Various surgical techniques for the removal of a foreign body from maxillary sinuses have been reported. However, the access window in the lateral wall of the maxillary sinus cavity is not replaced by a bony wall when sinus grafting is not performed. The replaceable bony window provides an access window into the sinus cavity and maintains the integrity of the lateral wall of the sinus cavity af...

Echocardiograms were recorded in 154 active athletes (from various sports) and 21 ex-athletes and compared with those in 40 normal control subjects (non-athletes). Diastolic cavity dimension and posterior wall and septal thickness were measured and left ventricular mass and the ratio of posterior wall thickness to cavity radius and of septum to posterior wall thickness calculated. As a group at...

Viscoelastic flow in a square cavity is studied in detail for the FENE-CR model with a given value of extensibility. A finite volume method was employed to predict both the steady flows resulting from movement of the top cavity wall and also the recoil flows that follow the cessation of that lid-wall motion, when the fluid possesses viscoelastic properties. It is shown that this recoil flow can...

Computational Fluid Dynamics is used to model airflow and penetrant behaviour under cough reflex in human airway. The airway geometry segment from the oral cavity primary bronchi reconstructed CT scan images of a subject standing posture. inlet flow condition derived dynamic profiles obtained two subjects. mathematical allows laryngopharyngeal wall remodel. A k-ω turbulence represent transition...

Secondary oral cavity neoplasms are rare. We describe a case of an indurated, nonulcerating gingival lesion in a 59-year-old nonsmoking man with no family history of lung cancer. The lesion was the presenting symptom of metastatic lung adenocarcinoma. Reviewing the literature, we find that primary lung cancer among men is one of the most common cancers to metastasize to the oral cavity. Renal a...

During the past 25 years, there has been disagreement regarding the existence of H. pylori in the oral infection. It was proposed that no living H. pylori exists in the oral cavity and that the positive results detected by a polymerase chain reaction (PCR) in the oral cavity may be a fragment of H. pylori, instead of living bacteria, as part of a reflux from the stomach: H. pylori could not be ...

The aim of this study was to evaluate the in vitro antifungal activity of Schinus terebinthifolius (Brazilian pepper tree) tincture on planktonic Candida tropicalis (ATCC 40042), which is a microorganism associated to oral cavity infections. Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) were determined through the microdilution technique. Possible action of t...

Aggressive fibromatosis is a rare soft tissue tumor that composes of myofibroblasts that arise from musculoaponeurotic structures. It usually affects the abdominal wall but may be also found in other less common sites including the head and neck, submucosa of the oral cavity, spinal, haunch and limbs, especially, the limbs and sacrococcygeal region are rare locations. We described two cases of ...
