BACKGROUND Regular usage of denture cleansers is recommended in complete denture wearers for effective plaque control, and these cleansers alter the physical properties of acrylic resin over a period of time. Thus, an in vitro study was carried out to assess the effect of denture cleansers on the color stability of heat-cure denture base resin. AIM The aim of the present study was to evaluate...

PURPOSE The purpose of this study was to evaluate the effect of differences in the retainer design on load on abutment teeth and displacement of the denture base in mandibular unilateral extension base partial removable dental prosthesis to determine the optimum design for a mechanically appropriate retainer. METHODS Three models were used. Each incorporating a removable denture with differen...

BACKGROUND Fractures of acrylic resin dentures are a common occurrence in clinical dentistry. The denture may be fractured accidentally when dropped or while in service in the mouth due to flexural fatigue. OBJECTIVES The aim of this study was to compare the elastic modulus and the flexural strength between two heat-cured acrylic resins used in denture bases: a high-impact resin (Lucitone 199...

The surface of heat-cured acrylic resin on the base artificial teeth has a risk roughness. Its causes are liquid absorption and chemical processes. Fluid can be affected by immersion in denture cleaners containing sodium bicarbonate. This study aims to determine effect cleanser 48% bicarbonate changes resin's used 16 specimens (brand Meliodent) was square size 10x10x2.0 ± 0.5 mm. samples' rough...

While investigation of the microbiome on natural oral surfaces has generated a wealth of information, few studies have examined the microbial communities colonizing dentures and their relationship to oral health. To address this knowledge gap, we characterized the bacterial community associated with dentures and remaining teeth in healthy individuals and patients with denture stomatitis. The mi...

Background and Aim: The hardness and wear resistance of denture teeth have great importance in the longevity of dentures. This study assessed the effect of 0.2% chlorhexidine (CHX) and alcohol-free Listerine on the microhardness of acrylic denture teeth. Materials and Methods: In this in-vitro experimental study, 26 Major Plus teeth were randomly divided into three groups for immersion in 0.2%...

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...

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...
