This study evaluated heat-polymerized (HPR) and microwave-polymerized acrylic resins (MPR), after immersion in water, 1% hypochlorite and Ricinus communis solution (RC). Knoop hardness, color alteration, roughness and flexural strength tests were performed after obtaining the specimens and after time intervals of 15 (T) and 183 (T) days. Variations in data (∆) were submitted to ANOVA and Tukey ...

OBJECTIVE To develop an oral hygiene complex intervention and evaluate its feasibility in a single UK stroke centre. BACKGROUND Oral hygiene interventions might improve clinical outcomes after stroke but evidence-based practice is lacking. MATERIALS AND METHODS We used a sequential mixed methods approach and developed an oral hygiene complex intervention comprising: (i) web-based education ...

The aim of this study was to assess the impact of titanium nitride coatings on CoCr alloy metal parts in framework dentures on human palatal epithelium cytology compared to framework dentures made with the same alloy but without titanium nitride coating, and to acrylic dentures. Every prosthetic restoration introduced into the oral cavity and remaining in direct contact with the palate exhibits...

OBJECTIVE Candida albicans and its non-albicans counterparts, such as C. tropicalis, C. krusei, C. glabrata and C. dubliniensis, are the major etiological agents of oral candidosis. Their adherence to buccal epithelial cells (BEC), denture acrylic surfaces (DAS) and cell surface hydrophobicity (CSH) are attributes associated with yeast colonization and infection. Chlorhexidine gluconate (CG) is...

UNLABELLED To preserve oral health and to maintain the prosthetic devices, it is important not only to improve the properties of commonly known hygiene products, but also to investigate new materials with antimicrobial action. Objectives This study evaluated the antimicrobial activity of sodium hypochlorite (0.25% and 0.50%) and 10% Ricinus communis' solutions against specific microorganisms. ...

Although the effectiveness of chemical cleansing against Candida albicans biofilm has been shown, the effective concentration of denture cleanser tablets has not been studied. The aim of this study was to assess the effect of three denture materials against Candida albicans biofilm and to determine effective concentrations of denture cleanser tablets. The surface-roughness of Acron-hi™, QC-20™ ...

Poly(methyl methacrylate) (PMMA)/hydroxyapatite (HA) composite has potential application in denture base materials. The denture base materials should exhibit good mechanical properties and dimensional stability in moist environment. Silane coupling agent [3-methacryloxypropyltrimethoxy silane (γ-MPS)] was used to treat the HA fillers in order to enhance the interfacial interaction between the P...

BACKGROUND Appropriated denture hygiene is a predictive factor for longevity of rehabilitation treatment and maintenance the oral mucosal health. Although, disinfectant solutions are commonly used as cleansers, impact these on acrylic resin-based dentures remain unclear. OBJECTIVE To evaluate, in vitro, antibiofilm activity complete their effects physical mechanical properties resin. METHODOLOG...

denture stomatotos os a common problem of the denture wears, and it's etiology is not clear from the literatures. some studies show that the aetiology is candida albicans, while other reports point out the other agents including candida albicans. the present study was designed to evaluate the prevalence of oral candidiasis in patients using complete denture with different datas. 50 subject...
