PURPOSE Preparation of a one-piece dental implant abutment is often needed to achieve a proper emergence profile for a definitive restoration. However, this procedure may compromise osseointegration through the production of heat. The aim of this study was to measure heat production during implant abutment preparation with different volumes of water irrigation using a one-piece implant system. ...

OBJECTIVE One or two burr-hole craniostomies with subgaleal or subdural drainage system and irrigation are the most common methods for surgical treatment of CSDH. The aim of this study is to compare the advantages or disadvantages of these techniques used for CSDH. METHODS Seventy patients were treated by burr-hole subdural drainage or subgaleal drainage system with irrigation. Our patients w...

This study was carried out to investigate the effect of treated wastewater on soil chemical and physical properties. Field experiment was conducted in Borkhar region in Isfahan province in central Iran with two water treatments of wastewater and groundwater under sprinkler and surface irrigation systems for three crops of sugar beet, corn and sunflower. Soil samples were collected to 120 cm dep...

For improving water scarcity and groundwater pollution from agriculture, two-year experiments (2011–2013) with three water levels (0.3, 0.5 and 0.8 evaporation (E) in 20-cm-diameter pans) and four nitrogen (N) levels (120, 140 and 190 kg·ha−1 in 2012 and 120, 190 and 290 kg·ha−1 in 2013) were conducted to study effects of water and N availability on water movement and N transport for a wheat cr...

Freshwater resources in the North China Plain (NCP) are near depletion due to the unceasing overexploitation of deep groundwater, by far the most significant source of freshwater in the region. To deal with the deepening freshwater crisis, brackish water (rich but largely unused water in agriculture) is increasingly being used in irrigation in the region. However, inappropriate irrigation with ...

In recent decades, many technical improvements have been achieved in the use of prosthetic joints, and the risk of infection has been greatly reduced, to current rates of 0.4-2.0% following primary knee replacement. However, the increasing rate of joint replacements being performed means that the absolute number of such infections remains significant and poses substantial costs to healthcare sy...

PURPOSE The aim of the present study was to evaluate and to compare the antibacterial effects of various irrigation solutions against Staphylococcus aureus (S. aureus) in human root canals. MATERIALS AND METHODS 120 single-root mandibular premolar teeth were selected. The teeth were prepared and sterilized. S. aureus was incubated in the root canals and kept at 37°C for 24h. The infected root...

AIM To determine the influence of activation method (ultrasound or laser), concentration, pH and exposure time on the reaction rate (RR) of NaOCl when in contact with dentinal walls. METHODOLOGY The walls from standardized root canals in bovine incisors were exposed to a standardized volume of sodium hypochlorite (NaOCl) with different concentrations (2% and 10%), pH (5 and 12) and exposure t...

Several studies have indicated that pain peaks at 24 to 48 hours after total knee arthroplasty (TKA) surgery. TKA has been associated with disruption in normal sleep patterns, swelling knee, and significant blood loss. However, a satisfactory regime to resolve these mentioned problems has yet to be found.In this study, a total of 420 patients were randomly allocated into two groups and treated ...
