Breakage of instruments during laparoscopic surgery is rare. However, when it does occur, locating and retrieving the broken part of the instrument can be cumbersome. Moreover, inability to do so may carry serious medicolegal implications. We report a patient in whom the tip of a fascial closure device broke during laparoscopic surgery. This was located by intraoperative fluoroscopy and retriev...
Intentional replantation has been long considered to be the onlyrecourse for saving a tooth when other options like traditional root canal therapy and surgery are inconceivable. The article discusses intentional replantation as a treatment option for afallible case of broken instrument in the distal canal of left mandibular second molar. The critical factor required for the success of intention...
We report a unique case of a fractured modular cobalt chromium connection taper Revitan (Zimmer, Warsaw, IN) revision prosthesis. Macroscopic examination revealed a fracture at the diaphyseal-metaphyseal junction of this modular component. This report highlights that fractures can still occur with modern modular prostheses. We are not aware of any published failures of the Revitan revision pros...
different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...
Background and Aims: The aim of this descriptive longitudinal study was to determine the type of teeth that were more prone in accidental bracket debonding and also to investigate the relationship between broken bracket bond and intervening factors such as age, type of malocclusion and sex. Materials and Methods: We used a pilot study to determine the correct sample size for this study. Acc...
Introduction: One of the effective drugs in the treatment of cancer is dexamethasone. Dexamethasone is known as one of the safest glucocorticoid, but there is still side-effects, due to its hydrophobicity and low bioavailability. The purpose of the present study is to design a controlled release carrier for dexamethasone in order to overcome constraints and reduce side effects. Materials and Me...
