Microleakage at the junction between the metal alloy and acrylic resin in a removable partial denture may result in discoloration, fluid percolation, and acrylic resin deterioration and Failure of a removable partial denture. Dye penetration test was conducted on eighty specimens each of Nickel-Chromium/Cobalt-Chromium metal-Heat cure acrylic resin. Samples were randomly divided into eight grou...

Detecting water hazards is a significant challenge to unmanned ground vehicle autonomous off-road navigation. This paper focuses on detecting the presence of water during the daytime using color cameras. A multi-cue approach is taken. Evidence of the presence of water is generated from color, texture, and the detection of reflections in stereo range data. A rule base for fusing water cues was d...

Purpose: The aim of this study was to evaluate the effect of oral microorganism on surface topography of acrylic resin denture base material. Materials and methods: Fifty rectangular plates of dimensions 30mm x 20mm x 1 mm were fabricated with heat polymerizing acrylic resin denture base material. an area of 10mm x 10 mm in the center of each acrylic plate was marked for evaluation of surface t...

Failure of the bond between acrylic teeth and the denture base resin interface is one of the major concern in prosthodontics. The new generation of denture bases that utilize alternate polymerization methods are being introduced in the market. The aim of the study is to evaluate the influence of polymerization methods on bonding quality between the denture base and artificial teeth. Sixty test ...

Paint systems containing color-change or fluorescing compounds were found to be sensitive to underlying corrosion processes by reacting to the pH increase associated with the cathodic reaction that accompanies corrosion. The sensitivity of acrylic-based coating systems for detection of cathodic reactions associated with corrosion was determined by applying constant cathodic current and measurin...

Fluorinated denture base acrylic resins can present more stable physical properties when compared with conventional polymers. This study evaluated the incorporation of a fluoroalkyl methacrylate (FMA) mixture in a denture base material and its effect on roughness and flexural strength. A swelling behavior assessment of acrylic resin specimens (n=3, per substance) after 12 h of FMA or methyl met...

STATEMENT OF PROBLEM Despite the numerous positive features of acrylic denture base, there are a number of undeniable associated disadvantages. The properties of denture base have been improved through various interventions including application of different types of filler and coatings. OBJECTIVES This study aimed to evaluate the surface roughness, thickness and coating quality of organic-in...
