Characterization of dental epithelial progenitor cells derived from cervical-loop epithelium in a rat lower incisor.

abstract：:Growing evidence suggests that individual genetic susceptibility may influence the host's response to infections. The aim of this project was to study whether gene polymorphisms of inflammatory markers are associated with the presence of viable periodontopathogenic bacteria. We extracted genomic DNA from 45 young adul...
