The main purpose of this study is to examine the process of denture plaque formation and relationships between denture plaque and fibronectin. Plasma fibronectin has been detected in dental pellicle and dental plaque, and the capacity of the cells to bind gram-positive or gram-negative bacteria was shown. Three types of experimental denture plate were set in oral cavities of subject with normal dentition, for 1, 3 and 6 days. Obtained samples were staining with FITC labeled anti-aerobic bacteria rabbit serum, FITC labeled anti-anaerobic rabbit serum and FITC labeled anti-Candida rabbit serum and each of them were stained with RITC labeled anti-fibronectin goat immunoglobulins. They were observed by fluorescence microscopy. Fibronectin was found on all kinds of experimental denture plate, and existed positions are mainly equal to adherence of aerobic bacteria, anaerobic bacteria and Candida albicans.'this study shows that fibronectin is siguaificantly related to the formation of denture pellicle and denture plaque. The results play an important role that fibronectin might be correlated to the initial formation of the denture plaque.
