BACKGROUND. Human chorionic gonadotropin (hCG) is a glycoprotein hormone comprised of two dissimilar subunits (α and β) and normally is synthesized by trophoblastic tissue. Although hCG expression has been identified in a variety of neoplastic tiss

Secondary caries is one of the major reasons causing restoration failure; however, little is known of its microbial etiology, mainly because of the difficulties in eliminating bacterial contamination during collection and sample preparation. Therefor
