About 70% of all people with severe burns die from related infections, despite advances in treatment regimens and the best efforts of nurses and doctors. Although silver-eluting wound dressings are available for addressing this problem, there is growing evidence of the deleterious effects of such dressings in delaying the healing process owing to cellular toxicity. A new concept of antibiotic-e...

BACKGROUND Antimicrobial silver dressings are used beneath graduated compression in the treatment of venous ulceration. There is little information on whether their use is effective. This was a prospective randomized trial and cost-effectiveness analysis of silver-donating versus non-silver low-adherence dressings in the treatment of venous leg ulcers. METHODS Patients were randomized between...

The purpose of this study was to investigate the antibacterial activity of calcium hydroxide [Ca(OH)2] combined with chitosan solutions against Enterococcus faecalis-infected root canal dentin and the effect of this new intracanal medicament on the bond strength of RealSeal sealer to radicular dentin. An experimental intracanal medicament was prepared by mixing different concentrations of chito...

Chemical auxiliary substances (CAS) are essential for a successful disinfection and cleanness of the root canals, being used during the instrumentation and if necessary, as antimicrobial intracanal medicaments. Different CAS have been proposed and used, among which sodium hypochlorite (NaOCl), chlorhexidine (CHX), 17% EDTA, citric acid, MTAD and 37% phosphoric acid solution. CHX has been used i...

The aim of this study was to compare the analgesic effects of Calcium hydroxide and Chlorhexidine as intracanal medicaments in three different groups of patients. This interventional study was conducted over a period of one year at the Department of Operative Dentistry, Fatima Jinnah Dental Hospital, Karachi. 465 single rooted teeth of patients were divided into three equal groups with 155 teet...

INTRODUCTION This study evaluated and compared colony forming units (CFUs) and minimum inhibitory concentrations (MICs) of calcium hydroxide and propolis as intracanal medicaments. MATERIALS AND METHODS Eighty human single-root and caries-free teeth were selected and divided into five groups. Crowns were removed. Root canals were then prepared in a step-back manner. The samples were then inoc...

Use of new keratin-based wound dressings represent a novel approach to wound management. The authors present three patients with recalcitrant, venous and mixed venous, and arterial leg ulcers treated with these dressings. Improvement in each case was observed.

A meta-analysis of published research enabled dressing efficacy to be estimated. Comparisons showed greater efficacy of hydrocolloid dressings but failed to confirm advantages of other advanced dressings compared with conventional ones.

objective: biopure® mtad (dentsply tulsa dental, usa) has been developed as a final irrigant following root canal shaping to remove intracanal smear layer. many of the unique properties of mtad potentially transfer to the conditioning process of tooth roots during periodontal therapy. the aim of this ex vivo study was to evaluate the effect of mtad on the removal of smear layer from root surfac...

AIM To evaluate and determine intracanal temperature rises at 2 and 4 mm from the working length (WL) necessary to obtain proper replication of intracanal anatomy with gutta-percha (GP) using the System B heat source during vertical condensation. METHODOLOGY A split-tooth model was prepared and artificial shallow depressions were cut in the buccal canal wall 2 and 4 mm from the WL. At the sam...
