Introduction: Debridement of root canal using appropriately safe and effective irrigants is the key factor for long-term success. Purpose of this study was to compare the antibacterial effect of propolis with 5.25% sodium hypochlorite, and 2% chlorhexidine against enterococcus faecalis. Materials &Methods: In this study, 36 single-canal roots were used. The crown was removed and instrumentat...

Background and Aim: This study was designed to explore the clinical utility of apricot kernel decoction on salivary glycoproteins in patients with periodontitis. Methods: The samples were obtained from 123 subjects divided into 4 groups, namely healthy individuals (healthy), non-treated periodontitis (control), chlorhexidine-treated (chlorhexidine) both (decoction + chlorhexidine). Salivary sia...

BACKGROUND In infected periapical tissues, Enterococcus faecalis is one of the most common dominant bacteria. Chlorhexidine has been proved to show strong antibacterial ability against E. faecalis but is ineffective in promoting mineralization for tissues around root apex. Mesoporous calcium-silicate nanoparticles are newly synthesized biomaterials with excellent ability to promote mineralizati...

The chlorhexidine resistance of 317 strains of Pseudomonas aeruginosa isolated from hospital patients was determined. The distribution pattern of their susceptibility to chlorhexidine clearly revealed two peaks, and the frequency of resistance to chlorhexidine was 84.2%.

The purpose of this study was to compare the reaction of rat subcutaneous connective tissue to 0.9% sterile saline, 2.5% sodium hypochlorite (NaOCl), 5.25% NaOCl and 2% chlorhexidine gluconate solution or gel. Six circles were demarcated on the dorsal skin of 24 male Wistar rats, leaving 2 cm between each circle. Using a syringe, 0.1 mL of each root canal irrigant was injected subcutaneously in...

Recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. End-product reutilization, low product concentration, large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2, 3-butanediol production. Extraction can ...

PURPOSE To determine the bactericidal efficacy of a new topical antiseptic for preoperative skin preparation, olanexidine gluconate (development code: OPB-2045G), against transient or resident bacterial flora on the skin of cynomolgus monkeys. METHODOLOGY After measuring baseline bacterial counts on test sites marked on the abdomens, we applied olanexidine, chlorhexidine or povidone-iodine. A...

OBJECTIVE To evaluate the effect of vaginal disinfection with chlorhexidine gel during labor on vertical transmission of group B streptococcus, as a method to prevent vertical transmission and subsequent neonatal early onset group B streptococcal disease. STUDY DESIGN A prospective study with randomization of 1020 parturients to one of three groups as soon as labor started. In all parturients...

Objectives The main objective is to evaluate the efficiency in removal of smear layer of mixture of tetracycline, acid and detergent (MTAD), sodium hypochlorite (NaOCl), ethylenediaminetetraacetic acid (EDTA) and chlorhexidine gluconate by scanning electron microscope (SEM) evaluation and also to evaluate the antimicrobial action of the same irrigants against standard culture strains of Enteroc...

Comparison of the healing of immediate function implants. Inside maintenance protocol using Hyaluronic Acid and Chlorhexidine gels Nobre et al Dept of Oral Hygiene, Lisbon Journal of Clinical Periodontology Results The results demonstrate the importance of a maintenance protocol in immediate function implants. These findings show that using Gengigel for the first two months post implant (healin...
