Adherence of oral streptococci to keratinized and nonkeratinized human oral epithelial cells.
The ability of Streptococcus mutans, Streptococcus sanguis, Streptococcus mitis, and Streptococcus salivarius to adhere to keratinized versus nonkeratinized human oral epithelial cells was compared. S. mitis and S. salivarius exhibited significantly greater adherence to keratinized cells than to nonkeratinized cells. S. mutans and S. sanguis adhered equally well to either epithelial cell type. It is concluded that keratinization of epithelial cells may be a significant factor in the adherence of certain oral streptococci to the oral mucosa.
