STATEMENT OF PROBLEM Hard denture acrylic resins must maintain color stability to remain esthetic. PURPOSE The purpose of this in vitro study was to measure the color stability of denture resins subjected to staining agents and cleaned with denture cleansers MATERIAL AND METHODS Forty-five disks (10-mm diameter, 2-mm thick) fabricated from 3 denture resins (light polymerized Eclipse; heat p...

AIM To evaluate the effect of successive cycles of disinfection in different denture cleansers on the surface roughness and the Vickers hardness of two layers of acrylic resin (base-BL and enamel-EL) of two commercial cross-linked artificial teeth. MATERIALS AND METHODS The occlusal surfaces of 60 acrylic resin denture posterior teeth (Trilux-TLX and SR Orthosit PE-SRO) embedded in autopolyme...

In this investigation the denture retention was measured and the influence of denture -retention on ima'sticatory efficiency was examined. The investigation was iperf armed on 36 comiplete denture wearers. The test of masticatory efficiency wals used according to Ni'kšić (1965). The meaisuriinig of denture retention was made by specially constructed mechanical scale, which wa's designed so that...

PURPOSE Difficulty in cleaning resilient denture liners remains a material disadvantage. The purpose of the present study was to evaluate the effect of denture cleansers on hardness of resilient liner materials. MATERIALS AND METHODS Three resilient liners, Luci Sof (Dentsply), Molloplast-B (Dentax), and Sofreliner (Tokuyama), and two denture cleansers, Efferdent (Warner-Lamber), and 0.5% alk...

OBJECTIVE Since dentures can serve as a reservoir for halitosis-causing oral bacteria, halitosis development is a concern for denture wearers. In this study, we surveyed the prevalence of four selected halitosis-related species (Fusobacterium nucleatum, Tannerella forsythia, Veillonella atypica and Klebsiella pneumoniae) in clinical denture plaque samples, and developed denture biofilm models f...

Background and Objectives: Denture cleanser is the most widely used method by patients to maintain clean healthy dentures but prolonged use of such cleansers may affect properties denture. The present study was carried out evaluate effect three prepared denture which were 4% citric acid, tartaric oxalic acid in addition Protefix a commercially available cleansers, on some mechanical physical (c...

background hygiene and maintenance of removable prostheses are very important for the oral health. elderly patients are not capable of this affair since they might have diseases in addition to being old; thus, they require new alternative methods. objectives the purpose of this study was to compare the disinfecting effects of three substances, water, normal saline and denture cleaning tablets c...

AIM This study aimed to verify the influence of oral environment and denture cleansers on the surface roughness and hardness of two different denture base materials. METHODS A total of sixteen identical removable disc specimens (RDS) were processed. Eight RDS were made from heat-cured acrylic resin (AR) and the other eight were fabricated from thermoplastic injection moulded resin (TR). Surfa...
