Abstract :Abstract   Aim: C Aim: Candida species, although being a member of the oral flora, may exhibit pathological features under certain conditions. The aim of this study was to determine the distribution and biofilm production of Candida species that were isolated from denture related stomatitis insert ignore into journalissuearticles values(DRS); patients and to compare with healthy subjects. andida species, although being a member of the oral flora, may exhibit pathological features under certain conditions. The aim of this study was to determine the distribution and biofilm production of Candida species that were isolated from denture related stomatitis insert ignore into journalissuearticles values(DRS); patients and to compare with healthy subjects. Materials and Methods: The 56 non-smoker, systemically healthy, maxillary removable denture wearer subjects included in this study and diagnosed as DRSinsert ignore into journalissuearticles values(N=27); and healthyinsert ignore into journalissuearticles values(N=29); . Samples from the palatal mucosal surface of patients were collected by sterile swabs during 20 seconds. Cultivation and selective isolation of Candida species were performed on CHROMagar insert ignore into journalissuearticles values(CHROMagar ® Candida, CHROMagar, Paris, France); at 37ºC for 2 days. Isolated Candida species were identified with API ID 32 C insert ignore into journalissuearticles values(bioMérieux ® , France);. Biofilm formation by Candida species were determined by a visual tube method. Results: The prevalence of the yeasts in the healthy group was found to be 37.94%, while in the DRS group it was 100% insert ignore into journalissuearticles values(p<0.001);. The isolation rate of C. albicans in patients with DRS significantly higher insert ignore into journalissuearticles values(p<0.001);. Biofilm formation was observed in a total of 37 oral yeast isolates, 9 isolates from healthy denture wearers and 28 isolates from DRS patients. The number of C. albicans and C. glabrata isolates showing biofilm formation ability in the DRS group was significantly higher than the healthy group insert ignore into journalissuearticles values(p<0.05);. Conclusions: Within the limitations of this study, our results suggest that Candida species play a major role on the development of DRS. While C. albicans was the most isolated species in DRS, C. glabrata was as important as C. albicans on the pathogenesis of DRS.   keywords: Biofilms , Candida, denture stomatitis, mycology, oral pathology HAREKETLİ PROTEZ KULLANAN HASTALARDA KANDİDA TÜRLERİNİN KOLONİZASYONUNUN VE BİYOFİLM OLUŞTURMA KAPASİTELERİNİN DEĞERLENDİRİLMESİ Öz Amaç: Candida türleri, oral floranın doğal üyesi olmakla birlikte, belirli koşullar altında patolojik özellikler sergileyebilir. Bu çalışmanın amacı, protez stomatiti insert ignore into journalissuearticles values(PS); olan hastalardan ve protez kullanan sağlıklı bireylerden elde edilen Candida türlerinin dağılımını ve biyofilm üretime kapasitelerini karşılaştırmaktır Gereç ve Yöntem: Sigara içmeyen, sistemik olarak sağlıklı, maksiller tam damak protez kullanan 56 kişi bu çalışmaya dahil edildi. Katılımcılar PS   insert ignore into journalissuearticles values(N = 27); ve sağlıklı insert ignore into journalissuearticles values(N = 29); olmak üzere gruplandırıldı. Hastaların palatal mukoza yüzeyinde 20 saniye boyunca steril swablar gezdirilerek sürüntü örnekleri elde edildi. Candida türlerinin kültivasyon ve seçici izolasyonu 2 gün boyunca 37 ° C\`de CHROMagar insert ignore into journalissuearticles values(CHROMagar® Candida, CHROMagar, Paris, Fransa); besiyerinde gerçekleştirildi. İzole edilen Candida türlerinin identifikasyonu API ID 32 C insert ignore into journalissuearticles values(bioMérieux®, Fransa); ile gerçekleştirildi. Candida türlerinin biyofilm oluşturma potansiyelleri görsel tüp yöntemi ile saptandı Bulgular: Sağlıklı gruptaki mayaların prevalansı % 37.94 iken, PS grubunda % 100\`dü insert ignore into journalissuearticles values( p <0.001);. PS\`li hastalarda C. albicans \`ın izolasyon oranı anlamlı derecede daha yüksekti insert ignore into journalissuearticles values( p <0.001);. Sağlıklı katılımcılardaki 9 PS katılımcılardaki 28 izolatta biyofilm oluşumu gözlendi. PS grubunda biyofilm oluşumunu gösteren C. albicans ve C. glabrata izolatlarının sayısı sağlıklı gruba göre anlamlı olarak yüksekti insert ignore into journalissuearticles values( p <0.05);. Sonuç: Bu çalışmanın sınırları dahilinde, sonuçlarımız Candida türlerinin PS\`nin gelişiminde önemli bir rol oynadığını göstermektedir. C. albicans , PS\`de en sık izole edilen tür olsa da C. glabrata da PS\`nin patogenezinde C. albicans kadar önemlidir.
