The combination of sodium hypochlorite (NaOCl) and
chlorhexidine (CHX) results in the formation of a
precipitate. The aim of this study was to determine the minimum concentration of
NaOCl required to
form a precipitate with 2.0% CHX. This was accomplished with a serial
dilution technique. X-ray
photon spectroscopy (XPS) and time-of-flight secondary ion mass
spectrometry (TOF-SIMS) were
used to qualify and quantify the precipitate. A color change and
precipitate were induced in
2.0% CHX by 0.023 % and 0.19 % NaOCl, respectively. Both XPS and TOF-SIMS
showed the presence
of para-chloroaniline in an amount directly related to the
concentration of NaOCl used. Until this
precipitate is studied further, its formation should be avoided by
removing the NaOCl before placing
CHX into the canal.
The
effectiveness of traditional endodontic intracanal medications in reducing
bacterial numbers
and
preventing acute flare-ups and pain continues to be questioned. In the present
study, a new
local
delivery device was developed that releases a substantive dose of clindamycin
into root
canals.
Clindamycin-impregnated ethylene vinyl acetate (EVA) fibers were produced, and
the sensitivity of
common endodontic microbes to the fibers were established. An in vitro model was
developed to
persistently infect 32 extracted human teeth with endodontic pathogens to test
the efficacy of the
clindamycin/EVA fibers in reducing the number of colony-forming units. The
clindamycin/EVA fibers
were shown to be effective in reducing growth of common endodontic microbes
on blood agar plates,
and in significantly reducing growth of Prevotella intermedia,
Fusobacterium nucleatum, and
Streptococcus intermedius in extracted human teeth, thus indicating merit
in further exploring
the potential
of these fibers as intracanal medications.
