Sacred water canals or lakes, which provided for all kinds of purification rites and other activities, were very specific important features temples in ancient Egypt. In addition to the longer-known textual record, preliminary geoarchaeological surveys have recently evidence a sacred canal at Temple Bastet Bubastis. order further explore location, shape, course this find existence second waterw...

Regenerative endodontic procedures are the emerging techniques for the restoration of functional pulp and dentine. The case report presented here describes the management of a symptomatic mandibular first molar with an immature apex and necrotic pulp in a 9 year old child. The tooth was tender on percussion and palpation and elicited a negative response to sensibility testing. A regenerative en...

PURPOSE The main strategy in inguinal hernia repair is mesh hernioplasty (specially prolene mesh). Pain in anterior femoral, inguinal and scrotal areas, mainly due to sensory nerve injury in the very regions and vas deferen injury are the main complications reported following repairing inguinal hernia. In this study we decided to use semiliquid silicone in order to form it in an in-vivo prosthe...

INTRODUCTION The aim of this study was to compare the dentine removing efficacy of Gates-Glidden drills with hand files, ProTaper and OneShape single-instrument system using cone-beam computed tomography (CBCT). METHODS AND MATERIALS A total of 39 extracted bifurcated maxillary first premolars were divided into 3 groups (n=13) and were prepared using either Gates-Glidden drills and hand instr...

Teeth with open apices, such as in immature teeth or those with apical root resorption are clinical cases with difficult immediate resolution. With the use of mineral trioxide aggregate (MTA) in dentistry, it was possible to optimize the treatment time of these cases by immediate placement of apical plug and the root canal filling. However, some negative effects can occur if MTA is extruded bey...

INTRODUCTION The aim of this in vitro study was to evaluate the bond strength of Photo-Activated Disinfection (PAD) system to dentin with different root canal sealers by using a push-out test design. MATERIALS AND METHODS A total of 30 extracted mandibular premolar teeth with single and straight roots were used. The crowns were removed and the root canals were prepared by using ProTaper rotar...

The Cretaceous Sanagasta neosauropod nesting site (La Rioja, Argentina) was the first confirmed instance of extinct dinosaurs using geothermal-generated heat to incubate their eggs. The nesting strategy and hydrothermal activities at this site led to the conclusion that the surprisingly 7 mm thick-shelled eggs were adapted to harsh hydrothermal microenvironments. We used micro-CT scans in this ...

A measure of insulation film floating on the water surface was put forward to solve problems ice damage delivery canals during winter operation period in cold regions. Firstly, a circulating flume test system designed an indoor radiation- and temperature-controlled environment. Secondly, five groups comparative tests were carried out according different application scenarios. Lastly, combined w...

A three-dimensional model of interstitial fluid flow and passive species transport within mineralized regions surrounding cross-cortical vessel canals is developed. In contrast to earlier studies, the present model applies to circulatory, non-stress-induced interstitial flow in porous cortical bone. Based on previous experimental observations, the canals are modeled as line sources that pass at...
