introduction: this study aimed to evaluate the dentin-sealer interface in three different sealers using scanning electron microscopy (sem). methods and materials: thirty extracted human single-rooted teeth were prepared using protaper rotary files and were randomly divided into three groups ( n =10) including bc sealer, ah-plus and dorifill. the root canals were filled with cold lateral condens...

Biochar (BC) addition to soil is a proposed strategy to enhance soil fertility and crop productivity. However, there is limited knowledge regarding responses of soil respiration and C-cycle enzyme activities to BC and nitrogen (N) additions in a calcareous soil. A 56-day incubation experiment was conducted to investigate the combined effects of BC addition rates (0, 0.5, 1.0, 2.5 and 5.0% by ma...

introduction: the aim of this in vitro study was to evaluate the effect of canal dryness on the push-out bond strength of two resin sealers (ah-plus and adseal) and a bioceramic sealer (endosequence bc sealer) after canal irrigation with sodium hypochlorite (naocl) and chlorhexidine (chx). methods and materials: a total of 18 extracted human premolars were used. canals were prepared and were di...

OBJECTIVES Recently, bioceramic sealers like EndoSequence BC Sealer (BC Sealer) have been introduced and are being used in endodontic practice. However, this sealer has limited research related to its retreatability. Hence, the aim of this study was to evaluate the retreatability of two sealers, BC Sealer as compared with AH Plus using micro-computed tomographic (micro-CT) analysis. MATERIALS...

Deficiency of the granulocyte-macrophage colony-stimulating factor (GM-CSF)/interleukin-3 (IL-3)/IL-5 receptors common b chain (bc) is a cause of fatal respiratory failure. bc deficiency manifests as pulmonary alveolar proteinosis (PAP). PAP has heterogenous etiologies that may be genetic or aquired. Some cases of PAP have been reported to be associated with hematologic malignancies such as acu...

INTRODUCTION This study aimed to evaluate the dentine-sealer interface in three different sealers using scanning electron microscopy (SEM). METHODS AND MATERIALS Thirty extracted human single-rooted teeth were prepared using ProTaper rotary files and were randomly divided into three groups (n=10) including BC Sealer, AH-Plus and Dorifill. The root canals were filled with cold lateral condensa...

Detection and identification of anaerobic bacteria in blood cultures (BC) is a well-recognized challenge in clinical microbiology. We studied 100 clinical anaerobic BC isolates to evaluate the performance of BacT/ALERT-FN, -FN Plus (BioMérieux), BACTEC-Plus and -Lytic (Becton Dickinson BioSciences) BC bottles in detection and time to detection (TTD) of anaerobic bacteria. BACTEC Lytic had highe...

INTRODUCTION The aim of this study was to investigate in vitro the cytotoxicity and antibacterial properties of four different endodontic sealers using human periodontal ligament fibroblast cell proliferation and visual analysis of growth inhibition. METHODS A silicone (GuttaFlow), silicate (EndoSequence BC), zinc oxide eugenol (Pulp Canal Sealer EWT) and epoxy resin (AH Plus Jet) based seale...

BACKGROUND Intensive chemotherapy frequently results in gut toxicity, indicated by oral and intestinal mucositis, resulting in poor treatment outcomes and increased mortality. There are no effective preventive strategies against gut toxicity and the role of diet is unknown. OBJECTIVE We hypothesized that the severity of chemotherapy-induced gut toxicity in early life is diet-dependent, and th...

conclusions clonidine plus bupivacaine can increase the duration of motor and sensory block in arthroscopic cruciate ligament repair under spinal anesthesia. however, due to significant hemodynamic changes, further studies are required to determine a safer dose. results all patients were males with a mean age of 24.9 years in group b, and 25.2 years in group bc (p > 0.05). in group bc, time lap...
