Pathologies of the implant cavity wall currently cannot be diagnosed by direct observation because of the rapid pollution of the optical systems used. A technique to examine prepared implant sites intraoperatively to diagnose possible risk factors for the osseointegration process is presented. Examination of implant cavities is performed with support immersion endoscopy (SIE). Using a specially...

Fighting the controversies, amalgam, as a posterior restorative material has survived till date. The fate of amalgam restoration is determined by geometry of the cavity preparation and cavosurface angle is one integral part of the cavity, which decides the marginal characteristics of the restoration and health of the tooth. Low edge strength of amalgam highlights the importance of cavosurface a...

We present in this paper an analysis of the damage imposed by atom field state inside a lossy superconducting cavity. To access such effects, we propose two procedures to preserve qubit from decay effects imperfect quantum memory: first means quasi-instantaneous phase kick applied and second controlled resonant dispersive interactions. immediately demonstrate that, both procedures, dwell time c...

Restoration of endodontically treated teeth is one the major challenges faced in field operative dentistry. In tooth, most part tooth structure lost because dental caries, conventional access cavity preparation and biomechanical during root canal therapy. They become very weak brittle also more prone to fracture compared vital

A status report of the superconducting RF photo electron injector development at Forschungszentrum DresdenRossendorf (FZD) is given. The SRF gun project is a collaboration of BESSY, DESY, MBI and FZD and aims at the installation of a high average current CW photo injector at the ELBE superconducting electron linac. Main design parameters of the SRF gun are an electron energy of 9.5 MeV, a maxim...

Background Abnormal uterine bleeding (AUB) is one of the most common clinical problems in gynecology. Transvaginal sonography (TVS) and hysteroscopy are two diagnostic methods for patients with AUB. For most of the patients with AUB, diagnostic hysteroscopy can be done in clinic with minimal discomfort and much lower expense than operative room. MaterialsAndMethods In our clinical trial study, ...

Accelerating gradients in SRF cavities have consistently been increasing in recent years, largely due to better surface preparation techniques. This makes the critical magnetic eld, at which the cavity loses its superconductivity, a very important limit to address. We worked to minimize the peak magnetic eld Hpk on the surface of the cavity with respect to the acceleration rate Eacc. Allowing t...

iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. the present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (cem) cement. the perforation was chemically cleaned and then physical...
