conclusions coffee caused the most color changes in the examined resin denture teeth. tea and cola left less staining on the teeth, and distilled water caused the least discoloration. generally, investing by heat- and cold-cured acrylic resins can significantly affect the color stability of resin denture teeth; however, heat-cured acrylic resins had fewer color changes. results there were signi...

Purpose: Denture-related stomatitis is probably the most common form of oral candidiasis and its reported prevalence varies widely ranging up to 65%. In this in vitro study, we evaluate the effect of delmopinol application on Candida albicans adherence on heat-cured acrylic resin, cold-cured acrylic resin and microwave-cured acrylic resin. Materials and methods: A total of 40 specimens of each ...

Background: Heat cured acrylic resin is the most widely used material in the manufacture ofdenture base, but has mechanical properties weakness (transversal strength and impact strength). Alternative to increase the mechanical properties of acrylic resin is the utilization of reinforcing fibre that is polyethylene fibre that has advantage such as good aesthetic, easy to manipulate and increase ...

The purpose of this study is to compare the flexural strength values of four different methods for chair side direct transfer methods of implant housing. Materials and Methods: Sixty heat-cured polymethylmethacrylate denture blocks were prepared of size 11 (±0.5) x 8 (±0.5) x 38(±0.5) mm. At the centre a hole of 5mmx8mm dimension was made to secure the implant housing.The Implant Housings were ...

INTRODUCTION It is unknown how the use of a light-cured acrylic resin is appreciated over the traditional chemically cured resins for the construction of custom trays in a teaching environment. OBJECTIVE To evaluate the acceptance of light-cured acrylic resin for custom trays by dental students. METHOD A questionnaire addressing the use and handling properties of both light-cured (Megatray,...

Aim: The aim of this study was to evaluate the transverse strength of three kinds of heat-cured acrylic resin (Meliodent HC, Acron HC, Lucitone 199); one kind of microwave-cured acrylic resin (Acron MC); one kind of visible light-cured resin (Triad VLC); and one kind of self-cured acrylic resin (Meliodent SC). Method: A total of 60 specimens (65 mm x 10 mm x 3 mm) were fabricated, ten from each...

BACKGROUND Acrylic teeth have long been used in the treatment of a complete denture. One of the primary advantages of acrylic teeth is their ability to adhesively bond to the denture base resins. Although the bonding seems satisfactory, however, bond failures at the acrylic teeth and denture base resin interface are still a common clinical problem in prosthodontics. The purpose of this study wa...

Introduction: Acrylic resins have been used successfully as denture bases. However, acrylic resin denture base materials are brittle and have poor strength and thermal conductivity. Therefore, it is essential to improve the flexural strength of heat polymerized acrylic resin. The present study aimed to evaluate and compare the flexural strength of heated polymerized acrylic res...

BACKGROUND Despite drawbacks, cold-cured acrylic resin is still the most common material used in denture repair. Zirconia nanoparticles were among the reinforcements added to increase the strength of the resin. The effect on Candida due to the addition of zirconia nanoparticles to the resin has not been investigated. PURPOSE The aim of this study was to evaluate the effect of zirconia nanopar...
