introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

BACKGROUND Data on outcomes after Stanford type A aortic dissection in patients with Marfan syndrome are limited. We investigated the primary surgery and long-term results in patients with Marfan syndrome who suffered aortic dissection. METHODS AND RESULTS Among 1324 consecutive patients with aortic dissection type A, 74 with Marfan syndrome (58% men; median age, 37 years [first and third qua...

statement of problem: mineral trioxid aggregate (mta) cement is widely used for root-end filling, pulp capping, perforation repair and other treatments in endodontics. investigations have shown similar physical and chemical properties for portland cement (type i), root mta and proroot mta. purpose: the aim of this in vivo study was to evaluate the reaction of dog canine pulp after pulp capping ...

BACKGROUND The goal of this study was to compare the early and late outcomes of different techniques of proximal root reconstruction during the repair of acute Type A aortic dissection, including aortic valve (AV) resuspension, aortic valve replacement (AVR), and a root replacement procedure. METHODS All patients who underwent acute Type A aortic dissection repair between January 2000 and Oct...

The aim of this study was to determine the feasibility of the new vascular graft for aortic root reconstruction using two different surgical techniques and to evaluate the intermediate clinical and functional results. Between January 2006 and December 2007, a total of 79 patients with aortic root and valve pathologies (chronic aneurysm 70, acute aortic dissection 9) underwent valve-sparing aort...

The aortic root remodelling procedure, introduced by Yacoub in the early 1980s, is the valve-sparing aortic root replacement procedure that better reproduces the anatomical and functional properties of the native aortic root. Long-term durability of the repair, in terms of freedom from recurrent aortic regurgitation, has been questioned and can probably be improved by appropriate patient select...

Background Currently, clinical endodontics includes procedures that are based on the ability of stem cells to accomplish repair (eg, direct pulp capping, apexogenesis, apexification, and even pulpal regeneration). An attempt is made to critically assess the current status in pulp regeneration therapy. Methods: Systematically, 2 distinctly different strategies exist involving stem cells for t...
