Another possible cause is the potential resistance these bacteria might possess against calcium hydroxide, which is the antibacterial medication most commonly used within the root canal system during endodontic therapy which would allow these micro-organisms to remain in quiescent state.Enterococcus faecalis persistence has been attributed to its ability to resist the high pH of calcium hydroxide, material which is frequently introduced in the canals, and preserved in that location for at least a week.
La persistencia de Enterococcus faecalis se ha atribuido a su capacidad para resistir el elevado pH del hidróxido de calcio, el cual frecuentemente se introduce en los canales y se mantiene en ellos durante al menos una semana.
