Received: 15 October 2006 Accepted: 16 May 2007 Abstract: Objective: The purpose of this study was to evaluate the transverse strength of one brand of denture base material repaired with two autopolymerized acrylic resins with and without wire reinforcement. Materials and Methods: Eighty samples (2.5×10×65 mm) were fabricated and divided into five groups. The control group was left intact. Grou...

AIMS To evaluate the effect of chemical disinfectant on the transverse strength of heat-polymerized acrylic resins subjected to mechanical and chemical polishing. MATERIALS AND METHODS A total of 256 rectangular specimens (65 * 10 * 3 mm) 128 per resin (Lucitone-199 and Acralyn-H) were fabricated. One side of each specimen was not polished and the other was either mechanically (n = 96) or che...

Denture stomatitis is a disease involving C. albicans, which can affect elderly and immuno-compromised people. To avoid any recurrence of this pathology, it necessary to treat patients regularly disinfect dentures. However, the denture cleansers’ efficacy not optimal often leads adverse color effects on base resins. The aim study was investigate low-pressure non-thermal O2 plasma (NTP) treatmen...

PURPOSE Poly(methyl methacrylate) (PMMA) has been widely used as a denture-base acrylic resin due to its excellent physical and mechanical properties. However, the material is highly prone to microbial fouling that often leads to Candida-associated denture stomatitis. Incorporation of phosphate groups into PMMA could facilitate adsorption of salivary antimicrobials and inhibit microbial adheren...

Acrylic resin bases of removable dentures attract stains and odor-producing organic and inorganic deposits. The use of chemical denture cleanser soaks is the most popular method of denture cleansing. This study was undertaken to compare the efficacy of two different denture cleansers--sodium perborate (Clinsodent) and sodium hypochlorite (VI-Clean)--in removing tea, coffee, turmeric and tobacco...

This study aimed to evaluate the tensile and transverse bond strength of chairside reline resins (Tokuyama Rebase II, Mild Rebaron LC) to a thermoplastic acrylic resin (Acrytone) used for non metal clasp denture. The results were compared with those of a conventional heat polymerized acrylic resin (Paladent 20) and a thermoplastic polyamide resin (Biotone). The failure sites were examined by sc...

Objectives Acrylic resins are one of the most important denture base materials in dentistry due to their favourable mechanical and physical properties. The purpose of present study is to compare 4 available acrylic flexural strength properties before and after thermocycling. Methods Acrylic resin specimens of Meliodent (Heraeus Kulzer, Hanau, Germany), Vertex (Vertex-dental BV, Zeist, Netherla...

Acrylic resins are used as denture base materials since 1937 (Craig, 1993) and heat-cured Poly(methyl-methacrylate) (PMMA) (Lay et al., 2004) composed by methyl methacrylate monomers chains is the most popular of them. Virtually, dentures are constructed from conventional polymer/monomer (Lay et al., 2004) processed by heat water-bath system and compression molding technique (Ganzarolli et al.,...
