The Portland cement was sterilized by ethylene oxide. MTA and Portland cement show comparative biocompatibility when evaluated in vitro and in vivo.

48 MTA MENTE ET AL MTA MENTE ET AL Johannes Mente, DMD, et al J. Endo May Mineral Trioxide Aggregate or Calcium Hydroxide Direct Pulp Capping: An Analysis of the Clinical Treatment Outcome 5 years, 167 teeth 78% success MTA, 60% Ca(OH) 2 i.e. Twice as much failure with Ca(OH) 2

49 Mente, DMD, et al J. Endo May 2010 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.
