Color difference threshold determination for acrylic denture base resins.
This study aimed to set evaluation indicators, i.e., perceptibility and acceptability color difference thresholds, of color stability for acrylic denture base resins for a spectrophotometric assessing method, which offered an alternative to the visual method described in ISO 20795-1:2013. A total of 291 disk specimens 50±1 mm in diameter and 0.5±0.1 mm thick were prepared (ISO 20795-1:2013) and...
متن کاملEffect of Staining Solutions on Color Stability of Acrylic Denture Base Resins - A Spectrophotometric Evaluation
The purpose of this study was to quantitatively evaluate the effect of staining solutions by spectrophotometric method on color stability of the commercially available acrylic denture base resins polymerized by different methods of cure, materials, and immersion periods. Commercially available heat cure resin (Travelon) and self cure resin (RR repair material) were selected for the study. In ca...
متن کاملEvaluation of Cellular Toxicity of Three Denture Base Acrylic Resins
OBJECTIVE This study aimed to evaluate the cellular toxicity of two newly-released acrylic resins (Futura Gen and GC Reline Hard) in comparison with the conventional heat-cure resin (Meliodent). MATERIALS AND METHODS Sample discs from each acrylic resin were placed in 24-well culture plates along with L929 mouse fibroblast cell line. A mixture of the RPMI 1640 medium, antibiotics and 10% FBS ...
متن کاملEffect of denture cleansers on color stability, surface roughness, and hardness of different denture base resins
AIM The purpose of this study was to evaluate the effect of different denture cleansers on the color stability, surface hardness, and roughness of different denture base resins. MATERIALS AND METHODS Three denture base resin materials (conventional heat cure resin, high impact resin, and polyamide denture base resin) were immersed for 180 days in commercially available two denture cleansers (...
متن کاملPhysical properties of four acrylic denture base resins.
Resistance to impact fracture and high flexural strength are desirable properties of denture base acrylics. The purpose of this laboratory study was to determine the Izod impact strength, the flexural strength, the flexural modulus, and the yield distance for four premium denture resins. Bar specimens 86 x 11 x 3 mm of Lucitone 199, Fricke Hi-I, ProBase Hot, and Sledgehammer Maxipack were fabri...
