Chitosan is a well sought-after polysaccharide in biomedical applications due to its biocompatibility, biodegradability to non-toxic substances, and ease of fabrication into various configurations. However, alterations in the anti-bacterial properties of chitosan in various forms is not completely understood. The objective of this study was to evaluate the anti-bacterial properties of chitosan ...

This study evaluated the role of periodontal pathogens in 50 hospitalized patients with hospital acquired pneumonia compared with 30 healthy controls. Specimens of oropharyngeal aspirate, dental plaque bronchoalveolar lavage and blood cultured 1 or more pathogens in around 80% of patients, predominatel Staphylococcus aureus, followed by coagulase-negative staphylococci, Streptococcus pneumonia...

Background: Cyanoacrylate tissue adhesives have been used as a substitute to silk for intraoral wound closure. Placement of sutures provides a corridor for accumulation of microorganisms into tissue which leads to infection. Cyanoacrylate-based adhesives exhibit many properties of an ideal wound closure agent, minimizing the problems generated by suturing thread. The antimicrobial properties of...

background: oral care plays an inevitable role in health and well-being of patients in intensive care units (icus). poor oral care causes colonization of respiratory pathogens and secondary respiratory infections. ventilator-associated pneumonia occurs in patients on mechanical ventilation for more than 48 hours. it results in prolonged duration of mechanical ventilation, mortality and health e...

Oral suction devices may be fomites for nosocomial infections. This study was designed to evaluate the rate of contamination of Yankauer suction catheters. Among the 20 catheters tested, 16 (80%) yielded cultures for pathogens. Seven (35%) were colonized with multiple pathogens. Among the organisms encountered included methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant ...

Periodontal pathogens have been linked with increased risk of systemic illness and complications in existing disease. Recently, several articles detailing these findings have been published, emphasizing the importance of the association between periodontitis and systemic health problems. In fact, a recent meta-analysis reports that oral infections have been shown to be associated statistically ...

Biofilm Repellent Commensals In article number 2101410, Muhammad Imran Rahim and co-workers report a novel coating of commensal microflora on biomaterial surfaces that can prevent the colonization infectious biofilm-forming oral pathogens. This remains biocompatible with human cells, suggesting an advanced therapeutic approach to control difficult-to-treat biomaterial-related infections in cavi...

A novel antimicrobial peptide, GAPI, has been developed recently by grafting gallic acid (GA) to polyphemusin I (PI). The objective of this study was investigate the antibacterial effects GAPI on common oral pathogens. This laboratory used minimum inhibitory concentrations and bactericidal assess properties against Transmission electron microscopy examine bacterial morphology both before after ...

Background and Purpose: Herbal toothpastes are more secure and efficacious and less poisonous due to containing natural chemicals as compared with the synthetic toothpastes. The present study aimed to formulate a polyherbal toothpaste using accessible medicinal plants in Iran and evaluate its efficiency in the protection of oral hygiene and prevention of dental caries. Materials and Methods:...

We used molecular epidemiologic techniques to document patient-to-patient transmission of hepatitis B virus (HBV) between 2 outpatient oral surgery patients operated on 161 min apart. Serological testing of 25 (93%) of 27 patients operated on after the source patient revealed that 19 (76%) of 25 were previously immune to HBV; no additional cases were identified. We found no deficiencies in infe...
