ABSTRAKT

We perform in vitro validation of two plasma systems to determine whether bacteria inactivation occurs in a root canal abscess during root canal dental surgery. Results indicate that plasma may be a very effective tool for minimally invasive inactivation of bacteria deep inside the tooth, without causing excessive damage to the tooth surface. We show effective inactivation of ~ 104 colony forming units of Enterococcus faecalis following 10-s treatment by nanosecond-pulsed corona discharge that is ignited using a standard dental tool (Pathfinder®) as the plasma guide.
