The Effect of Probiotic Lactobacillus acidophilus and Ethanolic Propolis Compound toward Nucleic Acid Deposition in the Extracellular Polymeric Substance of Root Canal Bacteria.

Objective:  This study aimed to evaluate the effects of ethanolic propolis and probiotic bacteria on the nucleic acid concentration in the extracellular polymeric substances (EPS) derived from biofilm of root canal bacteria.

Materials And Methods:  Clinical bacteria of the root canal were cultured with ethanolic extract of propolis (EEP; 10 or 0.1%) and .
