High-chromium white cast-iron specimens locally reinforced with TiC-metal matrix composites were successfully produced via an in situ technique based on combustion synthesis. Powder mixtures of Ti, Al, and graphite were prepared and compressed to fabricate green powder compacts that were inserted
BACKGROUND
Distinguishing inverted papilloma (IP) from malignant tumors in the nasal cavity is difficult in a substantial number of cases, thus hindering the administration of appropriate therapeutic strategies. This study aimed to evaluate whether magnetic resonance imaging (MRI), including dynamic
The authors studied two types of powdered alloy for amalgam without phase "Gamma-2"--"Stom-Am non gamma-2", production of TIC "Pharmachim", Bulgaria. They made obturations from the amalgams on trial to 45 healthy, extracted according to orthodontic indications, human teeth, preserved for 12 weeks in
OBJECTIVE
To determine the computed tomography (CT) and magnetic resonance imaging (MRI) features of leiomyoma of the sinonasal cavity.
METHODS
Six patients with histology-proven leiomyomas in the sinonasal cavity were retrospectively reviewed. All six patients underwent CT and three patients also
CONCLUSIONS
SFT is a rare lesion of the sinonasal cavity. We retrospectively reviewed 5 patients with histopathologically proved sinonasal SFTs to determine their CT and MR imaging features. All patients underwent paranasal sinus CT and MR imaging. Four SFTs occurred in the nasal cavity, and 1, in
OBJECTIVE
EAF consists of exceedingly rare lesions and presently lacks specific imaging reports. The purpose of this study was to determine the CT and MR imaging features of nasal cavity EAF.
METHODS
We retrospectively reviewed 6 patients with histology-proven EAF in the nasal cavity. All 6 patients
OBJECTIVE
This paper presents an own proposal for the construction of a ball latch intended for use in prosthetic dentistry. Attention was paid to the existing commercial constructions of elements of the same type, indicating their advantages and disadvantages. Based on the analysis of the present
BACKGROUND
Malignant sinonasal melanoma (MSM) is a rare tumor with a perplexing signal intensity due to variable histopathologic components. This study was undertaken to delineate its MR imaging features.
METHODS
MR imaging findings of 10 patients (6 women and 4 men, mean age 61.3 years old) with
The expression of the thyrotropin (TSH) gene in the pituitary gland is thought to be dependent upon the pituitary-specific transcription factor, Pit-1. TSH immunoreactivity is, however, widespread in extrapituitary tissues, and the possibility that this may reflect a widespread distribution of Pit-1
BACKGROUND
There has been some surmise that immunocompromised patients may not be candidates for endodon tic therapy.
OBJECTIVE
To compare the clinical presentation, treatment, and treatment outcomes of HIV+ve and HIV-ve patients receiving endodontic therapy.
METHODS
Fifty-nine HIV-ve and 46 HIV+ve
A retrograde radicular preparation in the axis of the root canal as well as an excess-free obturation of the canal is surgically very demanding due to the complex anatomical structures and to the limited intraoral operative field. As from the early 1990s, advisable methods for the retrograde root
BACKGROUND
Gilles de la Tourette syndrome is a neurological disorder characterized by motor and vocal tics. Extreme forms of this disease manifest themselves with self-mutilating behavior and foul language.
METHODS
A 59-year-old man, treated for Gilles de la Tourette syndrome, presented with visual
Children with obsessive compulsive disorder or tic disorders that are associated with streptococcal infections (Group A beta-hemolytic) in the oro-pharyngeal region are given the diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS).
Subcutaneous emphysema is a rare complication in oral surgery. In most cases, it resolves spontaneously. However, air might disperse into deeper facial spaces causing life-threatening complications such as compression of the tracheobronchial tree or the development of pneumomediastinum. Moreover,
BACKGROUND
Optical imaging systems are robust, portable, relatively inexpensive, and have proven utility in detecting precancerous lesions in the lung, esophagus, colon, oral cavity and cervix. We describe the use of light-induced endogenous fluorescence (autofluorescence) in identifying preinvasive
