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...

BACKGROUND Skin antisepsis is a simple and effective measure to prevent infections. The efficacy of chlorhexidine is actively discussed in the literature on skin antisepsis. However, study outcomes due to chlorhexidine-alcohol combinations are often attributed to chlorhexidine alone. Thus, we sought to review the efficacy of chlorhexidine for skin antisepsis and the extent of a possible misinte...

Alveolar osteitis (AO) is a common phenomenon in the extraction of impacted third molars. As it causes discomfort and affects the patient’s quality of life, it is necessary to reduce the risk of AO. The aim of the present study was to evaluate the efficacy of two CHX gel concentrations on the frequency of AO. The inclusion criteria were being 18-30 years old and having bilateral impacted mandib...

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...

introduction : the aim of this in vitro study was to evaluate the antimicrobial activity of four intracanal medicaments on enterococcus faecalis (e. faecalis). methods and materials: fifty extracted single-rooted human teeth were prepared with standard method. after contaminating the canals with e. faecalis , the samples were divided into one control and four experimental groups ( n =10). the t...
