in this study 100 cases of advanced periodontitis were compared with a control group of 100 persons. the parameters were the depth of the periodontal pockets, radiographic images, presence of inflammatory cells and different types of anaerobic bacteria in the pockets. the depth of pocket was measured by a sterile probe and the presence of inflammatory cells was determined through sterile curett...

A filling operation generates continuous changes over the shape of an air–water interface, which can be captured using a 3D CFD model. This research analyses influence different hydro-pneumatic tank pressures and air pocket sizes as initial conditions for studying rapid operations in 7.6 m long PVC pipeline with irregular profile, OpenFOAM software. The analysed scenarios were validated experim...

We encountered an unusual case of an intracranial wooden stick penetrating through the frontal bone, without remarkable neurological findings. That foreign body was shown to be a low-density area similar to an intracranial air pocket by a standard computed tomogram. Here we discuss the potential hazards of intracranial wooden foreign bodies and emphasize the necessity for special attention to t...

AIMS To describe a new surgical technique for deep stromal anterior lamellar keratoplasty. METHODS In eye bank eyes and sighted human eyes, aqueous was exchanged by air, to visualise the posterior corneal surface--that is, the "air to endothelium" interface. Through a 5.0 mm scleral incision, a deep stromal pocket was created across the cornea, using the air to endothelium interface as a refe...
