Background and Aim: In the initial preparation stage, before feeding worms with organic wastes, the wastes are pre-composted for some time. This was done so that the thermophilic phase of organic wastes degradation is passed, no harm is done to the worms which are sensitive to high temperatures, production of fertilizer faster is quicker, and biological contamination is reduced. The length of t...
Colonoscopy is an important screening and therapeutic modality for colorectal cancer. Unlike other screening tests, colonoscopy is dependent on pre-procedure bowel preparation. If the bowel preparation is poor, significant pathology may be missed. Many factors are known to improve bowel preparation. This review will highlight those factors that may optimize the bowel preparation, including choi...
Background and Aim: The role of applying rotary instruments in reducing preparation time and proper root canal preparation have been approved in permanent teeth. The aim of this study was to compare the rotary instruments (Hero642) and K-files in root canal preparation of primary molars. Time and canal transportation were compared. Materials and Methods: In this experimental, invitro study, 30...
The aim of this study was to determine the frequency of medication errors happened during the preparation and administration of intravenous (IV) drugs. This study was designed as prospective cross-sectional evaluations by direct unconcealed observation in a setting consisted of orthopedic, general surgery and gastroenterology wards of a teaching hospital. Participants were those patients hospit...
Background: Surgery is a stressful experience in children. Therefore, the familiarization of this population with treatment processes by means of appropriate training tools and techniques can be an effective way to control their anxiety. Aim: The aim of this study was to determine the effect of a preoperative preparation program on anxiety in school-age children undergoing surgery using a facto...

introduction: preserving the apical root structure during cleaning and shaping of the canal has always been a challenge in endodontics particularly when the root canals are curved. the purpose of this in vitro study was to compare the apical transportation induced by the reciproc and biorace rotary systems in preparing the mesiobuccal root canal of the human maxillary molars. materials and meth...
background. maximum sealing ability or adhesion of endodontic sealers can be achieved after an effective removal of smear layer. endodontic irrigants assist in adequate removal of smear layer and thus improve the retention mechanism. the aim of this study was to evaluate the effect of two different root canal irrigating solutions (5.25% naocl followed by 17% edta and qmix) on the apical sealing...
