aim: the aim of this study was to compare cusp deflection, infraction and fracture in teeth filled with three temporary filling materials. materials & method: forty five extracted human premolar teeth were chosen. after root canal therapy and mesio-occluso-distal cavity preparation, samples were randomly divided into three groups , each contained 15 teeth and filled with three temporary filling...

Tarsorrhaphy is used for the treatment of severe ocular surface disorders and for damage from ocular exposure. The temporary tarsorrhaphy has been shown to aid in the healing of corneal epithelial defects. A variety of temporary techniques have been suggested that allow eyelid closure not only to enable epithelial healing but also to allow access to the eye. We describe a temporary eyelid closu...

Temporary tinnitus is a common consequence of noise exposure, and may share important mechanisms with chronic tinnitus. Noise-induced hearing loss is the most prevalent cause of chronic tinnitus. The reversibility of temporary tinnitus offers some practical experimental advantages. We therefore adapted a behavioral method based on gap detection to measure temporary tinnitus following brief acou...

The Epistemic Objection says that certain theories of time (like the “growing block” and “moving spotlight”) imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in t...

In the previous work dealing with naturally occurring trypsin inhibitors it has been generally assumed or at least implied that as long as the inhibitor is capable of reacting with trypsin the inhibitor is resistant to tryptic digestion. In the present paper a system is described in which trypsin is first inactivated by the inhibitor and then released, owing to the digestion of the inhibitor. T...

BACKGROUND Although temporary cardiac pacing is infrequently needed, temporary epicardial pacing wires are routinely inserted after valve surgery. As they are associated with infrequent, but life threatening complications, and the decreased need for postoperative pacing in a group of low risk patients; this study aims to identify the predictors of temporary cardiac pacing after valve surgery. ...
