Denture base resins are extensively used in dentistry for a variety of purposes. These materials can be classified as chemical, heat, light, and microwave polymerization materials depending upon the factor which starts the polymerization reaction. Their applications include use during denture base construction, relining existing dentures, and for fabrication of orthodontic removable appliances....

The aim of this study was to detect and quantify the main residual monomers released from composites, using high performance liquid chromatography (HPLC). Discs were made with dental composites (Herculite XRV, Tetric Ceram and Filtek Z250) and immersed in deionized water at 37°C for 28 days, with water changes in 1, 7, 14 and 21 days. The mean concentration of residual monomers were subject to ...

The study evaluated the effect of different acidic salivary pH values on monomer leaching and surface roughness conventional CAD/CAM processed (milled 3D-printed) denture base materials. High-performance liquid chromatography was used to determine quantity residual methyl methacrylate after 30 days immersion in saliva. (Ra) before incubation recorded using a non-contact optical profilometer. te...

Defects of the eye may follow removal of a part of or the entire orbit. This results in the patient becoming visually, esthetically and psychologically handicapped. Restoring the defect with a silicone- or acrylic-based prosthesis not only restores esthetics but also gives back the lost confidence to the patient. This is a case report of a patient with a 'pthisical eye' and details the steps in...

Melamine formaldehyde (MF) resins have been synthesized at different reaction temperature and pH values. Different molar ratios of melamine and formaldehyde were used to synthesize the corresponding resins. The prepared resin samples were characterized by using molecular weight determination viscometry and thermogravimetric analysis (TGA). The maximum percentage of solid content (69.7%) was obt...
