Enhancing Coronal Adaptation of Root Canal Fillings with a Modified Single-Cone Obturation Technique: Two Case Reports.

The single-cone technique, also known as the hydraulic condensation technique, is widely employed in endodontics. However, the aforementioned method is presented with certain limitations; specifically concerning the coronal seal and the adaptation of the coronal third of a master gutta-percha (GP) with a round cross-section to the coronal dentinal walls of root canals with semi-round or oval cross-sections. Through two case reports, the current article introduces the coronal vertical condensation (CVC) technique; aiming to enhance GP adaptation to canal walls in similar scenarios.

Micro-CT Evaluation of Four Root Canal Obturation Techniques.

Purpose: The aim of this study was to evaluate the quality of four root canal obturation techniques using microcomputed tomography (micro-CT).

Materials And Methods: A total of 36 mandibular first premolars with mostly round canals were decoronated, then instrumented up to a size F3 rotary file, and dressed with an epoxy resin-based sealer. Subsequently, they were divided into 4 different groups ( = 9) based on the method of obturation: lateral condensation using 0.

Biopsy-proven vancomycin-associated interstitial nephritis and acute tubular necrosis.

Fewer than ten biopsy-proven case reports exist on vancomycin-associated interstitial nephritis (VAIN) and vancomycin-associated acute tubular necrosis (VAATN). Among these, several are confounded by the use of other potentially offending drugs. We report a case of isolated VAIN/VAATN in a patient on no other potentially nephrotoxic agents other than vancomycin.

Use of antibacterial agents in renal failure.

This article provides background information on the pharmacokinetics of antibacterial agents in patients who have normal and impaired renal function. Tables are provided to allow quick determination of appropriate dosages for varying degrees of renal failure. The use of serum levels; newer strategies for cefazolin, vancomycin and aminoglycoside dosing; methods of dialysis and associated antibiotics dosage adjustments, and antibiotic toxicity in renal failure are reviewed.

Disseminated Nocardia otitidiscaviarum infection in a woman with sickle cell anemia and end-stage renal disease.

Nocardia otitidiscaviarum is an uncommon human pathogen and a rare cause of pulmonary infection and bacteremia. We report a case of N. otitidiscaviarum bacteremia and pulmonary infection in a patient with end-stage renal disease (chronic kidney disease, stage 5) and sickle cell anemia.

Torque resistance after fixation of Jones fractures with intramedullary screws.

Background: Intramedullary screws frequently are used for fixation of Jones fractures of the fifth metarsal. While the ability of intramedullary screw fixation in fifth metatarsals to resist bending and tensile forces is well known, the ability to withstand torsion has not been studied. This paper compares the torsional stiffness of Jones fractures treated with 6.

Avascular necrosis of the talus: current treatment options.

AVN of the talus is a challenging disease process with respect to patho-physiology and treatment. We believe that our algorithm is a legitimate approach to aid the orthopedic surgeon in initiating a promising treatment. It is divided into different levels and allows to change between some.

Potential donor rotational bone grafts using vascular territories in the foot and ankle.

Background: An improved understanding of the extraosseous and intraosseous blood supply of the distal aspect of the tibia, distal aspect of the fibula, cuboid, and cuneiforms should identify vascular territories that would enable surgeons to perform rotational vascularized pedicle bone-grafting procedures in the foot and ankle.

Methods: We investigated the blood supply of twenty cadaveric lower extremities using two vascular injection techniques. In order to define the extraosseous and intraosseous arterial anatomy in this region, ten specimens were sequentially subjected to injection with Batson's compound, soft-tissue digestion, and bone-clearing according to a modified Spalteholz technique.
