Assessment ofCandidaspecies colonization and denture-related stomatitis in complete denture wearers

Abstract

Candida species are considered the primary causative agents of denture stomatitis, but their role in colonization and disease in denture wearers remains undefined. In this study, we investigated risk factors associated with progression to Candida-related denture stomatitis in patients using complete dentures, and we genetically identified Candida isolates associated with disease and colonization. We recruited 114 retirement home residents for this study, from whom oral mucosa samples were collected and cultured following oral cavity exams. Morphologic analysis was used to identify potential yeast-positive cultures, which were then characterized further by RFLP analysis. C. albicans was the most frequently recovered species (61; 41.5%), followed by C. glabrata (27; 18.4%), and C. tropicalis (19; 12.9%). In addition, 16 isolates (10.9%) of C. dubliniensis were recovered, which was the first identification of this species in clinical samples from Iran. This study demonstrated a significant association between the duration of denture wear and oral candidiasis. Furthermore, we noted a high prevalence of C. dubliniensis in complete denture wearers.

Color Stability, Surface Roughness and Flexural Strength of an Acrylic Resin Submitted to Simulated Overnight Immersion in Denture Cleansers

“…In this sense, denture hygiene simulating the overnight immersion (8 h) represents a common situation for patients, as dentists commonly recommend denture removal during the sleeping period and immersion in solutions in order to relieve the underlying tissues and clean the dentures (18). Therefore, the aim of this study was to evaluate the alterations of color, flexural strength and surface roughness of acrylic resin after immersion in solutions of NaOCl and alkaline peroxide, simulating an overnight use for one year and a half.…”

Time-related surface modification of denture base acrylic resin treated by atmospheric pressure cold plasma

“…Chronic atrophic candidiasis, also known as Candidaassociated denture stomatitis, is a very common disease affecting 15% to over 70% of the denture wearers [1][2][3][4][5][6] . Candida albicans has been known as the most frequently isolated Candida species responsible for this inflammatory pathology 2,[4][5][6] .…”

“…Candida albicans has been known as the most frequently isolated Candida species responsible for this inflammatory pathology 2,[4][5][6] . The adherence of C. albicans to acrylic resin denture base (polymethyl methacrylate -PMMA) has been thought to be the first step for successful colonization before subsequent plaque formation and development of pathogenesis 7,8) .…”
