In dieser Studie wird die Wirksamkeit von Calciumhydroxid (Ca(OH)2), Parachlorphenol (PCP) und mit Kampfer versetzten Parachlorphenol (CHKM) auf E. Faecalis verglichen. Dabei zeigten sich CHKM und PCP nach 1-tägiger Anwendung überlegen gegenüber Ca(OH)2 bei dreitägiger Anwendung, wobei CHKM am wirksamsten war, gefolgt von Ca(OH)2. Dies ist ein besonders interessantes Ergebnis, da der Zusatz von Kampfer einerseits die Wirksamkeit erhöht, andererseits aber auch die ätzende Wirkung von Parachlorphenol aufhebt.

The aim of the present study was to develop an in vitro test model from human
teeth to comparatively examine antibacterial effectiveness of calcium hydroxide,
parachlorophenol (PCP) and camphorated parachlorophenol (CPCP) against
Enterococcus faecalis in infected root canals. Cylindrical dentin specimens were
prepared from freshly extracted human maxillary anterior teeth. The specimens
were inoculated with E. faecalis and then medicated with either CPCP, PCP or
Ca(OH)2. The disinfecting efficacy of these agents was tested by collecting
dentin chips from the inner ("canal") walls of the specimens and
counting viable E. faecalis. The dentin chips were diluted and a classical
bacterial count technique was used for recovery of E. faecalis strains of 5%
sheep blood agar. The effectiveness of CPCP and PCP at one day was superior to
the effectiveness of Ca(OH)2. In the three-day group, CPCP was the most
effective, followed by Ca(OH)2. The experimental model used in this study may be
useful for investigation of the effect of intracanal medicaments on
microorganisms lodged in the root dentinal tubules.
