Comparative Evaluation of the Percentage of Gutta-percha Filled Areas in Canals Obturated with Different Obturation Techniques.

Aim: To evaluate the percentage of gutta-percha filled areas (PGFA) in canals obturated with guttacore system, single cone, and lateral compaction techniques.

Materials And Methods: A total of 60 single-rooted mandibular premolars were selected and randomly divided into three equal groups depending on the type of obturation technique used. After the obturation, the samples were marked at 2, 4, 6, and 8 mm distance from the apex and sectioned horizontally, and viewed under a stereomicroscope at 25×.

Comparative evaluation of the compressive, tensile, and flexural strengths of paracore®, flourocore®2+, and multicore® resin-based core build-up materials - An study.

Aims: The study was aimed to evaluate and compare the compressive, diametral tensile, and flexural strengths of three different commercial resin based core materials and to single out the best resin-based core build-up material with respect to their physical properties among ParaCore® (Coltene Whaledent, USA), FlouroCore® 2+ (Dentsply International, USA), MultiCore® (Ivoclar Vivadent, Liechtenstein) with Miracle Mix® (GC America) core used as control.

Materials And Methods: One hundred and twenty samples were prepared, of which forty samples (10 of each material) were prepared in cylindrical stainless steel molds (height 6 mm, diameter 4 mm) for compressive strength measurements. Other forty samples (10 of each material) were prepared in cylindrical molds (diameter 6 mm, height 2 mm) for diametral tensile strength measurements.

Evaluation of Cyclic Fatigue of Hyflex EDM, Twisted Files, and ProTaper Gold Manufactured with Different Processes: An In Vitro Study.

Introduction: The main aims of root canal instrumentation are to provide an environment that will lead to healing and to provide a root canal shape that is comfortable to clean and seal. When working with rotary endodontic instruments, the most significant concerns are that the instrument might fracture in the root canal, thus affecting the treatment outcome. Hence, it is of immense importance to know which file systems have more cyclic fatigue resistance.

Injury of anterior teeth is a relatively common event that mainly affects children and adolescents. Dentists are confronted with managing dental trauma and restoring fractured teeth on a regular basis. Hence the techniques that speed and simplify the treatment, restore esthetics and improve long term success rate are considered of potential value.

Maxillary first molar with two palatal roots located under dental operating microscope.

An awareness and understanding of the presence of an additional root and unusual root canal morphology is essential as it determines the successful outcome of endodontic treatment. A thorough knowledge of basic root canal anatomy and its variation is necessary for successful completion of endodontic treatment. This report points to the importance of looking for additional roots and canals with the help of operating microscope.

Adult cerebral malaria: prognostic importance of imaging findings and correlation with postmortem findings.

Purpose: To correlate imaging abnormalities, clinical features, and postmortem findings in patients with proved cerebral malaria.

Materials And Methods: Twenty-one patients aged 17-50 years with cerebral malaria consented to undergo transverse nonenhanced (10-mm sections) and contrast material-enhanced (8-mm sections in posterior fossa and 10-mm sections in supratentorial region) CT on admission (n = 21) and on day 10 (n = 6), with thin sections (5 mm) obtained in the area of abnormality. All CT scans were evaluated for diffuse cerebral edema, focal parenchymal abnormalities, and hemorrhage.

Massive pleural effusion as the presenting feature of a subarachnoid-pleural fistula.

A 14-year-old boy presented with a large symptomatic transudative pleural effusion 4 months after spinal surgery for kyphoscoliosis. Computed tomography myelography confirmed a subarachnoid-pleural fistula (SPF) with a pseudo-meningocele communicating with the left pleural space. A review of the literature indicates this to be a rare finding.
