background: chewing-gum may serve as an effective oral hygiene device when brushing may not be possible. the aim of the present study was to evaluate the effect of chewing sugar-free gum twice a day after meals in addition to tooth brushing on dental plaque and interdental debris.     methods: twenty four (12 males and 12 females aged 20-21 years) healthy third-year dental students participated...

rectangular waveguide (wr) is one of the earliest types of transmission lines. rectangular waveguide can be produced by hot extrusion process. in this paper, the hot extrusion process of cuzn5 rectangular waveguide was investigated by finite element method (fem). in addition, genetic algorithm method (ga) was used to optimize the die geometry and process conditions to achieve the lowest magnitu...

The study was carried out, to explore the potentiality of extrusion technology for elimination of antinutritional components of cereal brans. Extrusion variables were moisture content (14, 17 and 20 %) and temperatures (115 °C, 140 °C, 165 °C). Phytic acid, polyphenols, oxalates, trypsin inhibitor, bulk density and color of brans after extrusion were analyzed. All four raw bran samples had high...

BACKGROUND To compare the amount of debris extruded apically by using conventional syringe, Endovac & Ultrasonic irrigation. MATERIALS & METHODS Thirty freshly extracted mandibular premolars were selected, working length was determined and mounted in a debris and collection apparatus. The canals were prepared. After each instrument change, 1 ml. of 3% sodium hypochlorite was used as irrigatio...

Background: Giardia lamblia is the most frequent human intestinal protozoan worldwide. Diagnosis of G. lamblia by microscopic examination of stool is common, but ELISA & IFA methods have been used in research and epidemiological studies recently. To produce polyclonal antibodies for designing ELISA & IFA kites molecular and genomic studies (PCR and parasitic culture) as well as other epidemiolo...

Co-extrasion involves extrasion of multiple layers at the same time. Functionally graded materials comprising various layers with different properties can be produced through co-extrusion. Rheological control is vital for successful co-extrusion of layered cement-based materials. The paste flow in the barrel and the die land in a ram extruder should be plug-like, while the paste should be shear...

PURPOSE To evaluate the characteristics of patients with anophthalmic cavity who developed sphere extrusion. METHODS A retrospective observational study was done evaluating 37 patients with anophthalmic cavity and sphere extrusion at the "Faculdade de Medicina de Botucatu-UNESP". RESULTS Extrusion was observed in enucleated and eviscerated cavities. The majority of the patients had the eye ...
