This work demonstrated the successful application of N-halamine technology for wound dressings rendered antimicrobial by facile and inexpensive processes. Four N-halamine compounds, which possess different functional groups and chemistry, were synthesized. The N-halamine compounds, which contained oxidative chlorine, the source of antimicrobial activity, were impregnated into or coated onto sta...

Context One of the important goals of root canal therapy is disinfection aided by irrigation and intracanal medicaments. Commonly used nonsteroidal anti-inflammatory agents have shown anti-bacterial activity, thus, when used as intracanal medicaments, nonantibiotic agents have the potential to provide anti-inflammatory, local analgesic, and anti-bacterial activity. Aim The aim of this study i...

OBJECTIVE The aim of this study was to investigate the coronal microleakage of endodontically treated teeth prepared to receive an intracanal post and teeth with an intracanal post but without a prosthetic crown and exposed to contamination by fresh human saliva. MATERIAL AND METHODS A mechanical-chemical preparation following the step-back technique was carried out in 35 extracted single-roo...

Aims: To investigate the physical and antimicrobial properties of low-adherent, silver-containing gelling fibre and certain adhesive foam dressings in vitro. Methods: An in vitro model was used to quantitatively measure fibroblast adhesion to dressings in their dry and hydrated states. Microscopy techniques were used to visualise and quantify aspects of dressing composition and structure. Final...

Instrument fracture within the root canal during root canal treatment is an unwanted and frustrating complication. The fractured segment may hinder cleaning and shaping procedures with potential impact on prognosis of treatment. Fracture of endodontic instrument often results from incorrect use or overuse. If breakage occurs clinically, the patient should be informed of the incident and conside...

OBJECTIVE To seek a consensus on recommendations that would help health professionals choose appropriate wound dressings in daily practice, since a systematic review found only limited evidence to support reported indications for modern wound dressings. PARTICIPANTS A steering committee selected a panel of 27 experts with no declared conflicts of interest from lists of nursing staff and physi...

The aim of this study was to evaluate the antiseptic efficacy of rotary instrumentation associated with calcium hydroxide-based pastes prepared with different vehicles and antiseptics. Chronic periapical lesions were experimentally induced in 72 premolar root canals of four dogs. Under controlled asepsis, after initial microbiological sampling (A1), the root canals were instrumented using the P...

The type of dressing selected for intravascular catheters may influence costs and complications. We carried out a clinical trial to compare the safety and costs of transparent and gauze dressings. We did not find differences in complication rates between transparent (34.1%) and gauze (26.5%) dressings (P = .62). The total cost per patient was $24.82 for transparent and $38.85 for gauze. The res...

BACKGROUND Many patients cannot afford sterile dressings. In St John, New Brunswick, clean dressings have been used instead of sterile dressings for years, with no apparent ill effects. No previous studies have compared the sterility and cost of clean versus sterile dressing materials. OBJECTIVES THE GOALS OF THE PRESENT STUDY WERE TO ANSWER THE FOLLOWING QUESTIONS: how much more sterile are ...
