The purpose of this study was to evaluate the antibacterial efficacy of an intracanal medication composed of calcium hydroxide with 2% chlorhexidine. Dentin from 24 bovine incisors was used. The incisors were made into standardized cylindrical segments of dentin and infected with Enterococcus faecalis. They were then treated with an intracanal paste composed of calcium hydroxide and sterile wat...

AIM The aim of the study was to evaluate the ability of in vitro planktonic and immobilized cell models for determining the antimicrobial efficacy of common antimicrobial wound dressings. METHODS AND RESULTS Five strains of Acinetobacter baumannii, Pseudomonas aeruginosa and methicillin resistant Staphylococcus aureus were tested against four antimicrobial wound dressings containing silver, h...

Objectives: The aim of this study was to determine the feasibility of a portable electrospinning device for the application of wound dressings. Approach: Four polymer nanofibers dressings were applied on superficial partial thickness wounds to a porcine model and compared with a traditional paraffin tulle gras dressing. The polymer nanofibrous dressings were applied using a handheld portable el...

PURPOSE Antimicrobial wound dressings are becoming more popular and are routinely used in the treatment of chronic and problematic wounds. Despite the ever-growing number and types of these antimicrobial products, many practitioners often do not report significant clinical differences between various common antimicrobial wound dressings despite wide variations in cost. Although these dressings ...

Literature review The primary function of calcium hydroxide as a routine intracanal medicament is to provide antimicrobial activity. However, the mechanisms of antimicrobial activity of calcium hydroxide are not well known. Physicochemical properties of this substance may limit its effectiveness in disinfecting the entire root canal system. In addition, calcium hydroxide is not effective agains...

Prevention and treatment of bacterial colonised/infected wounds are critical. Many commercially available silver dressings claim broad-spectrum bactericidal activity over days and are indicated for serious conditions including burns and ulcers. However, there is no peer-reviewed literature available for many newer dressings. This study compared the activity of some of these dressings. Six silve...

OBJECTIVES We are often confused on selecting a suitable wound dressing for the treatment of infected wounds from huge number of available wound dressings. Then, to help clinicians easily select a wound dressing, we compared the antibacterial effects and bacterial retentivity (ie, potency of keeping absorbed bacteria inside wound dressings and preventing them from leaking out) of wound dressing...

Background: Root canal infection and periapical diseases are caused by bacteria and their products. Long term infection may spread bacteria throughout the root canal system. Apical periodontitis caused by infectious microbe that persistent in root canals can cause radiographic and histopathology periapical changes. Chemomechanical preparation and intracanal dressing then are recommended to be c...

This clinical study investigated the effects of endodontic treatment by using different irrigants (limewater + NaOCl and polymyxin B + NaOCl) and intracanal medication on endotoxins in teeth with primary endodontic infection and radiographically visible apical periodontitis. Thirty-three teeth with necrotic pulp and periapical lesions from different patients were selected for this study. Sample...

OBJECTIVES This in-vitro study aimed to compare the push-out bond strength of composite to prepared and unprepared intracanal dentin using a 5th generation bonding agent in primary anterior teeth after etching for seven and 15 seconds. MATERIALS AND METHODS Sixty primary anterior teeth were randomly divided into four groups. In groups one and two, intracanal dentin remained intact while in gr...
