Direct pulp capping with Mineral Trioxide
aggregate – an Observational Study.
Over an observation period of nine years,
the authors followed 49 of 53 teeth and
found that 97.96% percent had favorable
outcomes on the basis of radiographic
appearance, subjective symptoms and
cold testing.

Saidon J et al. OSOMOPOR Endod
2003:95:483-489 “Cell and tissue
reactions to mineral trioxide
aggregate (MTA) and Portland
cement.”
MTA and Portland cement show
comparative biocompatibility when
evaluated in vitro and in vivo. The
Portland cement was sterilized by
ethylene oxide.

Dentin bridge formation with MTA seems to be more homogenous (fewer
tunnel defects) and more localized than that formed with Ca(OH)2 (20–24).
caries was excavated from the cavity walls.
Near to the pulp, except for one carious spot, the removal of which resulted
in exposure of the pulp, the cavities were routinely disinfected with 0.12%
chlorhexidine solution (Glaxo Smith Kline GmbH, Buhl, Germany).
Resolution of bleeding from the exposed pulp in less than 5minutes was
considered to be indicative of reversible inflammation
The MTA pulp cap was overlaid with a thin protective layer of resin modified
glass ionomer cement (Vitrebond; 3M Espe)
The reduction in clinical success if a direct pulp capping is not followed
immediately with permanent restoration has been shown in other clinical
studies (11, 12)
The longer the follow-up period, the more evident the trend became to a
decline in the success rate of the teeth in the Ca(OH)2 group compared
with the MTA group.
