Nowadays, in endodontic field mineral trioxide aggregate (MTA; Dentsply, Tulsa Dental, Tulsa, OK, USA) has been introduced and widely used in many indications such as root-end filling, perforation repair, apexification, and pulp capping. Traditionally, various materials, such as amalgam, zinc oxide eugenol (ZOE), Intermediate Restorative Material (IRM; Dentsply Caulk, Milford, DE, USA), and sup...

PURPOSE To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling materia...

OBJECTIVES The purpose of this study was to determine whether restrictive left ventricular (LV) filling patterns are associated with diastolic ventricular interaction in patients with chronic heart failure. BACKGROUND We recently demonstrated a diastolic ventricular interaction in approximately 50% of a series of patients with chronic heart failure, as evidenced by paradoxic increases in LV e...

conclusions there was no significant statistical difference between mta and cem cement in sealing ability (p > 0.05). results the mean apical penetration of dye in the mta group was 0.94 mm while in the cem cement group this was 1.17 mm. eighty percent of the mta group and 75% of the cem cement group didn’t have any dye leakage. the p level was greater than 0.05 (0.592). materials and methods e...

introduction: sealing ability is an important factor for a root-end filling material in endodontic surgeries. this in vitro study aimed to compare the sealing ability of mineral trioxide aggregate (mta) and a new endodontic cement named calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: the experiments were carried out in dry, saliva or blood contaminate...

The effects of alterations in the diastolic filling pressure of the right ventricle on left ventricular (LV) geometry and filling pressure were studied in six isolated, supported canine hearts. This experimental preparation permitted graded increments in right ventricular (RV) end-diastolic pressure while LV cardiac output, heart rate, and mean aortic pressure were held constant. Endocardial ra...

In this paper, we describe a method to load a microfluidic device, the SlipChip, via dead-end filling. In dead-end filling, the lubricating fluid that fills the SlipChip after assembly is dissipated through the gap between the two plates of the SlipChip instead of flowing through an outlet at the end of the fluidic path. We describe a theoretical model and associated predictions of dead-end fil...

this case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. in all represented cases, calcium enriched mixture (cem) cement is used for root-end filling. this case series demonstrates twenty cases of ir and extraoral root-end resection and filling with cem cement. all the selected teeth had a failed endodontic tr...
