OBJECTIVES/HYPOTHESIS Laryngeal transplantation offers the potential for patients without a larynx to recover their voice, which is critical in our communication age. We report clinical and functional outcomes from a laryngotracheal transplant. Widespread adoption of this technique has been slowed due to the ethical concerns of life-long immunosuppression after a nonvital organ transplant. Our ...

This study compared the antimicrobial effectiveness of nine dental materials and a negative control agent against 21 strains or species of bacteria using an agar diffusion assay. The materials were: 1. Camphorated parachlorophenol mixed with calcium hydroxide (CPC + Ca(OH)2). 2. CPC mixed with zinc oxide (CPC + ZnO). 3. Formocresol mixed with zinc oxide and eugenol (FC + ZOE). 4. Chlorhexidine ...

Rmoval of abscessed primary teeth has been sug;ested because they have been shown in some tudies to create developmental defects with underlying permanent successors.' However there might be a rationale for attempting pulp therapy in some carefully selected cases, i.e., abscessed incisor prior to eruption of primary cuspids, as space closure may occur. In necrotic immature teeth, the wide and f...

AIM To investigate radiographic manifestations of sickle cell anaemia (SCA) and whether or not a pulpal necrosis may develop without a pathological history. METHODOLOGY Thirty-six patients with homozygous SCA were evaluated, and a further 36 individuals without SCA were included in the study as a control group. All 72 patients participating in the study ranged between the ages of 16 and 40 ye...

INTRODUCTION This retrospective cohort study compared clinical and radiographic outcomes of endodontic treatment performed in immature nonvital permanent teeth by apexification (calcium hydroxide or apical barrier with mineral trioxide aggregate) versus revascularization. METHODS A comprehensive chart review was performed to obtain a cohort of previously completed cases with recalls. Clinical...

This study evaluated the microtensile bond strength (μTBS) of 1-step self-etch adhesives (1-SEAs) and 2-step self-etch adhesives (2-SEAs) to pulp chamber dentin immediately after bleaching with 2 types of common bleaching techniques. Pulp chamber dentin of bovine teeth was bleached using 30% hydrogen peroxide (H2O2) solution with quartz-tungsten-halogen light-curing unit (Group 1) and 3.5% H2O2...

An important aspect of Business to Business ECommerce is the agile Virtual Enterprise (VE). VEs are established when existing enterprises dynamically form temporary alliances, joining their business in order to share their costs, skills and resources in supporting certain activities. Currently, existing enterprises use workflows to automate their operation and integrate their information system...

It is a well-known fact that cache hits are vital to superscalar processor performance. The successful execution of a load allows resources to be freed up and it also allows dependent instructions to proceed to execution. As processor cores operating frequencies rise rapidly, the cache hierarchy is struggling to keep up in terms of speed while still trying to provide good hit rates, because the...
