glycol on Candida albicans-infected root canal dentinal tubules at two different depths (200 μm and 400 μm) and two time intervals (day 1 and 7). METHODS A total of 90 extracted human teeth were sectioned below the cementoenamel junction and t...

introduction: alveolar osteitis (ao) is one of the most common postoperative complications after third molar surgery. various techniques have been used to reduce the risk of ao. the aim of the current study was to evaluate the effect of chlorhexidine (chx) bioadhesive gel in preventing the development of ao. methods: patients with bilateral impacted mandibular third molars underwent surgical ex...

Although the introduction of alcohol based products have increased compliance with hand hygiene in intensive care units (ICU), no comparative studies with other products in the same unit and in the same period have been conducted. We performed a two-month-observational prospective study comparing three units in an adult ICU, according to hand hygiene practices (chlorhexidine alone-unit A, both ...

This study compared the effects of carbamide peroxide (CP) and chlorhexidine (CHX) on oral biofilm in vitro. Collagen-coated hydroxyapatite discs were inoculated with subgingival plaque. After 3 weeks, the emergent biofilms were subjected to 1-, 3-, and 10-min exposures of a 1% CHX gel, a 5% CP gel and rinse, and a 10% CP gel and rinse. Subsequently, the biofilms were stained using a two-colour...

OBJECTIVE To investigate the effect of chlorhexidine applications in various forms and concentrations on adhesion and failure modes of metal brackets in vitro. MATERIAL AND METHODS Ninety bovine enamel specimens were allocated to six groups (n=15). Metal brackets were bonded on all specimens after chlorhexidine pre-treatments forming the following groups: (1) untreated specimens (control); (2...

The purpose of this study was to assess the effectiveness of endodontic irrigants in removing the smear layer from instrumented root canal walls using Scanning Electron Microscopy (SEM). The endodontic irrigants used were: 1% sodium hypochlorite (NaOCl); 1% NaOCl mixed to 17% EDTAC; 2% chlorhexidine gel; and Ricinus communis gel. Photomicrographs of the middle and apical thirds were evaluated w...

Aim and objective: The aim objective of this study was to assess the efficacy Calendula officinalis (Linn.) with commercially available chlorhexidine gel tetracycline fibers against plaque bacteria so that it can eventually be incorporated into periodontal anti-infective therapy. Materials method: Plant extract made by 10 grams Preparation plant dried ground leaves were mixed 100ml methanol eth...

This study evaluated the clinical efficacy of 2% chlorhexidine (CHX) gel on intracanal bacteria reduction during root canal instrumentation. The additional antibacterial effect of an intracanal dressing (Ca[OH](2) mixed with 2% CHX gel) was also assessed. Forty-three patients with apical periodontitis were recruited. Four patients with irreversible pulpitis were included as negative controls. T...

To identify topical antimicrobial preparations which may be effective in preventing the transmission of sexually transmitted diseases, we examined the activity of chlorhexidine gluconate (CHG) against Chlamydia trachomatis. Chlamydial elementary bodies were incubated with dilutions of CHG gel for various times from 0 to 120 min. An aliquot of each dilution was further diluted and was inoculated...
