Among them, dental caries continues to be the single most prevalent and costly oral infectious disease （Marsh, 2003; Dye et al., 2007）. Dental caries results from the interaction of specific bacteria with constituents of the diet within a dental biofilm known as plaque （Bowen, 2002）. Sucrose is considered to be the ＂arch criminal＂ from the dietary aspect because it serves as a substrate for synthesis of extracellular （EPS） and intracellular （IPS） polysaccharides in dental biofilm and is also fermentable （Bowen, 2002）.展开更多

The results show that demographic characteristics are still an important factor influencing farmers' identification of entrepreneurial opportunity,but the extent of its influence is weaker than entrepreneurs' trait. The new trait theory is verified in farmers' entrepreneurship opportunity behavior; entrepreneurship environment is becoming an important factor influencing entrepreneurial opportunity identification,whose regulation effect on entrepreneurs' social network and previous experience is stronger than the regulation effect on entrepreneurs' psychological trait.展开更多
