Background:
 Dental impressions become contaminated with micro-organism from patient’s saliva and blood which can cross-infect stone cast poured against them. The aim of the present study was to compare efficacy commercially available disinfection products, one containing glutaraldehyde, sodium hypo chloride ethanol for material.
 Methods: For this investigations, dental impression 60...

STATEMENT OF THE PROBLEM The stability of orthodontic treatment depends on preserving the patient's pretreatment arch form and arch size during and after treatment. PURPOSE This investigation was aimed to study the size and shape of Iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...

The overall aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. Cephalometric analysis, cast model analysis concerning palatal height, dental arch morphology and dental crown width were performed. Eightee...

The cytomatrix at the active zone (CAZ) has been implicated in defining the site of Ca2+-dependent exocytosis of neurotransmitter. We have identified here a novel CAZ protein of approximately 120 kD from rat brain and named it CAST (CAZ-associated structural protein). CAST had no transmembrane segment, but had four coiled-coil domains and a putative COOH-terminal consensus motif for binding to ...

background: the accuracy and reproducibility of measurements in a locally made three dimensional (3d) simulator was assessed and compared with manual caliper measurements. materials and methods: a total of 20 casts were scanned by our laser scanner. software capabilities included dimensional measurements, transformation and rotation of the cast as a whole, separation and rotation of each tooth ...

The basis for developing a new dental alloy with high Au content is appropriate chemical composition and manufacturing technology. The demands which have to be met when developing a new dental alloy are linked with fulfilling the necessary requirements for making the alloy suitable for use in metal-ceramic restorations. Due to the stress generated by masticatory forces, alloys for dental restor...
