a detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. such information is highly dependent upon the ethnicity of the population of interest. lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. the aim of this study was to evaluate external root morphology and root canal a...

Aortic valve stenosis constitutes 3-6% of congenital heart diseases with an incidence of 1-4 per 10,000 live births (Khalid et al, 2006). The prevalence of aortic stenosis at birth is 0.03% (Mahle et al, 2010). If left untreated, it can lead to considerable morbidity and mortality in neonates, infants, children and adults. Until three decades ago, the only treatment that could be offered to chi...

The association of bicuspid aortic valve with aortic stenosis, aortic regurgitation, and infective endocarditis has been known for almost 150 years and with dissection of the aorta for 75 years. These complications are mentioned only briefly in cardiology textbooks and a standard work on medical insurance underwriting implies that it is usually a benign lesion: when diagnosed at routine medical...

OBJECTIVE Long-term evaluation of the impact of bicuspid pulmonary valve on neoaortic valve regurgitation and aortic root dilatation (ARD) after arterial switch operation (ASO) for transposition of the great arteries (TGA). METHODS Between January 1987 and March 2010, 980 neonates underwent ASO for TGA. A total of 40 patients (4.0%) had a pulmonary bicuspid valve with no significant left vent...

Orthodontic treatment for malocclusion correction may involve extraction or non-extraction of specified teeth for esthetic and functional harmony. Antero-posterior and transverse arch dimensional changes following orthodontic treatment has been evaluated using many methods. The present study evaluated the arch dimensional changes after orthodontic treatment in extraction and non-extraction case...

Doppler-derived gradients may overestimate total pressure loss in degenerative and prosthetic aortic valve stenosis (AS) due to unaccounted pressure recovery distal to the orifice. However, in congenitally bicuspid valves, jet eccentricity may result in a higher anatomic-to-effective orifice contraction ratio, resulting in an increased pressure loss at the valve and a reduced pressure recovery ...

Patients with bicuspid aortic valve (BAV) are more likely to develop a calcific aortic stenosis (CAS), as well as a number of other ailments, as compared to their cohorts with normal tricuspid aortic valves (TAV). It is currently unknown whether the increase in risk of CAS is caused by the geometric differences between the tricuspid and bicuspid valves or whether the increase in risk is caused ...

OBJECTIVE Bicuspid aortic valve (BAV) may be considered in the context of a phenotypic continuum of the aortic valve configuration, ranging from severe forms of unicuspid valve to rare forms of quadricuspid valve. In this article, we report our results with BAV repair using surgical techniques tailored to the specific features of the BAV phenotypic continuum. PATIENTS AND METHODS Between Sept...
