Abstract

Several thermoplastic denture base resins have been introduced for the fabrication of non-metal clasp dentures. Although the surface of these materials is easily damaged, the surface roughness and characteristics of scratches created have not been evaluated. The purpose of this study was to evaluate the surface roughness of thermoplastic resins using a scratch test for the development of future materials. Four thermoplastic (polyamide: Valplast(®); VLP and Lucitone FRS(®); FRS, polyethylene terephthalate: EstheShot(®); ES, and polyester: EstheShot Bright(®); ESB) and two conventional acrylic (Heat-polymerizing: Urban(®); HC, and Pour type auto-polymerizing: Pro-Cast DSP(®); PR) denture base resins were examined. Eight specimens, approximately 10mm×10mm×30mm in size, of each material were fabricated. Scratch test was performed by a scratch tester with a diamond indenter of 10-μm radius and cone angle 90°, applying a constant load of 500mN, and 2-mm-long scratches were made. The scratch marks were studied under 3D laser measuring microscope and cross-section profiles at approximately 0.5mm, 1.0mm, and 1.5mm from the starting point were extracted and measured with analysis software. Data from 24 cross-section profiles in each dent...Continue Reading

Candidiasis

Candidiasis is a common fungal infection caused by Candida and it can affect many parts for the body including mucosal membranes as well as the gastrointestinal, urinary, and respiratory tracts. Here is the latest research.

Cat-scratch disease

Cat-scratch disease, a relatively common infectious disease, is caused by Bartonella henselae and characterized by a fever and regional lymphadenitis. Here is the latest research.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Candidiasis is a common fungal infection caused by Candida and it can affect many parts for the body including mucosal membranes as well as the gastrointestinal, urinary, and respiratory tracts. Here is the latest research.

Bartonellosis

Bartonellosis is an infection caused by bacteria in the genus Bartonella and can present as a variety of diseases depending on the organism involved. While asymptomatic infection has been reported, immunocompromised individuals are more susceptible to severe infection. Find the latest research on bartonellosis here.
