OBJECTIVE Identify and describe the separate appearance of 5 levator ani muscle subdivisions seen in axial, coronal, and sagittal magnetic resonance imaging (MRI) scan planes. METHODS Magnetic resonance scans of 80 nulliparous women with normal pelvic support were evaluated. Characteristic features of each Terminologia Anatomica-listed levator ani component were determined for each scan plane...

INTRODUCTION Root canal preparation is an important process in endodontic therapy. Nickel-titanium (NiTi) rotary file system can be used in single length technique (simultaneous technique) without early coronal enlargement, as well as in crown-down method. The purpose of this in vitro study was to compare single length with crown-down methods' shaping ability using Mtwo NiTi files. MATERIALS ...

We present an analysis of the Chandra High Energy Transmission Grating Spectrometer observation of the rapidly rotating (P rot = 0.94 d) post T Tauri (∼ 20 Myr old) star PZ Telescopii, in the Tucana association. Using two different methods we have derived the coronal emission measure distribution, em(T), and chemical abundances. The em(T) peaks at log T = 6.9 and exhibits a significant emission...

PURPOSE The purpose of this study is to report the comparative results of thoracoscopic correction achieved via cantilever technique using a 4.5 mm thin rod and the poly-axial reduction screw technique using a 5.5 mm thick rod in Lenke type 1 adolescent idiopathic scoliosis (AIS). MATERIALS AND METHODS Radiographic data, Scoliosis Research Society (SRS) patient-based outcome questionnaires, a...

OBJECTIVE The authors have recently been using a surgical technique of minimally invasive direct lateral interbody fusion (DLIF) for correcting of coronal imbalance. The purpose of this study was to evaluate the surgical outcome and complication of DLIF. METHODS We undertook retrospective analysis of a consecutive series of 8 DLIF procedures in Degenerative lumbar spine disease since May 2011...

AIM Anterior plagiocephaly usually occurs with premature synostosis of the ipsilateral half of the coronal suture. The forehead is flattened on the affected side, with a backward and upward displacement of the affected orbit. The bulging of the calvaria may occur in the contralateral parietal area. MATERIAL AND METHODS This article presents the surgical techniques used over 7 years to treat p...

Background and aims. Various factors influence the interfacial bond between the fiber posts and root canal dentin. The aim of the present study was to evaluate the effect of pre-warming of resin cement on the push-out bond strength of fiber posts to various segments of root canal dentin. Materials and methods. In this in vitro study, 40 single-rooted human premolars were decoronated and underwe...

The effect of a background signal on the signal-to-noise ratio is discussed, with particular application to ground-based observations of emission lines in the solar corona with the proposed Advanced Technology Solar Telescope. The concepts of effective coronal aperture and effective coronal integration time are introduced. Specific expressions are developed for the 1σ measurement errors for cor...

The exact knowledge of the topographical anatomy is not only a pre-requisite but also facilitates accurate clinical diagnosis during MRI, CT and ultrasonography. It becomes more fascinating if the anatomical specimen being used to study is dry, odourless, non toxic and not a wet specimen with formalin fumes. Such specimens can be procured by using a novel processing technique called plastinatio...

Pre-eruptive intracoronary resorption is a rare condition mainly affecting pediatric patients. It radiographic finding in the dentin of crown an unerupted tooth just below enamel-dentin junction. visualized radiographs as radiolucent coronal lesion variable depth; it well-defined and located adjacent to amelodentinal limit tooth. Historically, this was misdiagnosed caries misnamed pre-eruptive ...
