Zusammenfassung:Oral candidiasis is an opportunistic infection caused primarily by Candida albicans. However, in recent years, species of non-albicans Candida have been implicated more frequently in mucosal infection. Candida species usually reside as commensal organisms and are part of normal oral microflora. Determining exactly how transformation from commensal to pathogen takes place and how it can be prevented is continuous challenge for clinical doctors. Candidal adherence to mucosal surfaces is considered as a critical initial step in the pathogenesis of oral candidiasis. Acrylic dentures, acting as reservoirs, play an important role in increasing the risk from Candida colonisation. Thus, this review discusses what is currently known about the adhesion of non-albicans Candida species of oral origin to buccal epithelial cells and denture acrylics. Infekcija gljivom roda Candida predstavlja problem od sve veceg klinickog znacaja. U poslednje dve decenije, prevalencija oralne gljivicne infekcije je enormno povecana, verovatno zbog povecanja populacije imunokompetentnih pacijenata. Oralna kandidijaza je oportunisticka infekcija primarno izazvana C. albicans. Medjutim, u poslednjih nekoliko godina uoceno je da je ova infekcija mnogo cesce izazvana vrstama roda non-albicans Candida. Candida kao komenzal cini deo normalne mikroflore usne duplje. Poznavanje nacina transformacije iz komenzala u patogenu formu, i kako se ona moze spreciti, je neprekidan izazov za klinicke lekare. Adhezija gljive roda Candida za povrsinu sluzokoze predstavlja kritican, prvi korak za naseljavanje i nastanak infekcije, kao i u patogenezi oralne kandidijaze. Akrilatne proteze, delujuci kao rezervoari gljive Candida, igraju vaznu ulogu u povecanju rizika od naseljavanja usne duplje. Zbog toga je u ovom radu prikazan pregled literature koji se odnosi na adheziju oralnih izolata non-albicans Candida spp. za epitelne celije usne duplje i akrilatne proteze.
