BACKGROUND Surgical approach to type A acute aortic dissection (AADA) is usually dictated by the presenting anatomy. We compared long-term outcomes of AADA repaired with a root replacement versus a supracoronary tube graft, regardless of the proximal extent of the intimal tear. METHODS A single-centre, retrospective cohort of consecutive patients undergoing repair of AADA between December 199...

The presence of a missed canal in the course of root canal treatment is one of the common reasons for failure of therapy. The consequence of a missed canal will or may lead to chronic infection and post operative flare ups. Hence, it is very important to explore the morphology of the tooth as well its internal anatomy to overcome failure in endodontic practice. Root canal therapy of maxillary t...

Objective: Polygonatum (Asparagaceae) is a rhizomatous monocotyledon genus that distributed in the temperate regions of Northern Hemisphere. The represented by 5 species Turkey (P. glaberrimum, P. latifolium, multiflorum, verticillatum and orientale). Karyological, palynological, phylogenic, chemotaxonomical some anatomical studies have been carried out previously. However, detailed features sc...

Abstract Aims Growth reductions and yield losses from drought could be mitigated by developing rice genotypes with more efficient root systems. We examined spatiotemporal responses to in order determine whether roots upper vs. deeper soil layers respond differently stress. Methods Root anatomical architectural phenotypes of two genotypes, Azucena (drought tolerant) IR64 susceptible), were measu...

Aims Root canal treatment is a procedure that requires, beyond the realm of technique, knowledge of the internal anatomy of the root canal, specifically the anatomical apex. Almost all methodologies studied thus far are destructive, laborious, and time-consuming and allow for only one-dimensional measurements. In the present study, we used micro-CT technology to evaluate the anatomical structur...

This clinical article describes three different case reports of maxillary and mandibular second molars with the unusual anatomy of single root with a single canal and their endodontic management. An unusual case of bilateralism is observed in the first two cases in the form of single-rooted second mandibular molars in both the quadrant of the same patient. The presence of maxillary second molar...

The anatomy and pathophysiology of radiculopathies are reviewed, and the electrodiagnostic approaches used in evaluating patients with suspected root lesions are discussed. Such electrophysiologic procedures include motor and sensory nerve conduction studies, late-response studies, somatosensory and motor evoked potentials, nerve root stimulation, and needle electromyography. The value and limi...
