The present study was conducted to compare the cleaning efficacy (debris and smear layer removal) of hand and two NiTi rotary instrumentation systems (K3 and ProTaper).

Staphylococcus aureus is frequently found in patients with atopic dermatitis (AD) and contributes to disease exacerbation. The objective of this study was to evaluate the efficacy and safety of bleach baths as an adjunctive treatment in AD patients. Patients between 2 and 30 years old with moderate to severe AD were enrolled in a prospective, randomized, placebo-controlled study. Patients soaked in diluted bleach or distilled water baths for 10 min, twice a week for 2 months. Efficacy assessments included the Eczema Area and Severity Index (EASI) scores and S. aureus density was determined using quantitative bacterial cultures. Patients in the treatment group showed significant reductions in EASI scores. A 41.9% reduction in S. aureus density from baseline was seen at 1 month further reducing to 53.3% at 2 months. Equal numbers of patients in both groups experienced mild side-effects. This study demonstrates that diluted bleach baths clinically improved AD in as little as 1 month. No patient withdrew from the treatment arm because of intolerance to the baths.
Sternal wound infection is an infrequent yet potentially devastating complication following sternotomy. Among the standard practices used as preventive measures are the use of prophylactic antibiotics and povidone-iodine as an irrigation agent. A new antiseptic agent, Dermacyn super-oxidized water (Oculus Innovative Sciences), has recently been used as a wound-irrigation agent before the closure of sternotomy wounds.
The aim of this study was to evaluate in vitro the apical sealing ability of cold lateral and system B root filling techniques using dye penetration. Eighty-six extracted single-rooted human teeth were prepared and randomly divided into two experimental groups to be obturated by cold lateral condensation (n = 33) and system B (n = 33). The remaining 20 teeth served as positive and negative controls. The roots were embedded for 72 h in methylene blue dye solution and sectioned transversely for dye penetration evaluation using stereomicroscope. The results of this study showed that cold lateral condensation leaked significantly more (P < 0.001) than system B technique.
