cytotoxic effects of obturation materials were tested in presence and absence of endotoxin on human monocytes in vitro.human monocytes from thp-1 cell line were cultured. three millimeters from the tip of each resilon and gutta percha points were cut and directly placed at the bottom of the culture wells. cultured cells were exposed to gutta percha (groups g1 and g2) and resilon (r1 and r2). te...

background: the standard method for repair of an injured peripheal nerve is epineural repair with separate sutures. herein we describe a method in which the nerve is sutured with continous sutures. in fact this method has not been utilized for nerve repair previously and our purpose was to compare it to the standard method. if it proved to be successful it would replace the standard method in c...

In the generative literature, clause type effects have typically been modeled in one of two ways—“truncation” whereby embedded clauses are structurally reduced relative to root clauses, and intervention, by which non-root clauses have additional material that blocks movement available in root contexts. This paper analyzes two clause type effects in Basque— the possibility of verb-initial word o...

Internal resorption is rare in permanent teeth. Treatment is usually performed through warm gutta-percha technique. If the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. Non-surgical repair of a perforating internal root resorption with MTA was conducted in this case. Before repairing the resorption, a master gutta-percha ...

statement of problem: nowadays mineral trioxide aggregate (mta) is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments. investigations have shown similar physical and chemical properties for portland cement and root mta with those described for mta. purpose: the aim of this in vitro study was to evaluate the tissue reaction to implanted mta, portl...

OBJECTIVE Late aortic root dilatation is a growing concern in patients operated on for tetralogy of Fallot (ToF). This longitudinal follow-up study sought to evaluate the changes in the aortic root dimensions in relation to body growth, assuming that early repair of tetralogy of Fallot might prevent late aortic dilatation. METHODS A retrospective analysis of the aortic root dimensions was per...
