People’s lives have been profoundly impacted by the headway of innovation which has worked on their from each viewpoint. Clearly, assumes a significant part in circle life and information stockpiling sharing is it. Current storage devices depend trusted third parties (TTP) because contribution parties, such frameworks need straightforwardness, security, trust strength. To solve these issues, th...

introduction: presence of surface defects in endodontic instruments can lead to unwanted complications such as instrument fracture and incomplete preparation of the canal. the current study was conducted to evaluate the effect of autoclave cycles on surface characteristics of s-file by scanning electron microscopy (sem). methods and materials: in this experimental study, 17 brand new s-files (#...

conclusions the causes leading to fracture of the humerus during the act of a throw are discussed and the management strategies utilized. introduction five patients presented to the emergency department of a tertiary referral teaching hospital with atraumatic fractures of their humerus sustained during a recreational dodgeball tournament. case presentation the patients were young healthy indivi...

background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...

introduction: fractures of the orbital floor, which are caused by various mechanisms, result in the herniation of periorbital tissue into the paranasal sinuses and its subsequent complications. early diagnosis using various techniques and reduction of fractures are necessary to preserve ocular function and esthetic. use of an endoscope has been associated with some advantages, including a decre...

introdouction: canal length measurement is essential for proper endodontic treatment. any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. digital radiography has enabled accurate measurement of curved canal length. in this study, we evaluated the accuracy of calibration of a complementary met...

Preparation of the root canal system is a crucial step in treatment. Endodontically treated teeth differ structurally from healthy, untreated teeth. This can lead to cracking by creating pressure on wall, reducing fracture resistance tooth. Different designs, including cross-sectional shape, tip, taper, flute, radial land, helix angle, rake and pitch, influence outcome preparation risk fracture...
